Senior Software EngineerGeorgia, US
Hi, I'm Carlos.I turn concrete problems into simple, effective products.
Backend engineer by trade, comfortable across the stack. I like taking a real problem from idea to production, end to end, and using AI to get there faster.
Journey
From a first game in the Dominican Republic to building products from Georgia.
01Dominican Republic · Age 14
Dominican RepublicIt started with a game.
I taught myself to code at 14 by building a small platformer. No courses, just constant practice. The hardest part wasn't the code, it was getting people to actually play it.
That game opened the first door: someone who played it referred me to the company where he worked.
02Softone · 2019
Dominican RepublicSoftware a business runs on.
My first professional work was a desktop ERP at Softone. It taught me that software is something people depend on every day, so it has to be clear, reliable, and easy to use.
03ITelle · 2020
Dominican RepublicLeading, shipping, operating.
My first time leading a team, across very different projects. I learned to take apps all the way out: publishing mobile apps to the stores, deploying, and keeping them running.

04Remote · 2022
Remote · ChileGoing remote.
I moved to fully remote work, first with Drimo and then with ListoApp, a company based in Chile: mobile apps and multi-tenant platforms serving several kinds of users on shared infrastructure.
05Georgia, United States · 2024
Georgia, United StatesA new base.
I moved to the United States and kept building remotely, now focused on hotel connectivity at PriceTravel.

What's nextWhat I'm looking for.
A team I can connect with, where I can bring AI-powered ways of building software and ship products that solve concrete problems, end to end.
Off the clock I vibe-code games, push generative AI to see how far it goes, run, and hit the gym. Never stop learning.
- Product-minded
- AI-assisted development
- End to end
