I build reliablesystems behind useful products.
Full-stack Software Engineer with a strong backend focus, building reliable enterprise systems with C#/.NET and React. 6+ years working across REST APIs, microservices, integrations, asynchronous processing, event-driven systems, and containerized deployments with Docker.
02About
Complex business rules, turned into services that don't surprise anyone.
For six years I've worked on enterprise platforms used every day inside large retail and service organisations — workflow automation, customer service ticketing, internal communication. My part sits where the logic is heaviest: approvals, permissions, integrations, and the queues and workers behind them.
01
Design for failure first
Retry, rollback and error tracking are part of the feature, not an afterthought.
02
Decouple with queues
Heavy work belongs in a worker, never in the user's request.
03
Measure before optimising
Batch processing and preloaded lookups beat clever code.

07How I build systems
The API answers fast. Everything expensive moves to a queue.
Workers do the heavy lifting — bulk operations, Excel processing, exports, notifications, scheduled jobs — and the user hears back over SignalR the moment it's done.
