What I do.

One engineer, end-to-end ownership — so you ship faster without stitching together a team.

Full-stack product builds

From empty repo to shipped product — Next.js, Python and .NET, clean APIs, auth, payments. I take MVPs to paying users.

AI & automation

LLM agents, RAG, and workflow automation (n8n, custom pipelines) that remove manual work and add real product value.

GRC & SOC2 automation

Compliance-ready engineering: evidence collection, control mapping, and the automation that gets startups audit-ready.

Cloud & reliability

Production systems on AWS, GCP and Azure — containerized, observable, and built to stay up as you grow.
