Bhanu Pratap Das

Architected a distributed resource orchestration platform using Java (Spring Boot) across 3 microservices, enabling scalable multi-tenant workloads on Kubernetes. Built fault-tolerant async event processing with retries and idempotency, achieving <200ms latency using Redis Pub/Sub. Designed REST APIs (OpenAPI), enabling parallel development. Developed config generator for Docker/K8s, reducing provisioning effort by 30%. Implemented observability (Grafana, Prometheus). Led 3 engineers, reducing PR cycle.

Designed and built a high-performance authentication microservice for 3D Secure payment flows, achieving 92% success rates — owning the service from design through production at peak transaction scale. Architected and executed cloud migration of fraud detection and authentication services to AWS, improving system uptime, scalability, and resilience under high-load production conditions. Collaborated closely with partner teams to translate functional and non-functional requirements.

Designed and implemented REST APIs for a customer-facing scheduling platform; improved booking efficiency by 70% through backend architecture improvements. Optimised SQL queries and database design, reducing backend response times by 20% — demonstrating strong performance tuning and analytical problem-solving. Achieved >85% JUnit code coverage through rigorous test design; contributed to code reviews and engineering quality standards across the team.

Developed Java-based backend platform services powering Apple CRM applications processing millions of daily transactions — largest-scale production system in career; reduced response latency by 20% through architectural optimisation. Designed a fault-tolerant Java scheduler synchronising 3M+ records/month across distributed systems, ensuring data consistency and operational reliability at scale. Collaborated with distributed teams to deliver reliable, high-performance backend services.
