• As part of the FinTech group at Uber, I independently built products and utilities to streamline workflows, reduce manual effort, and drive efficiency across various financial and operational domains.
• Key Projects:
• Tech Stack: Golang, React JS, Oracle, MySQL.
• USurv: A one-stop solution for Source-to-Pay requirements.
• UCertify: An app for Audit & User Access Review (UAR) processes.
• Tech Stack: Java, Bootstrap, Angular, MySQL, Oracle.
• Sockbox (Vehicle Management System): Designed and developed an end-to-end system for Uber City Ops in Singapore to manage one of the largest vehicle rental businesses. Streamlined the vehicle lifecycle and integrated data into downstream systems.
• Nitro (XSLT Payment Automation Engine): Conceptualized and built a tool to automate the creation of payment templates for vendor payments, enabling Product Managers to roll out entities faster without engineering support. This reduced turnaround time for city launches and streamlined payment workflows.
• FAST (Access Provisioning Solution): Developed an enterprise-wide system to automate access provisioning across numerous internal and third-party applications, eliminating manual processes and creating a one-stop solution.
• Additional Contributions:
• Worked on Oracle Financials Development & Support, including system integrations, reporting, and ETL pipelines across modules like Oracle Applications, Workday, Coupa, and Expensify.
• Engineered integrations between internal and external systems to support finance operations and enhance system interoperability.

• As a Full Stack Developer at Uber, I focused on developing scalable products using open-source technologies and enhancing integrations between key enterprise systems such as Oracle, Coupa, Expensify, Workday, and others. My work streamlined operations, automated processes, and reduced manual intervention for product managers and finance teams.
• Key Contributions:
• Workday to Oracle Integrations: Engineered solutions to synchronize employee and bank account data from Workday to Oracle.
• Designed generic lookups to empower product managers to manage new column changes independently without engineering involvement.
• Oracle to Coupa Integrations: Integrated users, cost/accounting segments, exchange rates, and addresses from Oracle to Coupa.
• Overcame performance challenges of slow Coupa APIs by leveraging Java Multi-Threading for parallel API calls, significantly improving efficiency.
• Made configurations flexible to allow product managers to apply custom rules by cost center or entity during rollouts.
• Payment Schedules Automation: Developed a utility to automate vendor payments and employee expense reimbursements for various cities (weekly/bi-weekly/monthly).
• Reduced significant manual effort for the payments team.
• Oracle/Certa Integrations: Built integrations between Oracle and Vetted, a cloud-based vendor onboarding platform, using Java and PL/SQL.
• Oracle Expensify Integrations: Automated the integration of expense policies from Oracle to Expensify using OA Framework, Java, and PL/SQL.
• Oracle Financials Modules: Delivered multiple automation solutions and XML Publisher reports for modules like Payables, Fixed Assets, General Ledger, Sub Ledger, Cash Management, and Receivables.
