• Spearheaded the development of multiple BFF (Backend for Frontend) microservices using Java Spring
Boot, optimizing system architecture and user experience.
• Designed and implemented the Profile BFF, responsible for orchestrating and consolidating data for user profile
pages, enabling seamless functionality and data retrieval.
• Built the Product Description Page (PDP) BFF, managing dynamic product data and improving API response time from avg of 2s to avg of 700ms.
• Leveraged advanced design patterns such as Rule Engine and Chain of Responsibility, enhancing maintainability and scalability of solutions.
• Collaborated with cross-functional teams to ensure integration, performance, and stability of backend services supporting high-traffic systems.

• Successfully worked on transitioning from Monolith (SAP Hybris) to Micro-services (built using Java Spring
• Boot), which resulted in saving 30 million AED per year
• Took ownership of key e-commerce projects like Checkout, Loyalty System and Returns which improved response time for APIs from avg of 2 seconds to 500 ms
• Developed a real-time Inventory Management solution (built using Confluent Kafka) that utilized accurate inventory tracking and intelligent allocation algorithms
• This effort led to a substantial 25% decrease in stock discrepancies, a remarkable 40% reduction in order fulfilment time, and a significant 90% increase in product availability
• Resulting in a notable rise of 10% in sales
• Worked with event streaming platforms like Kafka, and messaging services like Azure Service Bus, Event
• Hubs etc to build scalable applications handling around 100K events per minute
• Developed and Launched Self Service Stock Portal (using ReactJs and Java Springboot) to provide end-to- end visibility to the sales team which results in saving 30% of engineering operational time
• Developed from scratch and took full ownership of both front-end and back-end service for this project
• Built a monitoring and alerting system, using NewRelic for better visibility of order flow, system down- times etc to ensure a healthy and efficient system.

• Designed Rest APIs and implemented features like Single-Sign-On using MSAL and Authentication using Spring Security
• Documented, implemented, tested, and maintained 5+ microservices, ensuring adherence to best practices and achieving a 90% reduction in service downtime incidents
• Conducted rigorous unit testing by developing and writing JUnit test cases, ensuring robustness and reliability of applications by ensuring more than 90% code coverage on Sonar
• Created a Test environment for an end-to-end journey of Inventory Management thus improving Test quality and decreasing error rate by 40%.
