Hennadii A.

Senior PHP Backend Developer | PHP, Symfony, Laravel, WHMCS, APIs

I’m a senior web developer with over 15 years of experience building robust, production-ready PHP applications and full-stack web solutions. My main focus is backend architecture, system reliability, and API design, but I also deliver complete end-to-end solutions including frontend integration with JavaScript (ES6+), HTML5, and AJAX. I have extensive experience with Symfony and Laravel across multiple versions, designing and implementing REST APIs, complex business logic, and scalable database systems (PostgreSQL, MySQL, MSSQL). I’m familiar with Docker, CI/CD pipelines (GitHub, GitLab, Jenkins), and Linux-based production environments. Throughout my career, I’ve worked on a variety of projects, including SaaS platforms, billing and subscription systems, e-commerce, and enterprise web applications. I’m comfortable handling legacy systems, refactoring codebases, and implementing solutions that are both secure and maintainable. I enjoy collaborating with clients and teams, contributing to open-source projects, and delivering solutions that solve real business problems. My approach is pragmatic: I focus on building systems that work reliably, scale smoothly, and are easy to maintain. If you’re looking for an experienced web developer who can take ownership of your project from backend to frontend and deliver a high-quality solution, I can help you achieve your goals efficiently.
