Pankajkumar Musale

Java Full Stack Engineer with 3.6+ years of experience developing low-latency microservices with Spring Boot, Kafka, and Redis alongside Angular frontends. Proven track record in cutting read-path latencies by over 60%, hardening application security (OWASP/RBAC), and automating CI/CD pipelines.

Software Engineer – Java Full Stack at 3i-Infotech (2023-03 – Present)

• Architected a distributed pre-computation caching layer using Redis to eliminate redundant on-the-fly computational bottlenecks across high-traffic read paths.
• Reduced downstream API latency by 65% by serving pre-aggregated payloads directly from memory rather than executing repetitive database queries.
• Integrated AWS S3 for scalable, off-database binary and structured file storage, optimizing primary database I/O performance.
• Designed and deployed an asynchronous data synchronization engine using Apache Kafka to stream state changes across distributed consumers in real time.
• Built resilient producer-consumer workflows with automated retry mechanisms, dead-letter topics, and structured logging to maintain high message throughput and zero data loss.
• Authored clean, decoupled RESTful APIs using Spring Boot, handling serialization, multi-tier error handling, and payload validation.
• Developed modular, responsive Single Page Applications (SPAs) in Angular/TypeScript, managing complex asynchronous state flows using RxJS Observables.
• Enforced fine-grained authorization via Spring Security, implementing Role-Based Access Control (RBAC) and token validations across all endpoint tiers.
• Resolved critical security vulnerabilities identified during VA/VAPT audits, hardening services against OWASP Top 10 risks, data leaks, and unauthorized payload access.
• Maintained high code health and test coverage using JUnit, SonarQube, and automated Git/Maven CI/CD pipelines.
