Available for Projects

I have designed and developed almost every kind of software connected to the internet. With over 20 years of experience across web, apps, prototypes, internet services, branding, commerce, and utilities, I communicate clearly across design, development, and business model decisions.

Currently working as CTO and CPO at an AR content and solution startup.

Become a partner

Web agencies and designers

I focus on translating design intent and detail accurately. Send the design deliverables, and I can handle frontend, backend, deployment, and server operations end to end.

Startups

You do not need to be an IT expert to test whether an idea is creative, realistic, and efficient as a path to revenue. Working with a developer who understands product decisions can reduce cost and time while improving launch quality.

Enterprises and small businesses

If your company needs a website or app but software is not the center of the business, outsourcing is often the right move. A full-stack developer creates strong efficiency for small and mid-sized projects.

Developers

If you are preparing something fun and meaningful, I am open to building together. Extra welcome if you care deeply about variable and file names.
