What I'm looking for

I seek a hands‑on technical role building AI automation and cloud‑native products, mentoring teams, and delivering measurable operational impact.

I am a senior full‑stack software engineer and automation & AI systems architect with 13 years of experience building scalable web apps across SaaS, e‑commerce, and energy analytics. I design and deploy production‑grade conversational AI platforms and complex cloud‑native automation workflows that reduce manual work and unlock business value.

I've led cross‑functional teams, mentored junior developers, and driven company‑wide AI adoption, architecting systems using Next.js, React, Supabase, Python/FastAPI, n8n, ElevenLabs, and GCP. Key achievements include deploying a full‑stack conversational AI platform, an 80‑node AI interview workflow, and a scalable speaker diarization API handling large audio files.

I enjoy building maintainable, testable, high‑performance code and practical AI integrations that improve operations and product experiences. I seek roles where I can lead technical execution, mentor engineers, and deliver measurable automation and product impact.
