Gabriel Angelo, software engineer · saas, automation & ai. I work end to end: database and API architecture, the interface people actually rely on, and the integrations between them. I currently build products at PontoGO, PeopleNity, Homefly and MeuProcesso, and teach full-stack development at Digital College.
Brazilian software engineer specializing in SaaS platforms, mobile applications and automation for teams delivering under tight deadlines. I work end to end — database and API architecture, the interface people actually rely on, and the integrations between them.
Back end, integrations and the employee app
Time and attendance for Brazilian companies: employees clock in from their phones, including offline, request adjustments, attach supporting documents and monitor their hour balance in real time.
Product engineering
A portal where lawyers publish case updates once and clients track everything in a single place, eliminating constant WhatsApp follow-ups for case status.
Micro-services and white-label infrastructure
gRPC between internal services, REST at the edge, and one deploy that serves several brands from the same codebase.
Product engineering
Product engineering on the platform and its surrounding integrations.
Founder engineer — the whole stack
A platform for Brazilian accounting firms: a Go and PostgreSQL API behind a Next.js front end, integrated with government web services to turn filings and legal notices into trackable work for the team.
Founder engineer — the whole platform
A multi-tenant SaaS for course platforms, developed after an off-the-shelf solution no longer met my requirements. Go microservices behind a single gateway — catalog, enrollments, media and notifications — with Next.js applications for the student area and the course administration panel, video transcoding and signed playback through Mux, and identity management via Zitadel. It currently powers Devfly, my own programming course.
Solo project
A running app in React Native and Expo: background GPS, route drawing, pace and elevation splits, offline-first storage, and points, levels and achievements on top.
Java. Algorithms, objects, and the first real understanding that software is built, not found.
PHP. Forms, databases, and the first pages that performed real functions.
HTML, CSS and JavaScript. The interface stops being a detail and becomes the craft.
Production code, deadlines and code review from day one.
Co-founder of a startup, responsible for building the product and owning its outcomes.
Full-stack instructor at Digital College, training new cohorts to deliver production-ready software.
After PontoGO (Nov. 2022 – 2026), joined RT Data Consultoria as a Full Stack Developer.
Full Stack Developer at RT Data Consultoria, and founder of Vertexa, the platform behind my own course, Devfly.
Where I build
Three years as part of PontoGO's core engineering team, alongside product work on PeopleNity, Homefly and MeuProcesso: scalable back ends and third-party integrations with zero tolerance for failure. Currently a Full Stack Developer at RT Data Consultoria.
Products in production
Plannea CRM, a platform for Brazilian accounting firms: a Go and PostgreSQL API behind a Next.js front end, integrated with government web services and tax data providers to turn filings and legal notices into trackable work for the team.
Work that runs itself
WhatsApp integrations, n8n workflows and AI-assisted routines that eliminate manual steps from back-office operations — document intake, notifications, and data retrieved from systems with no native integration between them.
React Native
Lepus, a running app built with React Native and Expo: background GPS tracking, route drawing, pace and elevation splits, offline-first storage, and a points system with levels, goals and achievements.
Passing it on
Instructor at Digital College, teaching full-stack development to new cohorts, and founder of Devfly, my own programming course. Most of the course material and starter projects are public — 86 repositories, from a first login screen to complete APIs.
Open to product engineering roles, consulting engagements, and conversations about SaaS architecture, integrations and web performance. Email is the fastest way to reach me; LinkedIn is also available.
