About

As a Software Engineer at Tekion Corp, I work on developing new products for multiple dealerships who have partnered with Tekion, using technologies like DynamoDB, Mongo, Spring, Kafka, Aerospike, and Elasticsearch. I have contributed to consumer-facing products, enhancing their backend and scalability, and understanding the requirements of dealerships and delivering them their own digital retailing support. I am also working on an MVP product that would enable them to independently add enhancements to their current applications without external support from Tekion. I graduated from Birla Institute of Technology and Science, Pilani, with a Bachelor of Engineering degree in Computer Science in 2022. I have a passion for coding and problem-solving, and I have participated in several competitive programming contests, such as ICPC Regionals in 2021 and 2022, and Codeforces, where I have a purple rating. I have also interned at Walmart Global Tech India. Additionally, I have been involved in the Coding Club at BITS Pilani, where I served as the Ex-Joint Secretary.
