Gabriel Angelo — software engineer · saas & automation. I work end to end: database and API design, the interface people actually use, and the integrations in between. Right now I build products at PontoGO, PeopleNity, Homefly and MeuProcesso, and teach full stack development at Digital College.
Software engineer from Brazil, building SaaS platforms, mobile apps and automation for teams that ship on tight deadlines. I work end to end — database and API design, the interface people actually use, and the integrations in between.
Back end, integrations and the employee app
Time and attendance for Brazilian companies: employees clock in from the phone — offline too — request adjustments, attach documents and follow their hour balance in real time.
Product engineering
A portal where lawyers publish case updates once and the client follows everything in one place, instead of answering "any news?" over WhatsApp all day.
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 work on the platform and the integrations around it.
Founder engineer — the whole stack
A platform for Brazilian accounting firms. A Go and PostgreSQL API behind a Next.js front end, talking to government web services: filings and legal notices arrive as work a team can actually track.
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 sense that software is built, not found.
PHP. Forms, databases, and pages that finally did something.
HTML, CSS and JavaScript. The interface stops being a detail and becomes the craft.
First job as a developer — production code, deadlines and code review.
Partner in a startup: building the product and carrying the outcome.
Full stack instructor at Digital College, teaching new cohorts to ship.
SaaS, mobile and automation in production — PontoGO, PeopleNity, Homefly and MeuProcesso.
Where I build
Product work across PontoGO, PeopleNity, Homefly and MeuProcesso: scalable back ends, third-party integrations that are not allowed to fail, and small teams moving fast without breaking what is already in production.
Products in production
Plannea CRM, a platform for Brazilian accounting firms: a Go and PostgreSQL API behind a Next.js front end. It talks to government web services and tax data providers, turning filings and legal notices into work a team can track.
Work that runs itself
WhatsApp integrations, n8n workflows and AI-assisted routines that take manual steps out of back-office operations — document intake, notifications, and data pulled from systems that were never meant to talk to each other.
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. Most of the course material and project starters are public — 86 repositories, from a first login screen to complete APIs.
Open to product work, consulting, and conversations about SaaS architecture, integrations and web performance. Email is the fastest way to reach me — LinkedIn works too.
