What I'm looking for

I want to build backend/cloud systems where I can improve performance, design resilient event-driven architectures, and ship with strong CI/CD. I’m energized by microservices, clean design (DDD/Clean Architecture), and measurable impact.

I’m a backend-focused software developer who builds reliable, high-performance systems with .NET, event-driven messaging, and cloud infrastructure. In recent work, I slashed critical API latency from 5s to 65ms and reduced page loads from 60s to 0.5s by optimizing bottlenecks and memory leaks, while migrating to TypeScript/Zustand.

I enjoy designing resilient architectures—building an AI-driven webhook pipeline for automated ingestion and enforcing zero-message-loss reliability with message brokers and Dead-Letter Exchanges. I’ve also modernized authentication by replacing fragile Node.js auth with Supabase Auth and a .NET YARP gateway, and I deliver automation through high-throughput .NET scheduling microservices using AWS SES.
