πŸ‘¨β€πŸ’» About Me

I am a software developer focused on building reliable web systems and low-level software. I bridge modern full-stack development with systems-level understanding, prioritizing correctness, performance, and clear architecture over unnecessary complexity.

  • Experience: Backend, full-stack, and systems-oriented projects. I work with databases, APIs, MCP-style backends, and AI systems. Focus: Designing backend APIs and services with attention to performance, data modeling, and scalability.
  • Currently exploring: Advanced ML, Data Analysis with R, and System Design.
  • Goal: Seeking roles that demand rigorous engineering standards and complex problem-solving.

🧰 Tech Stack & Tools

  • LLM Hallucination Analysis / RAG Evaluation System
    Designed a controlled evaluation pipeline comparing direct prompting vs RAG across 500+ queries. Implemented dense, BM25, and hybrid retrieval strategies. Achieved 27% reduction in hallucination rate. (Python, RAG, FAISS/Chroma, BM25, LLM APIs)

  • AI Tooling & MCP Server Suite
    Developed a suite of Model Context Protocol (MCP) servers enabling AI interaction with external systems (GitHub, Reddit, personal finance data, predictive ML models). Built reusable MCP infrastructure to support structured, tool-based AI reasoning. (Node.js, Python, PostgreSQL, MCP, REST APIs)

  • HackClub Recruitment Portal
    Led end-to-end development of a production recruitment platform handling 800–1000+ applicants per cycle. Reduced recruitment processing time by ~70% while maintaining 99.9% uptime. (Next.js, TypeScript, Supabase, PostgreSQL, RBAC)
