Senior Software Engineer
KASTI build KAST's websites and web app in TypeScript and Next.js on Cloudflare, taking each from Figma through to production. Performance, SEO and third-party integrations are part of the job, not extras.
Behind them I build the lightweight backend services and data pipelines that connect the products to the rest of the business, and look after analytics across the app and websites.
I also build internal tools, such as notification systems and retrieval (RAG) pipelines for AI features.
