Sebastian Gug
Senior Software Engineer at Senttr
Cambridge, England, United Kingdom
Summary
👤
SeniorSebastian Gug is a senior software engineer based in Cambridge with over a decade of experience turning startup ideas into scalable, cost-conscious products. He specializes in TypeScript/NodeJS/NestJS, GraphQL, Svelte/SvelteKit and cloud infrastructure (Terraform, Kubernetes, Azure/GCP/AWS), while selectively reaching for lower-level tools like Rust, Elixir and WebAssembly when a product demands it. Sebastian has led secure, highly sensitive projects—building on-premise LLM integrations, sandboxed AI agents, and end-to-end encrypted messaging for government and defence customers—so security and operational resilience are core to his architecture choices. He combines hands-on development with technical leadership, habitually owning API design, CI/CD and multi-cloud deployments, and has a knack for balancing performance with real-world constraints such as staff and cloud cost. An engineer who prefers pragmatic tech selection, he repeatedly delivers resilient systems that scale from prototypes to hundreds of thousands of users.
