Senior software engineer building whole products, from data tooling to on‑device AI.
I've been shipping software since 2010, mostly for media and retail companies. Today I'm a Senior Software Engineer at Globant, working with Disney Entertainment, and I like owning a product end to end: the data, the API, the interface and the release.
AI is part of how I work every day. I plan, build and review with Claude Code and a few MCP tools (a real browser, GitHub, current docs and web search), and I hold the result to the same bar as my own code: tests, review and a real run before anything ships.
Products and libraries I built and maintain, with live numbers.
Read, search and replay WhatsApp chat exports on your own device, with voice notes transcribed locally.
A desktop and web app for WhatsApp exports. Messages, photos and voice notes never leave the machine: Whisper runs in the browser over WebGPU, so after a one-time model download transcription needs no server. It handles chats with more than ten thousand messages, and the desktop app updates itself.
React to MySQL inserts, updates and deletes in real time by reading the binlog, with no polling and no database triggers.
Change data capture for Node.js. It grew out of the original mysql-events and runs on my maintained fork of the ZongJi binlog parser. Still downloaded thousands of times a month.
Dumps and restores large PostgreSQL databases over unreliable links, resuming where a dropped connection left off.
Talks the COPY protocol directly, splits big tables into volume-balanced chunks that retry on their own, keeps one consistent snapshot through pg_export_snapshot(), and streams zstd or lz4.
Watches files by glob and runs a different command per event, from one fast cross-platform binary.
Async on Tokio with debouncing, prebuilt binaries for five targets, published on crates.io.
Keeps WhatsApp bot auth sessions in Redis, Postgres or any Keyv backend, plus an in-memory chat store, so bots survive restarts.
A drop-in store for the Baileys WhatsApp library, typed end to end.
Connects to a free VPN server in the country you pick with one command, on Windows, macOS or Linux.
My most starred project. A small CLI over OpenVPN and the VPN Gate server list.
Also: kairos, a time calculator without datesbarracao-digital, a virtual queue for COVID-19 screening tents (2020)mongoose-timezone, a Mongoose plugin that normalizes stored dateshermes-smart-router, task routing for an open source AI agent
Fixes and features that landed in other people's projects.
Stopped the gateway watchdog from killing healthy sessions as hung, plus Bedrock context-window caching and auth cooldown fixes.
Faster session loading, CLI sessions kept visible in projects, and an accessibility fix.
Fixed multiline code block overflow.
Refactored the health status provider.
Per-method lodash imports to shrink the plugin.
Fixed a missing netsh argument on Windows.
16 years shipping software for media, retail and tax compliance.
