## About

```text
At Growth Catalysts, I developed a Healthcare AI platform using Node.js, microservices, PostgreSQL, Vue.js, and RESTful APIs, delivering sub-200ms response times. I also integrated OpenAI and Mistral AI APIs to automate healthcare workflows.

At Nexval InfoTech Pvt. Ltd, I designed HRMS applications and refactored monolithic applications into modular, service-oriented architecture, improving performance by up to 40%. I also developed real-time booking and scheduling modules using Node.js, WebSockets, MongoDB, and Vue.js.

At Kweb Technologies, I built a subscription-based LMS platform from scratch with Stripe payment integration, OAuth2/JWT authentication, and AWS S3 storage. Across my roles, I've delivered commercial projects in healthcare, HRMS, SaaS, e-commerce, and marketplace domains.
