What I do

I design, build, and ship complete SaaS products solo — from the first wireframe through backend, frontend, payments, infrastructure, and the SEO that brings in traffic. Twenty years on the Laravel/PHP stack, with deep specialization in multi-tenant SaaS, programmatic SEO at scale, and practical AI integration. You bring the business outcome; I deliver a deployed, documented, maintainable product — no team required. I also build with AI day to day — shipping Gemini-powered product features and using AI throughout my own workflow to move from idea to production faster without cutting corners.

Engagements I take on: building and launching SaaS products · programmatic SEO and organic growth · AI feature integration · custom admin panels and internal tools · project rescue and scaling · fractional / part-time senior engineering.
