Over the past few weeks, I wanted to challenge myself to build something more realistic than a typical demo project.
Instead of another small CRUD app, I decided to build an HRMS-style dashboard using Next.js 15 and TypeScript.
The idea was simple: design a system that feels like a real internal company tool — something that could eventually evolve into a SaaS.
What I Built
The dashboard currently includes:
- Employee management
- Attendance tracking
- Leave management
- Payroll structure
- Recruitment pipeline
- Organization chart
- A basic AI-powered assistant
This version is mostly frontend-focused, but I structured it with future backend and multi-tenant SaaS expansion in mind.
Tech Stack
- Next.js 15 (App Router)
- TypeScript
- Modular component structure
- API routes for AI assistant integration
What Was Challenging
One of the harder parts wasn’t building features — it was structuring the project in a way that wouldn’t become messy later.
Designing a reusable dashboard layout (sidebar + header + nested routes) while keeping components clean and modular required some iteration.
I also tried to think ahead about how authentication, company-level data isolation, and subscription billing could plug in later.
What I Learned
Building something “system-sized” changes how you think.
You stop thinking in pages and start thinking in:
- Architecture decisions
- Scalability
- Maintainability
- Feature boundaries
It was a great exercise in building beyond small demo apps.
If anyone is curious, here’s the live demo:

I’d be interested in hearing how others structure larger dashboard-style apps in Next.js.
