Hire Ruby on Rails developers

I have been developing for the web since 2007 and with Ruby on Rails since 2012. I am skilled in backend development as well as server-side rendered HTML. I have worked on a variety of projects from small scale to large legacy for a variety of different clients and employers. I have worked for startups, corporations and non-profits. I have experience working as part of team using agile methodologies, as well as working as a solo developer directly with clients. I am passionate about continuing my own education as a developer as well as helping others learn. I was the organizer of the Ruby meetup in Ann Arbor for over five years. I have also spoken at numerous conferences and user groups.

Highlights: 10+ years of experience as freelancer in FinTech,Healtcare and HR applications Proficient in Ruby on Rails on the backend, and lots of other tech on the frontend. Specialized in optimizing, legacy code, database performance. Experience as DevOps well. Full background: As a nineties kid, I was already tinkering/dabbling around making games and invoicing software on our first pc at home. In university, while doing my engineering and mathematics degrees, I was scripting and using a lot of different technologies on complex physics problems. In 2012, I discovered Ruby/Ruby on Rails and a lot of things just clicked/felt right. I've specifically looked for RoR startups, joined an early stage FinTech startup that exploded and has had a successful exit. From then on, I turned it into my career and never looked back. I worked in FinTech, Healthcare, HR applications, picking up different domains and iterating upon complex calculations on the way. I've architected several green field/new applications from the ground up, all of them are still in use today. Amongst them are some high traffic enrollment systems in sports and leisure. I've worked with all Rails versions, even facilitating a migration from a huge (400 models plus) legacy rails 2 application to modern standards. Along the way, I've seen some very interesting PostgresQL optimization problems. You can't go so long and not pick up some DevOps as a side quest, so worked with terraform, chef, Ansible, Kubernetes and all kinds of provisioning/hosting/deployment tools and pipelines. I've used most modern frontend frameworks (React/Redux, Vue, Angular, Ember) on different projects but for smaller applications I tend to prefer to keep it simple using Hotwire.

Hey there! I'm an experienced software developer with a strong background in Ruby on Rails, Hotwire (including Turbo, Stimulus, and Turbo Native), Jumpstart Pro, APIs, Postgres, Tailwind. I'm really passionate about crafting high-quality, efficient, and user-friendly applications. Recently, I had the pleasure of working with inkwire.co, where we developed cross-platform applications using Turbo Native. We optimized high-traffic pages, reducing load times by ~80%, we improved database performance through query optimization, task offloading, caching, and refactoring model associations. I also collaborated with collide.app on a contract basis, where we developed a cross-platform application using Ruby on Rails and Turbo Native (Jumpstart Pro). We implemented intuitive UI/UX designs using Tailwind CSS, ensuring a seamless and visually appealing user experience. Prior to these contract roles, I worked with oblsk.com, where we contributed to remarkable projects like plt4m.com. We solved user stories end to end, conducting testing (Mini & Capy), and implementing responsive CSS (Tailwind). Another notable project was haymakersforhope.org, where we integrated a Strapi API for a headless CMS and designed a responsive interface using Tailwind too. In my spare time, I'm dedicated to giving back to the community through organizations like Ruby for Good. I've actively participated in their CASA project, assisting with both small and large issue resolution. Collaborating with like-minded individuals to make a positive impact is truly fulfilling. I consider myself on being resilient, resourceful, and emotionally intelligent. I possess strong communication skills and always strive to deliver on time. 🇺🇸 English - Professional 🇲🇽 Spanish - Native CASA project: https://github.com/rubyforgood/casa/commits/main/?author=dominiclizarraga Personal blog: https://github.com/dominiclizarraga Resume: https://standardresume.co/r/YcQ-LtWoMGJlQFJz4IvH5

Hi, I'm Mwala and I love building for the web. I have been writing rails programs since 2022 and I have been hooked to this framework ever since. Rails really brings out the creative in me what people online call the developer brain. The framework's full-stack experience is one I have really enjoyed especially when you integrate Hotwire 🔥. I used django before and had a good experience with it won't lie. I have also done so work with Gin with go-lang and React just for the frontend(that what it should be used for). I have done some game development in the past and computer vision work, it was an exciting time. Game dev is something I might go back. Okay, I don't spend all my time on development, I try my best to stay in shape, football (soccer) being my go to sport. I really like watching and playing the sport. I think If I wasn't a developer I would have been playing football professional 😎. I have gotten into the habit of watching the UFC and motorsports, F1 to be specific and tennis, man I wish I knew how good this game was.
