Backend and systems, from domain rules to interfaces.
My focus is backend and product engineering: turning real-world rules, data and constraints into understandable systems. Bioengineering and biotechnology are the direction I want to explore.
From problem to code: systems, technical choices and artifacts you can inspect.
An EPUB reader in the terminal. Text, images and reading state in one Go binary.
The interface changes; the session stays. Parsing, state and rendering have separate responsibilities.
Prototypes and experiments with a defined scope.

Delivery scheduling is more than storing dates: availability, permissions and conflicts in a Go API.

Comparing models also means investigating data, preprocessing and the limits of evaluation.
Three ways in — all of them start with a conversation about the real problem.
Something in my product is broken.
Rescue for existing web apps: bugs, integrations, UI, APIs or flows that need investigation and fixing.
I have a feature that needs to ship.
Implementation of well-scoped web features, mostly in React, Next.js and TypeScript, with the integrations they require.
There's a manual process that might be automatable.
Small automations, data processing and API integrations — after understanding how the process works today.
Domain modelling, persistence and separation of rules from interfaces. From reading state in Go to conflict queries in PostgreSQL.
Software that has to fit someone's workflow: keyboard navigation in tbook and e-commerce development with React, Node.js and VTEX IO at Amara Net Zero.
Python for exploring data, comparing models and examining what an evaluation actually establishes. Interested in applying that reasoning to bioengineering and biotechnology problems.

Fixed the README redirect to use the language selected in the app. An October 2024 contribution accepted into the project; the code and review are in the pull request.
Notes on implementation, state and project limitations.
Is something blocking your product?
Send me the context — a link, video, screenshots or a plain explanation. If it's within what I can solve well, I'll tell you how I'd approach it. If not, I'll tell you that too. I write back in Portuguese and English.
