Developed and spearheaded an in-house omnichannel platform (Golang) that empowered the Ops team to independently launch campaigns across SMS, Push Notification, Email, and Voice. Established a robust microservice architecture with REST APIs to support campaign management, message templating, and user segmentation for targeted communication. Implemented gradual rollout logic (e.g., 100% for email, 30% for SMS), enabling a safe and controlled transition across a 2M+ active user base. Developed a custom Google SSO authentication layer with internal-only email access, single-use token support, and safeguards against SSRF vulnerabilities, improving platform security. Collaborated with frontend, product, and QA teams to ensure end-to-end delivery of omnichannel campaign features.

Credit Scoring - Enhanced the credit scoring system by integrating third-party data providers such as AFP I, CLIK, and AAI, enabling more accurate credit assessments for users with thin or poor credit history. Engineered automated decision workflows using Kafka, reducing credit scoring time from 30 minutes to 5 minutes, resulting in faster loan approvals and improved user experience. Helped reduce Non-Performing Loans (NPL) by 35% through strategic improvements to the scoring model, contributing to financial stability and loss mitigation.
