About Me

Clean code. Great teams.
Real impact.

Hello! I'm Pranav Reddy Pajjuru, a Full Stack Java Developer with 4 years of experience building cloud-native, microservices-based enterprise applications in Healthcare and Insurance domains across the United States and India.

Currently at McKesson (Jan 2024–Present), I build pharmacist dashboards in React/Redux, Spring Boot microservices, and Kafka-driven prescription pipelines processing 10,000+ daily transactions with zero message loss. Previously at Progressive Insurance, I overhauled 100+ Spring Boot REST & SOAP services supporting $2M+ in annual digital policy revenue.

My stack is deep on the JVM side — Java 8/11/17/21, Spring ecosystem, Kafka — paired with solid React frontend skills and hands-on AWS (EKS, EC2, S3, RDS, DynamoDB) deployments using Docker, Kubernetes, and Terraform.

Engineering Philosophy

How I build reliable
and scalable systems.

⚙️
Scalable Architectures
Design microservices and event-driven systems capable of handling high throughput and production workloads.
📡
Event Driven Thinking
Use Kafka and asynchronous communication to build loosely coupled and resilient distributed systems.
⚡
Performance First
Apply caching (Redis), optimized queries, and efficient API design to reduce latency and system load.
🔍
Observability
Build systems with logging, monitoring, and metrics using Prometheus and Grafana for reliability.
