Vassilis Katsaris is a principal software architect based in Athens with over a decade of experience building resilient, high-concurrency web and mobile applications. He spans the full stack—front-end frameworks like Nuxt/Vue and React (including React Native) to back-end stacks such as MEAN, Node.js, MySQL/MongoDB—and emphasizes architectures that scale under increasing traffic. Skilled in messaging and real-time systems, he leverages RabbitMQ, Redis, and Socket.io alongside web workers to deliver robust, low-latency solutions. He also brings practical experience in hybrid mobile tooling (PhoneGap/Ionic) and pragmatic web design, blending growth-hacking sensibilities with engineering rigor. Known for shipping production-ready systems, he focuses on durability and maintainability rather than one-off prototypes.
