Project overview
The context behindthe final result.
A closer look at the goals, decisions, and technical thinking that shaped the project.
TimePunch explores the architecture behind a practical employee attendance system rather than only the visible clock-in interface.
The application separates employee and administrative responsibilities while keeping authentication, API behavior, persistence, and caching organized for future growth.
Key features
What the projectneeded to accomplish.
Core capabilities delivered for TimePunch.
Clock-in and clock-out workflow
Employees can begin and end shifts while maintaining timestamped attendance history.
Attendance dashboard
A responsive React interface presents status, worked time, and prior shifts.
Administrative reporting
Administrative views support attendance review and payroll-oriented inspection.
Punch management
Authorized users can create, review, update, and remove punch records when corrections are required.
Structured persistence
Relational storage organizes users, shifts, and time-entry records.
Application workflow
From clock-in to attendance review
Employees record work sessions through a focused workflow while administrators review and correct attendance data through separate tools.
- 0101
Sign in
Employees and administrators authenticate securely.
- 0202
Clock in
An employee records the beginning of a shift.
- 0303
Track
The application stores and displays the active shift.
- 0404
Clock out
The employee records the end of the shift.
- 0505
Review
Administrators inspect records and manage corrections.

Selected screens and interfaces from the project.
Technical highlights
The systems behindthe interface.
Selected architectural and implementation decisions that shaped the project.
ASP.NET Core API
The backend exposes structured endpoints for authentication, employees, and punch records.
.NET Aspire
Aspire coordinates application services and development configuration.
React and TypeScript
The frontend provides distinct employee and administrative experiences.
Secure password handling
Authentication work includes password hashing and a foundation for token-based access.
Redis caching
Caching is incorporated where repeated application data can be served efficiently.
Relational data design
Users, shifts, and punch records are modeled with clear relationships.
Challenges
The difficult partsshaped the better decisions.
The constraints and implementation problems that required the most thought.
Separating access levels
Employee and administrative workflows needed clear authorization boundaries without duplicating application logic.
Maintaining punch accuracy
Time-entry rules had to account for incomplete sessions, corrections, and historical records.
Coordinating the application stack
Frontend, API, cache, and database services needed consistent local orchestration and configuration.
Future direction
Still evolving.Still worth refining.
