Our client was a fintech firm that launched a game changing credit card payments and rewards platform for millions of users. An optimized fintech stack for more than 10 million users’ credit card data required regulatory compliance, data engineering capabilities, robust backend operations and swift customer support. 91social helped build a PCI-DSS store that held the sensitive masked credit card data of our client’s users.
The server component of the PCI-DSS store used an AES algorithm and an AES key length of 256 bits to encrypt the plaintext card numbers plus AWS Key Management Service giving centralized control over cryptographic keys database. Subsequently, the generated data keys were stored in the locker component of the store. Whenever a fintech firm user made a transaction call, a one-time dynamic credential in the form of a temporary token was generated synchronously consisting of the last 4 digits of the card to get access to the card details required at the payment gateway. After completing the transaction, the token timed out further preventing any identity theft.
DataSahi, our PDF parsing tool helped scan millions of PDF documents each day, extracting useful information that helped customers with payment reminders and bank offers. DataSahi aimed to make it convenient for the client to extract various types of data like text, data fields and tables, reducing the hindrances that financial and compliance-related companies face in extracting data from large volumes of PDFs. Integrated with the client’s application, DataSahi set up the extraction without requiring complex commands, simply adhering to the rules for each specific document type. DataSahi has three key components:
The page resolution module gathers the input for parsing,
The extraction module applies the filtration, and
Finally, the extracted data from the PDF is converted into JSON format by the transformation module.
This fintech client offers a flexible line of credit, one of their most popular offerings. The entire customer journey can be divided into two cycles - the drawdown cycle, which avails loans to users and the repayment cycle, where users pay EMIs. Facilitating these two cycles required reconciliation with the bank. A business ops team from 91social helped with the customers’ lending journey from the drawdown cycle to the repayment cycle and finally the reconciliation process. 91social responds to daily production issues in Jira, resolving customer complaints raised to the customer support team, creating SOPs to proactively prevent occurrences in the future, and finally updating the status of issues to the client’s product operations team.
91social also created a process workbench known as the heartbeat for customer journey mapping, which now forms a central pivot to all product feature designs driven directly by marketing with minimum technology team involvement. The workbench drives a best-in-class design management process besides improving visibility across the organization.
