Professional Experience
UKG (Kronos Solutions India PVT LTD)
Sr. ARCHITECT (Jan. 2022 ~ PRESENT)
Role
Working as senior architect on the modernization of a world-leading workforce management software suite. Working closely with Engineering leadership, product, and UX teams in the USA, India, and Canada to finalize requirements, architecture, design, and POC/Prototype development. I am also working very closely with the development teams and regularly review to ensure all correct development stacks, patterns, and tools are used to create performant and quality products.
Project: Modernization of UKG integration and Suit
Development of cloud-based services to significantly reduce onboarding time for small and mid-sized customers, while delivering a seamless customer experience at UKG. These services were designed to integrate UKG services with third-party platforms using the Boomi integration platform’s iPack feature.
Designed and implemented a robust and flexible web service that allowed customers to import and export data using customizable configuration templates. These templates facilitated data validation and posting to UKG product’s REST APIs, ensuring data accuracy and compliance with specified formats.
In addition to my primary responsibilities, I initiated a crucial security-strengthening initiative aimed at enhancing the security of sensitive information. The initiative involved migrating all secrets to Google Secrets Manager and implementing an automated rotation and dynamic swapping mechanism for credentials used by backing services such as databases, message queues, and caching systems. Notably, this mechanism allowed for seamless rotation and swapping of credentials without the need to restart pods. To achieve this, I designed and successfully executed a proof of concept (POC) for Spring Boot-based services, which served as the foundation for a standardized secrets rotation and hot swapping pattern adopted throughout the entire company. For this, we used “dual user” approach for a seamless rotation and swapping process.
