◆ 01 · About

A bit about me.

I started at Arrow Servicios on the commercial side, working with clients. When I began Engineering at ITBA, I moved over to the technical side and ended up building Arrow Connect, the internal app the whole company uses today.

In parallel I'm a teaching assistant for Imperative Programming at ITBA. I run office hours for first-year students — pointers, memory, recursion.

Since 2023 I've also been involved with the South American Business Forum: first on IT, then leading the speakers department of the 21st edition.

What I enjoy most: taking an idea, getting it to production, and watching real people use it.

What I've worked on.

An internal management app, an app for an international conference, a corporate training program and a speakers coordination.

Arrow Connect
Internal product2023 — Present

Arrow Connect

Cross-platform mobile app that manages Arrow Servicios's staff: attendance tracking, internal communication, task assignment and reporting. Built end to end — from the data model to the store deployments. Today it's a critical day-to-day tool for the company.

SABF Mobile App

Official app of the 20th edition of the South American Business Forum, used by attendees throughout the conference: agenda, speakers, profiles, networking and live notifications. I worked on the existing Ionic + Django base and shipped new features with the IT team.

Speakers Department — SABF 25

I led the speakers area of the 21st edition. Curating international speakers, managing invitations, agendas, on-site accompaniment during the event and production of the 'Between Life and Oblivion' track. A project that lived outside of code and taught me how to lead.

◆ 05 · AI

I work with AI every day.

It's a core part of how I develop, research and teach. I don't just use it — I understand it, push it and learn from it.

◆ Chatbot meetup

Buenos Aires AI community — talking models, agents and what's next.

I use LLMs every day to code, research, write and automate work. Power user of Claude, ChatGPT, Cursor and Claude Code— I switch between models depending on the task and I know each one's strengths.

In 2024 I designed and delivered an applied-AI training for over 40 people across Arrow Servicios, Arsec and Digifort Latam. I built the content from scratch: current landscape, applications by industry, prompting, automations and real use cases. I had to explain the technical side to a 100% business audience.

I follow closely how models, APIs and products built on top of them evolve. Whenever something new shows up — MCPs, agents, codegen tools — I try it and integrate it.
