What I'm looking for

I’m seeking a full-time role in AI/ML Engineering, Applied AI, or SDE, remote or on-site in Bengaluru.

At Easehawk Technologies, I own the AI architecture, prompt design, and production deployment across five live SaaS products. I built a LangGraph email-generation workflow that cut LLM API costs by 90%+ for campaigns of up to 100K leads.

I also built LangChain–Qdrant RAG to ground personalized emails in user documents and web pages; evaluation recorded 0% URL hallucinations. For incoming replies, I combined LLM analysis with deterministic rules, and lead classification recorded 100% accuracy in evaluation.

In my Evoke research project, I reduced measured confident fabrication from 15.3% to 2.0% with schema-conditioned RAG and an epistemic-humility gate. I’m seeking full-time roles in AI/ML Engineering, Applied AI, or SDE, remote or on-site in Bengaluru.
