Dimitrios Kanellopoulos is a seasoned Full Stack Engineer with 14+ years of experience building web and sports-data platforms, currently working remotely from Amsterdam. He blends frontend expertise in Angular, TypeScript and JS with backend and infrastructure skills in Python, PHP, Node.js and cloud services (AWS, GAE, Firebase), and has shipped a quantified-self analytics app that processes FIT activity data. A pragmatic team lead and hands-on developer, he has moved between roles from delivery manager to Android developer and maintained high discipline in remote collaboration using Agile and Slack. He contributes to open-source projects—improving security-critical OAuth flows in the Facebook PHP SDK—and prefers work that pairs infrastructure, data and realtime UIs. Early exposure to languages like Pascal and assembly informs his low-level curiosity, evidenced by custom watchfaces and server tooling alongside production systems.
