Summary
Nearly three years of industry experience building clean and scalable systems. I evolved from full-stack engineering into designing applied AI solutions and workflow automations: multi-agent systems, RAG pipelines, tool calling and context control. I bring product sense to build systems that drive business value, plus experience leading technical courses and workshops. NASA Space Apps 2024 national winner.
