I build

Gabriel Angelosoftware 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.

Who am I?

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.

  • Go and PostgreSQL back ends behind Next.js front ends, in production.
  • Mobile with React Native and Expo, offline-first when it has to be.
  • Automation and integrations that take manual steps out of the day.

The road so far

  1. 2012

    First lines of code

    Java. Algorithms, objects, and the first real sense that software is built, not found.

  2. 2015

    The web calls

    PHP. Forms, databases, and pages that finally did something.

  3. 2020

    Front end for real

    HTML, CSS and JavaScript. The interface stops being a detail and becomes the craft.

  4. 2021

    Paid to code

    First job as a developer — production code, deadlines and code review.

  5. 2024

    Skin in the game

    Partner in a startup: building the product and carrying the outcome.

  6. 2025

    Passing it on

    Full stack instructor at Digital College, teaching new cohorts to ship.

  7. Today

    Still driving

    SaaS, mobile and automation in production — PontoGO, PeopleNity, Homefly and MeuProcesso.

What I do

Where I build

Experience

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.

  • PostgreSQL
  • Redis

Products in production

SaaS Platforms

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.

  • Go
  • PostgreSQL
  • Next.js
  • REST integrations

Work that runs itself

Automation & AI

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.

  • n8n
  • WhatsApp API
  • Node.js
  • Supabase

React Native

Mobile

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.

  • React Native
  • Expo
  • Supabase
  • Native maps

  • Mentoring
  • Code review
  • Open source

Let's talk

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.

Or take the long way

The same story is a valley you can drive through: a dirt track past six dated gates, a finish line at the top of the ridge, and six things hidden in the hills.
