I work where product engineering meets systems thinking.
I’m a product-minded engineer with 4+ years of experience building and improving software used by more than 100,000 people. I enjoy the messy middle: translating business complexity into interfaces people understand and systems teams can operate.
My best work happens with founders and product teams who value thoughtful decisions, direct communication and quality that continues after launch.

How I work
Momentum without chaos.
A lightweight, transparent process designed to reduce risk and keep delivery moving.
Discover
A focused call and written brief to align the business outcome, users, constraints and definition of done.
Design the system
I map the product flow, data model, technical boundaries and delivery plan before expensive implementation begins.
Build in the open
Weekly demos, small production-quality increments and written decisions—so there are no end-of-project surprises.
Launch & support
Testing, observability, deployment, documentation and a clean handover with optional ongoing support.
Ways to work together
Choose the support you need.
Every engagement is scoped around outcomes, not a generic bucket of development hours.
Project build
Best for a defined product, feature or modernization initiative.
