Backend-focused full-stack engineer building reliable web products. Currently a Software Engineer at TestBox.
About
I'm a software engineer who likes turning fuzzy product ideas into systems that hold up in production. I started in backend with Python and Django, picked up the frontend along the way, and today I work mostly across the backend of a SaaS product — APIs, data models, integrations, and the unglamorous plumbing that makes a product feel fast and trustworthy.
My career started in 2022 at Concordia Labs, building backends with Django — apps, data models, and APIs — and soon moved into the frontend with JavaScript, React and Sass. Tools like Poetry, Docker and Postgres became part of my daily workflow.
Since 2024 I've been a Software Engineer at TestBox, working primarily on the backend of the platform. I care about clean data models, well-shaped APIs, and code that's easy for the next person to reason about.
Experience
Mid-level engineer working mostly on the backend of TestBox's platform — building and maintaining APIs, data models and integrations, and shipping features end-to-end across the stack.
Built Agronix Web Service — a platform to manage a proprietary Android device and its app, with app version control, over-the-air updates and real-time device control over WebSockets. Worked across the web stack (Next.js, Node.js) and the Android mobile app.
Built Hapolo, a vehicle GPS tracking platform — real-time location tracking and fleet monitoring on the web, with a Django backend and JavaScript frontend.
Started in backend with Django — building apps, data models and APIs — then moved into the frontend with JavaScript, React and Sass. Worked with Poetry, Pip and Docker day to day.
Skills
Projects
TestBox builds demo agents that generate realistic data and auto-maintain product environments for testing, live demos and sandboxes — so B2B SaaS teams can sell with their actual product instead of faked screenshots. I work primarily on the backend: APIs, data models and integrations.
A CMMS (Computerized Maintenance Management System) for asset management and preventive maintenance. It keeps all maintenance data in the cloud and centralized on a single Web and Mobile platform. I worked across the Django backend — data models and APIs — and the React frontend.
Sports Club Management SaaS
An all-in-one management platform for sports clubs, gyms and personal trainers. It handles workouts, activity classes, finances, banking sync and physical access control — replacing several disconnected tools with one product. Built across Django and React.
IoT Device Management
A web service for an agriculture company to manage a proprietary Android device and its app — registering app versions, pushing over-the-air updates, and controlling devices in real time over WebSockets. Built at Manp Tecnologia.
