work
My first job: web applications for social programs of a UN-partner NGO, reaching young people across Brazil. Worked alongside UN Volunteers from five countries.
Projects 5
- PHP and MySQL, from database to front end
Systems for Brazilian federal agencies and enterprise clients.
Projects
What I did
-
PHP / Zend and Oracle, Java and .NET / SQL Server projects
-
A cross-platform quiz app for iOS and Android
Started on ten Java systems already in production, improved them iteratively instead of rewriting them, and became the bridge between development, infrastructure and business.
Projects
What I did
-
Moved the systems to Linux on AWS and hardened SQL Server
-
Designed a new microservices architecture: Java, Spring Boot, SQL Server, messaging and queues
-
Built on it the sync of accounting data (payables, receivables and more) between IEL-GO and FIEG systems
Embedded in US client teams, fully remote from Brazil. One of those clients became the next chapter.
Clients & projects 4
What I did
-
Built The Mission Zone’s MVP single-handedly, mentoring a junior developer along the way, 2018–2019
-
Placed with StartCHURCH, which later hired me directly
Eight years owning the platform end to end: how it is built and deployed, what it costs, and how AI helps the team.
Products 10
What I did
-
Platform 3
- Architecture and day-to-day operation of every product above
- Re-platformed everything: DigitalOcean → AWS, Ansible and Vagrant → Docker and Kubernetes, Bitbucket → GitHub with CI and tests on every push
- Split a single all-or-nothing deploy into independent apps that scale horizontally and deploy with zero downtime
-
Stack & tooling 2
- Upgraded the core stack from Symfony 3.4 to 6.4 and PHP 8.3; ported Kingdom Steward and StartCHURCH University from Zend to Symfony 6 with Claude Code (rolling out)
- Built sc, the team’s CLI: one command sets up a dev machine and standardizes daily work
-
Products 4
- Co-designed a microservices platform prototype with single sign-on (Keycloak) across legacy and current Symfony apps and Next.js frontends, meant to host Halo and later the whole suite, 2020–2021
- Took over Giving Halo and Launch Halo to keep them running: release-based deploys, tests on every PR, daily database backups
- Built and maintained the Attorney Network’s console and APIs, connecting church leaders with attorneys in every state, until the product was retired
- Modernized AppletBuilder (PDF courses and visual guides) with single sign-on, S3 storage and snapshot publishing; moved the Video Platform (recorded courses) to its own Next.js app
-
Cost, team & AI 3
- Runs the cloud cost program and automated manual billing work
- Onboards and mentors developers, including bootcamp juniors
- Brought agents, Claude Code reviews and a self-hosted MCP server into the team’s daily work
Started programming at 13, on my own. Everything after grew from that.
Bachelor’s degree in Information Systems, earned while working as a developer.
Aeronautics Institute of Technology (ITA). All coursework and credits finished; left in 2023 before the thesis defense.
Lab work
- Restructured the lab’s logistics-support planning tool (Go, MySQL), 2020

Started programming at 13, on my own. Everything after grew from that.
On the side
- 2017–2018SimUEGIndicators and monitoring system for Universidade Estadual de Goiás (Laravel, PostgreSQL).
- 2022SAZ SaúdeDesigned the health-benefits platform’s architecture from scratch (Laravel API, Next.js, Docker, CI/CD) and handed it over to their internal dev team.
- 2023Emigh LivestockShort contribution: reworked the infrastructure of a Symfony app still running on Ansible and Vagrant.
- 2024Wonder JournalShort contribution to a web and mobile app (Laravel, Inertia).
Outcomes
As of Oct 2026.
engineering
Systems and teams that outlast me: documented, shared and handed over.
- 18% → 3%of deploys could break the live site while rolling out, before vs. after I redesigned how changes ship
- 1h+ → ~5 minproduction deploy time after moving from Ansible on fixed servers to containers and CI/CD, so shipping up to 10 times a day became routine
- 0 “works on my machine”bugs since dev, staging and production started running the exact same images
- 1 commandto set up a dev machine on macOS, Linux or Windows: clone, run one script, the rest lives in containers
- < 5 minof downtime across eight Kubernetes version upgrades
- 40 min → secsto give every branch on staging its own copy of the database, so each change is tested against realistic data
- ~20 years of datamillions of records migrated into a two-way CRM sync, keeping sales and finance on one source of truth
- 14 appsrunning on one shared platform, each deployed on its own
- 10+ menteesengineers across four companies, from bootcamp juniors to senior hires
business
Tradeoffs explained in numbers — to engineers and to the CFO.
- 8 figuresyearly revenue of a business running on a platform I architect and operate
- −30%cloud bill in a single month
- ~80%less spent on testing infrastructure, same coverage: refactored code, restructured infrastructure, right-sized every service
- −22%database cost in production on AWS
- ~90%less load-balancer cost for preview environments
- 3 daysof the whole billing team’s manual work, done by one automation instead
ai
LLMs in the product, agents for the team — shipped, not demoed.
- MCPself-hosted server: the team asks an AI assistant about production data, read-only
- Agentsin the daily dev loop; this site was designed and built with them
