Hi, I’m Leo — a Full-Stack Developer with 4+ years of experience building and maintaining production web applications using Ruby on Rails (Rails 7), Hotwire (Turbo/Stimulus), JavaScript, and Tailwind CSS. I’m focused on building clean, responsive, user-friendly interfaces while keeping implementations maintainable and scalable. I’ve shipped end-to-end features across multiple real-world systems used by insurance agencies and internal operations teams—ranging from dashboards and workflow screens to custom authentication. What I’m strong at: • Building responsive UI with Tailwind CSS • Interactive UI flows with Hotwire (Turbo/Stimulus) • Shipping full features end-to-end (frontend + backend) • Debugging production issues and refactoring for maintainability • Collaborating with teams to deliver reliable releases I’m open to opportunities as a Web Developer / Full-Stack Developer, especially UI-heavy roles where I can contribute to both frontend delivery and backend integration. Open to remote opportunities (PH-based, can overlap with US / AU time zones).

I'm a full-stack web & enterprise developer with 15+ years of experience. I am passionate about using software technology to solve customer problems. Analyzing requirements and carefully choosing and crafting optimal solutions is what makes me tick. When communicating with a client I always want to make sure that we're building the “right” thing, and then to make sure that we're building it in the right way. When elaborating a project I'm thorough and systematic, with an eye for detail. I am fanatic about quality (extensively reviewing and testing products that I'm delivering), paying attention in particular to aspects like security, performance, usability and documentation. I started out as a Java Enterprise developer, then becoming a freelance consultant moving into Web Development (dabbled a bit in mobile dev as well). My favorite tools are Javascript/ES6 (Node.js, React, Vue), PHP Laravel, and Ruby on Rails, however I'm pretty much technology-agnostic, always looking for the best tool for the job at hand. Full list of technologies that I'm comfortable with: - Javascript, ES6 - React, Redux - Vue.js - PHP / Laravel - Ruby on Rails - Node.js - Java / Spring - HTML, CSS3, SASS - SQL I have operated as an independent freelance developer for over 4 years and I am ready to help with your project today!

I build end-to-end web applications that scale from AI-powered dashboards to enterprise-grade backends. My strength lies in bridging modern frontend tech (Next.js, React) with robust backend systems (Node.js, Ruby on Rails, C#, Python) and seamless data layer integration (Supabase). Whether you need to: 🔹 Modernize a legacy Rails app with a Next.js frontend 🔹 Build an AI-driven SaaS product with React + Supabase 🔹 Integrate LLMs or custom ML models into existing platforms 🔹 Develop high-performance APIs with Node.js or C# … I deliver clean, maintainable code with a focus on UX, performance, and long-term scalability. I've worked remotely with distributed teams, shipped products for clients across finance and tech, and specialize in turning complex requirements into intuitive, production-ready solutions. Let's build something that works for your users and your business.

I'm the former co-founder, senior developer, and infrastructure engineer of a software company specializing in Rails and PHP.
