Senior Java engineer with 10 years of experience building, enhancing, and supporting business-critical enterprise applications, with strong domain exposure in banking and financial services.

My core strengths include Java, Spring Boot, Microservices, REST APIs, Oracle SQL, production support, root-cause analysis, and Agile delivery. I have worked across the full software lifecycle—from requirement analysis and solution design to development, testing, release support, incident investigation, and production stabilisation.

I also have prior international onsite assignment experience in Europe, working in a global client environment. I am currently exploring senior backend opportunities where my banking-domain knowledge and Java engineering experience can contribute to large-scale platforms.

• 10 years of enterprise Java engineering experience
• Strong hands-on experience with Spring Boot, REST APIs, and microservices
• Banking and financial-services domain experience
• Experience supporting high-availability and business-critical applications
• Ownership of production issues from investigation through verified resolution
• Practical experience maintaining both legacy and modern Java systems
• Collaboration with business, onsite, QA, support, and engineering stakeholders
• International onsite experience in Europe
• Focus on maintainable code, reliable APIs, test coverage, and safe releases

• Production-grade Spring Boot microservices
• Event-driven architecture with Apache Kafka
• Docker, Kubernetes, and cloud-native Java
• System design for scalable backend platforms
• Secure REST APIs and authentication/authorisation
• Generative AI and LLM integration with Java
• Automation for enterprise engineering workflows

I am open to employer-sponsored relocation and work-permit opportunities for senior Java/backend roles.

Target markets: Singapore · UAE · Ireland · Germany · UK · Canada
Target roles: Senior Java Engineer · Lead Java Developer · Backend Engineer · Microservices Engineer · Technical Lead
Industry strengths: Banking · Financial Services · Enterprise Platforms

I am particularly interested in teams building payments, banking platforms, transaction systems, APIs, microservices, event-driven services, and high-availability backend systems.

I am actively building recruiter-ready projects that demonstrate:

1. Spring Boot microservices with service discovery, resilience, and API gateway patterns
2. Event-driven processing with Java and Apache Kafka
3. Secure REST APIs with authentication, authorisation, tests, and documentation
4. Production-ready observability, resilience, and troubleshooting patterns
5. Java AI/LLM integration for practical enterprise workflows

• Spring Boot Microservices — Java/Spring Boot microservices samples with REST endpoints, integration testing, Maven CI, CodeQL analysis, and contributor guidance.
• Spring Boot Kafka — Kafka producer/consumer examples with production-readiness guidance for retries, dead-letter topics, monitoring, and incident triage.
• Spring Boot PostgreSQL — Spring Data JPA and PostgreSQL reference with a repeatable local Docker Compose setup.
• REST API Documentation — Practical REST conventions, error-response standards, and HTTP status-code guidance.
