Freelance Ruby Developer - Ale Miralles
Freelance Ruby Developer5.0 (39 reviews)

I started my programming career creating line of business applications for investment banks and slowly transitioned into web development roles working with Ruby on Rails and Elixir/Phoenix. I have experience working on high-profile web apps serving millions of active users and also smaller websites with modest traffic but terrific revenue. For the past eight years, I've been working remotely for American companies, mainly doing web development and playing tech-lead roles in several projects. I'm used to working with founders and CTOs, going from Plan A to Plan B to a plan that works. I've helped companies build MVPs, scale projects, and maintain large-scale systems handling millions of requests a day. I'm comfortable doing code reviews and pair programming sessions. These are some web apps I've worked on in the past couple of years: * [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!!

Freelance Ruby Developer - Uzair Faisal
Freelance Ruby Developer5.0 (3 reviews)

I'm a **polyglot fullstack software developer** (*I'm able to effectively work with multiple languages, tools, and frameworks*) with over 13+ years of industry experience in web application development. I'm also an instructor and mentor in various bootcamps having lead class cohorts, mentored groups of students and 1:1 tutoring sessions. I'm experienced in **Python**, **ECMAScript** (Javascript or Node.js), **Java**, **C#** **Ruby**, **PHP**, and even **Scala**. I work in both frontend and backend spectrums of the web stack, so whether you're debugging something in React.js or you're stuck on a complex SQL query, I'm more than happy to help in your code debugging adventures. My instruction style is that I like to guide the student towards learning *how* to solve rather than simply giving you the solution - I don't believe a student should be stuck on always referring back to a senior developer to get unblocked, but should be empowered to solve their own problems. Now that's real mentorship!
