I’m a backend-focused Computer Engineering student who builds production-ready server-side systems and scalable REST APIs. I’m driven by SaaS product development, and I enjoy designing reliable, high-performance backend services that hold up under real product constraints.

In my production experience at Softix Info Pvt. Ltd., I shipped customer-facing features and collaborated closely with backend engineers on REST API contracts. I integrated RESTful APIs, handled async data-fetching patterns, managed client-side state for a SaaS dashboard, and improved Core Web Vitals by optimizing rendering and adding lazy-loading—while contributing through agile sprints, code reviews, and cross-functional standups.

I also build end-to-end backend projects: a scalable E-Commerce REST API using Node.js, NestJS, TypeScript, MongoDB, and JWT with DTO validation, guard/interceptor-based architecture, indexing, aggregation pipelines, and role-based access control. For AI-backed work, I developed a Medical Chatbot inference backend with FastAPI, a fine-tuned BioBERT model, and explored gRPC for low-latency streaming, alongside careful biomedical NLP preprocessing. And in full-stack backend workflows, I created a Smart College Event Management system with REST APIs, real-time updates (Socket.io), and transactional email delivery (SendGrid).
