Full-stack Developer

Nov 2024 – Jul 2025 · 8 mos · Noida, Uttar Pradesh, India · On-site

At TrioTree Technologies Pvt Ltd, I developed and maintained enterprise-grade eHealth CRM systems with modular dashboards and reusable UI components. I led the implementation of critical modules including Patient Appointment Booking, Doctor-Facility Mapping, Camp Request Management, and Calendar-based Slot Booking. My role involved building interactive and responsive interfaces using React, Vue.js, and jQuery, seamlessly integrated with server-side APIs. I worked on integrating and testing RESTful APIs and SQL stored procedures for features like Bulk Requests, Return Blood, and Doctor Availability. I enhanced the user experience by optimizing dropdown caching, implementing conditional field rendering, and managing complex component states. Additionally, I collaborated closely with business analysts and stakeholders to refine Business Requirements Documents (BRD) and ensure all development was aligned with business objectives.
