Universal Card Enrollment

Encryption | Software security | Scalability

Leading development of a service that converts your visa card to a non-sensitive unique string which can be used with non-transactional visa services, without worrying about your card getting hacked over network or from disk.

Traffic - ~10k hits per hour and growing.

Realtime Linking - Building big data based applications to enable real time card enrollment and spend assessment. These applications output interchange(what proportion of your transaction goes to your bank) for every visa card in the world.

◦ Developed a data pipeline that estimated the life span of a laser to enable efficient inventory planning ◦ As a part of the pipeline, developed a highly responsive GUI tool that automated ETL tasks. The tool was adapted by multiple teams. ◦ The model was able to perform with a BER of 0.76 using SVMs, with the dataset having an imbalance of 70:30. Used Python, specifically SKLearn, Matplotlib and Keras for implementation and visualization.

Worked on developing data pipelines, data modeling and visualization.

Used Python, Spark, Tableau and DB2 SQL.
