Hi, I'm Gustavo 👋

I'm a full-stack software developer focused on building practical web applications, distributed systems, and developer tools with .NET, React, Go, and cloud infrastructure.

My work focuses on shipping useful software: SaaS-style platforms, real-time applications, CLI tools, and experiments with AI-assisted workflows.

🚀 My Work

Current Focus

I'm currently focused on building production-ready applications that combine clean UX, pragmatic architecture, and reliable backend systems.

• Full-stack SaaS-style platforms with .NET, React, and PostgreSQL
• Real-time systems using SignalR and distributed service patterns
• CLI tools in Go and .NET
• AI-assisted workflows, agents, and practical automation

Projects

A few selected projects and experiments:

• 🤖 Wisp Bot — An app where you create AI teammates to help with everyday tasks, built with Electron, React, and TypeScript.

• 💵 BitFinance — Multi-tenant financial management platform built with .NET, React, and PostgreSQL, with an installable PWA and MCP integration for AI agents.

• 🧠 Echo — Speech-to-text app that turns recordings into polished posts, interviews, and notes using AI, built with React, .NET, and TypeScript, with RabbitMQ for asynchronous processing.

• 🦦 Lutra — .NET CLI for automated database and configuration backups on Docker-based Linux servers, with restore verification, retention, and offsite copies.

• 📝 DevLog — Go CLI for tracking development work, importing GitHub activity, and generating Markdown summaries with optional AI assistance and multi-device sync.

• 📊 ai-usage — Cross-platform Go CLI and terminal dashboard for monitoring AI coding assistant subscription usage.

Other Projects

• 👻 Whisp — Real-time chat application with direct messages, groups, channels, and presence tracking, built with .NET, React, and SignalR.

• 🎧 Lofi — Go terminal music player for streaming lofi from YouTube.

🔭 Currently Exploring

• Distributed application design and cloud architecture (Azure/AWS)
• Building practical CLI tools and terminal interfaces with Go
• Persistent AI agents, memory, and integrations with everyday tools
