SaaS Application Development

## Full-Stack SaaS Developer Needed for Adhify We are building **Adhify**, a SaaS platform that helps users deploy, manage, and operate web applications and related services from one dashboard. The platform already has an existing technical direction, and we are looking for an experienced full-stack developer who can help us improve the architecture, implement features, solve technical challenges, and prepare the product for production use. ### Current Technology Stack * Next.js * React * TypeScript * tRPC * Prisma * PostgreSQL * Supabase Authentication * Tailwind CSS * shadcn/ui * Docker * GitHub Apps and GitHub APIs * Coolify * Cloudflare and VPS infrastructure ### What You Will Work On Depending on your experience, the work may include: * Building and improving the SaaS dashboard * Implementing user authentication and authorization * Developing role-based access control * Improving multi-tenant architecture * Integrating GitHub repositories and GitHub Apps * Building deployment and service-management workflows * Connecting the application with Coolify and cloud infrastructure * Improving database design and backend APIs * Implementing subscription and usage-management features * Fixing bugs and improving existing code * Improving application security, reliability, and performance * Setting up deployment, monitoring, logging, and CI/CD workflows ### Who We Are Looking For You should have strong experience with: * Building production SaaS applications * Next.js, React, and TypeScript * Node.js backend development * PostgreSQL and relational database design * Authentication, authorization, and application security * Docker and cloud deployment * API integrations * Git and GitHub workflows Experience with developer platforms, hosting platforms, PaaS products, DevOps automation, Coolify, Kubernetes, AWS, or similar infrastructure tools will be a strong advantage. ### Project Status This is not only an idea-stage project. Some parts of the platform and infrastructure already exist. The selected developer will first review the current application, understand the architecture, identify technical risks, and recommend the best next development steps. We prefer someone who can take ownership of features, communicate clearly, and contribute to both implementation and technical decision-making. ### How to Apply Please do not send a generic proposal. Start your proposal with the words: **“I reviewed the Adhify requirements.”** Then answer the following questions: 1. What similar SaaS, developer platform, hosting platform, or DevOps-related product have you worked on? 2. How would you approach reviewing an existing Next.js, Prisma, PostgreSQL, and Docker codebase? 3. What are the main technical risks you expect in a platform that deploys and manages user applications? 4. How would you design secure communication between Adhify, GitHub, and Coolify? 5. What would you review first before adding new features? 6. Which parts of this project would you be most comfortable owning? 7. Please share one relevant project and explain your exact contribution. 8. What is your availability over the next three months? Also include: * Your hourly rate * Your weekly availability * Your time zone * Your preferred communication method * Links to relevant work, GitHub repositories, or technical case studies ### Important We are not selecting only based on the lowest hourly rate. We will prioritize developers who: * Understand the product and technical challenges * Explain their development approach clearly * Identify risks before starting implementation * Have relevant SaaS or infrastructure experience * Can communicate consistently * Can work independently and take ownership This may become a long-term collaboration for the right developer.
