PakistanWhat I'm looking for
At CodeFulcrum, I developed REST APIs and Spring Boot microservices, including B2C features for program-reward associations and cohort competitions. I also automated record insertion through APIs, eliminating spreadsheet uploads and direct database insertions and saving 85% of manual effort.
Previously, at Systems Limited, I worked on billing, cash withdrawal, and e-commerce microservices, including a retailer e-commerce feature that generated an additional 2 million PKR daily in revenue for Oneload. At Postex, I contributed to moving the back-office system from a monolith to microservices and delivered merchant features that reduced the finance team's effort by 40%.
