What I'm looking for

I seek hands-on engineering roles building scalable APIs and AI-driven products in collaborative, product-focused teams that value autonomy, technical excellence, and measurable impact.

I am a Senior Software Engineer and entrepreneurial technologist with deep experience building scalable REST APIs, dynamic customer-facing interfaces, and AI-driven automation using Go, JavaScript, Python, React, and cloud platforms. I have led product discovery, client engagements, and delivered solutions across aerospace, Medicare administration, and legal domains, producing measurable time savings and horizontally scalable data pipelines.

I combine hands-on engineering (backend, frontend, DevOps) with technical communication and teaching experience, having authored courses and earned top student evaluations. I co-founded and built production systems on AWS, implemented ML automation, and served as an AI patent examiner—bringing a pragmatic, product-first approach to solving complex technical and operational problems.
