About

I build backend systems where reliability and scale are non-negotiable — lending platforms processing thousands of deals, payment infrastructure serving millions of users, and workflow platforms that automate complex fintech operations at scale. At Yubi (India's largest enterprise debt platform), I architected Kafka + Temporal based lending workflows supporting 500+ lender integrations and 10,000+ daily transactions, cutting deal closure time by 60% and eliminating 70% of manual effort through end-to-end workflow automation. At Grab, I led the PayLater product launch in a new Southeast Asian market, onboarding 10,000+ users in the first month. Core stack: Java, Spring Boot, Kafka, Temporal, PostgreSQL, Redis, MongoDB, Elasticsearch, Docker, Kubernetes, AWS Open to senior backend and staff engineering roles at product-focused companies building at scale — vijay.kumar.eee15@iitbhu.ac.in

  • Architected a greenfield Order Management Service using Java, Spring Boot, and Temporal for distributed saga orchestration. Chose orchestration over event choreography to enforce strict state-transition guarantees across 5+ downstream services. The platform now processes 10,000+ weekly transactions and reduced deal closure time by 60% (~25 days to ~10 days), significantly accelerating Yubi’s fund deployment cycle.
  • Designed and built a DSL-based Workflow Service that made lender workflows fully configuration-driven, including task sequencing, CTA definitions, actor assignment, and state-transition rules. Eliminated code deployments for new lender onboarding, reducing onboarding time from days to hours.
  • Led the integration of a third-party chat vendor into an in-app Communication Service, replacing fragmented email-based coordination with real-time contextual messaging between lenders and borrowers. Reduced deal turnaround time by 75% while improving communication transparency across the platform.
