Are you looking for a guide on expert developers?

Software technology is continuously evolving. Software developers often find themselves in a quandary of whether to keep up with various latest development technologies or specialize in just one. This includes programming languages and frameworks. The chosen path either leads to a generalist mobile or web developer or an expert developer.

The global developer population is about to reach 28.7 million by 2024. Not every developer is an expert. So how do you distinguish an expert from a generalist or an intermediate developer? Read on as we explain what expert developers are.

Expert Developers

Expert developers are software engineers with significant experience in software development in several industries. They have specialized skills in a specific technology set gained by working in the software industry for many years.

Apart from programming, expert developers have experience with software design, testing, and maintenance. 

Let’s look at the skills of expert software developers in detail.

Skills of Expert Software Developers

Expert developers possess the following skills, among others:

1. Programming Languages and Tools

An expert software developer can write maintainable and clean code in at least one programming language, and tech stack, and have proficiency in the related platforms and frameworks. 

For example, expert Java developers are familiar with Java platforms, including Java SE (standard edition) and Java EE (enterprise edition), moreover, they have relevant experience with multiple application frameworks, like Spring, Hibernate, Grails, etc., to build web and mobile applications.

2. Software Development Methodologies

Expert developers are familiar with multiple software development methodologies. While a few software applications with fixed specification requirements work well with the waterfall model, most follow the agile development process. 

Expert software developer utilizes multiple agile methodologies, which help them efficiently plan and execute the software development lifecycle.

According to the Scrum Master Trends Report, 81% of users use Scrum with agile practices, like Kanban, Xtreme Programming, etc. 

Expert developers adopt a hybrid software development approach where iteration or sprint-based scrum development helps expert developers break down and prioritize development tasks while ensuring faster time-to-market.

Kanban boards help them incorporate user requirements into the development process while giving complete visibility into the software development process.

3. Software Debugging and Testing

Years of coding make developers experts in code debugging and troubleshooting. They can quickly analyze code and detect bugs. They are able to effectively utilize debuggers that come with IDEs (Integrated development environments).

Software debugging skills help them conduct code review sessions, especially for junior developers.

Software testing is an essential stage of the software development lifecycle, and expert developers contribute significantly here. They are skilled in implementing test cases to ensure each code module or app functionality works accurately separately and together. 

Senior developers help conduct unit testing, integration testing, system testing, etc., along with dedicated app testers.

For this, expert developers are skilled in software testing tools, like Selenium for web applications, Appium for mobile apps, etc., and familiar with the latest testing trends, like automated testing, cloud-based testing, etc.

4. Software Architectures

Expert developers have experience working on multiple software architectures and design patterns. They can design a software app using the most suitable architecture, such as 

  • Service-oriented architecture to build software features as separate services that communicate over a protocol like HTTP;
  • Event-driven architecture for real-time or IoT-based applications where software responds to messages sent by other services;
  • Client-server architecture help design web applications, etc.

Another software design expertise of specialized developers is in design patterns. Software design patterns are solutions to software design problems that developers often encounter.

Expert developers use these design patterns, such as singleton, model-view-controller, layered, etc., to develop scalable, maintainable, and adaptable software.

5. Database Design

Expert developers possess a range of database design and development skills. They are familiar with multiple database design models that fulfill different data requirements.

They are proficient in database modeling techniques, such as entity relationship diagrams, UML diagrams, data flow diagrams, etc.

Expert developers are also well-versed in data organization via normalization techniques to reduce data redundancy, ensure data integrity, and minimize database anomalies.

They are also skilled in database solutions performance tuning using indexes, optimization of database queries, stored procedures, etc., to improve database response time.

Expert software developers are proficient in SQL programming. They can write complex queries, triggers, functions, etc., for database transactions and data manipulation.

They are familiar with SQL and No-SQL database technologies, like Microsoft SQL Server, Oracle, Cassandra, MongoDB, etc.

Data warehousing is another prominent skill of expert developers. They can design and develop data warehouses using techniques like ETL (extract-transform-load), OLAP (online analytical processing), etc.

6. Development and Operations

Expert developers are skilled in development and operations or DevOps practices. These DevOps practices allow them to improve the efficiency of the software development process while adopting a collaborative approach to software development and deployment. 

Expert developers are familiar with DevOps techniques, such as:

  • Continuous integration/continuous delivery by configuring deployment pipelines;
  • Infrastructure-as-a-code, where developers automate the provisioning, configuration, and management of infrastructure resources
  • Containerization, where developers package and deploy containerized applications in production environments to manage workloads.
  • Monitoring and logging to understand and resolve issues in production environments, etc.

7. Software Documentation

Expert developers have experience writing clear and concise documentation that serves various purposes. Software documentation that expert developers are proficient in writing includes the following:

  • Technical documentation is for other developers who will develop or maintain the software in the future. It explains software architecture, design, data structures, etc.;
  • User documentation helps users understand how to operate the software and utilize its features. It includes user guides, tutorials, help documentation, etc.;
  • Code documentation helps other developers understand the working of each code module. It includes comments in the source code;
  • API documentation describes using application user interfaces (APIs) for other developers who use your APIs. It provides information about API parameters, response values, etc.;
  • Design documentation is of various types, like architectural diagrams that illustrate the structure of software systems, flow charts that visually represent the logical flow of software functions, etc.

8. Problem-Solving

Expert developers have a range of problem-solving skills that help them design and develop complex software applications. Some of these skills for experienced developers include the following:

  • Analytical thinking helps developers identify complex problems and devise solutions for them;
  • Creativity helps experienced developers build innovative software solutions;
  • Attention to detail is necessary to examine minute details in software designs, identify tricky and little bugs in app code that could lead to big problems, and write high-quality code.

9. Communication and Collaboration
