Full platform for a natural-food store in Córdoba: public storefront, management backoffice and print-material generators. Data modelling, role-based permissions and field-by-field auditing in Laravel; the storefront is generated static HTML in TypeScript, with no framework and no external JavaScript. Custom deploy, verified automatically against production.

Automation toolkit for Rekordbox. Signal processing with librosa and scipy to detect each track's structure, and reverse engineering of Pioneer's binary formats to write the markers into its encrypted database. Building a set is a search problem: rules versioned as data and ordering by harmonic compatibility.

Landing page for an audiovisual studio. Hexagonal architecture: content arrives through a port with swappable adapters —CMS, frozen snapshot and static— so the site survives the backoffice being shut down. Accessibility as a gate: axe and Lighthouse stop the pipeline if a WCAG violation shows up.

A glossary and market snapshot to understand Argentina's capital markets without being an insider. PDF parsing of IAMC reports, a data contract validated with Zod and charts in Recharts. The product work is in the explanation: what each instrument is and how to read its volume.

The dollar day by day, and who buys and who sells each month. An ingestion pipeline that checks itself: it validates the schema, cross-checks the spreadsheet against the PDF and refuses to publish when the data fails its controls. Time-series modelling, CSV download and an estimate of my own for the current month, with the method laid out.

My own product to see an entire portfolio in one place. Broker integrations, each with its own authentication scheme, a market-data pipeline with fallback across sources and a multi-currency returns engine. On top of that, product features: Freedom Score, consistency streak and capital projections.

Multi-tenant SaaS for law firms. Per-tenant isolation in the data model, in the token and in every query, with tests that verify the crossover. Versioned migrations, a custom Tailwind design system, and the identity provider behind a contract so it can be swapped without touching endpoints.

I launched Dólar Oficial inside Ualá — a simple, frictionless way for anyone to save in US dollars. I coordinated business, legal, compliance, ops and product to make it accessible to everyone. Today it's part of the app's savings offering, available to any user in a few taps.

Led the full revamp of the product to invest in Argentine stocks, bonds, T-bills and CEDEARs. It's now live, so more people can take their first step into the market with a simple, clear and trustworthy experience.

My own system to understand the user without waiting for the next report: cohorts, churn, portfolios and flows ready in hours. From weeks to hours, and an analysis you used to have to request now runs on its own.

Added the remunerated account to the bank's savings offering — a way to make money earn on its own, every day, with zero effort from the customer. I coordinated business, legal and tech for a simple, safe and profitable experience.

Product owner of mutual funds — the capabilities to invest in funds from the bank's app. I took what I learned on Inversión Rápida so more customers put their money to work, coordinating product, tech and business.

I owned Inversión Rápida for 3 years at Supervielle — from business analyst to Product Manager. The experience that lets any bank customer invest in just a few taps; I led the team behind the final version, which delivered 10× more active users and 10× more volume.
