Human resource management
HRM System
ASP.NET Core 8 HRM GraphQL API—employees, attendance, leave, Hangfire payroll jobs, SQL Server/Dapper.
The challenge
HR teams needed a production-shaped API for employees, attendance, and leave—with a path to scheduled payroll—without waiting on a full UI suite in the first backend release. Without a coherent human resource management foundation, HRM System stakeholders faced fragmented tools, slow handoffs, and limited visibility—classic failure modes Tekvers designs against.
The solution
HRM System: ASP.NET Core 8 HRM GraphQL API—employees, attendance, leave, Hangfire payroll jobs, SQL Server/Dapper. Centralized HR API for employee, attendance, and leave operations. Tekvers delivered a maintainable human resource management system for HRM System using ASP.NET Core, HotChocolate GraphQL, SQL Server, Dapper, with phased rollout, operator workflows, and documentation suited to long-term ownership.
Approach
GraphQL-first HR domain
Employee, department, attendance, and leave operations were exposed through HotChocolate so future web/mobile clients share one contract instead of inventing parallel REST CRUD for every screen.
Attendance and leave workflows
Clock-in/out, approval, and attendance reports support daily ops; leave mutations cover request, approve, and cancel—keeping the highest-friction HR workflows in the API even where some SP scripts remain incomplete in-repo.
Background payroll and ops tooling
Hangfire runs monthly payroll processing and related schedules; Serilog, `/health`, Swagger (Development), and Docker Compose support operations—while documenting auth gaps (e.g. Hangfire dashboard not authenticated) honestly for hardening.
Deliverables
- ▸ASP.NET Core 8 HRM API (`net8.0`)
- ▸HotChocolate GraphQL endpoint at `/graphql`
- ▸REST auth: login and register (JWT)
- ▸Employee GraphQL queries and create/update/delete mutations
- ▸Department read queries
- ▸Attendance clock-in/out, approve, and report queries
- ▸Leave request / approve / cancel mutations
- ▸Payroll service with Hangfire monthly processing job
- ▸SQL Server schema scripts and Dapper stored-procedure data access
- ▸Docker Compose for API + SQL Server
- ▸Serilog logging and `/health` checks
Outcomes
- ▸Centralized HR API for employee, attendance, and leave operations
- ▸Scheduled payroll processing path via Hangfire
- ▸Containerized backend ready for client UI consumption
- ▸Clear honesty notes on tenancy enforcement and incomplete SP/doc surfaces
Impact
HRM System gives organizations a GraphQL-backed operating model for core people workflows—faster API integration for internal tools, better structure than spreadsheets, and a stack ready for a first-party UI or ERP embedding in a later phase.
