Two full careers — delivery and engineering — pointed at the same problem.
I build products end to end: the backend that has to hold up, the frontend people actually use, and — for the last three years — the AI layer in between.
The foundation is backend engineering. Seven years of Ruby on Rails, REST APIs, PostgreSQL, Sidekiq and asynchronous processing in SaaS products for healthcare, insurance, logistics and compliance — the kind with real users, real SLAs and plenty of legacy code. On the front end I work with React, JavaScript and TypeScript, and I've shipped mobile with React Native.
Over the last three years I've been building with LLMs on top of that: document workflows in production, multi-agent pipelines in Python with tool calling and MCP, prompt design and evaluation, and the unglamorous part — cost, latency and what happens when the model returns something wrong.
Before engineering I spent eight years in quality management and IT project delivery at AT&T–DIRECTV, running project portfolios across Argentina, Chile, Peru and Uruguay. It's why I ask what outcome we're buying before deciding what to build.
I also run my own products under Orbital Labworks — Hausefy and Mottorfy. There I own everything: product, architecture, code, the platform integrations they depend on, and the infrastructure underneath. It's the fastest feedback loop I've found for becoming a better engineer.

Senior Software Engineer
Compliance & field operations
Lead end-to-end technical initiatives for operational audits, traceability and testing flows on a compliance-heavy SaaS platform serving the backflow industry.
Drove team adoption of AI-assisted development (Claude Code, Cursor, GitHub Copilot, Augment) for implementation, legacy refactors and review consistency.
Ship backend and frontend changes together — Rails services and the JavaScript UI on top of them — so features land complete instead of in halves.
Reduce regressions by extending RSpec and Capybara coverage.
Work with Product and QA on scope and prioritisation, defending delivery predictability.

Ventures & AI Systems
Products I design, build and operate end to end under Orbital Labworks, my own studio. This is where my Python, agent and platform-integration work lives — and where I answer to the users directly.
The studio behind the products below. I run the full platform layer myself: domain and DNS, hosting on Firebase Hosting and my own Linux VPS, Google Workspace administration, and the developer-platform side — Meta Business verification, app review, OAuth app configuration and credential management for every integration the products depend on.

A CRM for real estate agencies that pulls Zonaprop, Argenprop, Mercado Libre and social channels into a single inbox, so agents stop losing leads across five open tabs.
I own product, architecture and implementation, including the whole integrations layer: Mercado Libre and Mercado Pago apps running on production credentials with OAuth 2.0 + PKCE, refresh-token rotation and full webhook coverage, plus Meta Graph API for the social side. Built multi-tenant from day one, designed to scale to 500+ agency accounts.
A modular ERP for the automotive trade. Replaces the spreadsheet-plus-WhatsApp stack with one connected system covering workshop, dealership, lubricentro, carwash, fleet and payroll: work orders, stock, cash, invoicing and reports.
