Top 10 Skills of Developer in 2019.
Hello
friends,
How is going
all, I hope everyone is well. Let’s go today I am going to share the Top 10 Skills
of Developer in 2019.
A modest developer is a large rarity. The problem is not even in the poor knowledge of
programming language but in integrated accession. The latest developer
should not only comprehend but also fuse the latest technologies into their
work and be aware of the interrelation between innovation and the high demand for computer software. Only this developer will be the most sought after in any
company, no affair how Manu programming language he knows.
Today more
than 50 programming languages are being actively used, but the most important ones can be counted on the fingers of one hand. They constitute the great trunk of the market and bring income to programmers. Following this introduction, we
approach the first and most important skill of any developer.
Skill-1
Programming Language
In order to
be a popular and promising developer with a good monthly salary, it’s enough to
be fluent in only two or three common programming languages the listed
below:
The table
shows the programming languages, their popularity, and the platforms on which
they are used. If you are going to study the first or the new programming
language, it is worth starting not to form its prevalence, but from the goals, you
are pursuing and the areas that interest you. Let’s address the first 5
programming languages.
Python
The language
is common in various areas of development, but it is a serious rival of other languages in the following directions:
Web-Development
In recent
years, developers of the websites and apps, based on the client-server model
structure, widely use popular Python frameworks: Django (complete version with
administrator bar and interface, speed and minimal need of skills are its
advantages) and Flask (a shall that may be customized for a specific programmer
needs, it is the best option for creating a REST API – client-server
architecture style for building scalable distributed website systems and
application, as an example, the social network API)
Machine Learning:
Python has
two popular and frequently used libraries: Scikit-learn and TensorFlow, which
can be used for neural network creation, deep machine learning, as well as for analytics, and forecasting. One of the most popular primitive ways of solving
learning tasks is the “Smart” news feeds on social networks.
C++,C,C#
C language
is the ancestor of C# and C++. This programming language, like its successor,
is used to create software. The main designation of these languages is the
development of system software. The main advantage of it is the high processing
speed, which allows you to create modern, resource-intensive games and apps in
C++ and C#.
If you plan
to develop software or games (Game engines like Unreal Engine, Frostbite,
Unity), then this programming language should be learned in the first place, since in
the upcoming years it certainly will not be losing its ground in this sphere.
This is evidenced by the positive rating dynamics: none of these programming language has left the Top 7 over the past 10 years. However, it is disturbing
that this language has recently paused to develop. Except for the elaboration,
there have been no breakthrough innovations in code and algorithm improvement
for a long time.
Java
Until 2006
nobody could imagine that the Java language would be used not only in the household
equipment programming. Nowadays it is the most popular language for creating
cross-platform software with compatibility support for older code versions. It
is used to create applications, and games, synchronize devices, to develop web
services, banking, and financial systems.
One of the downsides is the lack of flexibility, hence it is currently reminding Lego. All
that you can create or write in Java is already scattered throughout the
internet. To create a mid-level Java app, you need only a minimal understanding
of programming principles and basic engine skills search in order to find
patterns of completed projects on the web. This is what made Java one of the
most popular programming languages for beginners.
As you can
see, each language is designed for its own sphere, where it looks more
promising and more convenient. Although in the light of modern realities, it is
not enough for programmers to know one language, it is much more important to
have additional skills that increase the level of the specialist’s demand.
Skill-2 Client-server
architecture
Keeping in
mind that recent developments are in 80% of cases based on the client-server
model, its understanding is rather mandatory than desirable for the developer.
Poorly designed architecture may lead to the dozens of typical problems linked
with the processing and distribution of HTTP requests. Therefore, the ignorance of
this employer’s denial.
Client-server
architecture is a system of interaction between the user’s device and server host.
The device is a client that connects to the server and delivers POST requests
via the Internet. The server, in turn, is engaged in data processing and sends
the completed solutions back to the device. Thus, it minimizes the risks of the client’s software being hacked, and also it reduces the level of the strain of the device because the main calculations are made at server architecture enabling it to save and restore client data on a new devein, If the old one failed or was
formatted.
First of
all, it is essential for the developer to understand the REST philosophy, which
was originally conceived as a system of rearrest management for interaction
between the server and the client: Get, Post, and Delete with a data relevance
handler.
Client-server
architecture is used in:
- Business automation;
- Online games;
- Commercial applications;
- Website development;
- Cloud computing.
Skill
3—Systems engineering:
Without implementing the basis of systems
engineering, it will be extremely difficult for a programmer to create a unique
and competitive product. Systems engineering is a big course, which,
unfortunately, is taught in an extremely compressed form by the majority of
educational institutions where they address the next main points only in a
shallow way:
Market analysis.
Competence
in this field will help you to analyze and examine the volatility of the market,
its movement toward technological (integration of modern technologies,
development prospects), social (wishes, the interest of users, value for the
consumer), functional (maximum of possibilities, without sacrificing UI convenience)
aspects. This approach to the development of the final product will allow you
to see the flaws and deficiencies of the idea that is always imperfect at the
initial stage and requires more accurate modeling, and a clear strategy.
Planning.
It implies a
strong prioritization and time control over task performance. It is a
condition that directly affects the development deadlines. Breaks or delays may
lead to the release of the product irrelevant to the market. The project
managers too often don't fully understand the scope of the tasks to be done and
set deadlines based on their own ideas. This leads to discrepancies between
planned deadlines and real-time frames. Therefore, the developers should be
involved in plan timing, not only managers.
Life cycle.
The life cycle is a continuous process, starting from the moment a decision is made to
develop a product and ending at the moment of its complete decommissioning. The
developer needs to know all the stages of the product life cycle, as well as
the tasks and requirements typical for each stage. It will help the developer
to create a high-quality product that will be relevant for a very long time.
