I ship product end to end: apps in the stores, AWS back-ends on PostgreSQL and open-source tooling for AI-agent workflows.

OppyConnect

Messenger of the LinkBiz ecosystem, published on the App Store and Google Play.

Challenge
The platform needed its own conversation channel, with media, documents and voice, without relying on third-party apps.
Solution
I built the app in its entirety: one-to-one and group chat, media and document sharing, voice messages and search.

ImpactA complete app in production on both stores, maintained by me end to end.

  • Capacitor
  • Node.js

LinkBiz

AI-powered networking and business-opportunity platform for iOS and Android.

Challenge
A growing product with continuous demand for new features without giving up stability and security.
Solution
I work on the development team: new features, bug fixes and security items, from the front-end to the AWS back-end.

ImpactSteady delivery on a production app with real users.

  • Node.js
  • PostgreSQL

Duo

MCP bridge between two Claude Code instances: a Tech Lead delegates work to an Executor on another machine.

Challenge
A single agent cannot hold the tech lead's overview and the hands on a project living on another machine at the same time.
Solution
MCP servers on both sides, networking over Tailscale, local semantic cache, task delegation and a publish barrier via protected branches.

ImpactA working agent-to-agent flow with real risk containment in Git.

  • TypeScript
  • MCP
  • Node.js
  • Tailscale

claude-telegram-bridge

Self-hosted bridge that pings you on Telegram when a Claude Code session finishes and lets you continue it from the chat.

Challenge
Long agent sessions meant sitting at the computer just to know when they ended or needed a decision.
Solution
Per-OS binaries, long-polling with no public server, multiple projects and users on one bot, hooks installed automatically.

ImpactPublished with per-OS releases; a two-step setup.

  • Node.js
  • Rust
  • Telegram Bot API

VS Code Extensions

AI Diff Tracker and Mini Browser, published on the VS Code Marketplace.

Challenge
AI agents change many files at once; seeing what changed in real time is hard.
Solution
AI Diff Tracker visually shows the edits agents make as they happen. Mini Browser adds a side browser with tabs, bookmarks, history and an audio mode.

ImpactTwo public extensions on the Marketplace, built for my own daily workflow.

  • TypeScript
  • VS Code API

About

Product end to end, from the app in the store to the database.

I'm a FullStack Developer based in São José dos Campos, Brazil. Today I'm a Junior Developer at CDT Software, working on React/Vite front-ends, AWS-hosted back-ends and PostgreSQL databases. Before that I interned at SESI on internal systems, automation and infrastructure.

I like shipping the whole product: the published app, the API behind it and a well-modelled database. Lately I build tooling that makes AI-agent workflows (MCP, Claude Code) usable day to day.

Degree in Systems Analysis and Development from Faculdade de Tecnologia Senai Félix Guisard. Also: OOP and Databases with Java/SQL (Coursera) and Cybersecurity Defense Analyst (Cisco, in progress). Intermediate English.
