I am a performance-focused Full-Stack Engineer with an extensive background in the financial sector (including operations automation at BNP Paribas and infrastructure deployment at Renaissance Investment Management). I specialize in bridging deep financial domain logic with production-grade, highly secure software systems.
- Core Architectural Focus: Real-time data streaming (WebSockets), reactive state management (Advanced RxJS semaphores), enterprise database isolation (PostgreSQL RLS), and lightweight infrastructure containerization.
- Performance Metrics: Achieved up to 6.5x frontend bundle reduction via Brotli/lazy loading and optimized Docker footprint by cutting image sizes from 1.44 GB to 300 MB.
