Adriano P. Araujo

Angular Expert · Backend-fluent (Java, Go, Node) · Web3 & AI/RAG

5+ years building interfaces where the bug costs money - banking, fintech, blockchain.

I build front-ends for systems that handle real money, real contracts, real data. Not landing pages.

7COMm (current) Drex/Real Digital (Angular + Solidity), Banco Carrefour (fiscal dashboards), 7AIstream (RAG tooling)
Enacom Gerdau, VLI, Aliança → industrial simulation dashboards, SonarQube pipelines
Paytime Migrated React → Angular 12, built the UI from scratch
web3dev 2 years translating blockchain content, building courses for new Web3 devs
