About Sumit Yadav
As a Backend Engineer, I design, optimize, and scale payment and billing systems using Java, Spring Boot, Kafka, MongoDB, and AWS. At Deutsche Telekom Digital Labs, I engineered a Billing DPS from scratch, migrating 800K+ user records with GDPR compliance and accelerated delivery using AI tools like Copilot and Windsurf. Previously at Pristyn Care, I spearheaded digital healthcare transformation, optimizing APIs for 20K+ users daily. Recognized as The Alchemist, I thrive on delivering mission-critical systems with zero compromise on scalability or compliance.
