πŸ”§ What I Actually Build

I don't just write code β€” I architect systems. Here's what that looks like in practice:

πŸ–₯️ Backend Systems & APIs β€” Production-ready RESTful APIs with layered MVC architecture, JWT/RBAC auth, rate limiting, and structured error handling. I think in contracts, not just endpoints.

πŸ—„οΈ Database Engineering β€” Schema design from scratch: ER modeling, migrations, query optimization, Redis caching. Designed 15-entity schemas with 31+ relationships and indexing strategies for real performance gains.

πŸ€– AI & RAG Pipelines β€” LLM-powered applications that are actually reliable: semantic chunking, FAISS vector retrieval, grounding validation guardrails, and structured evaluation frameworks. Not prototypes β€” production pipelines.

πŸ₯ Healthcare Data Engineering β€” Software engineering rigor applied to biomedical problems: hospital systems, patient feedback intelligence, ECG signal processing.

⚑ Real-time & Performance β€” Socket.IO messaging/notifications, Redis caching layers, pagination design, and recommendation engines built to scale.
