Senior Full-Stack Engineer

Adam Drąg

I build agentic AI, the usage-based billing that monetises it, and the cloud it runs on - then cut the bill 25%.

Eleven years in, now one of two core engineers at a venture-backed startup - I own nine production services end to end, from the React frontend down to the distributed systems on AWS behind them. I work across TypeScript, Python and Java, and I care about what things cost to run. Based in Banya, Queensland.

What I focus on
01

AI systems

Agentic loops, RAG, prompt engineering and LLM cost modelling on AWS Bedrock - shipped to production and priced so it pays for itself.

02

Cloud & infrastructure

ECS Fargate, Lambda and AWS CDK, multi-arch container builds and hands-on FinOps - recently cutting AWS spend 25% and moving the production fleet to ARM64 Graviton.

03

Full-stack product

React 19 and GraphQL federation, local-first sync and Stripe billing - owning features from the frontend down to the distributed systems behind them.
