About Me

Full‑stack developer focused on shipping reliable, testable software. I work with JavaScript/TypeScript across React, Node.js and MongoDB. I built Open Telegram to Notion Bot to turn quick ideas into organized notes.
Currently at Mercado Libre, I work as part of the Financial Planning team, contributing to internal tools and processes that support strategic decision‑making. Previously at Ocelot, I built and maintained production‑grade applications that support chatbot experiences for universities, and at Kimche, I improved platforms that simplify school operations.
Open Telegram to Notion Bot is used by 1.1k users — a lightweight Telegram bot that sends messages straight into Notion so ideas don’t get lost.
I'm currently building NexisChat — a WhatsApp workspace for teams. The platform already includes multiple account support and message templates to streamline team communication, with exciting features like AI‑powered chatbots and smart writing assistance coming soon to help teams work more efficiently.
