Lead the full delivery lifecycle of enterprise-grade Java services, from architecture and estimation through production support, for systems serving over 1M requests per day. Drive architectural decisions across teams — layered service boundaries, domain-driven modelling, and event-driven integration — keeping the codebase modular and independently deployable. Modernised a legacy platform onto AWS, adopting serverless and managed services and introducing Node.js and React alongside the Java core; improved scalability and cut delivery time for new features by ~30%.

Designed and optimised CI/CD pipelines with automated tests, static analysis, and containerised builds, reducing release cycles from days to under an hour and removing manual deployment steps. Mentor engineers through code review and design sessions; own the team's coding and testing standards. Work directly with Product, DevOps, and QA stakeholders, translating business requirements into technical plans and explaining trade-offs to non-technical audiences.

Owned end-to-end development of Spring Boot microservices running core business operations in Agile teams, sustaining 99.9% uptime under production load. Modelled domains and service boundaries, replacing synchronous coupling with event-driven messaging over

Kafka and ActiveMQ to isolate failures and improve resilience. Introduced profiling-driven algorithm and query optimisations across SQL and NoSQL stores, cutting processing time by ~40%.

Raised engineering standards through code reviews and integration testing with JUnit, Mockito and

Testcontainers; mentored junior engineers. Hardened backend security: authentication, authorisation, input validation, and secret management.

Delivered Spring Boot and Micronaut backends with RESTful APIs for international clients, from requirements through to deployment and support. Ran architecture and code reviews, resolved complex production defects, and tuned system performance. Advised clients directly on pragmatic, cost-effective technical solutions — sustaining long-running client relationships and repeat contracts alongside full-time roles.
