Backend Development, Java, AWS, Azure, GCP, iPhone Apps, Android Apps.
I am Udit Agarwal. I am a Technology Enthusiast and currently working as an Engineering Leader in the Backend. I have been working in the industry for quite some time now and I have most of my experience in designing and scaling Backend Systems. Have worked with companies like Microsoft, Adobe, Amazon, and Directi. Each company gave me an opportunity to work on various types of high throughput systems like chat applications, e-commerce, cloud file systems, streaming systems, etc.
With every product, I faced different challenges which taught me how to design the right systems using different technologies for the given problem. I have a sound knowledge of Java, DynamoDB, SQL, Caching technologies like Redis, and Queuing systems like SQS, Kafka, etc. I graduated from IIIT Allahabad in 2013.

Led the core catalog backend team of Xbox. Handled the end-to-end catalog including product ingestion, indexing and then finally service it to users.
Biggest challenge was to handle huge QPS of 100k within single digit latency and that also in the most cost-effective manner. We were mostly using azure services like Service fabric for orchestration, AFD for routing, Azure cognitive search for search indexing, CosmosDB for data, and many other services for other various purposes.

Drove core backend features of Adobe Cloud Platform. The team was responsible for providing cloud infrastructure for various Adobe products. Re-architected complete application from a monolithic service into microservices to improve resiliency, availability. This also enabled us to deliver more features at even faster speed.
Worked on services for providing asset storage, events, notifications, sync across clients, access controls, search, etc. Used DynamoDB for our entities database. S3 for blob store. SNS for sending notifications to clients. Services are containerized using Docker. Orchestration is done using internally available service Ethos. Using NewRelic for metrics and alarms, Splunk for logging.
