Computer vision quality control

FSIP intern 2022 · Management Trainee, R&D 2024 · Karachi

Two separate engagements, two years apart. The Golden Key came out of the first; the quality-control system out of the second.

The Golden Key, 2022

Dawlance runs FSIP, a competitive internship programme. Five interns from each intake are selected for the Golden Key: a PKR 200,000 award and a job offer on graduation. I was one of them in 2022.

The Golden Key. FSIP runs under Arcelik's freshstart early-careers brand; Arcelik rebranded globally as Beko in 2024.

Quality control on the line, 2024

I returned in July 2024 as a Management Trainee in R&D, on a separate intake from the 2022 internship. Everything below is that engagement.

In R&D I built an automated quality-control system on a Raspberry Pi using OpenCV. It replaced a fully manual inspection process and brought inspection time from four minutes down to under thirty seconds, cutting the effort involved by around 60%.

The inspection step running on a sticker image: text is segmented, each segment is scored for sharpness, and the run ends on a single clear or blurry verdict.

The hardware

AC lab data

I also rebuilt how AC lab data was extracted, pulling failure trends from three separate sources into one dashboard. That saved roughly ten hours a week and raised defect accuracy by about 25%.
