About Subham Roy

I\'m a Full Stack Engineer with over 3 years of experience building scalable, performance-driven web applications and internal platforms at enterprise scale. I specialize in React, TypeScript, and Node.js, and have built everything from Kafka UI tools and data visualization systems to analytics dashboards and startup platforms.At TCS, I led the development of complex UI tools such as a Data Lineage Visualizer using D3.js and “Replay” — a Kafka message UI that streamlined internal dev workflows. I’ve also rebuilt monolithic architectures into modular frontends, developed automation-driven UX improvements, and contributed to tools replacing paid ETL solutions like Talend.At Cognizant, I worked on a full-stack project management & ETL dashboard using MERN stack. I implemented secure RBAC systems, integrated KPI metrics from Jira, and launched reusable modules that enhanced engineering visibility and productivity.Outside work, I build and ship side projects like StudyNest (a PG/hostel finder for students) and StartUpHub (a 50-word startup news digest with audio), showcasing my passion for clean UI, fast feedback loops, and user-first design.
