Top SchoolPhilip Tietjen is a Senior Software Engineer with a decade of experience building full-stack web applications across e-commerce, media, and fintech. He specializes in Node.js and React (including Next.js, TypeScript, and modern state libraries), with a strong track record of shipping server-side rendering, REST APIs, and performance-focused frontends. Philip has driven architectural improvements and testing culture at organizations like CBC and Finaeo, leading hackathon projects, refactors to React hooks, and TDD adoption with Jest and React Testing Library. At LabX he led a multi-vendor ecommerce build and maintained CI/CD pipelines, and at Upgrade he continues to apply that blend of product-minded engineering and operational ownership. Colleagues know him for tackling legacy tech debt pragmatically while championing measurable web performance and role-based auth integrations. Based in Ontario, he pairs hands-on coding with hiring and interview experience, making him equally comfortable mentoring teammates and shipping features.
