Senior .NET Engineer
I build distributed systems that survive production.
Specializing in high-throughput microservices, resilient sagas, and zero-downtime infrastructure. Currently based in London.
Evidence
A live .NET 9 cluster, running in your browser.
This isn't a mock. Trigger a checkout to see a real MassTransit saga state machine orchestrate across four microservices. Click 'Inject Fault' to see the cluster automatically compensate.

Each row is one message — direct HTTP at the top, RabbitMQ events between services after that. No central transaction.

Architecture
Patterns for scale and reliability.
Detailed breakdowns of the decisions that define the platform. Focusing on how we handle distributed state, data consistency, and failure at scale.
Saga vs Two-Phase Commit
When you can have ACID across services, when you cannot, and why the answer in 2026 is almost always sagas.
The Transactional Outbox
Why dual-write is the most expensive bug in event-driven systems, and the small amount of plumbing that fixes it forever.
Zero-Downtime Secret Rotation
How we rotate database credentials and API keys in a live distributed system without dropping a single request.
