Rodrigo's Personal Site

What I do

I'm a mechanical engineer specializing in HVAC and a freelance developer. I combine technical engineering knowledge with modern development to create practical and efficient solutions.

I've been programming since childhood (Flash/ActionScript 3.0 era) and today I focus on simple solutions that a solo developer can maintain. I'm a fan of lean apps, anti-ERP, with real focus on users.

Main stack

Frontend: React, Next.js, TypeScript, Tailwind CSS
Backend: ConvexDB for real-time, REST APIs
Sites: Astro for maximum performance
Exploring: Rust, Elixir, TigerBeetle

I choose technologies for simplicity and productivity, not hype. Every tool needs to solve a real problem.

Current projects

📦 Warehouse Watcher

Inventory control system for small businesses. Anti-ERP, focused on being simple to use without losing essential functionality.

Stack: Next.js + ConvexDB + TypeScript. Clean interface, no unnecessary complexity.

📝 Quiz Platform

Question system with intelligent filters and performance reports. Focus on user experience and useful data.

🎮 Educational Game

Interactive quiz with animated map. Simple but effective gamification for educational engagement.

🏗️ Modular HVAC ERP

Custom system for my company: proposals, contracts, inventory, finance. Modular to grow as needed.

🌐 Landing Pages

High-performance sites using Next.js and Astro for clients. Optimized for conversion and speed.

Work philosophy

I believe in software that solves real problems without adding complexity. Every feature needs to justify its existence. I prefer 10 well-made features over 100 poorly implemented ones.

As a solo developer, I prioritize technologies that allow me to maintain and scale projects alone. Clear documentation, simple code, architecture that doesn't become a nightmare after 6 months.

Combining engineering and development, I have a unique perspective on systems: I understand both the technical side and real user needs.

Let's work together?

Open to projects that make sense. I like to understand the real problem before proposing solutions. I prefer long-term partnerships over one-off jobs.
