What I'm looking for

I seek senior backend/Java roles designing scalable, highly available systems on AWS, working in Agile teams to solve high-throughput problems, drive architectural improvements, and deliver measurable business impact in financial or enterprise domains.

I am a software developer with 5+ years building robust, high-throughput systems for financial and enterprise customers using Java, C# and microservices. I focus on high availability, performance tuning and maintainability while contributing across the full SDLC.

I have architected and implemented solutions that handled hundreds of thousands of transactions per minute, transformed manual workflows into digital processes (including digital account opening and automated document flows), and improved performance and scalability through message brokers, caching and targeted refactors. I routinely use AWS services, Datadog monitoring, RESTful APIs and design patterns to ensure resilience and observability.

I hold Oracle and AWS training/certifications and a postgraduate diploma in Software Architecture, and I thrive in Agile teams where I can drive architectural improvements, mentor peers, and deliver measurable business impact.
