CTO | Engineering Management | Rails developer (12+ years) | Sidekiq | RabbitMQ | Hotwire, Stimulus and Turbo | AWS | GCP | Terraform

I’m a Rails developer with over 12 years of experience in software development, including 10+ years working hands-on with Ruby on Rails. Along the way, I’ve built all kinds of applications—automation tools, ERPs, inventory management systems, insurtech platforms, social media apps, and even AI-integrated solutions. I’ve always focused on creating large-scale, high-performance apps that can handle thousands of concurrent records without breaking a sweat. I’ve worked with both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB) databases, making sure they’re set up for speed and scalability. On the backend, I’m well-versed in Sidekiq and RabbitMQ for background processing, and on the frontend, I use tools like Hotwire, Turbo, and Stimulus to make apps fast and interactive. When it comes to deployment, I’ve got plenty of experience with Google Cloud, AWS, and Fly.io, which lets me build infrastructure that’s as reliable as it is scalable. The recent apps I've developed have included AI integration with OpenAI and Anthropic APIs. At present, I'm also setting up an internal LLM for speeding up software development. What makes me stand out? I code fast. Really fast. I’m great at taking an idea from zero to a fully functioning app in just days, without cutting corners on quality. Having worked in Asia and Europe, I’ve learned how to adapt to different clients and challenges, which helps me deliver exactly what’s needed, every time. Recently, I co-founded my own software consulting firm, where I get to use my skills and experience to help businesses grow and succeed. Outside of coding, I’m passionate about dogs, I love solving crosswords, and I’m a bit of a political nerd. These hobbies keep my mind sharp and my creativity flowing, which is probably why I enjoy tackling complex coding challenges. I know Ruby and Rails inside out, and I thrive on turning big ideas into reality—quickly and efficiently. If you need someone who can hit the ground running and deliver results, I’m your developer.

Building apps AI with Ruby on Rails + Turbo + Hotwire for Startups

In my 13 years of experience in software development, I've been fortunate to contribute to a range of meaningful projects: ✅ I co-founded a startup in the Philippines, where we successfully navigated the challenges of securing funding in Singapore. ✅ Pioneer developer with equity in a U.S. startup, which led to a successful exit in 2022, thanks to a collaborative team effort. ✅ Led the development of a UK e-commerce venture, which achieved $10 million in funding through shared vision and hard work. ✅ Built a successful SaaS tool for e-commerce SEO. ✅ Founding a software development agency where teamwork and client needs were at the forefront. Experience with Ruby on Rails I have had the privilege of growing alongside Ruby on Rails, starting my journey with this technology in 2009. Each version of Rails has offered unique learning opportunities, and I'm grateful for the insights gained through these experiences. 🚂 Rails 2.3.5 (2009 - 2010): My initial experience with Rails was during my final college year. At that time, I was working on a CodeIgniter (php framework) library for my thesis that logs and creates a UML to help developers debug code issues. The moment I actually read through and worked on a production Rails app which was a game on Facebook, I realized my thesis would not be useful in production. 😅The logs of Rails was really intuitive. 🚂 Rails 3 (2010): This version was a really big leap for Rails because of the Merb team merge. A lot of things were introduced on Rails on this version. The main issue at that time was migrating 2.3.X apps had a lot of issues, including Gems no longer working. 🚂 Rails 4 (2013): Transitioning to Rails 4 was a smoother experience. In January/Feb that year there was a mass assignment issue with Rails (where we could do SQL injections). On Rails 4, they made strong paramaters a default. 🚂 Rails 5: Turbolinks 5 and Action Cable was introduced. I think this was Rails answer to SPAs and hybrid mobile apps. During this time, I learned Turbolinks 5 and used Turbolink-iOS adapter to build and launch an iOS app on the Appstore. 🚂 Rails 6: Although ActiveStorage was introduced in 5.2. The projects I've worked on started adoption ActiveStorage at version 6. This is mainly because when you used ActionText which was introduced at Rails 6, you see the advantage of ActiveStorage when images are easily embedded on the WYSIWYG. 🚂 Rails 7: On this release, Hotwire became the default front-end framework for Rails. Hotwire included tools like Turbo + Strada to make it easier for smaller teams to launch cross-platform apps. Experience with Front-end Technologies I have extensive experience in front-end development, particularly with React and similar technologies, spanning over a decade. Here's a breakdown of my journey. <⁄>2012: Began with BackboneJS, where I first delved into MVC architectures in front-end development. <⁄>2013: Transitioned to EmberJS, which I found to offer a more robust MVC framework compared to BackboneJS. <⁄>2015: Adopted AngularJS, facing challenges with code organization due to the lack of standardized practices at that time. <⁄>2016 - 2017: Shifted my focus to React/Redux, a significant leap in terms of code structure and organization. The official Redux documentation greatly aided in establishing a consistent code organization strategy. <⁄>2018 - 2020: Integrated StimulusJS into my projects. <⁄>2021 onwards: Embraced the Hotwire stack, continuing my journey with the latest in front-end technology.