These three
key points are closely related. Ignoring one of them may pull the rest of them
into the abyss, and vice versa. However, even a well-mastered system
engineering course will not be productive if a non-tested product with a large
number of bugs is released.
Skill 4 — Basics of software testing
A completed software shouldn't be released without pre-testing. At present, there are 10
methods and kinds of product testing, but the programmer may only master three
of them:
Unit
testing. This type implies testing each individual unit (module, class) for
proper operation. It is relevant and correct to use the TDD methodology
(Test-driven development). In some languages, there are different frameworks
for testing. For example, there are NUnit, Rhino Mocks, etc. in Visual Studio.
Integration
testing. The most difficult type of testing involves testing the
interaction between blocks (modules, classes). This method is time-consuming,
but it will allow you to exclude private incorrect processing of data.
System
testing. This testing method involves the study of an already completed
product. Testing of small projects may be done on your own, but the large and
resource-intensive ones require using automation tools.
Skill 5—Databases
Creating any
software is impossible without implementing a database where all of its data is
stored. It is a group of files that contain records in a template structure. If
it is enough to have a simple database connection system for a regular client the program, then a cloud or client-server application needs a more serious remote
database access scheme.
Understanding
the principles of working with the database and the basics of building connections
in client-server solutions is a promising and extremely essential skill for the
developer, along with knowledge of the security principles, especially if the
programmer plans to work on serious business projects.
Skill 6—Encryption and cryptography
Many
programmers who keep up with modern technologies and cyber-security have
already come across the concept of cryptography or, in other words, data encryption.
Today, two cryptography methods are used:
Private Key.
The method
was relevant even in the time of Julius Caesar when the letters were shifted a
certain number of places down the alphabet. But over time, encryption
technologies became more complicated and eliminated the ability to decrypt a
character set without a specific key. The method is used nowadays, but it is
almost irrelevant.
Public key.
The method
was first invented in 1975, however, it gained the maximum spread and
popularity only in 2009, when the popular Bitcoin cryptocurrency was built on
its basis. Since that time, encryption has been actively introduced into any
software and has undergone many modifications.
Nowadays there are 4 cryptographic primitives in cryptography:
*symmetric-key;
*asymmetric-key;
*hashing;
digital signature.
Each
primitive has its own appliance and usage features. Therefore, if you are
determined to develop business apps, work with personal data, or plan to
transfer voice/text/video messages among individuals or legal entities, be sure
to learn the principles of cryptography. This knowledge will be especially
vital if you plan to use modern technology—Blockchain, on which there are
already many interesting projects.
Skill 7—Blockchain
Blockchain
technology is used to maintain a high level of protection for transactions and
personal data of users, as well as for the reliability of the wallet and the
entire system.
The
principle of blockchain work may be compared to torrent trackers, where the
files or, in our case, the transaction log of the running client is compared to
other clients and replicated to new ones, thus copying the log data to a new
device. All devices (transmitters and receivers) are anonymous spots that do
not transmit any identification data, but only exchange blocks (groups of
facts).
The main
advantage of the blockchain in the modern world is the impossibility of
replacing events that have already occurred. And this is currently the main
advantage of its widespread implementation because it is impossible to deceive
this system. Therefore, if you think about your future and want to be a
sought-after programmer, we advise you to explore this promising technology.
Skill 8—Artificial intelligence
Artificial
intelligence, blockchain, is a rapidly developing technology, and the huge
Artificial intelligence, like blockchain, is a rapidly developing technology,
the huge potential which we will observe in the future. According to the definition given by Andreas Kaplan and Michael Heinlein, artificial
intelligence is a "system's ability to correctly interpret external data, to
learn from such data, and to use this learning to achieve specific goals and
tasks through flexible adaptation."
Globally, Al
mimics the model of human thinking. If the program simply retrieves values from
the database according to certain rules, it is not endowed with Al. If the
system after training creates programs, methods, and documents, solving certain
tasks, it possesses Al.
A developer
who is competent in this sphere will definitely be in demand both today and in
the near future.
Skill 9—Cross-platform software
The cross-platform application allows you to produce a final product, written in a
"universal" form for several operating systems. This is a big benefit
for distributing and increasing the popularity of the software. Virtually all the
development environments for creating projects in high-level programming
languages are cross-platform and easily compile code to different devices
without the need for recompilation.
Thus, you
can double or even triple the customer’s amount of your software. Many people
currently abandon the use of PCs and switch to mobile devices: smartphones,
laptops, and tablets. Therefore, it is important to adapt the developed
software for the maximum number of systems before release. The only
disadvantage here is that a cross-he disadvantage here is that a cross-platform application will never be "perfect" for a specific individual OS.
Skill 10—Operating Systems
That is why
it is essential to not only build cross-platform apps but also to optimize it
further for a specific system, taking into account the interaction
peculiarities. Learn the new features of operating systems, and analyze the way you
can apply them in the completed software in order to improve interaction with a
consumer, improve usability, speed of data processing, etc.
In
conclusion, it should be added that it's not obligatory to possess all the 10
skills listed above. It is better to possess the perfect knowledge in something
than to improve interaction with a consumer, improve usability, speed of data
processing, etc.
In
conclusion, it should be added that it's not obligatory to possess all the 10
skills listed above. It is better to possess the perfect knowledge in something
than to be able to do a bit of everything. Choose what you want to do, that is
interesting for you, set a goal, and stick to it. Do not forget about trends in
your area and new solutions that will improve professional skills and allow the
developer to be in high demand for many years.
I hope the Developer should Acquire the above-mentioned knowledge to develop their own skills.
