Created highly scalable products in Product API team which develops services which renders information about a product when it is scanned at Tesco stores. Serves 900K RPM traffic with P99 being very low at around 30ms.
Re-Designed Groupings/Promotions Service to address 10k product promotion group creation in a day with P99 < 200ms. With optimized code, several JDBC connection errors, and high CPU & memory leak issues were fixed.
Converted a Monolithic Inventory service that processes the product updates from various source systems based on fixed timings into multiple source system-specific Microservices that act upon their respective Kafka events. Latest Springboot & Java21 features including virtual threads are used.
Built a new light weight application in Micronaut using SQLite to return product data when scanned on TILLS of UK. This resulted in 2x improvement in performance and memory footprint halved.
Built a platform library to generate query DSL based on input filters to search product data in Couchbase DB.
