Stack

Full stack, with the back end as home.

Day to day
C# and .NET on the server, TypeScript and React in front of it.
Data
Postgres, MSSQL and Redis — schemas, migrations, and the occasional query plan.
Distributed
Service Bus, Kafka and SQS. Queues, retries, and making things idempotent.
Cloud
AWS by preference, Azure by experience. Docker and GitHub Actions around both.
Lately
Agentic tooling, RAG, and running small open models locally.

Mostly I believe in picking the right tool for the job.

Play

Mostly evenings and weekends. All of it is on GitHub.
