Full Stack Rails & React Developer with 15+ years experience

New profile

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.

Full-stack engineer

New profile

👋 Freelance software engineer and full-stack Rails developer with 15 years of experience. 7 years CTO. My master was in mechanical engineering with orientiation in numerical methods, but I've always been in software engineering - in the web and Ruby on Rails world for the last 7 years, preceded by 8 years in the Java world. Until last year I have been CTO of a SaaS small business for a web/iOS/Android meditation app. I now offer consulting full-stack Rails consulting services to clients. In recent years I've expanded my front-end skills with Hotwire and Tailwind CSS, as visible on the front page of imagineclarity.com and other newer pages on the site. It features beautiful photographic images from Matthieu Ricard which are responsive in their resolution and change with dark/light mode. The layout combines flex and grid, ajax paginated lists, horizontal scroll containers with snap points, and more. The content is bilingual and loaded from a custom-built backend being migrated to Avo. I created part of the marketing copy myself. I've developed and maintained APIs and integrated third-parties such as Stripe subscriptions, Maichimp marketing and transactional emails, make.com automations. After deploying for years with Heroku, I now also maintain applications deployed with Docker on AWS, and deploy a simple app with Kamal as well. Last year I rewrote an Android app using Turbo Native combined with native screens and ExoPlayer. I am familiar with audio production, translation, copywriting, content management, and the basics of digital marketing. The above mentioned meditation app also features my recorded voice for one of the authors in the French version. Back in my early days, I installed and validated the control system for a medical treatment facility with 230 MeV cycloton and 4 treatment rooms (150M€). This lasted 3.5 years and involved 6 routers, 5 servers, 20 workstations, 40 control units & I/O modules, + integration with exernal systems.

Hi! I'm Liz 👋🏼 I'm about as full-stack 🥞 as they come. I started as a QA and automation engineer and now I'm a senior full-stack engineer focusing on Rails and React. Early on as a QA I worked on projects from writing SQL scripts to check data, to automation engineering, to React Native applications, and even helping implement Kafka instances and a team transition to Kubernetes. Then I moved on to development, mostly focusing on Rails / React stacks. I also am very comfortable working in Python. Now I've been a full stack developer for a few years, always carrying my QA mindset with me. I love exploring the ins and outs of a problem, and figuring out where I can pick it apart and expose weaknesses. I'm really great at building relationships with stakeholders, establishing trust and cooperation so that we can all move forward with a project in a very pragmatic way. Pairing with coworkers is always very enjoyable for me. I like the collaboration, but I really value the mentorship the most. Teaching juniors git has become a mainstay for me, as well as coaching them to maintain a calm mindset while debugging, encouraging them to move through issues in a systematic way. And of course I always fit in robust testing, showing folks how to create test suites and pipeline automation that will improve their workflow. Let's talk about how I can contribute to your team and stack 🙌🏻

GSoC'23 GitLab | LFX Mentee'23 @CNCF - Cortex | GSoC'22 GitLab | GitLab Core Team Member | GitLab Hero 🦊 | Git contributor

I am excited to share my recent accomplishments and experiences. This summer, I had the privilege of being selected as a Google Summer of Code 2023 Student Developer at GitLab for the second consecutive year. My GSoC project focused on enhancing GitLab's merge request comparisons using git range-diff, enabling effective code reviews and validating changes during rebasing. Here is the link to the project: https://summerofcode.withgoogle.com/programs/2023/projects/Z0MnDIgd Additionally, I am currently a mentee for The Linux Foundation's LFX Mentorship Spring 2023 Program, where I am actively involved in the Cortex Project. My contribution revolves around implementing an API in Cortex to simplify the migration of data from Prometheus to Cortex by importing old Prometheus TSDB block data. Here is the link to the project: https://mentorship.lfx.linuxfoundation.org/project/184ccb3e-6abe-4bf9-9659-b42b5c07c5a5 During the previous summer, I participated as a Google Summer of Code 2022 Student Developer at GitLab, where I collaborated with the Gitaly team, responsible for handling Git RPC calls within GitLab. I successfully integrated the mailmap feature into GitLab and contributed to improving the performance of the contributor graph feature by utilizing git-shortlog. One can explore my GSoC journey on my personal blog : https://siddharthasthana.dev/archives/ Here is the link to the project: https://summerofcode.withgoogle.com/archive/2022/projects/yaKP2iJK My GSoC work got highlighted in the GitHub and Git communities. Here is the link: — https://github.blog/2022-10-03-highlights-from-git-2-38/ — https://github.blog/2023-03-13-highlights-from-git-2-40/ — https://git.github.io/rev_news/2022/10/26/edition-92/ I have been actively contributing to other OSS projects like Zulip which is a real-time team chat system and Git, a distributed version control system. At IVY, I have written functions and tests for the ML transpiler and deep learning framework. In the process, I learned not only about how web platforms work, but also have some knowledge of how low level systems like kernel work. Here are the OSS contributions in GitLab, Git and Zulip: GitLab: https://gitlab.com/dashboard/mergerequests?scope=all&state=merged&assigneeusername=edith007 Git: https://lore.kernel.org/git/?q=Siddharth+Asthana Zulip: https://github.com/zulip/zulip/pulls?q=is%3Apr+author%3Aedith007+is%3Aclosed IVY : https://github.com/unifyai/ivy/pulls/edith007 Furthermore, I am thrilled to announce my recent recognition as a GitLab Hero and my inclusion as a Core Team Member of GitLab.
