What I'm looking for

I'm looking to build impactful full-stack and AI products, owning work from design through deployment while growing with strong engineering teams.

I've architected and shipped six production-grade full-stack applications as an independent software developer, spanning e-commerce, enterprise HRMS, content platforms, and AI agent systems. My work includes Lexora, a RAG document Q&A system processing 10K+ chunks with sub-second queries, and SparkGPT, a LangGraph-powered ReAct agent with multi-tool reasoning.

I build APIs and user experiences with FastAPI, React, PostgreSQL, Redis, and Docker, while implementing JWT authentication, RBAC, Stripe payments, CI/CD, monitoring, and test coverage. I also fine-tuned a ResNet-50 medical image classifier to 94% accuracy and optimized inference from 45ms to 18ms with ONNX quantization.
