Professional Summary

Full-stack developer engineering web products, automation systems, and CRM integrations. I adopt a technology-agnostic mindset: I first analyze the business model and scalability requirements, then determine the optimal technical stack. I integrate AI agents and LLMs across the full development lifecycle to deliver higher quality software with accelerated timelines. Prior to software engineering, I spent 7+ years managing multi-million dollar logistics across regional renewable energy megaprojects.
