About Theo

Freelance web & mobile developer, I design and deliver complete products, from a conversion-focused showcase website to a mobile app published on the stores.

My playground: React, Next.js, and Capacitor. I am comfortable across the entire stack, from front-end to back-end (Node.js, SQL, API), including deployment.

My flagship project, EliteForm, is a fitness & nutrition application that I designed from A to Z: custom workout program generation engine, meal plans, subscription system (RevenueCat), and publication on the App Store and Google Play. This is what sets me apart: I don't just code a page, I know how to take a product all the way.

By working with me, you have a single, autonomous point of contact who respects deadlines and speaks your business language, not jargon. Available for remote work and responsive: shall we schedule an initial discussion to define your needs?
