Projects

Software I’ve Built

Alongside my systems-engineering work, I build desktop software born from real field needs. Both applications below are actively used in production today.

Laundry Plus — Barcode Laundry Management Software

Laundry Plus is barcode tracking software I developed for industrial laundries washing hotel textiles. It digitizes the whole flow from label printing to bagging and delivery: every package is tracked by barcode, so bags sent to the wrong client, manual counting errors and lost-item disputes disappear.

Barcode label & bag tracking
Daily / monthly reports
Admin–operator separation
Automatic backups

With a touch-friendly interface and an offline-capable design, this laundry management software fits into a laundry’s daily workflow within minutes.

Service tracking system — plate-based smart vehicle check-in screen

Low2Garage Service Tracking System

A vehicle service tracking system I built for Low2Garage, an independent Land Rover specialist in Istanbul: plate-based smart check-in, model-specific maintenance packages, technician tracking on tablets and a digital service report e-mailed at delivery — all under one roof.

Paper job cards are gone: every step from check-in to delivery is recorded, and no vehicle leaves before management approves the pricing.
