Fullstack (Node · React · TypeScript)

I deliver scalable APIs, tests and automated deploys — clarity and end‑to‑end delivery.

Node.jsReactTypeScriptPostgreSQLDocker

Available for Jr→Pleno roles — open to CLT (Brazil), contractor and freelance.

APIs with tests and CI/CD — e.g.: reduced regressions by {metric}

End‑to‑end delivery: design → deploy → monitoring (Postgres, Docker, GitHub Actions)

Build‑in‑public: posts with before/after and data — links to cases in portfolio

things i built

(that i can actually show you)

multi-tenant dashboard

TypeScriptNode.jsPostgreSQLCI/CDObservability

Result: -35% incidents in 4 weeks. Custom dashboards + alerting.

how i work

(more or less)
01

understand

what do you actually need? not what you think you need. we talk.

02

design

architecture, data models, api contracts. boring stuff that saves months.

03

implement

clean code, types, tests, CI/CD from day one. ship fast, fix faster.

04

test

unit, integration, e2e. if it compiles but doesn't work, it's not done.

wanna build something?

i'm available for projects, collaborations, or just a good conversation about tech and life. no forms, just email me.
