About

I build backend systems, distributed infrastructure, and AI/ML pipelines.

In production, I've owned and optimized core services for a live e-commerce platform — cut p95 API latency by 90% and shipped Dockerized CI/CD from zero. At Georgia Tech (MSCS, 4.0 GPA), I built a concurrent file server in C and a distributed file system in C++14/gRPC.

Right now I'm deep in Context Engineering and building AI agents. I design systems where LLMs work reliably at scale.

Projects

Multithreaded File Server & Client

Concurrent file server in C that handles parallel client requests under load. Thread-pool with back-pressure control, hardened TCP/IP parsing, and full memory/concurrency validation via GDB and Valgrind.

Distributed File System

Multi-client file system in C++14 supporting concurrent store, fetch, and delete over gRPC. Features write-lock coordination and a self-syncing cache layer that detects local file changes automatically.
