    Why Work With Me

    I'm a Problem Solver

    When you hire me, you're not just getting a developer—you're getting a partner who takes complete ownership of your technical challenges.

    High Ownership Mindset

    I take full responsibility for every challenge. From discovery to deployment, your problem becomes my mission until it's solved.

    No Excuses, Just Solutions

    No finger-pointing. No 'it's not my fault.' When something breaks, I fix it. Period.

    14+ Years Battle-Tested

    From startups to Fortune 500s—ETL pipelines processing 10M+ records, pharma systems in 23 countries, AI agents driving real workflows.

    Results That Matter

    I don't just write code—I build systems that drive revenue and maximize cost savings. Your success is the only metric I care about.

    "If there's a problem, I'll solve it. If there's a blocker, I'll remove it. That's just how I work."

    Behind the Code

    I believe in building trust through authenticity. Here's a glimpse into my world.

    My 1.5 year old 'code reviewer'

    "I work from home, surrounded by mate, coffee, and occasionally a tiny human who thinks keyboards are the best toys. This is the real me—focused, caffeinated, and always building."

    — Guillermo, from his home office in Uruguay 🇺🇾
