Software engineer building backend and AI-integrated systems — retrieval pipelines, rule-based decision engines, and authenticated APIs — in Python, TypeScript, and Go. Strong CS fundamentals backing hands-on experience from schema design to live deployment. Fits core backend/SDE roles and AI engineering roles alike.

Software Engineer Intern at CRIS – Centre for Railway Information Systems (2025-05 – Present)

• Sole engineer on an end-to-end RAG middleware layer linking live railway data (RFID, dashboards, port-logs) to NL queries.
• Built the pipeline from scratch sans docs, producing 113,000+ schema-validated chunks across 50+ files.
• Designed an LLM reasoning pipeline with zero hardcoded mappings, architected for schema variability across live databases.
• Diagnosed a semantic-search defect excluding key metadata; rebuilt ChromaDB with hybrid dense + lexical retrieval to fix it.
• Authored an independent report linking an IEEE EDGE 2025 paper on blockchain AI integrity to CRIS's own systems.
