One System for the Entire Employee Lifecycle: Inside Our HR Management System

From the moment a candidate applies to the day a payslip lands in their account, HR touches almost every part of a company — and most teams stitch that journey together across four or five disconnected tools. We built an HR Management System that carries an employee through the whole lifecycle in one place, and it's live as an interactive demo.

Five Modules, One Employee Record

Module	Purpose	Key Features
Core HR & Records	Centralizes employee data and organizational structure	Digital employee files, org charts, document management, role-based access
Recruitment & ATS	Manages hiring pipelines from sourcing to offer	Job postings, candidate pipeline, interview scheduling, offer stage tracking
Time & Attendance	Tracks working hours, schedules, and leave	Clock-in/out, PTO workflows, overtime calculation
Payroll & Compensation	Automates salary calculations and disbursements	Statutory tax withholding, bonus calculations, benefits deductions
Performance & Talent	Drives employee development and retention	Goal tracking (OKRs/KPIs), performance reviews, skill tracking

Every module shares the same employee record — a candidate hired through the ATS becomes an employee in Core HR without re-entering data, and their salary flows straight into payroll the moment they're active.

A Tour of the System

Command Center Overview

One glance answers the questions HR gets asked daily: how many active employees, how many candidates are mid-pipeline, how many leave requests are waiting on a decision, and which goals need a check-in because they're at risk.

Core HR & Records

A searchable employee directory with auto-generated employee numbers, an organization chart built live from manager relationships (no separate diagramming tool required), role badges that stand in for access level (Admin / Manager / Employee), and a document panel for contracts, ID proofs, and certifications.

Recruitment & ATS

Post a job, add candidates, and watch them move through a Kanban pipeline — Applied → Screening → Interview → Offer → Hired — with interview scheduling built in, so recruiters and hiring managers work off the same board instead of a shared spreadsheet.

Time & Attendance

One-click clock-in and clock-out per employee with automatic hours and overtime calculation, plus a PTO/Sick/Unpaid leave workflow that a manager can approve or deny in a click — backed by a running attendance log.

Payroll & Compensation

Generate a payroll run for any period and the system calculates gross pay from each employee's annual salary, applies statutory tax withholding and the standard benefits deduction, and produces an itemized payslip per employee — ready to mark paid and disburse.

Performance & Talent

Set goals with a progress bar and status (on track / at risk / completed), and log performance reviews with a star rating and written feedback — everything a manager needs for an annual review conversation, in one place.

How It's Built

• Vue 3 (Composition API, <script setup>) + TypeScript + Vite
• Tailwind CSS v4 on our design system tokens
• SQLite running entirely in the browser via sql.js — employees, candidates, leave requests, attendance, payroll runs, and reviews all live in real relational tables
• Data persists locally between visits, with a one-click Reset demo data button

Try It Yourself

Register an employee, move a candidate through the hiring pipeline, clock someone in, approve a leave request, run payroll and expand the payslips, then set a goal and leave a review — the full employee lifecycle, end to end.
