About Me

Full-stack software engineer with over 10 years of experience designing and delivering scalable web platforms, enterprise applications, and internal systems. Proven success in both hands-on coding and technical leadership, having led cross-functional teams and worked directly with clients to gather requirements, architect solutions, and ensure timely, high-quality delivery.

Skilled in developing robust backend systems using PHP (Laravel, Filament), Java (Spring), and Node.js, as well as building dynamic frontends with Vue.js, AngularJS, and modern JavaScript frameworks. Strong experience in relational database design with MySQL, and performance optimization for high-traffic platforms.

Proficient in DevOps and CI/CD, managing containerized workflows using Docker, deploying to AWS, and automating pipelines with Jenkins and GitHub Actions. Integrated critical services such as RabbitMQ, Elasticsearch, and Algolia into production-grade systems.

Dedicated to software quality and maintainability, with extensive use of testing frameworks like PHPUnit, JUnit, Mockito, and Cypress. Comfortable in Agile environments (Scrum, Kanban) and effective in distributed teams using tools like Jira, Confluence, Slack, and Microsoft Teams.

I’m passionate about building complete systems—not just user interfaces, but the core infrastructure and logic that power modern software.
