Project history
Consultant from UST working for Capital One Bank. Led a distributed team of 9 engineers across UK and Spain delivering scalable backend microservices for 4.5M+ daily users. Designed and executed the migration from on-premise services to AWS cloud, leveraging Java Spring Boot, Docker, and event-driven REST architectures. Defined and implemented CI/CD pipelines, improved deployment reliability, and integrated AWS Secrets Manager for secure configuration management. Oversaw performance tuning, architectural design, and team mentoring within an Agile/Scrum framework.
Analysed project requirements and implemented them in the spacecraft simulator to ensure alignment with mission objectives. Authored comprehensive project documentation adhering to ECSS standards for quality and compliance. Developed and deployed the spacecraft simulator in C++ and Java within a containerised environment, ensuring scalability and reliability. Conducted technical project meetings with the European Space Agency to monitor project status, report progress, and ensure timely deliverables. Utilised Podman, Maven, and Kubernetes to create containerised applications for efficient simulation run.
Developed interactive web interfaces using TypeScript, Angular, RxJS, and SCSS. Optimised PostgreSQL queries and stored procedures to improve application performance. Designed, built, tested, and deployed applications following Agile methodology. Developed user authentication REST APIs using Java Spring Boot. Created and maintained APIs using Django REST Framework and PostgreSQL. Implemented CI/CD pipelines with Jenkins to automate deployments across environments. Managed Agile projects in Jira, tracking progress, organising tasks, and planning sprints.
