- Worked with breaking down monolith application and rewrite in multiple microservices focusing on Scalability, Availability, Data Resilience, Security & Observability. Technology used: Spring Boot, MinIO Object Storage, Apache Pulsar, Aerospike(distributed caching), Prometheus etc.- Worked heavily configuring and integrating microservices with Kubernetes and Helm. Work includes: containerized applications with Docker, configure and deploy the application to multiple environments, HTTPS and certificate configuration and management automation.- Facilitate services to be production-ready by finding performance bottleneck on serving requests, thread pool optimization, setting up logging level dynamically etc. Used profiling tools like VisualVM, JDK Mission Control and optimized code to make application faster.

Worked with multiple teams including the Mobile Platform team & Driver app team. Grab has multiple applications and is being used by more than a million users every day and very extensively. The role of the Mobile Platform team is to define and drive common mobile architecture and methodologies across the mobile application team. Also, solve the common and critical scaling problem faced by a different team.Key achievement:- Initiate an in-house product: an SDK for analytics, logging, monitoring, and crash incident recording to improve user experience and debug critical production issues. First developed as MVP; then iterate over to a fully working product used by all applications in Grab. This in-house product reduces cost around 600-700K by removing a 3rd party dependency. Also, this solves a lot of data inconsistent problem.- Initiate and developed another in-house SDK with Android NDK to detect security threats, including detecting app modification, device tampering, bad URLs, potentially harmful apps, and fake users. Later it was adopted and maintained by a separate security team.- Develop an integration framework where a component can be developed in a non-native platform, like React, Flutter, Web and then can be integrated seamlessly with Native main application.
