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.

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 🙌🏻

New profile

Seasoned code wrangler with over a decade in Ruby on Rails and a past life as a social worker and policy researcher. I've got a knack for translating geek speak for humans and wrangling stakeholder needs into delighted users and maintainable code. Somehow, most days, I still like my IDE. Looking to land in a place where code meets impact. Full stack developer that has spent over a decade in the Ruby/Rails ecosystem. I lean ops -> backend, but I can get in there and wrangle JS components and CSS if need be. I often wear at least a little bit of a product manager hat, have been a team lead on large projects, and I even try to remember to write documentation and technical briefs. I'm longwinded in slack, shy in person, didactic and friendly in code reviews, and occasionally down a rabbithole. Loves: Wrangling weird bugs and annoying APIs, refactoring, clear code (for the humans) and good tests (for the robots), figuring out the best places to deliver maximum impact and shipping quickly, teaching myself new things, compassionate communication and collaboration with multiple stockholders, making weird things happen in the CI pipeline Not so loves: JS in general, jerks, arrogance, watching junior developers not get the support they need and thinking it is their fault, refreshing staging for an hour wondering why my debugger isn't getting hit. -- Have worked in startups at all stages of their life cycle as both an introverted grumpy solo developer and team leader, helped make product decisions, mentored other developers, deleted prod a few times, etc. I chafe a bit at schedules, but occasionally I'll figure out a big that would have been a big problem in the future at 3am and just fix it. Love fixing those things. I can meeting during normal human hours though. -- Open to short and long term contracts and FTE for the right fit. Prefer chill flat organizations where everyone likes and respects each other and just gets stuff done. I've shipped features faster at those organizations than any that were focused on relentless hustle. -- Tell me why you believe in your tech and I'll tell you about one of my weird side projects like a Led Zeppelin button or a confessional that floats in the air. -- Have PhD level statistics classes buried in my brain somewhere, know my way around python and some data analysis, have built ETL pipelines - if it has to be done, I'll try to figure out a way to get it done. And the longer you hang around this world, you realize the most important programming language is being able to talk to people in kind and useful ways. -- Senior enough to know that sometimes it's the code you don't write that solves the problem ;) Junior enough to still get excited every time I make LEDs blink with magic words.

I started my journey in 2014 after graduating fresh out from college and getting into my first Job. My first project was really exciting and I was fortunate enough that I got a chance to work on it, that was to build a Software application that controls the drone when it is in the air and the user can draw an Area of interest where the drone would fly and as initially, I was the only one on the project and I myself did all the research work including the Mavlink protocol which was going to be used for communication between software and hardware, so an interesting problem I solved was implementing the custom messages that need to be sent to the bird and to cache a map on the file system So I created an algorithm to calculate the bounding box for an Area of Interest and download the map tiles in the background so that if a user is flying the drone where the internet is unavailable then also the map is visible on the desktop application. Then for one of the projects, I built a scoring and leaderboard engine for the same using a self-balanced binary search tree(SBBST). Detailed design is mentioned here (https://murtazabagwala.xyz/posts/algorithms). Recently built recommendation algorithm for one of the product. I am passionate about learning new tech and implementing the same also love exploring engineering blogs of tech companies to understand how exactly they solved the particular problem. I also believe tech can make a world better place to leave, and As engineers, we pride ourselves on the ability to problem-solve. I enjoy working through problem after problem, getting a precise solution. But I feel the impact is not related to the solution we build but it is equally associated with the problem itself, So, I feel if we could simplify the problem and understand the problem itself first than start building a solution in the first place then I think we can make a better impact. But, sometimes we get so focused on solving the problem in front of us that we don’t stop to think if the problem is really is the problem. As per my professional summary. I would like to highlight some of my skills:- Good understanding of Algorithms, Data Structures, Design Patterns, Object-oriented/ Functional Principles, and Software architectures. Good communication skills and experience in working with teams of different sizes. Knowledgeable of Backend and Frontend best practices. Also, I would like to mention some of my achievements and contributions as well:- Recently my blog got published in Rubyweekly's 597, 600, and 603 editions. Very popular Ruby weekly digest. Created a library called SAUR that parses the swagger file and generates RESTLET routes (github.com/murtaza-bagwala/saur). Contributions to open-source space https://github.com/chatwoot/chatwoot/commits?author=murtaza-bagwala Created an algorithm to calculate the player's rank and leaderboard in linear time using the Self Balanced Binary Search Tree which was used across all our igaming trivia apps (github.com/murtaza-bagwala/ranking-and-leaderboard).

I am most familiar with Postgresql as the database layer - construct performant queries to minimise database calls, using includes, joins, where and scopes. (I recommend the Bullet gem) - use service objects to perform tasks consistently, and where appropriate to provide a wrapper layer for simple use and testing. - use workers to perform asynchronous tasks - design and manage API service to send / receive data to and from the Front End (or Mobile app) as both REST and GraphQL - work with AWS services such as Lambdas, S3 and SQS, using client libraries where appropriate - interact with external APIs, typically using libraries such as HTTParty and rest-client - write excellent tests that are thorough, performant and importantly; document the intent of the code under test. I have used RSpec in my professional work. - give good PR feedback in a manner that is constructive, clear and kind - work with CI Pipelines. I have used Bitbucket, Github and Buildkite - manage rubocop to align developer styles - mentor junior staff I love the work that I do, and I am really lucky that I really enjoy working for the company I currently work for. I am not looking for full-time work, only for part-time contracting opportunities. I worked for many years as an Electrical Engineer working with electronics and renewable power before making a transition into Software Engineering. The problem solving skills I used then are still useful now.
