At Data-Driven-Lab, I delivered detailed commission reports with per-transaction statistics, including NestJS endpoints for transaction aggregation. The work increased CSAT by 7% and cut commission-related support queries by 10.4%.
I added PWA support, built installation-promoting UI components, and set up GTM analytics tracking, reaching a 12.1% adoption rate. I also resolved legacy dependency conflicts in the Nx monorepo and migrated components to Angular 17+ control flow, reducing bundle size by 32%.
At Simbirsoft, I delivered an educational module from PostgreSQL schema and NestJS REST API through React UI; it became the template for three later EdTech features. I’ve also worked on CI/CD and automated AWS deployments, Angular migrations, and reusable dashboard charting.
