Hi, I build full-stack MERN platforms with native Android counterparts and can deliver every requirement listed. Stack: React.js (web + mobile-optimized variant) · Node.js/Express REST API · MongoDB/Mongoose · Android Studio (Retrofit + OkHttp). All three clients share one MongoDB instance via a single secured API layer. Auth & security: JWT access/refresh tokens, bcrypt hashing, email verification, password reset via Nodemailer, express-rate-limit, express-validator on all inputs. Multi-language support via react-i18next (web) and Android resource strings. Deliverables, point for point: 1. React web app + responsive mobile-web variant + Android Studio project 2. Express API — full CRUD, auth middleware, protected routes 3. MongoDB schemas + Mongoose models + seed scripts 4. Setup docs — env vars, dev & production deployment guide 5. Written walkthrough covering sign-up, login, password reset & email verification across all three clients Unit tests (Jest + Supertest) cover all auth routes and critical API endpoints. Code is clean, commented, and structured for scale. One question before we start: should the mobile-web variant be a PWA with offline support, or a standard responsive build? Clarifying this upfront keeps architecture aligned. Ready to begin immediately. Regards, Basant

@ApieTech

Hi - read the brief. The combo (React web + a separate mobile-web variant + native Android in Android Studio, all on one Mongo + Node API) is unusual but doable. Want to flag one architectural choice early before we both commit time. Two paths for the Android side: 1. Pure Android Studio in Kotlin/Java as you described - clean native experience, two separate codebases for mobile (web + Android) to maintain 2. PWA for the mobile-web + a light Kotlin shell that wraps it, OR Flutter for native Android - one codebase, faster shipping Happy with option 1 since that's what you asked for, just wanted to surface 2 in case it saves you maintenance later. What we will deliver - React web (responsive) + mobile-optimised web variant - Android Studio project sharing the same REST API - Express + JWT auth, email verify, password reset, rate-limit, input validation (Joi/Zod), i18n via i18next/Android string resources - Mongo schema + seed scripts - Unit tests on auth and critical CRUD - Setup docs, deploy guide, walkthrough video Quick question - Native Android and mobile-web - identical features, or anything Android-only (push, camera, biometric)? - APIE Technologies | MERN, Android, Kotlin
