I build the product and the team behind it.
Hands-on engineering leader with a design background. I assemble and lead technical teams, write the hard code, put AI into production, and help founders turn an idea into a working business.
Things I’m building for myself
Independent products give me room to explore ideas, make design decisions, and take responsibility for the complete experience.
In development
Feelix
A personal project I’m actively developing.
The whole product needs an owner.
I take responsibility across engineering, people, design, and delivery.
- Build the team
- I assemble the team and keep engineering, design, and product connected.
- Lead the delivery
- I turn a brief into a plan and stay accountable through release.
- Go deep in the code
- Architecture to implementation. Migrations, integrations, the hard systems.
- Put AI to work
- AI in the product and in how the team ships.
- Design the product
- Flows, interfaces, the feel of it. I can design it and build it.
- Help founders ship
- First version, architecture, into people’s hands. Then the team around it.
