• Lead the new Ride Hailing project from the engineering side. Mrsool is building up a ride-hailing vertical to be launched in Riyadh. I helped draft the architecture for the same, decide the tech stack and lead the implementation efforts.
• Lead the RCAs of major incidents across Mrsool and drove the fixes, solutions and reviews of some of them.
• Laid out 3-6 month technical roadmap of the Order Management System and Subscription System.
• Proposed and prepared the architecture of a new Subscription System, which is multi-tenant and scalable.
• Implemented Go-Kit modules for
• resilience (CB, BulkHead, Timeouts) support
• Redis and Kafka event bus clients
• Observability parameters of the above
• Improved the MDM (Metrics, Dashboard, Monitoring) of various modules of Buyers domains.
• Stack: RoR, Golang, Mysql, Redis, Kafka

• I contributed to and optimized Flink pipelines, mentored multiple engineers, and briefly led the ML Platform team, designing pipelines for feature movement across ML models and working with Qdrant for vector embeddings of products and catalogs.
• I designed the Server Driven UI (SDUI) framework for the customer app, collaborating closely with Android and iOS teams to define generic, forward and backward-compatible contracts, and to architect a robust backend foundation.
• I’ve played a key role in designing and implementing large-scale services using GraphQL, Project Reactor, and Spring Boot Reactive. One of my major contributions was conceptualizing and independently building a high-performance Network Library Interface for Executors and Clients with JPA-like features, supporting both reactive and non-reactive REST and gRPC calls. This required deep understanding of design patterns and API design principles.
• I implemented Executor interfaces for Resilience4J and Hystrix, and Client interfaces for WebClient, Apache HttpClient, and gRPC. These interfaces offered significant advantages — separation of business logic from network code, reduced boilerplate, improved developer efficiency, abstraction from low-level third-party dependencies, and built-in resilience patterns for calls to databases, Redis (far caches), REST services, and more.
• As SDE-4 and Tech Lead for the Shopping Platform team, I led the design and optimization of feed aggregators across real estate modules such as Homepage, Search, ForYou, and Listing within the Meesho app. I drove cost-optimization, implemented Rx-based feed aggregators using Project Reactor and the network library, and established comprehensive monitoring, alerting, and documentation systems.
• Tech Stack: Java, RxJava, Project Reactor, Golang, Kafka, Flink, HBase, GraphQL, MySQL, gRPC, Databricks, Python, Notebooks.

• During my tenure at Paytm Mall, I made significant contributions in both the Facilities On-Boarding and the Serviceability Team.
• In Facilities On-Boarding, I played a key role in developing REST APIs, including one for generating invoices, and worked on consignment validation and the migration of UI from AngularJS+ReactJS to ReactJS. I heavily contributed towards the effort of migrating NodeJS REST APIs to Java Rest APIs.
• In the Serviceability Team, I developed data pipelines to synchronize data across various databases like, Aerospike, MYSQL, ElasticSearch using Kafka, Maxwell’s Deamon, and my work laid the foundation for efficient data management and visualization. Overall, my time at Paytm Mall allowed me to enhance my development skills and make meaningful contributions to the organization's growth.
