Florida Senior Rails Engineer

Recently updated

Developer origin story I've always had a love for this craft. I was introduced to computers through my dad (works at Google). I went on throughout High School and college building robots, then teaching others how to build and program robots, and building my own self hosted networks and distro-hopping linux flavors Passions I believe that an expert developer is a unique asset to a company as they can drastically change its course. I like working with startups, and I have 15 years of tips, tricks, techniques, strategies from a technical perspective as well as an business/operational perspective. How I can help you I am a Rails and PostgreSQL expert. That means that I am very familiar doing things the rails way. There are things that you can only learn from being in a career for so fifteen years. I call it hidden knowledge. At some point you develop a sixth sense for when and how deep to test, which refactors are necessary, a set of practices for handling ActiveRecord associations. Unique skills that make me awesome I've written custom PostgreSQL extensions You'll notice with me that I am very quick on the keyboard, and between the well placed lame jokes, combined surgically precise problem solving, I have consistently told me that I am a pleasure to work with. Core Skills Ruby/Ruby on Rails ❤️ PostgreSQL ❤️ API ❤️ Turbo/HotWire ViewComponent TailwindCSS RSpec GoodJob/Sidekiq ActiveRecord/Sequel Documentation/Training Javascript Business Intelligence Analytics Mentoring Startups I built and sold directmailer.io, a direct mailer marketing platform that provides modern marketing conveniences to a legacy channel. Adheres to compliance within certain verticals, and provides deep integration like you're used to in SEO. I was hired to build the core infrastructure for floridahomesteadcheck.com, a property tax analysis tool that guarantees the lowest property taxes for Florida residents. You! You have an idea worth building

History After finding a hole in the company website after 2 months of joining as a System Administrator, I had the possibility to change from my role into my passion: software development. That's 17 years ago. From that moment onward, I learnt more languages (C, PHP, and amongst others my biggest love Ruby). Working with databases (most notable: MySQL / MariaDB, PostgreSQL), containerization, ops (using Terraform on AWS, GCP mostly). 7 years ago I discovered I am best suited to help my colleagues grow, and turned into a Rails/Ruby/database/Javascript/HTML teacher at a bootcamp, became a (part time) engineering manager. I've been implementing in Ruby/Rails for 50% of my time for the last 2 years, the rest leading teams and advising C suite execs. My main addition ...to any team is improving morale, by coaching and helping to build quality software, focusing on metrics for both errors and processing time, helping engineers of any experience level grow, and - as an individual contributor, but also as a leader - to only use complex solutions if the problem domain warrants it. Most recently I've switched towards building my own company that aims to reduce energy consumption and CO2 footprint for households. Tiny (IOT) devices, software in C, C++, Rust, and clearly building the required backends in Rails or Rust. Well connected: Apart from that, I am one of the organizers of Ruby NL, for which I've been hosting EuRuKo (2019), NoRuKu (2020), and monthly community events of Amsterdam Ruby organisation amsrb.org.

Full Stack Rails & React Developer with 15+ years experience

High response rate

Who am I? I am Tom Dallimore, a developer originally from the UK but now living in SEA. I currently work as a freelance Rails & React Developer, my 2 favourite frameworks that I thoroughly enjoy using (so far!). Additionally, in my spare time, I am managing a form builder I launched late last year called JotJab(jotjab.com) and building a subscription/membership application for the Shopify App’s ecosystem. But before we go any further, let’s get to my story and why I think we are a great fit for each other. My story Let’s get started. I am a 34 year old developer who has been developing all kinds of applications and software for the past 16 years. When I started software development (when I was about 16 years old) I learned the basics of HTML, CSS and a little bit of javascript. After that I moved onto PHP and C# for a small time but then stumbled upon Rails. I became intrigued, since when did writing code become so fun and fast? At the time I was working at Dyson as a C# developer, but in the evenings and mornings I was building my own little applications - a lot of fun. I eventually settled on creating an ecommerce app (yeah, I didn’t know at the time how much work that would be), which eventually grew into Trado - an open source e-commerce application. Fast forward a year or so and I was offered a job to work at an agency in Beijing. It was a contract based job which was primarily on upgrading, managing and debugging Rails applications, certainly an interesting experience. From there I decided I wanted to dive back into the world of freelance. I helped several companies launch apps using a mixture of React and Rails, including an online store for PPE supplies, a charity donation web + mobile app and an app for the Shopify Partners ecosystem. Why me? I love to experiment and build tools which help people’s everyday lives be more productive and fun! I would say the most rewarding part of being a developer is seeing apps I helped create become a rewarding tool for the user. I’m not just a developer Over the years I’ve worked on projects with teams and on my own. The latter meant I needed to take up other responsibilities to ensure the delivery of a product. These included tasks such as, server management, UX/Product design, graphic design (my father ran a graphic design agency) and from time to time marketing/branding. Guess you could call it a swiss army knife of skills! Side projects As I previously mentioned, since a young age I’ve always enjoyed tinkering with stuff in my free time. The most recent project is JotJab. At the time I was using Typeform to create forms for communicating with audiences on the web, but I couldn’t stomach their high pricing. So I built an alternative using React, Rails, TailwindCSS and Vite, all hosted on Hetzner and Cloudflare using the amazing Dokku engine (seriously, the best open source PaaS out there!). Staying in touch • I keep updated with the OSS community on Github • I follow a lot on Twitter and actively share daily • I follow a few YouTubers. • And I dabble in Reddit, from time to time. Soft skills I like to talk, throw ideas around, and have long conversations about certain topics. I love to experiment with “outside the box” ideas. I do have opinions, I like to discuss and have a conversation about my opinions, but I also love to change and adapt my opinions based on new information. After hours • I’m always keen to learn new technologies, currently experimenting with Go and Flutter • I have a passion for photography and videographer, mostly when taking trips into the countryside • I do enjoy watching a good series now and again, like Shogun There is a lot more I would like to talk about, but I hope I’ve already convinced you enough to start a conversation. I look forward to hearing from you.
