Enterprise Candidate Hiring Platform
Hiring systems for one of the world's largest retailers: a QR-coded document-attachment design the client chose over a planned manual team, and a later background-check cost redesign projected to save about $4M a year.
Store associates needed to attach signed candidate documents to each candidate's record, but store machines were terminals with no way to scan and upload. The planned answer was manual: scan forms to a shared inbox and have a 10-person team attach them by hand, against about 450,000 peak-season hires, with the risk of attaching a background-check document to the wrong candidate. After go-live, every background check still ran through a third-party vendor at about $13 per candidate.
I redesigned the printed form to carry a QR code identifying the candidate, with an ASP.NET batch job polling the shared inbox every five minutes, reading the code, and attaching the form to the right record. The assigned architect preferred the manual path; I built a proof of concept, took the case to the delivery manager, and we put both options to the client. After go-live, unasked, I researched the background-check vendor, found it was built on a Social Security Administration service the client could access directly, and designed a direct integration with modified API contracts plus the compliance operating model it required. I also owned architecture, coding, and non-functional reviews for the secure, distributed background-check solution and the encryption services across the hiring systems.
Delivered: the client chose the automated design and funded it, about $500K over 11 months; it replaced the planned 10-person team and removed the mis-attachment risk, saving at least 1,000 hours a year by my minimum estimate. Projected: the background-check redesign cut the per-candidate cost from about $13 to about $4, roughly $4M a year across about 450,000 hires. It went live under another contractor per the client's vendor policy, and I did not see post-launch numbers.
The $4M is the largest number in this portfolio and it needs its label: projected from hiring volume and the per-candidate price difference, approved by the client, and never measured by me after launch. What I can say was delivered is the QR design, which the client chose over the manual plan and funded, and which removed both a standing team and a real compliance risk.
The QR story is also a lesson in persuasion. The proof of concept showed the design worked, but it did not persuade the architect who opposed it, because I argued the technology and his worry was his team’s lack of QR experience. Today I lead with the value for the person I am trying to convince and address their real objection directly.
The cost redesign was unprompted. The hiring system was live and working, and nobody had asked anyone to look at the background-check bill. Sustained proximity to a running system is what surfaces the high-cost processes that internal teams stop seeing. What I would do differently is agree a measurement with the client before launch, so the saving is proven rather than projected.
