Fernando Augusto Gomes Pereira

I’m a software engineer who owns and ships production systems across backend, desktop, data, browser automation, and release infrastructure. I build Python services and operational workflows for complex accounting and government processes, taking multi-component work from technical design through production delivery.

I translate ambiguous accounting and government processes into technical plans and production workflows—coordinating changes across client, service, data, browser, and deployment components while protecting correctness and maintainability. I’ve reworked critical browser flows using asyncio, aiohttp, direct web APIs, and a custom Chrome DevTools Protocol library to improve execution on constrained networks.

I also focus heavily on concurrency and observability: I designed multi-browser processing with multiprocessing, shared client state, and queue-based scheduling, and I introduced execution-centered logging correlated across executions, clients, services, and companies. For reliable delivery, I automate Windows packaging and releases with PyInstaller, GitHub Actions, and Release Please, including a self-updating launcher with rollback for failed updates.
