08.2019 - 09.2021
- Built Django 3.2 and Django REST Framework payment services supporting UPI, card, and net-banking flows through PayU and bank gateway APIs for about 150K orders per day, including idempotent webhook handling and Celery/RabbitMQ retry logic.
- Automated daily settlement and refund reconciliation with Pandas jobs that matched gateway reports against MySQL order records, reducing manual clearing of unmatched transactions from about 4 hours to under 40 minutes.
- Created PyTest suites and Postman collections integrated with Jenkins pipelines, maintaining payment modules above 85% coverage and reducing UAT defects by roughly one-third across quarterly releases.
- Used Python-based data analysis and anomaly detection to support payment-risk investigations and improve visibility into unusual refund and chargeback activity.
