02 What I build
A product, not a demo
I build your product, from idea to launch
I design, code and ship real web & mobile products — solo or with your team. You start with an idea, you leave with a live product.
How we start
- You describe your project 2 minutes, no jargon. Advanced fields if you're technical.
- You receive your blueprint Scope, approach, next steps. No commitment.
- We build together Firm quote, then we build, ship and go live.

03 Workflow
The Product Engineer method
Spec → Plan → AI Blitz → Polish. AI is a multiplier under human supervision, never a substitute.
Spec & Vision
Writing the product vision and design doc. Hardening specs, edge cases, security and UX frustrations before a single line of code.
Tech Plan
An implementation plan broken into numbered, sequential tasks. Architecture is settled up front to frame how the agents execute.
AI Blitz
Parallel delegation to AI agents via an orchestration workflow. The feature is delivered atomically and full-vertical (from DB to UI and i18n).
Polish & Review
Demanding, Tech-Lead-grade review. Fast deployment to main, thorough production testing, rapid fixes with an immediate feedback loop.
