Building products that solve real problems
I am Dhiraj Kumar, a software engineer and full-stack developer with hands-on experience building production-grade web applications. Currently pursuing B.Tech in Computer Science & Engineering at Gurukul Kangri University, my work spans React, Node.js, and cloud architecture.
I've shipped three production products — from a jewellery inventory management system with ₹8.5L monthly GMV to a wholesale B2B platform serving 50+ retailers. My work spans RBAC auth systems, WebSocket real-time engines, OCR pipelines, and AI/ML integrations.
When I'm not coding, I explore the intersection of artificial intelligence, automation, and agentic systems. I share my learnings through technical writing and open-source contributions. I've solved 400+ LeetCode problems and hold certifications from IIT Kharagpur, Microsoft, and Google Cloud.
