ABOUT ME
Senior Software Engineer helping companies to create amazing products!
Senior Software Engineer helping companies to create amazing products!

Hi there! It's Ale. I'm a software engineer with nearly twenty years of experience helping companies build amazing products.

I feel at home with Ruby on Rails and Elixir/Phoenix, but I’ve also delivered high-quality code in Node, React, and Python.

Over the years, I’ve been the first technical hire, a full-stack developer, a tech lead, and pretty much everything in between.

I'm used to working closely with founders and small teams, moving from Plan A to Plan B to whatever plan actually gets us across the finish line.

I've helped startups build and scale web applications across finance, e‑commerce, esports, logistics, automotive, healthcare, edtech, and even the fashion industry.

I have experience with high-profile web apps serving millions of users and smaller platforms with modest traffic but incredible revenue.

I've helped companies launch SaaS products and ad-supported platforms in both B2B and B2C spaces.

Lately, I’ve been focused on integrating AI into web apps across esports, e-commerce, and fintech.

If you're building epic sh*t, don’t hesitate to reach out. Whether you're looking for a full-time hire or a part-time consultant. I'm always up for a new challenge and would love to chat.

Some apps I helped build:

I wrote Data Structures From Scratch, an ebook about creating essential, advanced, and persistent data structures using the Ruby programming language.

I live in Buenos Aires (UTC-3) with my wife and beautiful son.

If you made it this far, please check out my resume for a detailed version of what I've been doing.

Thank You!!

Ale came prepared with an MVP to demonstrate exactly what I was looking for and walked through it in depth. Ale also provided great tips and resources for me to continue my education. Will definitely be reaching back out to Ale when I run into a wall again.

I lead a mighty team of five engineers across the backend and frontend. I spend most of my time in the trenches—writing Elixir code, debugging PostgreSQL queries, shipping features, and making sure our systems scale reliably.

My work spans everything from designing data models and optimizing APIs to working with AI-powered extraction pipelines that parse complex SEC filings.

Canary is an ambitious product in a high-stakes industry. Building reliable systems that ingest, clean, and process massive volumes of financial data without slowing down has been one of the most rewarding challenges of my career.
