- Integrate LLMs (Gemini and others) into the product in a measurable, monitored, production-safe way
- Build reliability foundations: monitoring, logging, retries, runbooks
- Own features end-to-end — from vague brief to production
Must-haves:
- Strong NodeJS + NestJS + GraphQL + PostgreSQL
- Hands-on with LLMs in production (Gemini a plus)
- Event-driven architecture, Prisma, Terraform
- Reliability mindset: monitoring, QA, retries
Format:
- ~100% freelance via Shakers

- ~ Hybrid in London - flexible (EU timezone)
If you're AI-native in practice and want real end-to-end ownership in a high-taste studio, apply.
