I'm a software engineer from Brazil. I've been building things for over 15 years, from mobile apps and high-traffic platforms to backend systems, infrastructure and developer tools.

I've worked across fintech, payments, insurance and a few other industries. Somewhere along the way, I got particularly interested in what happens behind the scenes: how systems scale, how things communicate, how to make complex software simpler.

These days, I spend a lot of time with Go, distributed systems, AI, infrastructure and whatever interesting problem I happen to be working on.

I also have a habit of building tools because I couldn't find one that worked quite the way I wanted.

Go TypeScript React React Native Node.js Kotlin .NET PostgreSQL MySQL MongoDB Redis Docker Kubernetes AWS

PyTorch Transformers Hugging Face LangChain LangGraph Ollama OpenAI API MCP Embeddings RAG Vector Databases

Beyond the stack, I work a lot with APIs, system design, distributed architectures, CI/CD and infrastructure. Lately, I've been spending more time on LLMs, retrieval systems and making AI useful in actual software.

Most of these started with a pretty simple thought: "I wish this existed."

Developer tools & infrastructure

• Lily DB: A native database workspace for macOS. Nine database engines, query tools, performance tracing, migrations and AI that actually understands what you're working with.
• Kiln: Background jobs for Go, inspired by Hangfire. Uses your existing SQL database instead of requiring a separate message broker. Retries, scheduling, workflows, transactional enqueue and a dashboard included.
• Orbit: Making server management and Kubernetes deployments less painful. Your infrastructure, without having to fight it.
• Barney Kube: A native Kubernetes client for macOS. Browse resources, inspect workloads, access terminals and forward ports without living in the command line.
• Marshall MQ: A native Kafka and RabbitMQ client for macOS. Inspect queues, track down troublesome messages and understand what's really happening.
• Vue Router NS: Bringing the Vue Router experience to NativeScript-Vue 3, with TypeScript, native navigation, guards, deep links and modals.
• Popup UI: Customizable popups for React Native.
• Jolt: Making animations in NativeScript feel effortless. Springs, keyframes, presets, stagger and sequences, all powered by native animations on iOS and Android. Works across NativeScript frameworks.
• NativeScript Preact: Build truly native iOS and Android apps with Preact. JSX, hooks, and native UI components powered by NativeScript. No WebViews.

AI & productivity

• Cortex: Persistent memory for Claude Code. Local-first, built to preserve useful context without wasting tokens.
• Ted Agent: A macOS AI agent that lives in the menu bar, right where I wanted one.
• Cortex Shelf: A little productivity toolkit for the Mac notch. Clipboard history, notes, screenshots, files and a place to drop things.
• JobMorph: Helping people tailor their CVs to job applications using AI.

A little outside the usual developer tooling

• Yummo: A restaurant operating system connecting menus, orders, kitchen, customers, staff and finances. Built for the web, desktop and mobile.

You can find more of what I'm working on at Cortex Labs.

I also teach software development, sharing what I've learned over the years while continuing to learn myself.

I'm particularly interested in distributed systems, software architecture, infrastructure and understanding how things work under the hood.

I enjoy building things from scratch, questioning existing approaches and finding simpler ways to solve complicated problems.

Sometimes that turns into an open-source library. Sometimes a full product. Sometimes just another experiment that teaches me something.
