🚀 Architected a full-stack Tinder-style

🚀 Architected a full-stack Tinder-style networking platform exclusively for developers and corporate professionals, enabling swipe-based matchmaking, real-time chat, and skill-driven discovery built end-to-end with TypeScript across React frontend and Node.js/Express backend for type-safe contracts. Designed a normalized PostgreSQL schema with Drizzle ORM, leveraging type-inferred queries, migrations, and relational joins to power user feeds, connection requests, match history, and chat threads with sub-100ms query performance. Implemented secure authentication with access + refresh JWT rotation, HTTP-only cookies, and multi-provider OAuth (Google, GitHub) alongside email/password signup verified via AWS SES transactional emails — reducing fake-account signups significantly. Built a RESTful API with 15+ endpoints spanning auth, profile, feed, connection-request, match, and chat modules, hardened with role-based middleware, request validation (Zod), bcrypt hashing, and rate limiting to mitigate brute-force and abuse. Deployed the production stack on AWS EC2 behind Cloudflare for DNS, CDN caching, DDoS protection, and SSL termination, with a custom domain configured via GoDaddy and CI-friendly environment isolation across dev/staging/prod. Engineered the React client with a component-driven architecture, optimistic UI for swipes/matches, protected routes via refresh-token interceptors, and responsive Tailwind-based design delivering a polished mobile-first experience.
