Cover image for Ekdant Dental Clinic Smart Clinic
Ekdant Dental Clinic Smart Clinic Website with Live Queue Integration A fully custom clinic website built and integrated with VIXIT Clinic ERP turning a static dental clinic presence into a fully automated patient experience. The Problem: Patients had to call the clinic to book appointments. Receptionists wasted time on the phone. Patients had no idea how long they'd be waiting. What I Built: A professional clinic website with a "Book Now" button powered by VIXIT automation — patients fill a form, pick their reason for visit, and the system handles everything from there. How it works end to end: Patient clicks Book Now → fills form with details and reason for visit Receptionist and doctor get instant notification Patient receives a Token Number automatically When they arrive, the clinic's Live Queue TV screen (powered by VIXIT) shows real-time token updates Patients sit calmly in the waiting room — they know exactly when their turn is coming Result: Zero phone calls for bookings. Zero confusion in the waiting room. Fully automated from website click to doctor's chair. Tech behind it: VIXIT Clinic ERP · Live Queue System · Real-time token display · Automated notifications · Custom website integration · Node.js · PostgreSQL and many more stacked for a powerful and premium experience Live: Ekdant Dental Clinic , integrated with clinic.vixitai.com (http://clinic.vixitai.com)

Cover image for VIXIT Clinic ERP — Smart
VIXIT Clinic ERP — Smart Healthcare Management for Modern Hospitals and Clinics including Medical Billing shops A production-grade, multi-tenant clinic ERP I designed, built, and deployed solo — currently live with 50+ clinics and 2,400+ patients managed. What it does: Handles everything a clinic needs — patient registration, queue management, appointments, consultations, prescriptions, pharmacy POS, lab orders, billing with GST, and digital Rx delivery via WhatsApp and PDF. Tech Stack: Node.js · PostgreSQL · Redis · Express · PM2 (4-instance cluster) · Nginx · Hetzner VPS · JWT Auth · ioredis caching Security hardened: AES-256 encryption 5-attempt login lockout with 15-min cooldown Full audit logs on every auth event Fail2ban actively blocking 8,700+ malicious IPs 99.9% uptime SLA Why it's different: Most clinic software in India costs ₹5,000–₹15,000/month per clinic. VIXIT delivers the same — queue systems, digital prescriptions, pharmacy, billing at a fraction of the cost. Built lean, deployed fast, no bloat. Built by one person. No agency. No team of five. Just focused engineering with experienced years of 5 🔗 Live: clinic.vixitai.com (http://clinic.vixitai.com)

Cover image for NBA Mini-Documentary Cinematic Sports Storytelling &
NBA Mini-Documentary Cinematic Sports Storytelling & Video Editing This project focused on transforming a researched and scripted NBA story into a 10–14 minute cinematic YouTube mini-documentary designed to keep viewers emotionally invested from beginning to end. Rather than approaching the edit as a traditional basketball highlight reel, I treated it as a narrative film, using real game footage, interviews, press conferences, archival material, music, and sound design to support the progression of the story. The visual approach drew from modern sports-documentary storytelling, where pacing, footage selection, audio, and transitions work together to create tension, context, emotion, and payoff.

Cover image for From Chaos to Clarity A cinematic
From Chaos to Clarity A cinematic one-take product film exploring the moment when digital overload becomes effortless control. The film begins inside a dense, noisy workspace where notifications, tasks, messages, and overlapping interfaces gradually create a sense of information overload. Rather than matching that chaos with fast cuts, the camera remains deliberately slow and composed. Then everything stops. Silence creates the turning point as the product takes control. The clutter recedes, information reorganizes, and the experience transforms into a calm, focused workspace. Built around real product UI and continuous camera movement, the film uses sound, motion, lighting, and color to tell a simple story: complexity doesn't need more noise - it needs clarity. Created in CapCut Video Studio with Seedance 2.5 as a continuous one-take AI film.
