Serge L.

Stack:

• React,
• React Native.

Responsibilities:

• Developing a client app for the main product of the company (a social network) in React Native remotely;
• Implementing new functionality, suggesting best solutions for others, optimizing performance, debugging and fixing bugs and regressions, refactoring disorganized places in a codebase;
• Taking architecture decisions on what libraries to use and how to implement new functionality and improve existing so it fits the best way into a codebase;
• Thoroughly reviewing merge requests made by colleagues to assure code quality and prevent the introduction of bugs and regressions;
• - Eliminated code monopoly by explaining decisions made in my MRs to colleagues and fully understanding theirs in their MRs;
• Fine-tuning workflow (integrated good code review practices; mentoring middle- and junior-colleagues, enabling them to develop good coding and git practices; introducing a semi-linear history to the repos, which made master branch to be reliably working after each merge and allowed to find the root causes of several regressions using git bisect several times, teaching colleagues performing this task on one's own);
• Introduced Е2Е-tests and then implemented a system, allowing to catch regressions at the early stage, before making successive releases to the public;
• Maintaining and improving CI/CD (writing scripts in Bash and Ruby; developed a caching system for speeding up pipelines in general, implemented caching of built Pods of the iOS version of the app, which was the bottleneck in the pipelines, allowing to reduce overall building time from about 23 minutes to 16);
• Paying tech debts (including those of high complexity which have grown into many parts of the app), refactoring and improving a codebase for easier maintainability in the future;
• As a technical specialist interviewing job seekers for open vacancies.

Stack:

• Developing a client-side of another internal web application in React + Redux;
• Participated in decomposing a whole new project into small tasks with subsequent estimation of their complexity and time required to implement them.

Stack:

• Angular,
• Node.js,
• Express.

Responsibilities:

• Developing a CRM system for automation of business processes remotely. Programming client-side in Angular;
