Senior Laravel Full-Stack Developer | SaaS, APIs, Vue/React/Next & AWS

I help companies build, improve, and take ownership of production SaaS and web applications. I'm a Full-Stack Developer with 6+ years of professional experience, with a strong focus on Laravel/PHP, APIs, Vue/Nuxt, React/Next.js, PostgreSQL/MySQL, and AWS. I've worked on both new development and existing production systems — including legacy applications that needed modernization, unreliable APIs that needed improvement, frontend systems that needed better component architecture, and products requiring ongoing feature development and maintenance. What I can help you with Laravel / PHP application development SaaS and business application development REST API design and development PostgreSQL / MySQL database development Vue.js / Nuxt.js applications React / Next.js applications Node.js backend development Legacy application modernization Taking over existing codebases Bug fixing and production issue resolution Reusable component libraries Unit testing with PHPUnit, Pest, and Jest AWS infrastructure and deployments CI/CD with GitHub Actions Redis caching API integrations Technical maintenance and ongoing development My approach I don't just focus on getting a feature to work. I care about maintainable code, reliable APIs, reusable architecture, testing, and understanding how a change affects the rest of the system. When taking over an existing application, I can work within the architecture that's already there, understand the existing codebase, fix problems without unnecessarily rewriting everything, and gradually improve areas that need modernization. Relevant experience I've worked across several production applications using technologies including Laravel, Symfony, Node.js, Vue/Nuxt, React/Next.js, PostgreSQL, MySQL, AWS, and modern CI/CD tooling. Some of my recent work has involved: Building end-to-end features across frontend, backend, and database layers. Designing and extending REST APIs for core application workflows. Modernizing legacy Node.js applications while maintaining production stability. Building reusable frontend component libraries to reduce duplicated development work. Writing unit tests around critical application logic. Diagnosing and resolving production bugs and recurring UI issues. Extending existing APIs while maintaining compatibility with downstream consumers. Working with distributed development teams and owning features through implementation and production support.
