Product development for founders

From product direction
to working code.

I help founders and startups build software products across mobile, web, and AI — covering strategy, prototyping, design, and hands-on development.

From discovery to delivery

I cover the full product lifecycle: helping you figure out what to build, designing how it should work, and writing the code that ships it.

Mobile Apps

Native-quality iOS and Android apps using React Native. I handle everything from architecture to App Store deployment and backend integration.

Web Applications

Modern web apps with React, Vue, or Next.js. Real-time features, API design, progressive enhancement, and production-grade DevOps.

AI Integration

Practical AI that solves real problems: custom agents, LLM-powered features, natural language interfaces, and recommendation systems.

Technical Consulting

Architecture reviews, code audits, and honest assessments. I help teams unblock stalled projects and make better technology decisions.

Product Development

Strategy, roadmapping, prototyping, and launch planning. I bring a product mindset to every engagement — not just engineering.

Prototype Reviews

Expert review of your prototype's architecture, scalability, and production readiness. Actionable advice on what to fix before you scale.

Product leadership meets hands-on engineering

I help founders and startups go from idea to working product — covering strategy, design, and technical delivery.

Over 17 years I've led engineering and product teams at Microsoft, SwiftKey, and Glovo, building and scaling products from zero to millions of users. I've held product leadership roles at venture-backed startups, and I bring that same rigour to every engagement.

If you're figuring out what to build, or need help building it properly, let's talk.

your project.

Whether you have a clear brief or just an idea, I'd love to hear about it.
