I'm a software developer and the founder of OLON, a point of sale for coffee shops. I've been programming for more than ten years. I work with businesses to understand how they operate and build the software they need.

Founder and Forward Deployed Engineer, since 2025
I have a coffee bar, Hanami, and OLON started because I couldn't find a point of sale I liked for running it.
I built it around what I need behind the counter: to keep taking payments when the internet goes down and see how much I make on each drink, along with how much I sold.
I test it at Hanami first. Other coffee shops now pay to use the product too.
Open source macOS app
I use Claude Code and Codex every day. Setting up and reviewing agent configuration is part of my work, and agentsconfig grew out of that.
I brought global and per-project settings for Claude Code, Codex, Gemini CLI and other agents into one app. You can review and edit them in one place. The code is published under the MIT license.
A disk cleaner I shipped as a native macOS app, written in Swift. It includes automatic updates.
I start by understanding how the business works and what it needs to solve. I decide the architecture and break the work into scoped tasks. I started with Python and Django in 2015 and was a Tech Lead before I worked with agents.
Today I build with Claude Code and Codex. I set up their instructions and permissions and review every change before publishing. I decide what reaches production.
Claude Code, Codex, MCP, hooks, skills, Python, Django, TypeScript, Swift, Flutter, C#, Lua, PostgreSQL, Docker and AWS.
I build custom software for businesses, like inventory, invoicing, CRMs and websites. If your business still runs on a notebook or a spreadsheet nobody understands anymore, let's talk.
My coffee bar in Villahermosa. It's where OLON gets tested before anyone else uses it, and it's the reason I now also work on tech projects for the coffee world.
I also build developer tools, games and projects around coffee.
I've made games with Raylib-cs, Godot, Unity and LÖVE.
A tower defense game where the chibolas come rolling downhill and your guardians have to stop them. For Windows, Mac and Linux.
On play.tavo.dev I post the experimental games I make with AI. They run in the browser.
And one that isn't ready yet: Japonito, an app for learning hiragana in Spanish. I'm making it because I'm learning too.
A native Git client for macOS, with a view of the commit history in your repositories.
Alongside agentsconfig, I published these native macOS apps under the MIT license.
A 3D coffee atlas covering what's inside the bean, varieties, roasting and origin. The 3D models are generated with code.
Website and sign-ups for a barista competition in Villahermosa.
Website for a coffee shop in Villahermosa.
Most of my freelance work is private, so it isn't here. If you want to know what I've done that's close to what you need, just ask.

I started Dev Night Talks, a weekly series of tech talks, and I organize the AWS User Group Villahermosa. Before I went all in on development I taught Python programming classes, and I still have a YouTube channel with tutorials, even if I haven't posted anything in a while.
If you have a project in mind, email me at hola@tavo.dev.
Tell me what your business does, what you need to solve and whether you have a date in mind. That gives us a starting point to discuss the scope.
