India

Message

At Spark Eighteen, I built the MVP of a multi-tenant Third-Party Risk Management platform within one month, onboarding 5 enterprise clients and supporting 100+ active users. I designed the database schema and developed 50+ REST APIs for authentication, vendor onboarding, approvals, third-party checks, and tenant-specific access control.

I architected nearly 85% of the backend, including RBAC, tenant isolation, and 15+ BullMQ queues. JSON processing pipelines handled 10,000+ vendor records, and I was promoted within 7 months for technical ownership and delivery.

At IndiaSME Forum, I served as the sole Full-Stack Engineer for MySmallBusiness, CIPRPF, State of the MSME, and LMS. I developed 30+ React screens and 60+ REST APIs, improved frontend load time, and deployed applications on AWS; earlier, at UtilitiesSave, I migrated the company website from WordPress to React and redesigned 10+ pages.
