Top SchoolPandelis Zembashis is a CTO and seasoned software leader with a decade of experience building scalable, event-driven systems and cloud-native platforms across startups and growth-stage companies. He has led engineering and product-aligned greenfield projects—from IoT and electric mobility to high-performance e‑commerce and email hyperscaling—working hands-on with Go, Python, TypeScript, React, GraphQL and serverless architectures. At Cosine he’s focused on advancing AI-driven developer tooling, and previously helped scale core infrastructure and onboarding at 11x.ai and Weezy (acquired by Getir). Known for improving developer workflows and observability, he routinely architects migrations (ECS→Lambda), search and real‑time systems, and platform integrations. Based in London, he pairs pragmatic engineering with team-building to ship production software fast, and his playful GitHub and LinkedIn bios hint at a creative, curious approach to problem solving beyond conventional résumés.
