Rohit Kori — Full Stack Engineer

Senior Full-Stack Engineer | Java 11–21 · Spring Boot · React · TypeScript | Open to International Relocation | Visa sponsorship required I have 9+ years of experience building cloud-native distributed systems across telecom, fintech, and health-tech. My expertise spans Java and Spring Boot backend development, modern React and TypeScript frontends, microservices, event-driven architectures, and cloud-native platforms on AWS. Currently at BICS, I design and engineer carrier-grade telecom platforms that process 300+ SMS/second (~26M SMS/day) for global enterprise customers. I enjoy solving complex scalability challenges, modernizing legacy systems, and taking products from architecture and design through production deployment. Core technologies: Java 11–21, Spring Boot, Spring Security, Microservices, REST APIs, TypeScript, React, Next.js, JPA/Hibernate, Kafka, Redis, Elasticsearch, ActiveMQ, Oracle, MongoDB, PostgreSQL, Docker, Kubernetes, AWS (EC2, S3, Lambda, EKS, CloudWatch), CI/CD, Apache NiFi, Grafana. Highlights: - Scaled an SMS API platform from ~500 TPS to 1,000+ TPS while maintaining 99.9%+ availability. - Led the migration of a legacy JSF monolith to React (TypeScript) and Spring Boot microservices. - Designed and delivered telecom microservices supporting carrier-level voice and SMS controls. - Reduced regulatory report generation time by 75% at Arcesium for a high-volume compliance platform serving DE Shaw's algorithmic trading operations. - Built large-scale data integration pipelines using Apache NiFi and BigQuery at Apollo 24|7. - Led a team of 4 engineers to deliver a real-time tracking platform from concept to first paying customer. I am particularly interested in product-driven engineering teams where ownership, technical excellence, and customer impact matter. I enjoy collaborating across product, engineering, and operations teams to deliver scalable solutions that solve real business problems. Open to Senior Full-Stack Engineer and Senior Backend Engineer opportunities worldwide. Visa sponsorship required.
