What I offer

Services

Six areas where I deliver consistent, predictable results. Scoped to your needs, without agency overhead.

1

Web Development

Custom websites, landing pages, and web applications built with modern frameworks. I write clean, maintainable code that loads fast, works everywhere, and is easy to update as your business grows.

Process Automation

From mapping your workflows to identify automation opportunities, to building the systems that implement them. API integrations, custom scripts, and modern tooling that cuts manual effort and surfaces useful insights — without disrupting what already works.

Web-based and cross-platform applications using React Native and Expo. One codebase, iOS and Android. I prioritize performance, UX, and experiences that work reliably — online and off.

Consulting

Architecture reviews, technology selection, and strategic advisory. If you're about to make a technical decision that matters — choosing a stack, redesigning a system, evaluating a vendor — I help you think it through before you commit.

Testing & QA
