I’m a Full Stack Engineer with 2 years of experience building scalable Python and React.js applications and AI-driven automation. I’ve developed a project management platform supporting 1,200+ concurrent users by optimizing FastAPI backend services and database design, including indexing strategies, and I implemented role-based access control (Owner, Manager, Member) through secure Python RESTful APIs.

I also focus on practical AI that delivers measurable outcomes: I built a GPT-4 + LangChain project assistant to automate task allocation, progress summaries, and deadline reminders, reducing manual coordination by 30%+. Across projects, I’ve improved performance with clean, modular architecture and responsive UI work in React and Tailwind, and I delivered an AI-driven email-to-ticket automation system using Microsoft Graph, RAG, and confidence-based routing that reduced manual triage by 50%+ while maintaining reliability at high volume.
