I’m a software engineer building secure, production-grade backends and AI-powered infrastructure. I’ve been architecting systems end-to-end—from data modeling and API design to observability and deployment—so they stay fast and dependable under real traffic.

In my freelance work, I architected a secure e-commerce marketplace using Django and Next.js, using Redis for session caching to reduce DB load. I optimized PostgreSQL performance through query plan analysis and indexing, resolved N+1 query issues, and added a pytest suite with structured logging and request tracing for production-grade API observability.

I also contribute to a massive distributed messaging platform, patching server-side bugs in a high-concurrency Python environment and fixing cross-platform authentication issues by enforcing consistent data constraints. My projects reflect how I like to engineer: OCR/NLP pipelines for healthcare data extraction, a GPU-accelerated key-value store designed to bypass the Python GIL, and a rootless container runtime using Linux namespaces, cgroups, and OverlayFS.
