Rockstar🎓
Top SchoolSamuel Zislis-gaus is a Technical Lead based in Edinburgh with 15 years of experience building and scaling full-stack web products and engineering teams. He blends hands-on expertise in Node.js, TypeScript/React frontends and Python backends with a strong emphasis on security, having fixed critical JWT parsing vulnerabilities in the widely used Rasa open-source conversational AI project. At Rasa he grew a solo frontend capability into a dozen-strong team, created design systems and led cross-squad engineering, hire/onboarding and interview processes. He has led architecture and delivery for ML-driven microservices and SPAs, and brings practical DevOps and deployment overhauls to bear on performance and testing challenges. Samuel pairs technical leadership with frequent pair-programming and mentorship, preferring to solve the hardest engineering problems alongside his teams. Outside standard career arcs he once briefly swapped code delivery for delivering takeaway food — a small reminder he values exercise and pragmatic life balance.
