Hi, I‘m Gabão
I‘m a frontend-focused full-stack developer specializing in React, React Native and TypeScript, with backend experience in Node.js, NestJS, Vue and Python. Most of my work is in fintech — and I‘m open to remote contract roles with US & EU companies.
About
I started my journey in technology in 2018, during my Computer Science Bachelor's at Universidade Regional Integrada do Alto Uruguai e das Missões (URI). My first role was at Platform Builders, working on the front end of a digital-bank mobile app, where experienced developers taught me a lot about web and mobile development. Today I'm a frontend-focused full-stack developer working mainly in fintech — currently as a frontend developer at Finaya, building white-label apps for financial and credit products, alongside full-stack work at SAN Internet.
Services
I specialize in React, React Native and TypeScript, with solid backend experience in Node.js, NestJS, Vue and Python — which lets me deliver across the back-end, web and mobile.
Mobile
Great platforms usually count with a mobile app for their users, as it delivers several benefits to the business.
Web
A strong presence on the Web is also important to your business, making it more professional and delivering trust and security to your clients.
Back-end
And finally, to give life to all those screens, flows and interactions, both data and logic are needed — that's where the back-end comes in.
Experience & impact
A few highlights from my work: I raised a company's public rating from 3.7 to 4.3 in about three months with a client-review strategy, and improved customer satisfaction by ~16.22% by centralizing logging with Graylog. I'm also co-author of a peer-reviewed book chapter (Atena Editora, 2025) on a hardware/software architecture for solar-plant data acquisition, where I built the Node.js/Express backend (served with Nginx), the database integration and the React dashboard.
60,000+ users
Shipped a white-label React Native app (iOS & Android) reaching a combined 60,000+ users across multiple fintech clients.
White-label architecture
Designed a per-client white-label customization architecture on a single shared codebase, so each client can heavily customize their app without affecting the others.
Payments
Integrated PIX and Bitcoin Lightning as payment methods, working across financial and credit products.
Portfolio
Below it‘s possible to see and understand which contexts and technologies I have already worked on and you can also see if any of them match your particular needs, or even the industry that you actuate.
