Who I Am

I build backend systems where security and data integrity matter — encrypted storage, JWT authentication, and role-based access control. My projects include a paper-protection platform using AES-256 encryption and device fingerprinting, a personal finance tracker with MongoDB aggregation pipelines, and an AI-powered meeting summarizer built on the OpenAI API. I work primarily in Node.js and Express, with MongoDB and MySQL for data, and I'm currently strengthening my foundations in data structures, database design, and system design so I can reason about scale, not just ship features.
