Cover image for Built a full-stack HRMS in

Features so far: Employee management with role-based access (Admin / HR / Employee) Leave request workflow with approval/rejection Attendance tracking — clock in/out, monthly calendar view Payroll engine — tax brackets, overtime, pro-rated salary, PDF payslip download Notifications, search, pagination, CSV exports Dockerized and deployed Stack: Next.js · TypeScript · Tailwind · FastAPI · PostgreSQL · SQLAlchemy The backend was a new challenge for me: SQLAlchemy relationships, Alembic migrations, Decimal precision for payroll calculations, streaming PDF responses — all of it was tricky at first, but I’ve learned a lot along the way. URL: https://lnkd.in/dRg86PtQ (https://lnkd.in/dRg86PtQ)This is just the beginning! I plan to add many more features.
