About

Java Backend Developer with strong foundations in Core Java and SQL, and hands-on experience building REST APIs with Spring Boot, Spring MVC, and Hibernate — including a production dashboard (Oct 2025 – Feb 2026) serving real client data, and an independently designed backend system (TaskFlow) covering JWT authentication, RBAC, and relational database design. Background in software testing and process automation adds a strong grounding in business logic, edge cases, and quality standards. Looking to bring this combination of backend engineering skill and QA rigor to a Java development team.

Work Experience

Software Tester & RPA Developer

Aug 2022 - Present

Backend development responsibilities since Oct 2025. Built and exposed REST APIs using Spring Boot and Spring Data JPA to fetch process execution data from a PostgreSQL database, consumed by a live monitoring dashboard. Learned and applied Spring Boot, Spring MVC, and Hibernate concepts on the job, translating them directly into working production code within a 5-month build cycle. Designed the data retrieval layer with custom JPQL queries to surface process execution status, run times, and outcomes. Structured REST API responses to meet real frontend data requirements, gaining practical experience in API contract design. Developed and maintained robotic process automation workflows using Java and Selenium, automating repetitive business processes. Reduced manual effort and improved process reliability by automating end-to-end business workflows. Partnered with cross-functional teams to identify and prioritise processes suitable for automation. Translated business requirements into detailed test scenarios validating application functionality. Collaborated with developers and business teams to verify workflows aligned with expected business processes. Tracked and resolved defects using Jira, maintaining quality standards across releases — experience that now informs a strong eye for edge cases in the backend code I write.
