How I work
I work across backend systems, product engineering, and delivery infrastructure. My experience includes software development in large-scale product environments and regulated financial infrastructure, with a focus on scalable architecture, clean implementation, and dependable delivery.
Alongside that, I ship focused product and integration work—such as applications for Brassco and TTLock-style backend integrations—and personal projects that keep my tooling and craft sharp.
What I bring
- Scalable backend and platform-oriented engineering.
- Clean architecture with a focus on maintainability.
- End-to-end ownership, from design to deployment.
- Experience with cloud-native systems, integrations, and delivery automation.

More about me
Outside of work, I’m a father of two, a lifelong learner, and someone who values steady improvement in both engineering and life. I’m especially interested in software craftsmanship, clear thinking, and building systems that remain useful beyond their first version. More on my path and focus areas on the About page.
