@corpmember29

((DENASIS)) Hello, I have reviewed your complete requirements for the React Native login application, Node.js REST API, and PostgreSQL authentication setup. I have 10+ years of experience in software development, working with React Native, TypeScript, Node.js, REST APIs, PostgreSQL, JWT authentication, database architecture, and scalable application development. I have experience building secure authentication systems, multilingual mobile applications, API integrations, and production-ready solutions. For this project, I will develop: • React Native (TypeScript) login screen matching your design • TR/EN localization using i18next • Secure JWT access and refresh token authentication • Node.js REST API with validation, error handling, and clean architecture • PostgreSQL schema, migrations, and seed data • Privacy Policy modal with version-based acceptance tracking • Swagger/Postman API documentation • Complete source code and setup documentation I will follow an agile methodology with regular progress updates and ensure the application is tested properly before delivery. I WILL PROVIDE 2 YEAR FREE ONGOING SUPPORT AND COMPLETE SOURCE CODE. WE WILL WORK WITH AGILE METHODOLOGY AND PROVIDE ASSISTANCE FROM ZERO TO PUBLISHING ON STORES. I am available on desk as per your convenient time zone and will work on your project until you satisfied with my work. Thanks Christina

Hi, I checked your "React Native Login Screen, Node.js REST API and PostgreSQL Database Setup" project and it looks like the focus is on delivering a clean, responsive website that works well across all devices. I prefer understanding the expected layout and user experience first, then building pages that closely match the design while keeping the code organized and easy to maintain. Feel free to share the design or current website, and I'll suggest the best implementation along with a realistic timeline. Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

DENASIS Hi there, I have carefully read your complete project description and can develop the entire solution, including the bilingual React Native login module, secure Node.js REST API, PostgreSQL database, JWT authentication with refresh tokens, and a scalable architecture. The login screen will closely match your provided design and include all requested features such as form validation, loading/error states, password visibility toggle, forgot password flow, localized TR/EN support using i18next, and the Terms & Privacy Policy modal with acceptance tracking. On the backend, I'll implement clean architecture, secure authentication using JWT and Argon2/bcrypt, input validation, refresh tokens, password reset functionality, and comprehensive API documentation. I'll also provide the PostgreSQL SQL scripts, ORM migrations, seed data with a demo user, installation guide, translation files, and a well-structured Git repository. For a project of this scope, my estimated delivery time is 10–14 days. The fixed price can be finalized after reviewing the UI design and database schema to ensure an accurate quotation. Could you please share the attached UI design and PostgreSQL schema, and let me know whether you prefer Express, Fastify, or NestJS along with your preferred ORM (Prisma, TypeORM, or Sequelize)? Kindly send me message to discuss more in detail. Thanks.

Hi, I've built login systems with this exact stack multiple times. You mentioned bilingual support—I'll make sure the authentication flows work smoothly across both languages from day one. Message me to discuss the timeline and get started. Regards, Nurul Hasan

Hi, DENASIS. I will deliver the bilingual (TR/EN) React Native login screen with i18next, a Node.js REST API handling JWT/refresh tokens and Argon2 hashing, and the full PostgreSQL schema (Customers, Users, Roles, Policy Versions, Refresh Tokens, Password Reset Tokens) with migrations, seeds, and Swagger docs. On a similar auth setup, structuring refresh token rotation early prevented token replay issues in production. Questions: 1) Do you have a preference between Express, Fastify, or NestJS for the backend? 2) Will you provide the Figma file or is the attached PNG the final reference? Share the design file and I will match the UI pixel for pixel this week. Looking forward to talking through the details. Kamran

@gotucat

Hi, DENASIS I reviewed your login page requirements: a bilingual (TR/EN) React Native login UI with validation, secure JWT flow, and a scrollable Terms & Privacy Policy modal. You also need a Node.js REST API with refresh tokens and a PostgreSQL setup matching your schema, plus migrations, seeds, and API documentation. I’ll build the mobile login screen to match the provided design, using localization (i18next or equivalent), loading/error states, responsive layout, and form validation. On the backend, I’ll implement Express/Fastify/NestJS routes for login/logout/forgot/current user, hash passwords securely with Argon2 or bcrypt, add input validation, and wire JWT + refresh token handling to PostgreSQL. I focus on clean architecture, reliable error handling, and maintainable code structure for easy handoff. Let’s discuss here now.

@sharmarahulraman

DENASIS Hi, We have carefully reviewed your requirements and can develop the complete React Native login module with a secure Node.js REST API, PostgreSQL database, JWT authentication, bilingual (TR/EN) support, Privacy Policy modal, and clean, scalable architecture exactly as outlined. We'd be happy to discuss the details and get started right away.

@gutibs

DENASIS Hi! This is something we can handle without issues. One thing that would help me scope this properly: is this the foundation of a bigger app you're already building, or is the login/auth layer itself the full deliverable for now? That changes how we'd structure the architecture. For the stack, we'd go with React Native + i18next for localization, Express or Fastify on the backend with JWT + refresh tokens and Argon2 for hashing, and PostgreSQL with migration files and seed script as described. Swagger for the API docs. Clean, scalable folder structure from the start. Delivery would be around 7–10 days. Fixed price in the $200–230 range depending on your answer above. Looking forward to the details to lock in the scope. Gustavo & the DoTheCode team

Hey, DENASIS I’ve carefully reviewed your project, and I understand you need a secure, scalable authentication module with a bilingual React Native login screen backed by a robust Node.js and PostgreSQL architecture. I can help deliver a clean implementation that closely matches your design while ensuring security, maintainability, and a smooth user experience across Android and iOS. I will develop the React Native login flow with TR/EN localization, build the JWT authentication API with refresh tokens and password recovery, create the PostgreSQL schema with migrations and seed data, and provide complete API documentation and installation guidance. The solution will be thoroughly tested and structured for future expansion. I have hands-on experience with similar React Native and Node.js backend projects and would be happy to share relevant examples during our discussion. One quick question: Would you prefer the backend to be built with Express, Fastify, or NestJS, or should I recommend the best fit for long-term scalability?
