About me

I build software people enjoy using. I explain the process in plain language and partner with product teams to turn tricky problems into simple, human-friendly products.

I help deliver great UX, production-ready code, and DevOps that scales with your ambitions. I'm always learning and excited by interesting challenges — if you'd like someone who gets things done without the jargon, let's talk.

How I help teams

From sketch to scale: I connect good architecture with dependable delivery so businesses can move confidently.

Frontends that feel snappy and are easy to maintain (Angular, Vite, Tailwind).
APIs and integrations built for reliability and clarity (Java, .NET, Python).
Repeatable release pipelines and infra-as-code using Kubernetes and Azure DevOps.

Ways of working

Scrum‑savvy full‑stack developer who builds products tailored to your needs. I use practical rhythms where they help, then focus on delivering the right outcomes — not selling process, shipping product.

Product-first delivery: align roadmap and work to measurable outcomes.
Hands-on development across frontend and backend.
Pairing, code reviews, and a quality-first engineering mindset.
