About Me
Most ML projects fail after the model works. The hard part isn’t accuracy, it’s making the system reliable enough to ship. That’s the problem I care about: building AI that holds up in production, not just in notebooks.
I’m an AI/ML Engineer and recent Master’s graduate from Illinois Institute of Technology, Chicago. At InsOps, I architected a 3-path LangGraph orchestrator routing insurance queries across 7 execution modes using a 27-case routing matrix, reducing routing latency from a 5.9s sequential guardrail baseline to under 1.3s with async probes. I also built the full retrieval layer: a 5-stage RAG pipeline with BGE-large embeddings, BM25/vector hybrid search, RRF fusion, GPU-based cross-encoder reranking, pgvector storage, and Langfuse end-to-end observability.
As a Data Science Intern at Pure Platform, I built a multimodal text-image search engine achieving 92% top-k retrieval accuracy and 25% better relevance. I also validated FAISS IndexHNSW search with FastAPI integration, achieving 20% faster retrieval and 2× concurrent searches without added infrastructure costs.
My independent GenAI work includes an Autonomous CI Failure Fixer with 9 agents, a 12-agent multi-agent orchestration system with specialized tool use, and a Terraform-based LLMOps platform with evaluation-gated canary deployments, automated rollback, and GitHub Actions CI/CD on AWS ECS. I’m open to AI Engineering, ML Engineering, GenAI Engineering, and Applied AI roles.
