hi, i'm Guilherme.

i'm a software engineer in são paulo. today i work at AIDM, helping companies in health, education and investment use artificial intelligence in real work — not only in a presentation.

in my free time i make my own products and walk with other devs on their path.

where i work

at AIDM, we don't hand over a tool and leave. we sit with the people who do the work, understand how things really run, and build what helps — inside companies in health, education and private equity.

it's the kind of work i like: slow at the start, so it can go fast later.

things i made

i test everything on myself first

i help other devs grow

i walk with people who are changing phase — from junior to mid-level, from mid-level to senior. we look at where you are, agree where you want to go, and go together, with frank conversation and goals that fit your routine.
