Senior software engineer specializing in scalable Java microservices.
What I'm looking for
I am a dedicated software engineer with extensive experience designing, developing, and deploying scalable, reliable systems across health, finance, education, traffic enforcement, and transportation sectors. I have led migrations, built critical microservices, and implemented cloud-native solutions using Java, Kotlin, Spring Framework, Kubernetes, and related technologies.
Throughout my career I have driven projects that improved system performance, reduced costs, and enhanced user experiences — including booking and payment portals, GP and patient apps, and centralized lookup services — while mentoring junior engineers and championing best practices in testing, automation, and infrastructure as code.
