Maintenance of legacy codebase, improving performance and implementing new features.
Collaborated with a dynamic team of 12 Human Resource Analysts to develop robust human resource applications providing significant value to the business and resulting in several key new customers. • Built and delivered robust WEB APIs for seamless data transfer and integrations into external systems using c# .Net 6 and Microsoft Azure services. • Drove a significant reduction in the specific complaints related to functionality and infrastructure in a legacy codebase, bringing it down by over 30%. This achievement greatly eased the workload of the back-office team, enhancing their efficiency and productivity. • Incorporated security best practices in application development, leading to a 50% decrease in security incidents. • Applied class-based controller-service-database pattern in designing APIs to accommodate current feature changes and future changes. • Enhanced legacy codebase by implementing Retry pattern, Circuit Breaker Pattern, Cache­Aside Pattern to enable maintenance of existing features and provision for new features to be added. This contribution played a pivotal role in enhancing the efficiency of the system, leading to a 25% increase in service usage, attracted new users, generating an additional revenue. • Introduced Azure testing frameworks, improving code quality and reducing bug occurrence by 40%. • Applied logging and telemetry to development detect performance anomalies and application usage. • Designed Service Level Objective, documentation and refactored a monolithic code base architecture to create a better developer experience
