May 2024 - Present

Designed and developed backend APIs (Node.js, GraphQL) integrated with an enterprise CRM Hub, enabling real-time data synchronization across user and order workflows. Implemented caching layers and optimized GraphQL queries, reducing API response time by 30%+ and improving overall system responsiveness. Built a role-based access control (RBAC) and profile management system at the API layer supporting multiple user roles, improving system security and reducing unauthorized access issues. Architected and built an Admin Portal backend from scratch (Node.js, MongoDB) with 10+ modules and supporting APIs. Streamlined internal workflows through the new Admin Portal’s modular design, reducing manual internal processes by 40%+. Led migration of core services from React.js to Next.js (including SSR and API routes), improving page load speed by 25–35% and reducing initial render time across key user flows. Developed backend support for internationalization (i18n) across 5+ regions, enabling expansion to global markets. Set up and maintained CI/CD pipelines and Docker-based deployments, reducing release time and improving deployment reliability. Built 30+ reusable React components consumed across the frontend, cutting development effort for new features by 25%. Integrated an LLM-based (OpenAI API) auto-summarization feature into the Admin Portal, using it to generate quick summaries of customer records and reduce manual review time for internal teams.
