Arghyadeep Majumder
Senior Engineer & Solution Architect
I care about what I build —and I try to build it well. I have 7+ years of experience designing and shipping products end to end, in production. From microservices to React & React Native frontends — for millions of users across global enterprises and clients. Every layer, every cycle. Currently building Empuls, Xoxoday's employee engagement platform — across surveys, rewards, wellness, and mobile — using AI tools as force multipliers to ship faster without compromising quality.

🤖 AI Adoption Story
I ranked #1 on my org's AI usage leaderboard. This is how it happened.
When AI coding tools rolled out across the org, most engineers tried them. I committed to making AI a daily collaborator — not a shortcut, but a thinking partner across architecture, code reviews, debugging, and migrations. The discipline of prompt crafting, context window management, and knowing when not to trust the model started compounding — I was shipping more, faster, without cutting corners on quality. Accepted diffs climbed because the suggestions were actually correct, and I knew enough to validate them. By Q1 2026, the numbers were in: I had generated nearly 2× the agent lines of code of the second-ranked engineer.
| ✅ Accepted Diffs | 12,550 |
| ⚡ Tab Completions | 5,984 |
| 🧠 Agent Lines of Code | 641,650 |
The accepted diffs metric matters most — it reflects code that was good enough to actually ship. That number only grows when you understand your codebase deeply enough to guide the model, not just prompt it blindly.
Work Experience
