About

I build software where AI meets messy, real-world enterprise systems and I've spent ~5.9 years getting good at the "messy" part. I'm a Senior Software Engineer at OneOrigin (EdTech), where I lead integration and platform work across Ellucian (Banner, Recruit, Colleague), Salesforce, Anthology, and LeadSquared. Recently I led the zero-downtime migration of 15 institutional clients onto a re-architected microservices platform, built an event-driven transcript-processing pipeline on AWS SQS with exactly-once delivery, and shipped an AI extraction layer (Google Document AI + Gemini) that turned days of manual work into minutes. I also mentor a 7-person cross-functional team. My core stack is TypeScript end to end React/Next.js on the front, Node.js/Fastify/NestJS on the back and AWS, with PostgreSQL, MongoDB, Redis, and Elasticsearch, plus event-driven architecture via SQS/EventBridge/RabbitMQ. Lately I've gone deep on AI engineering: RAG systems, LLM orchestration, MCP, and Document-AI pipelines. Outside work, I'm a compulsive builder. I ship side projects to learn in public a production RAG knowledge base over enterprise integration data, a deployed personal AI assistant, a personal-accountability app, and an open-source Chrome extension — and I document the journey at @tanmaygandhi.builds. I'm at my best on teams solving hard problems at the intersection of AI and integration-heavy systems. Always open to a good conversation here or at tanmaygandhi2901@gmail.com
