AI/LLM Engineer & Backend Architect | RAG, Multi-Agent Systems, Node.j
Ghaziabad, India - 11:43 am local time
I build AI systems that hold up in production — and the backends that make them fast.

Recent work:
- Multi-agent GPT orchestration platform (Fastify + ChromaDB + WebSockets): 40% latency reduction, 5K+ concurrent AI conversations
- Real-time trading infrastructure: 5000+ API req/sec, 20K+ concurrent users, sub-200ms latency
- GPT-4 medical content engine: 60% productivity improvement for healthcare professionals
- HIPAA-compliant healthcare imaging platform for a US client
- 99.9% uptime and 65% faster deployments via CI/CD (GitHub Actions, Docker, AWS ECS)

Six years as a full-stack engineer and Tech Lead, leading teams of 10 across fintech, healthcare, edtech and trading.

Where I add the most value:
→ RAG pipelines and vector search that return the right answer, not a plausible one
→ Multi-agent / tool-calling LLM systems with real evaluation loops
→ High-concurrency Node.js: WebSockets, Redis, RabbitMQ, queueing, caching
→ Full-stack product builds: Next.js, Nest.js, Fastify, PostgreSQL, MongoDB, AWS

I work part-time (~15 hrs/week) on contract engagements and communicate in clear updates, not silence. If you need someone who has already shipped this at scale, message me with what you're building.
