Backend Engineer at Silverspace building cloud-native microservices and secure REST APIs with Node.js, TypeScript, and AWS.

Message

At Silverspace, I architect cloud-native microservices and REST APIs with Node.js and TypeScript, breaking coupled workflows into independently deployable services.

I’ve improved transactional services with PostgreSQL schema and query optimisation, Apache Kafka, and Redis caching. I’ve also automated releases to AWS and provisioned Kubernetes environments with Docker, Terraform, and Amazon EKS.

At Silverspace, I secure customer-facing endpoints with JWT, OAuth 2.0, and role-based access control, and instrument services with OpenTelemetry, Prometheus, and CloudWatch.

Earlier, I developed Node.js APIs as a Backend Developer – Intern at Vizva Consultancy Services and delivered Java and Spring Boot modules as an Associate Engineer at Capgemini. I also designed a lab queue management application and implemented restaurant ordering and reservation modules for projects at Swansea University.
