At TIRWIN, I lead technical design and implementation for web platforms, cloud-hosted solutions, business integrations, and workflow automation. I develop platforms using Next.js, Amazon S3, and CloudFront, and design recruitment workflows that connect forms, scheduling, reminders, and analytics.

At BRILLIO, I built a social data analytics platform with NestJS and third-party integrations, adding search and analytics with ElasticSearch and OpenSearch.

At UNIVERSAL MUSIC GROUP, I developed applications and REST microservices for music content management and streaming, and architected secure login APIs across brand properties. I also integrated Shopify applications and optimized SQL queries, indexing, and caching.

At EBAY INC., I led cross-functional engineering efforts to deliver Passport, a passwordless corporate mobile authenticator for Android and iOS. Earlier, I designed enterprise web and mobile backend systems at COGNIZANT and developed banking and financial services applications at POLARIS.
