Position: Team Lead / JS Developer
Category: JavaScript
English level: fluent
Years of experience: 5

Achievements worth noting from experience:
- Full rewrite & redesign of legacy frontend platform using Typescript, React & Redux - legacy code was 95% written in javascript, without appearent data flows and hard-to-understand structure. To address this, I've decomposed old code to most basic logical components and story-based data flow chains and recomposed back into scalable typescript application based on our roadmap and expectations. Work was completed in less than 1 month without interrupting our release cycle
- Created cross-platform desktop app POC using Electron from legacy C# code - previous version of the desktop app was written in C# / Objective C, contained a lot of deprecated logic and was not maintained activelly anymore. Even though Electron and JS is known to be slower than other languages for desktop applications, we were able to achieve much better performance by dropping deprecated parts of the app, optimizing logic done in the background and tailoring it to meet latest requirements. Some operations that were not possible to be implemented within Electron / JS was done using native modules per operating system to optimize the performance.
