PROJECTS

RoyalInvites | Personalized Cinematic Wedding Invitations

2026

Next.js 16 · TypeScript · Tailwind CSS · Framer Motion · MongoDB Atlas · NextAuth.js · Cloudinary

  • Built a full-stack SaaS platform that replaces static PDF/image wedding invitations with personalized, cinematic web experiences, including an interactive wax-seal opening animation, background audio, and 4+ visual templates.
  • Engineered a stateless, encoded guest-link system that renders a personalized greeting and message per guest at runtime, avoiding a database record for every recipient while keeping the platform lightweight.
  • Developed a self-serve host dashboard for multi-ceremony wedding timelines (Haldi, Mehendi, Sangeet, etc.) with direct Google Maps venue navigation and one-click, pre-formatted WhatsApp invitation sharing.
  • Added client-side image compression before Cloudinary upload and automated cloud media cleanup on image replacement/deletion to prevent orphaned files and reduce storage overhead.

Impact: Live, production SaaS product used to invite real wedding guests; built and shipped end-to-end as an independent, AI-assisted full-stack build.

Senior Data Analyst Portfolio & Custom CMS

Client Project · 12/2025

Next.js · TypeScript · Tailwind CSS · shadcn/ui · MongoDB · NextAuth.js · TipTap · Cloudinary · Resend API

  • Delivered a professional portfolio and a bespoke "Digital Command Center" admin panel for a Senior Data Analyst client to publish case studies, blogs, and a downloadable resume without writing code.
  • Designed a hybrid-cloud architecture that kept the client's existing Hostinger domain/email while routing web traffic to Vercel, completely eliminating the need for a paid VPS.
  • Integrated a TipTap "MS Word-like" rich-text editor with image alignment and a draft-mode workflow, plus Cloudinary-powered image storage and optimization, for fully self-serve content publishing.
  • Built a high-speed, triple-action contact form (Resend API) that simultaneously logs leads to MongoDB, alerts the admin, and auto-confirms the visitor, alongside a message inbox with read/unread tracking.
  • Secured the platform with password + hashed, auto-expiring OTP 2-factor authentication, ensuring login codes stay useless even in the event of a database leak.

Impact: $0 recurring hosting cost vs. a paid VPS, 100% no-code content management for the client, and a one-click newsletter broadcast on every new publish.
