What I'm looking for

I’m looking to build .NET microservices and event-driven backends where reliability matters. I want to collaborate with product, QA, and DevOps to deliver maintainable systems, improve resilience, and own end-to-end engineering from design to testing.

I’m a Senior .NET Engineer with 9+ years of experience building .NET-based backend, web, and full-stack systems across fintech, SaaS, B2B platforms, workload automation, and banking domains. I focus on distributed, production-ready architecture—turning complex workflows into clean .NET/C# services with strong reliability, observability, and maintainability.

Across my roles, I design and implement backend services (Web API, MVC, microservices), data layers (PostgreSQL/SQL Server/MySQL, Entity Framework/EF Core), and messaging/event flows (Kafka, Redis, Azure Service Bus). I’ve delivered enterprise features—API changes, audit/history, role/permission workflows, and customer-facing production fixes—while improving quality with xUnit, Moq, AutoFixture, and FluentAssertions through unit and integration testing.

I also enjoy the “glue work” that makes systems scale: Kafka-based event contracts, shared client packages, retry/resilience mechanisms, background workers, and integration pipelines used across multiple services. From Docker/Kubernetes and Azure DevOps CI/CD to code reviews and architecture collaboration with product, QA, DevOps, and cross-functional teams, I bring a pragmatic engineering mindset: ship reliably, document integration paths clearly, and keep systems easy to evolve.
