• Improved session storage latency in the Auth service by transitioning from Google's datastore to Redis/Memcache, effectively reducing latency from ~300 ms to under 50 ms. • Designed a system for real-time data consumption from web sockets, facilitating the distribution of orders and trade data to multiple consumers. Utilized Redis streams to allow consumers to read data at their own pace. • Wrote a single sign-on (SSO) service for handling authorization across all the services following SOLID principles. • Mentored a fresher, guiding them in the development of production-grade applications aimed at delivering business value with their professional growth. • Generalized file handling for upload of diverse files. This lets developers concentrate solely on the business logic, reducing the time and effort required for integrating new files in database import processes.

Fisdom•  September 2021 - September 2023

• Optimized data processing pipeline by migrating from App Engine Pipelines to MapReduce, reducing request rate on datastore from 2k/sec to 400/sec, and decreasing active instances from 40 to 7, resulting in resource savings. • Transformed a legacy Python 2 service to Python 3, and containerized and made it cloud agnostic. Implemented various optimizations, including transitioning to Flask, asynchronous processing, and reducing mutual fund data processing time from an hour to 15 minutes. • Refactored the mutual fund recommendation feature by simplifying intricate recommendation logic into smaller, readable, maintainable, and extensible code. • Wrote a generic library on top of the Elasticsearch library for internal teams, for integration across multiple microservices.

Software Engineer

Koshex•  July 2021 - September 2021

• Wrote a REST API endpoint that returns data from Redis, leveraged RediSearch for various filters which reduced the response time from seconds to milliseconds. • Worked on the new front-end of the Koshex Website, which included best coding practices in Angular, various REST API integrations, and working with Angular Material. • Integrated Login and signup using Google OAuth on the website.
