Full-Stack Business SoftwareFeatured

HR Operations Platform

HR work is business software that has to be more than a pretty dashboard. The system needs roles, records, approvals, mobile access, reporting, policy documents, and a backend that can evolve without turning into disconnected tools.

The Challenge

HR teams need one reliable place for employee records, attendance, leave, payroll, policy documents, and reporting. When that work is split across spreadsheets, chat, paper records, and separate tools, status visibility and approvals become slow and fragile.

The Solution

I structured the product as a Bun-based modular monolith with a NestJS GraphQL backend, React admin portal, and Expo mobile app. The system separates core HR domains while keeping deployment and development practical for a smaller team.

Key Features:

Authentication and account provisioning

Company settings, departments, and designations

Employee management and location assignment

Geofenced attendance workflows

Leave balances, requests, and approvals

Payroll setup, processing, and payslips

Policy document management

Live reporting dashboard

The Impact

This is the strongest portfolio proof because it shows ordinary, valuable software engineering: backend architecture, admin UX, mobile workflows, database-backed records, reporting, and business logic that maps to real operational work.

Buyer Pain

The buyer needs a practical HR system that replaces fragmented admin work with one source of truth for people, attendance, leave, payroll, documents, and reports.

Workflow

Before

Employee data and HR actions spread across spreadsheets or separate tools
Attendance, leave, payroll, and documents require manual reconciliation
Managers need manual follow-up to understand current status
Reporting depends on cleanup rather than reliable source data

After

Admin provisions companies, departments, roles, and employee records
Employees use mobile-facing flows for attendance and requests
Managers review approvals, balances, documents, and reports
Payroll and policy workflows stay tied to the same HR data model
Operational reports pull from the system instead of ad hoc cleanup

Architecture And Proof

Architecture

Bun workspace with NestJS GraphQL backend, React admin portal, and Expo mobile app
Modular monolith structure to keep HR domains clear without microservice overhead
PostgreSQL-backed runtime with Docker Compose for local development
Separate web-admin and mobile surfaces over shared backend workflows

Proof

Vault catalog marks this as an active work/client project
Repository README documents backend, web-admin, mobile app, Docker, and Bun workflow
Implemented module list includes auth, employee management, attendance, leave approvals, payroll, policies, and reporting
Verification commands are documented for backend build, web-admin build, mobile typecheck, and backend tests

Tradeoffs And Business Value

Tradeoffs

A modular monolith is easier to ship and operate for a bounded HR platform
Anonymized portfolio framing protects work context while still showing the engineering shape
The case study avoids fake adoption metrics until measured proof is available

Business Value

Replaces scattered HR admin work with a single product workflow
Improves visibility across attendance, leave, payroll, policy, and reporting data
Shows the ability to build useful business software across backend, web, and mobile surfaces

What This Proves

I can build full-stack business software that handles real records, roles, workflows, mobile use cases, and admin reporting without needing AI as the main selling point.
