Hi, I am Sunit Mohan
AI first Software Engineer enhancing high-traffic platforms with userbase in millions and building scalable production experiences.
01. About Me
Full-stack software engineer who thinks in systems, not tickets - architecting and shipping complete products (access control, authentication, deployment) rather than isolated features. Experience building scalable React/Next.js frontends and Node.js/Medusa.js backends for platforms serving 8M+ monthly users, plus hands-on agentic AI development (Claude Code, GitHub Copilot, OpenAI Codex, Google Antigravity) and multi-model LLM integration (Anthropic, OpenAI, Google).

- ▹ Architecting and building a new internal marketplace product end-to-end (React/TypeScript admin UI + Medusa.js/Node.js backend) spanning 5-10 admin and catalog modules, currently being integrated with ICICI iRewards to power an estimated INR 30 Cr in annual revenue.
- ▹ Designed the platform's access-control system from the ground up: a 3-tier RBAC model (super admin, catalog admin, catalog viewer) using custom React hooks and permission-gated components.
- ▹ Built enterprise-grade authentication: Azure AD SSO (OAuth 2.0/OIDC via MSAL) with Conditional Access/MFA, plus two-factor authentication (2FA) for privileged admin roles.
- ▹ Owned backend deployment on AWS EC2 and drove platform stability by diagnosing and resolving critical defects ahead of UAT.

- ▹ Led the frontend side of migrating a 5+ year legacy AngularJS codebase to Next.js (React), rebuilding 15+ modules and refactoring 20+ components into a reusable TypeScript library, improving development velocity by ~25%.
- ▹ Improved platform reliability by resolving 50+ production issues, and independently designed and shipped a WhatsApp Business automation system (Node.js, WABA, Sinch, CRM) for automated booking confirmations and promotional campaigns.
