Full-Stack Developer Needed for Online Tools Platform (PHP to Node.js/React Migration, AI Integration, Billing System)
Budget: $5 – $10 USD
### **Job Description:**
I’m building a **freemium online tools website** (unit converters, file tools, networking utilities, and future AI-powered features). I need an experienced full-stack developer to:
1. **Repurpose existing PHP scripts** into a modern Node.js/React platform.
2. **Implement user accounts, usage tracking, and billing** (Stripe/PayPal).
3. **Add security features** (rate limiting, authentication, API key management).
4. **Integrate AI tools** (connect to LLMs like OpenAI for premium features).
**Key Requirements:**
- **Back-End:** Strong Node.js (Express/NestJS) to rebuild PHP logic and handle licensing/billing.
- **Front-End:** React.js/Vue.js for a responsive dashboard.
- **Database:** PostgreSQL/MongoDB for user data and tool usage tracking.
- **APIs:** Experience with OpenAI API, payment gateways (Stripe), and JWT/auth.
- **DevOps:** Familiarity with deploying to AWS/Vercel.
**Nice-to-Have:**
- Experience migrating PHP to Node.js.
- Knowledge of serverless functions (AWS Lambda/Vercel Edge).
- Basic UI/UX skills (TailwindCSS/MUI).
### **Project Scope:**
- **Phase 1:** Migrate PHP tools to Node.js + build user/auth system.
- **Phase 2:** Implement billing/subscriptions (free vs. paid tiers).
- **Phase 3:** Add AI tools (e.g., text summarization, image generation).
### **Budget:**
- **Hourly rate:** $15–$35/hour (negotiable based on skill level).
- **Long-term work** possible for the right developer.
### **Preferred Qualifications:**
- Fluent English (clear communication is critical).
- Portfolio of similar projects (SaaS, toolkits, or AI integrations).
- Availability for weekly syncs (timezone flexible).
### **How to Apply:**
1. **Reply with:**
- Your experience with Node.js, React, and PHP migrations.
- Examples of past projects involving billing/AI APIs.
- Your proposed hourly rate and availability.
2. **Bonus:** Share a brief (1–2 sentence) plan for migrating PHP scripts to Node.js.

### **Why This Post Works:**
1. **Clear Scope:** Breaks down the project into phases to attract serious candidates.
2. **Targets Skills Needed:** Explicitly mentions PHP→Node.js migration and AI.
3. **Filters for Communication:** Emphasizes English fluency.
4. **Budget Transparency:** Avoids unrealistic lowball bids.
**Next Steps:**
- Post this on Freelancer.com/Upwork.
- Look for developers with **Node.js + React + Payment API** experience in their portfolios.
- Interview 3–5 candidates with a **small paid test task** (e.g., migrate one PHP tool to Node.js).
