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 over 5 years of professional tutoring experience (and 1000+ positive reviews on Chegg tutors before they closed). I have worked with students of all levels of experience, from high school to grad school. I'm an expert on C, C++, Python, Java, functional programming languages such as OCaml, Haskell, F#, Prolog, Scheme/Lisp/Racket, etc. I can help with CS topics such as algorithms and data structures, Computer Graphics, Cryptography, Compilers, Programming Paradigms, CS theory (Finite Automata, Regular Expressions, Context Free Grammars, Turing Machines, NP completeness, etc.). I'm also happy to help with other math, such as Calculus, Discrete math, Statistics, Number Theory. If you want help with something other than what I've listed above I can usually debug anything, but I might be learning the material along with you.

“I recommend Lucas for his exceptional guidance in DevOps integrations and pipeline automation. He helped me debug complex issues and develop a deep understanding of DevOps methodologies, CI automation, and product integration all within a challenging on-premise legacy environment using BCM, a local container registry, and artifact management with mirroring. Lucas is a true expert who didn’t just solve problems for me but taught me how to approach and solve them myself. His support and deep knowledge made all the difference. It was a pleasure learning from him.“

“I had an amazing experience learning Power BI with Rafael as my mentor. He is superb—extremely knowledgeable, clear in his teaching, very professional, and genuinely passionate about helping others learn. He took the time to explain every concept in detail and ensured I was confident before moving forward. I highly recommend Rafael to anyone looking to upskill in Power BI. ⭐⭐⭐⭐⭐ He solved my doubt, so genuinely and professionally. I am his fan, not only for the Power Bi, but also for his personality. Note:- Its an AI written review but 100% genuine review from Chetan Gupta (India). Lots of Love, Thank you. You made my day“

“Lucas did an amazing job helping me with my problem. I got completely turned around debugging the issue for two days and I thought I tried everything. In the end, we tried the same everything, but more calmly, and there it was, problem identified. I can now move on to fixing it. But in the meantime, I also want to mention that it was great pleasure chatting with Lucas. His English is perfect, his technical knowledge is broad, his manner is pleasant, and he didn't talk down to me. I almost hope I'll have another problem to ask him about...“

“I had a fantastic session with Erum focused on understanding the internals of the Spark UI. She explained complex concepts like stages, tasks, and shuffles in a very clear and visual manner. What really stood out was how she connected the theory with real Spark execution graphs and showed me how to interpret performance metrics effectively. Erum also guided me through practical optimization techniques—like how to reduce shuffle overhead, how Spark breaks jobs into stages, and how to use partitioning intelligently. Highly recommended for anyone needing deep, hands-on Spark guidance“
