As a developer, I’ve always had the itch to build — products, startups, ideas. Like many others, I’ve sat down countless times to turn a concept into code. But every single time, I ran into the same roadblocks: setting up authentication, designing a clean architecture, and building a codebase that could scale beyond an MVP.
Authentication: The First Wall
Authentication was always the first pain point. Whether it was OAuth, JWTs, session handling, or just basic user login flows — getting it right took too long. And even when it worked, the implementation often felt like a patchwork of code that I had to revisit and refactor later.
Architecture Matters
Then came the broader architectural challenge. I didn’t want to just hack something together that worked for now. I wanted a codebase that made sense — one that was modular, clean, and could scale as the project evolved. More importantly, I wanted something other developers could jump into and extend without needing to unravel a mess of spaghetti code.
After repeating this same process across multiple projects, I had a realization:
Why am I solving the same foundational problems over and over again?
That’s when the idea hit me — why not build a reusable solution?
Introducing: Full-Stack Clean Auth Template
The Authentication Template Project is the result of that realization.
It’s an open-source template built with Next.js, Express, Node.js, and TypeScript. But it’s more than just a login form — it’s a full-stack boilerplate designed with clean architecture principles, modularity, and scalability in mind.
Key Features:
Clean architecture separation (domain, application, infrastructure)
Fully modular and easy to extend
Scalable backend and frontend structure
Built with TypeScript end-to-end
Comprehensive documentation to get started quickly

Why This Matters
If you’ve ever tried to launch a product, you know how quickly authentication and architecture decisions can slow things down. This template is meant to remove those roadblocks. You can jump straight into building your core features, knowing the foundation is solid.
And I didn’t build this just for myself — I made it open-source because I know other developers are running into the same issues. Whether you’re building a SaaS, a side project, or a startup MVP, this template is designed to save you days of setup time and decision fatigue.
Community-Driven and Extensible
The project is built to grow with the community. You can contribute support for additional front-end frameworks like Angular, or even mobile apps like React Native, without disrupting the existing core.
I’m actively maintaining the project and looking for contributors who want to help shape the future of the template. Feedback, PRs, and suggestions are all welcome.
This is more than a boilerplate — it’s a foundation. If you’re tired of reinventing the wheel every time you start a new project, I built this for you.
Give it a try, and let me know what you think. If it saves you time or simplifies your next build, that’s mission accomplished.
