Lead dev specialising in clean, maintainable code and keeping tech debt low

I'm a full-stack Rails developer with experience building robust, scalable products, whether as a Ruby monolith or with TypeScript/ReactJS frontends. I've been working with Rails for over 10 years (since version 3.x) and have specialised in creating and maintaining codebases that are easy for teams to read, understand, and maintain. Key to those goals are: using standardised code styles (ensuring RuboCop and the team's practices are perfectly aligned) writing well-structured, easy-to-understand and fast tests constructive and collaborative code reviews ensuring documentation, from git histories to READMEs and other materials (online and offline) records useful, meaningful information that can be easily kept up to date and in sync with any code changes I've recently been adding GraphQL to my skill set, which also includes PostgreSQL, ElasticSearch, Redis and other languages (Swift, PHP, JavaScript, and more). On the front end, I have experience with both Rails' native toolset and ReactJS, Next.js, and React Native. I also have experience with platform-native toolsets, such as SwiftUI, to deliver applications that feel intrinsically part of the user’s mobile experience. I've worked on projects of various sizes, from scheduling and booking software for a major tech training company to systems that enable TV distributors to sell thousands of hours of programming worldwide. Ideally, I'm looking to work on products with which I can feel personally invested – an exciting product or tech-for-good project would definitely suit me better than a fintech role.

Ruby on Rails Expert | Real Time App | NodeJS | ReactJS | NextJS

As a developer with over 7 years of experience, my journey began with a curiosity for how technology can be harnessed to solve real-world problems. Early on, I was drawn to full-stack development because of the opportunity to work across the entire application lifecycle. My expertise lies in Ruby on Rails, ReactJS, and React Native, but my passion for learning has driven me to continually expand my skill set with technologies like GO, NextJS, Node.js, and Python. One of my recent accomplishments was leading the development of a mobile app that streamlined a complex insurance process. By integrating APIs, building a custom voucher system, and enhancing the user interface, I not only improved the user experience but also contributed to a 10% increase in sales. This project reinforced my belief in the power of well-crafted software to drive business success. What sets me apart as a developer is my focus on problem-solving and scalability. I thrive on dissecting complex issues, whether it's improving performance by optimizing code or implementing a solution that scales seamlessly. I’m passionate about helping businesses grow through technology, and I pride myself on my ability to adapt quickly, learn new tools, and apply them to solve unique challenges. Above all, I am committed to building high-quality, impactful software that not only meets the needs of users but also drives meaningful results for the businesses I collaborate with. Whether it’s developing from scratch, maintaining existing projects, or testing new ideas with an MVP, I bring a versatile and solutions-driven mindset to every challenge.
