What I'm looking for

I seek engineering roles that let me modernise legacy systems, design scalable microservices, and lead cloud-native, cross-functional projects.

I am a full-stack engineer with 12 years of experience delivering robust applications across finance, healthcare, and automotive sectors. I specialise in JavaScript/TypeScript, Node.js, Java, and Spring Boot, building end-to-end systems from design to production.

At Element5 I designed and led an Automation-as-a-Service platform for healthcare, trained AI agents and a local small LLM, and reduced manual workflows by 15%. I build CI/CD pipelines, deploy on AWS, and create React.js frontends integrated with REST APIs.

Previously, I migrated legacy mainframe systems to modern Java + Spring Boot + Angular stacks at Fidelity, implemented microservice modules with Kafka and SFTP, and deployed solutions on Kubernetes with Jenkins. At Infosys I maintained and migrated customer financing systems and integrated with Siebel and SAP.

I prioritise engineering standards, cost-effective cloud architectures, and fault-tolerant integrations. I enjoy collaborating with cross-functional teams to modernise complex systems and deliver scalable, production-ready software.
