What I do

Services

Full-stack product delivery for modern teams

Discovery to Delivery

I take products from discovery to production—greenfield or existing. I ramp up fast on context and own execution end-to-end across UI, backend, and infrastructure.

AI-Powered Development

I use MCP integrations, Claude, and AI-native IDEs daily to ship faster—delivering with the velocity of a team, not just one engineer.

Full-Stack Engineering

From React/Next.js frontends to Node.js APIs, PostgreSQL, and cloud infrastructure (AWS, Azure, GCP). One person, full ownership.

About me

Engineering, end to end

I take products from discovery to production—starting greenfield projects, picking up and evolving existing codebases, and leading the technical work. I'm equally strong across frontend, backend, and cloud (with CI/CD on Azure and AWS), and I embed fast with product and business teams. AI tooling—MCP integrations, Claude, Cursor—multiplies my velocity so I ship what would normally require a larger team.

Integrate into new teams and codebases fast—delivering value from week one.
Ship end-to-end across UI, backend, and infrastructure using AI-powered workflows.
Bridge product, engineering, and business stakeholders to keep delivery aligned with outcomes.
