As a Freelance Automation & Backend Developer, I build Python systems that run complex web workflows unattended. I reverse-engineer web APIs from captured traffic and automate dynamic applications from login through completion.
I architected a high-concurrency engine that coordinates parallel headless workers through an async signalling layer and transactional SQLite pool. I also built a custom asyncio TCP relay for proxy authentication and rotation where off-the-shelf tooling could not solve the problem.
I founded and run Eugénio de Amaral, Serviços Digitais, handling operations, client acquisition, and international partner outreach independently. I'm set up for full-time remote work and use AI-assisted development in my workflow.
