Experience
Celigo | Hyderabad June 2022 - Present
• Designed LLD to replicate MongoDB (400+ unique complex queries including recursive populate) and Amazon
SQS for the entire core logic of the company. This implementation allowed users to operate in test mode to test
their business flows without using external services or altering original data.
• To combat over-fetching, implemented GraphQL for key endpoints. This resulted in a 30% reduction in response
time and a 90% decrease in downloaded data, significantly improving user experience and resource efficiency.
• Deleted thousands of duplicate resources customers were having by fetching the data with Pandas script on
Snowflake and deleting it via DB migration script. This helped in freeing up memory and resolving the customers
duplicate resource issue.
• Developed multiple REST APIs routes and provided end-to-end testing with Jenkins and Mocha test cases.
• Develop company’s marketplace API where documents of multiple MongoDB models were displayed. Created an
in-house algorithm to combine multiple models that can support pagination, sorting, limit, and aggregation.
• Supported company’s Microservice journey by shifting the code and monitoring the ArgoCD.
