Human Resource Management System (HRMS)

Project Overview Designed and developed a comprehensive Human Resource Management System (HRMS) to streamline employee management, attendance tracking, leave requests, payroll administration, performance evaluation, and internal communication. The platform consisted of a responsive web application for administrators and HR personnel, alongside a cross-platform mobile application for employees. The system was built with a scalable architecture to support organizations ranging from small businesses to large enterprises, emphasizing security, maintainability, and high performance. Responsibilities System Architecture • Designed the overall system architecture, including frontend, backend, database, authentication, and deployment strategy. • Planned scalable database schemas and optimized relational data models. • Implemented secure role-based access control (RBAC) for multiple user roles. • Designed RESTful APIs with proper validation, pagination, filtering, and error handling. Web Development (Next.js) • Developed a responsive HR management dashboard using Next.js, TypeScript, and Tailwind CSS. • Built reusable UI components and scalable frontend architecture. • Implemented employee management, department management, and organizational hierarchy. • Developed dashboards with interactive charts, analytics, and KPI reports. • Created advanced filtering, searching, sorting, and bulk operations for employee records. • Implemented server-side rendering (SSR) and client-side optimizations for improved performance. Backend Development (Supabase) • Designed PostgreSQL database schemas using Supabase. • Developed secure APIs using Supabase Edge Functions. • Implemented authentication with email/password and OAuth providers. • Configured Row Level Security (RLS) policies for fine-grained data access. • Built real-time features using Supabase Realtime. • Developed database triggers and scheduled jobs for automated workflows. • Optimized SQL queries and indexes to improve system performance. • Implemented file storage for employee documents, contracts, and profile images. Mobile Development (Flutter) • Developed a cross-platform mobile application for iOS and Android using Flutter. • Implemented secure authentication and biometric login. • Built employee self-service features including: o Attendance check-in/check-out o Leave requests o Payroll viewing o Personal profile management o Company announcements o Push notifications • Integrated offline caching and automatic synchronization. • Optimized application performance across multiple device sizes. HR Features • Employee onboarding and offboarding. • Department and organizational structure management. • Attendance and timesheet management. • Leave request and approval workflow. • Payroll management. • Performance review management. • Employee document management. • Company announcements. • Holiday calendar. • Shift scheduling. • Role and permission management. • Audit logs for sensitive operations. Security • Implemented JWT authentication. • Configured Row Level Security (RLS) in Supabase. • Enforced secure API authorization. • Protected sensitive HR data using encrypted storage. • Implemented audit logging for administrative activities. Performance Optimization • Optimized database indexing and query performance. • Reduced API response latency through query optimization. • Implemented pagination and lazy loading. • Optimized frontend rendering and asset loading. • Improved mobile startup time and scrolling performance. DevOps & Deployment • Configured Docker-based deployment environments. • Automated CI/CD pipelines using GitHub Actions. • Managed production deployments with Nginx reverse proxy. • Configured SSL certificates and environment management. • Implemented centralized logging and monitoring. • Automated database backups and recovery strategies.
