What I'm looking for

I seek a Tech Lead role leveraging AI/ML and full-stack architecture to build scalable, low-latency systems, mentor teams, and deliver enterprise impact.

I am a Tech Lead and AI/ML Systems Architect with 5+ years designing and delivering scalable, high-performance cloud-native applications across fintech, healthcare, and edtech. I have built production-grade AI/ML systems using OpenAI API, GPT-4 integration, multi-agent orchestration, ChromaDB, and real-time architectures that support thousands of concurrent users.

I have led distributed teams of 10+ developers, owned full SDLC delivery, and optimized systems for low latency and high throughput (5000+ req/sec, 20K+ concurrent users). My work includes architecting Agentic AI, real-time trading infrastructure, HIPAA-compliant healthcare platforms, and CI/CD pipelines that improved deployment efficiency and uptime.
