I am a software developer working on a production Django platform at Syzlab, and the founder of Teddy Code, where I have released 10 Android apps and 6 web products in the last 12 months. Before software I spent nearly 18 years in audit and finance, up to Controller, which is why I ask what a feature does to the business before asking how to build it.
Every product below is live, public and was designed, built and released by me under Teddy Code. No mockups, no case studies of work that never shipped.

An editorial guide to YouTube.

A financial eligibility engine.

A disposable chat for two people.

The web counterpart of the Playro app.
Seven focused offline-first utilities.
I tested giving the location filter away for free, expecting an easy win. Engagement went up and revenue went down. The test did not just pick a winner, it proved the filter was something people would pay for instead of a nice to have. Happy users and a healthy business are two different metrics.
Controller and Head of Accounting at GL Events Chile, and before that roles at Bupa, Edelcta, CMPC, Unilever, PDVSA Industrial, UHY International and KPMG, where I started as an auditor. I built a finance team from scratch, wrote its procedures, ran ERP migrations and reported to people who only cared about the number at the end. That is the part that does not show up in a git history and shows up in every technical decision.
Sixteen products in twelve months next to a full-time job only works with agents in the loop. It works because of how I use them, not because they write code while I look away.
Architecture, scope and data model are decided before a single line is generated. The agent implements a plan, it does not invent one.
One change at a time, reviewed line by line. A diff I cannot explain does not get merged, no matter how well it runs.
If it breaks in production it is mine. I read what ships, I debug it myself and I can defend every decision in a review.
The Claude API runs inside Hallazgo's publishing pipeline, MCP servers and headless automation handle the repetitive parts, and CI on EAS and Vercel ships the rest.
Product engineering, backend or full-stack, in a team that ships. I work from Santiago, Chile (UTC-3), with comfortable overlap for the Americas and most of Europe, and I can be hired as a contractor, through an EOR or B2B. I work in Spanish and English.
