Software Engineer with 4+ years of experience designing and building scalable, production-grade backend systems using Java, Spring Boot, and Microservices architecture. I specialize in high-concurrency distributed systems, having architected platforms that handle 26K+ concurrent users. My work spans the full backend stack — RESTful API development, Redis caching, Kafka-based async processing, SQL optimization, React.js frontends, and AWS cloud deployments. 🔧 What I work with: • Backend: Java, Spring Boot, Spring MVC, Spring Security, Microservices, JPA/Hibernate • Frontend: React.js, HTML5, CSS3, JavaScript • Databases: MySQL, Redis, Cassandra • Messaging & Cloud: Kafka, AWS (EC2, S3), Docker • Architecture: System Design, HLD, LLD, Design Patterns, Distributed Systems 🚀 Key highlights: • Built an end-to-end high-scale exam platform supporting 26K+ concurrent users with real-time proctoring (webcam monitoring, screen tracking, violation detection) • Migrated legacy JSP monolith to React.js SPA — improving performance and maintainability • Integrated Delhivery, DTC, and Salesforce APIs for automated logistics and shipment tracking • Maintained 99%+ uptime during peak exam events through caching, Kafka pipelines, and schema optimization • Hands-on with HLD/LLD — sequence diagrams, ER diagrams, and scalable service design I enjoy solving complex engineering problems, owning production systems end-to-end, and contributing to teams that care about code quality and system reliability.
