Case study · 2024 – Now
SIHRIS
An HRIS for attendance, shifts, time off, overtime and payroll. I built user and device management with audit logging, and sped up the Time Off and Overtime modules.

Context
SIHRIS is an HR information system covering attendance, work shifts, time off, overtime and payroll. I joined it as an intern in 2024 and have kept working on it as a freelance fullstack developer.
What I built
- User and device management with structured activity logging, so audits and troubleshooting have something to go on.
- Faster Time Off and Overtime modules through query optimisation, database indexes and less duplicated code.
- Payroll components.
- Announcements, notifications and UI fixes during my internship.
