I am currently a senior software developer working in payments gateway team in Paytm which is India`s biggest payment gateway and handles around 20 Million transactions per day and can support around 4 thousand transactions per second. I was involved in a major functionality migration of the system and also re-structuring the thread pool in the system. previously I worked with one of the biggest and oldest Telecom industry Bharti Airtel and was working in X-Labs and was responsible for all the activation on prepaid sim cards and also I was responsible for introducing the new framework Airflow to automate the task. I also single-handedly created the utility which submits the data to India`s Department of Telecom. This utility saved around 40 Crore Rupees annually. Before this, I also worked in HT-Media india`s leading newspaper company as a software developer. Technology stack which I used till now: Python Java CPP and frameworks Spring Django Airflow ©
