How I build
Tools and approach
Ruby on Rails
Web applications. Fast to build, reliable to run, easy to maintain over time.
Flutter
iOS and Android from one codebase. Native feel, single source of truth.
Maintenance
Keeping products healthy — updates, bug fixes, and incremental improvements.
Design
Good design sense, designer friends when I need them.
AI Agents & Tools
I use AI to help with building, design, and marketing. My main IDE is Cursor.
About
I'm a product engineer. I care that what we build actually works, ships, and stays maintainable — not just features in a backlog.
Focused · Honest · Product-led
One client
Not an agency. One focused partnership.
Own products
Building and shipping my own software on the side.
Transparent
Clear about the stack and how I work. No black box.
Small by design
Just me. Designer friends when needed. AI tools for the rest.
