Gabriel Duarte — Software Engineer and Product Builder at ConnectHub.
I design and ship products across SaaS, developer tools, automation, distributed systems and cloud infrastructure.
My work spans the complete product lifecycle: architecture, APIs, workers, queues, databases, real-time communication, native applications, infrastructure and production operations.
I turn complex infrastructure into reliable products with simple interfaces. The goal is not merely software that works, but systems that remain scalable, observable, maintainable and useful in real-world operation.
Product thinking + Systems engineering + Operational excellence

I like working across the entire lifecycle of a product — from the first architecture decisions to deployment and production operation.
Build simple interfaces over complex systems.
Good software isn't just code that works.
It should be understandable, observable, maintainable and capable of evolving without becoming a problem for the people maintaining it.
ConnectHub is where product engineering meets connected infrastructure. We build platforms that unify communication, automation, developer workflows and real-time operations behind clear, dependable interfaces.
I'm always interested in discussing:

Build. Ship. Improve. Repeat.
