Message

At Salesfloor (now part of Tulip), I modernized legacy APIs by migrating them from WordPress to Silex and then Symfony, while refactoring core business logic to improve maintainability and stability.

I overhauled automated testing with Codeception, introducing database transactions that reduced the test suite’s execution time from four hours to 15 minutes. I also contributed React features and developed a Node.js and TypeScript live-chat service connecting the website and mobile app.

At LXRandCO, I managed and maintained systems including the ERP, website, POS, and API server, using PHP Laravel and Zend, Docker, Jenkins, and AWS. Earlier, I improved payment and checkout systems at Beyond the Rack and worked on migrating legacy PHP code to Yii at SSENSE.
