What I'm looking for

I seek roles leading end-to-end AI and software projects with cross-functional teams, focusing on production ML, observability, scalable infrastructure, and measurable business impact.

I am a software and AI engineer with 10 years of experience designing, building, and debugging agentic workflows, internal AI tools, and backend services. I focus on practical guardrails and reliable infrastructure that enable safe, scalable AI deployments.

I've improved LLM model performance, built multi-agent integration systems with LangGraph and LangChain, and implemented RAG and ETL optimizations that delivered measurable gains. I also reduced infrastructure costs via Airflow migrations and led VoIP and CRM integrations that improved operational efficiency.

My work spans full-stack engineering, ML observability, and production model monitoring using tools like Arize AI and Vertex AI; I have driven speed, engagement, and reliability improvements in legacy and modern systems. I contribute to tech communities and open-source, sharing knowledge through GitHub Education and public projects.

I seek opportunities to lead end-to-end AI and software projects where I can apply my expertise in ML systems, observability, and production engineering to deliver measurable business impact and mentor cross-functional teams.
