About Pankaj Kalwar

I architect and lead high-throughput, event-driven backend systems that power scalable, secure, and mission-critical enterprise platforms.With 13+ years of experience in Java backend engineering and distributed system design, I specialize in building cloud-native, high-performance architectures using event-driven and microservices patterns. My focus has been on designing systems that scale predictably, remain operational under load, and align closely with business outcomes.I have led the architecture and delivery of Kafka-based, event-driven platforms enabling real-time communication across microservices, reducing system latency by 20–30% and improving horizontal scalability by 40%. These systems support high-volume workloads, including 250K+ transactions per hour, deployed on Azure Kubernetes Service (AKS).My architectural experience includes applying CQRS, and Event Sourcing to model complex domains and decouple services for long-term maintainability. I’ve also driven database performance optimizations (MySQL, SQL Server, Oracle) using indexing, caching, and data-model redesign, improving query performance by 25–30%.Beyond system design, I’ve owned end-to-end delivery and operational excellence — implementing CI/CD pipelines that reduced deployment time by 40%, embedding security best practices (authentication, authorization, encryption), and introducing observability and resilience patterns to minimize production risk.I regularly operate in a technical leadership role, mentoring 10–15 engineers, guiding design reviews, enforcing architectural standards, and collaborating closely with product, QA, DevOps, and business stakeholders to ensure technical decisions support long-term platform goals.My domain experience spans payment systems, document management platforms, and trade settlement systems, where correctness, reliability, and performance are critical.
