Vitor
Souza,
a
senior
engineer
who
works
where
complexity
is
the
product.
Owned the full technical direction of a healthcare AI mobile platform — architecture, team direction and a realtime audio pipeline running in live clinical environments.
13+ years shipping production web and mobile products for startups, scale-ups and enterprise — KLM, Lufthansa Technik and Mazars among the end users.
Things I'm building, in public.
Products I'm shipping under Boomich, my independent studio. Some are live, some are still being built.

The problems I go looking for.
Senior and staff-level roles, remote or hybrid, where I contribute at the system level, not just feature delivery.
-
Complex product domainsTurning complicated rules and workflows into software people can understand and use.
-
Architecture that can evolveClear boundaries and deliberate trade-offs, so a product can grow without every change becoming a rewrite.
-
Unfamiliar territoryLearning the tools a problem calls for, testing assumptions early and finding a practical way forward.
-
AI integrationsBringing AI into useful product workflows, with reliability, clear feedback and a way to understand what went wrong.
-
Multi-team coordinationHelping people with different perspectives agree on the problem, the trade-offs and the next step.
