Java Spring Boot, handling high-volume financial transactions and customer data processing.
• Designed and implemented RESTful APIs to support secure and efficient communication between services and
external systems.
• Implemented asynchronous, event-driven communication using Apache Kafka, enabling loose coupling
between services and improving scalability, fault tolerance, and system resilience.
• Participated in designing data flow and event schemas, ensuring reliable message delivery and consistency
across distributed components.
• Developed comprehensive unit and integration tests using JUnit, improving code reliability and reducing
production defects.
• Played a key role in the migration of 4+ million customers with zero downtime, ensuring data integrity,
consistency, and smooth system transition.
• Collaborated in debugging and performance tuning of services, optimizing response times and handling high
concurrency scenarios.
• Project: Loan Origination System (Al Rajhi Bank)
• Developed and maintained backend services using Java Spring Boot, supporting the full lifecycle of loan
applications from submission to approval.
• Designed and consumed REST APIs for seamless integration with internal systems and third-party services.
• Built and enhanced frontend components using JavaScript, improving user interaction and workflow efficiency.
• Worked with SQL Server to design queries and manage transactional data, ensuring consistency and performance
in financial operations.
• Integrated with Newgen platform for business process management and document handling within loan
workflows.
• Collaborated with cross-functional teams (business analysts, QA, and DevOps) to deliver secure, scalable, and
compliant financial solutions.
• Used Git for version control and participated in code reviews, ensuring maintainability and high code quality.

• Developed and deployed a full-stack HPC (High-Performance Computing) request management system enabling
researchers to submit, track, and manage computationaljobs on the BA supercomputing cluster.
• Designed and implemented backend services using Laravel (PHP) with RESTful APIs to handle job requests, user
authentication, and workflow management.
• Built an interactive and responsive frontend using Vue 3, improving usability and streamlining the request submission
and monitoring process.
• Contributed to optimizing workflow efficiency for research applications such as data analysis, simulations, and scientific
computing, leveraging BAs HPC infrastructure.
• Implemented role-based access control and validation mechanisms to ensure secure and reliable system usage.
• Collaborated with cross-functional teams to gather requirements and deliver a scalable solution aligned with research
needs.
