What I'm looking for

I seek roles where I can build production-grade AI/ML systems, lead backend and MLOps efforts, work with LLMs, and drive measurable business impact in collaborative teams.

I am an AI/Machine Learning Engineer and backend developer with 6+ years of experience delivering AI/ML solutions and building scalable backend systems across fintech, SaaS, and generative AI platforms.

I architect end-to-end AI solutions, design secure high-performance Python backends (FastAPI/Flask), and deploy models and services on cloud platforms like GCP and AWS with CI/CD, containerization, and monitoring.

I have built and deployed LLM and LMM pipelines (RAG, LangChain, Hugging Face), integrated vector databases and semantic search (Pinecone, Qdrant), and implemented robust evaluation, human-in-the-loop validation, and safety guardrails for production reliability.

Across consulting, startups, and research projects I have improved time-to-insight, automated workflows, and driven measurable outcomes—reducing research time, increasing engagement, and delivering production-ready AI systems.
