- Designed Blue Green Canary stack in Atlas: Designed & demonstrated Blue green implementation and set an example for zero downtime deployment.
- Authorization Algorithm: Architected, designed, and implemented a robust Authorization algorithm that is an in-house solution for compressing hundreds of permissions into a small chunk of characters that cannot be decoded without the algorithm, made the API secure from TAAP, and created an in- house Authorization algorithm. This adds a security layer atop TAAP, and by doing so, Atlas was able to address adding permission dynamically.
- Streaming API: Designed and built a streaming API that reduced network calls for Memo retrievals by a quarter, resulting in a lighter API and fewer UI interactions.
- TAAP implementation: First application to onboard to TAAP application and demonstrate across Technology org.
