What I'm looking for

I’m looking for a senior backend role where I can design reliable event-driven microservices in distributed systems, improve observability and incident response, and mentor teams—ideally in payments, identity, or other high-stakes domains.

I’m a Senior .NET Backend Engineer with 8+ years building event-driven microservices for high-stakes financial systems. My focus is distributed systems reliability—where correctness, resilience, and observability matter.

At Dell Technologies, I’ve spent 4+ years on payment transaction and authorization platforms. I designed idempotent retry workflows, Kafka-driven pipelines, and DLQ-based failure handling to reduce manual reprocessing of failed transactions.

I also built observability and troubleshooting solutions using Splunk, including structured logging and dashboards for throughput and error rates—cutting incident resolution time. Alongside this, I support production reliability through diagnosis and resolution of distributed-system issues while maintaining high availability.

I bring a strong code review and mentorship culture, partnering with Product Owners during backlog refinement in Agile/Scrum to improve delivery predictability. With an MBA in Software Architecture, I’m especially motivated by architectures that map cleanly to real-world money movement, auth flows, and event-driven reliability.
