Freelance fullstack developer.
I'm a freelance full-stack developer focused on building products that are fast, clear, and well-made. I work across the web and mobile stack — Next.js, React Native, Astro, Cloudflare — and integrate AI tools across most of what I build. I care about the details.

Henry Coach Pilates
Henry Coach Pilates is an online pilates studio run by Henry Mesa. I designed and built the entire website over three months, working closely with Henry to create a striking yet simple user experience. Built with Next.js, Tailwind CSS, and Cloudflare, with payment processing handled by Stripe.
VisitÆpoch
Æpoch is building a new kind of currency — one grounded in the simple fact of a human, alive and present, on a given day. I contract with Æpoch on their web platform, contributing to the infrastructure and interfaces that bring this vision to life.
VisitThe Money Game
The Money Game is an 80s retro-game themed financial education experience that teaches people about money, bitcoin, and the value of time. The site is heavily influenced by its owner, Francisco Quadrio Monteiro — a Portuguese financial advisor and bitcoiner. Built with Next.js, Tailwind CSS, and Clerk.

VisitCreative European Adventures
Creative European Adventures brings pickleball enthusiasts from America to Portugal for a one-of-a-kind trip — world-class courts, exceptional local cuisine, and some of the finest hotels the country has to offer. I designed and built the website to clearly communicate the experience and make it easy for visitors to get in touch.
VisitWinged Ones
Winged Ones is an e-commerce store offering authentic Native American ornaments. I built the site with a focus on respectful presentation of the pieces and a clear, straightforward purchasing experience.
VisitAbout
I'm a freelance full-stack developer who builds real products for real clients — web platforms, mobile apps, smart contracts, and everything in between. My work spans Next.js, React Native, Android, Node.js, Solidity, and Cloudflare, and I've shipped everything from pilates studios to human-centric financial protocols.
I work with AI tools across every project I build. It has changed what I can deliver, how fast I can move, and how I approach problems I haven't seen before. I'm not just a user of these tools — I think carefully about how they fit into the products I'm making and the workflows of the people I'm building for.
I'm drawn to technology that is grounded in something real. One of the projects I'm most engaged by is my work with Æpoch — a company building a currency that rests on the simple fact of a human being alive and present on a given day. That intersection of technology and human value is where I find myself most interested.
