ABOUT
Pedro Bertão
Senior Software Engineer
I'm a software engineer based in Florianópolis, Brazil, with more than eight years of experience building software across fintech, blockchain, enterprise platforms, and cloud-native applications.
My strongest background is backend engineering, particularly Go, distributed systems, and API integrations. Throughout my career, I've worked on products used at scale, led engineering teams, contributed to architectural decisions, and helped modernize existing systems.
I enjoy taking ownership of complex problems, understanding the business context, and building solutions that remain reliable and maintainable in production.
More recently, I've expanded my work into Applied AI, integrating LLMs and automation into practical software workflows while bringing the same engineering discipline I apply to traditional backend systems.
I value clear communication, pragmatic technical decisions, continuous learning, and teams where engineers are trusted to contribute beyond implementation.
