PROFILE
Alexis Kochetov
Over a two-month period, contributed to Actual-Chat/actual-chat by delivering two robust features focused on backend concurrency and cross-browser audio recording. Addressed data integrity challenges by introducing PostgreSQL advisory locks and refactoring the data access layer in C# with Entity Framework Core, ensuring reliable cross-service operations. Subsequently, improved browser compatibility by implementing manual audio resampling and refactoring audio processing using JavaScript and the Web Audio API, with particular attention to Firefox’s recording pipeline. Hardened AudioWorklets to enhance reliability across browsers. The work demonstrated depth in backend development, concurrency control, and advanced audio processing, resulting in more resilient application infrastructure.
