What I'm looking for

I’m looking for senior engineering opportunities where I can lead microservices modernization and platform modernisation, improve reliability and performance, and deliver cloud-based business transformation at scale with strong technical mentorship and quality standards.

I’m a Senior Software Engineer with 6 years of strategic technical leadership, transforming legacy systems into scalable microservices architectures for Fortune 500 financial institutions. I’ve led end-to-end platform modernisation initiatives—reducing system complexity while improving operational resilience and business agility for mission-critical applications.

I architect high-throughput financial transaction systems processing millions of operations daily with guaranteed reliability and sub-millisecond latency performance. I also drive cloud migration and platform quality through AWS-based deployments, CI/CD automation, observability with Splunk, and technical mentorship that strengthens engineering standards across distributed teams.
