VIKAS MANDAL

I’m a Java Developer and Full Stack developer with 4.5+ years of experience building scalable backend systems using Java and Spring Boot. I design microservices, REST APIs, and distributed systems with a focus on performance, reliability, and clean architecture.

In my current role as a Technical Consultant at Perficient, I architected and deployed scalable Java 8 & Spring Boot microservices on AWS EC2, enabling event-driven processing that improved scalability and eliminated deployment downtime. I also led enterprise search work—integrating Coveo search across platforms with REST APIs, connectors, and web crawlers to improve real-time indexing and product discoverability.

I’ve delivered measurable wins like a 35% reduction in query response time through an Endeca to Bloomreach migration, overhauling distributed search architecture for long-term maintainability. I’ve also built and optimized high-throughput ingestion, including the Simcat crawler for Elasticsearch and Coveo, and hardened security by implementing Spring Security with SAML2 authentication.

Previously, as an Associate Technical Consultant, I architected reusable Spring Boot modules for data migration and connector development, upgraded legacy Spring applications, and migrated search infrastructure to Elasticsearch and OpenSearch. Across my projects and consulting work, I blend backend engineering with frontend delivery (React.js and Angular) and automation (Docker, Kubernetes, Jenkins) to ship production-grade features end-to-end.
