About
I’m a full-stack developer with 6+ years of experience building and scaling web applications using React, PHP, TypeScript, and Node.js. I focus on backend logic, system integrations, and performance optimization, and I’ve worked on complex business logic, CRM integrations (Salesforce), and internal tools.
I actively leverage AI tools (Cursor, Claude) to accelerate development, improve code quality, and reduce production issues. I enjoy refining UX, boosting backend performance, and designing systems that reduce support load. Currently delivering internal tools at FirebirdTours, focusing on search relevance, data loading efficiency, and automation to streamline workflows and empower teammates.
