Full-Stack Next.js Developer (Mid-Level) in Grow My Ads

About Us

Grow My Ads is a US-registered PPC agency helping businesses scale their digital advertising efforts. We're building our own internal billing and agency management platform to streamline how we manage clients, handle payments, and run our operations.

The Role

We're looking for a skilled developer to join us in building a custom billing system — handling subscriptions, invoicing, payment processing, refunds, discounts, analytics, and reporting. The billing system will eventually integrate with our separate client management platform, which covers performance tracking, CRM, and sales management.

This position starts as a project-based contractor role for several months, with a strong potential to transition into a permanent position based on performance and mutual fit.

Our stack is built on Next.js and PostgreSQL. You'll be working with:

• Modern React 
• Next.js with App Router
• Server and Client Components
• State management: Redux, Zustand, or Context API
• Server actions and API routes
• PostgreSQL database
• Stripe API integration
• Third-party API integrations (Google Ads, Meta Ads, etc.)
• RESTful APIs and async workflows
• AI coding tools (Claude Code, ChatGPT Codex, Cursor, Windsurf)

What We're Looking For

• Strong experience with Next.js and React (App Router, server/client components)
• Proficiency with state management solutions (Redux, Zustand, Context API)
• Solid understanding of server actions and API routes
• Experience with REST APIs and asynchronous workflows
• Working knowledge of SQL/NoSQL databases (PostgreSQL preferred)
• Proven track record integrating third-party APIs, payment gateways (Stripe preferred), and external services
• Familiarity with AI-assisted development tools (Claude Code, ChatGPT Codex, Cursor, Windsurf) is a plus
• Proficient with Git and branching strategies
• English level: Intermediate or higher

What We Offer

• Compensation: $1,500 - $3,500/month based on your experience, interview performance, and English proficiency

• Growth opportunity: Start with project-based work with a clear path to a permanent role
