I’m a software engineer who designs and delivers .NET applications for workflow and document management, focusing on automation that reduces manual work. At Farfetch, I build and maintain services in the Buy Flow, a business-critical purchase pipeline where reliability matters.

I architect secure, scalable .NET Core services using C#, Entity Framework, JWT, CQRS/MediatR, and REST APIs (Swagger). I collaborate with stakeholders to gather requirements, prioritize backlogs with Jira/Kanban, and coordinate releases for consistent multi-environment deployments.

I’m serious about engineering quality: I apply SOLID principles, design patterns, and TDD with xUnit/FluentAssertions, and I refactor legacy systems to support migration to modern .NET Core. I ensure API reliability through functional testing with Postman, automate regression coverage, mentor developers through onboarding and code reviews, and work with cloud and resilience practices (Azure services, Docker/Kubernetes, circuit breaker, exponential backoff, rate limiting) to keep systems stable.
