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: * [Canary Data (Elixir/Phoenix - React)](https://canary-data.com/) * [Blitz (Elixir/Phoenix)](https://blitz.gg/) * [Superkind (Elixir/Phoenix)](https://www.linkedin.com/company/superkind) * [About Fresh (Elixir/Phoenix)](https://aboutfresh.org/) * [AR Workflow (Ruby/Rails - Node.js)](https://arworkflow.com/) * [SnapCell (Ruby/Rails)](https://snapcell.us.com/) * [Walkboard (Python/Django)](https://www.walkboard.com/) * [Sky Sports (Node.js - Python)](https://www.skysports.com/football) I wrote [Data Structures From Scratch](https://www.amazon.com/gp/product/B07MZZT6SW), 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](https://alemiralles.dev/alemiralles-resume.pdf) for a detailed version of what I've been doing. Thank You!!
I have been working in the industry for over 15 years working in startups through to large organisations. There are 2 things I am very passionate about; people and programming. Being able to program with others is what I do each day and I wouldn’t have it any other way. Currently, I am the CTO & cofounder of a technology company, and advisor to companies and I mentor engineers from various levels from interns to seniors. Code reviews and pair programming is the best way to share and learn from each other. These discussions are always valuable to all parties and I am always keen to discuss code.
