# Muhit Khan I build software systems for messy real-world operations. Software Engineer and systems architect who designs end-to-end solutions to real-world operational problems, not just features. B.Tech in Computer Science (KIIT University, India) with 2+ years architecting systems where reliability, data integrity, and scale are non-negotiable, leading the data-migration strategy and core module architecture for a nationwide Enterprise ERP at the Bangladesh Ministry of Defence, redesigning relational schemas to sustain 99.9% uptime under high-concurrency load. Independently identified a gap in how high-volume clinics manage patient care, then designed and built Doctors Canvas end-to-end: a cloud system with a local-first data layer (RxDB/RxJS) for unreliable connectivity, plus an integrated AI clinical assistant for history summarization and drug-interaction checks, now used in active practice. Works fluently across the stack (React, Next.js, Node.js, TypeScript, PostgreSQL) and applied AI/ML (LangChain, RAG) as tools in service of one goal: understanding a domain's real constraints, then engineering a system that holds up under them.
