Full-Stack Web Application Deployment (MERN / React & Node.js)

Job ID: 40543897

Budget: ₹750 – ₹1,250 INR

Project Overview
We are seeking an experienced full-stack engineering team to develop and deploy a high-performance, responsive global web application and utility platform. The entire frontend must be built from scratch using clean, semantic React.js and Tailwind CSS, supported by a robust, secure Node.js and Express.js backend architecture.

This project enforces a strict Zero-Plugin / Zero-Template Policy. All performance optimization, state management, and asset delivery must be engineered natively within the codebase to guarantee uncompromised speed and stability.

Core Scope of Work & Functional Requirements
1. Frontend UI Execution (React.js & Tailwind CSS):

o Development of an 8-page fully responsive architecture using fluid typography and strict grid alignments.

o Integration of dynamic client-facing components, including interactive resource-scaling sliders and multi-input cost estimation forms.

o Implementation of native dark-mode styling utilizing specific, predefined design tokens and hex codes.

2. Backend Architecture & APIs (Node.js & Express.js):

o Development of an automated Geolocation IP filtering mechanism to handle regional user categorization.

o Integration of dynamic calculation engines to process multi-input form variables and output real-time structural cost matrices.

o Deployment of an isolated lead qualification layer that captures and routes communication data via external webhooks without bottlenecking public core application routes.

3. Payment & Deployment Gateways:

o Full integration of dual-currency payment gateway APIs (Stripe and domestic localized checkout hooks) to handle single-pass transaction processing and secure checkout callbacks.
o Secure deployment preparation on cloud container pools with streamlined version control.

Strict Performance Benchmarks
• The production application must achieve a native Mobile Core Web Vitals Largest Contentful Paint (LCP) 1.2 seconds.
• Target Mobile PageSpeed score must consistently benchmark at 95+ across Chrome, Safari, Firefox, and Edge browser engines without relying on third-party optimization libraries or plugins.

Collaboration & Compliance Onboarding Workflow
To protect proprietary data, structural logic, and system infrastructure parameters, our development roadmap utilizes a strict compliance gate:

• Step 1: Scope & Estimate Confirmation: Review these functional guidelines and confirm your fixed budget alignment.

• Step 2: Formal Mutual NDA Generation: Provide the full legal names of your lead developer and participating team engineers. A formal Mutual NDA will be generated and dispatched via email.

• Step 3: Technical Handoff: Upon receipt of the executed agreement, Milestone 1 will be funded, and your team's GitHub handles will be whitelisted for access to our private organization monorepo containing detailed wireframes, architecture blueprints, and API documentation.
