Six accounts in detail.
Tech-E
1,591 shipments into 119 fulfilment centres, 83 factories mapped, 857 SKUs under weekly instruction.
Wargames Delivered
The stock was sellable on day 9. The card was not paid until day 86. That is 77 days of stock financed after it could have sold.
Coda Music
122,263 units reconciled to zero error rows, and supplier minimums that more than doubled the purchase order.
Zesti Greens
Four nodes read separately, two forecasts kept side by side, and 28 of 44 ASINs called short in the first week of November.
Skyve
54 inbound shipments across 15 months, with ocean and rail priced against each other per product and per country.
HODL-21
166 purchase orders tracked to the line, with the time from order to receipt measured on every closed one.
Nine more, one line each.
Four systems, four SKU schemes, 204,665 units into one catalogue. The reconciliation surfaced 17,621 units across 83 SKUs with no mapping at all.
Thirty returned scooters worth $65,021.25 at landed cost, triaged one serial number at a time, each repair leaving with a named part SKU and a priced parts bill.
A 247-PO, 39-supplier, four-country operation given a spine, and its third-party logistics bill rebuilt into a cost model across 1,871 orders and 94 SKUs, with the actual rate card extracted: EUR 1.25 per order plus EUR 0.42 per item picked.
A three-region fulfilment operation on a brand selling $65M a year, documented as 288 procedure items, including a 147-step region and box-type checkpoint matrix.
A 120-product catalogue rebuilt into 32 structured SKU families. Forty-one percent of it had no usable SKU beforehand.
A fifteen-month influencer seeding programme audited end to end. Of 105 tracked shipments, 46.7 percent had no content ever logged against them.
A China to United States fulfilment model across three freight modes, two SKU weights, two minimum-order tiers and four scenario blocks.
Thirty-five purchase orders placed through AS400, fifty SKU-enrichment quality checks before products went live.
Customs classification written down as a rule set: knit against woven decides the chapter, majority fibre by weight controls, shell only.

What clients actually wrote.
Thirteen clients left written reviews on the platform record. Five are here, in full or with an ellipsis where a sentence was cut.
“Hired him for a demand forecasting project, historical sales analysis, trend and seasonality identification, SKU-level projections, all built in Google Sheets. He came in fast, asked the right questions upfront, and the model he built was clean and actually usable by the team, not just impressive to look at. I first worked with him about a year ago on a similar scope and had a good experience. This confirmed it wasn’t a fluke. If you’re looking for someone who understands the operational side of inventory and purchasing, not just the spreadsheet mechanics, he’s worth the conversation.”
“Hamza has been a major lever in our business. He plays a critical role across supply chain operations, packaging development, dielines, and overall project management, while also effectively managing and coordinating the team. He brings structure to complex workflows, keeps projects moving forward, and consistently delivers under pressure … someone we trust with core parts of the business.”
“Hamza is really great with data, I personally like his way of understanding the system and going deep into it to find the gaps and then providing solutions for them. He is easy to work with and has a great sense of humour. I would definitely rehire him for my next project.”
“Great operational mindset. The recommendations were practical and clearly prioritized. Their coordination, focus, and ownership were outstanding. Each part of the work was handled by someone who clearly knew what they were doing, and communication was seamless.”
“Very good communication throughout the project. Helped find a reliable 3PL partner, negotiated effectively, and performed exceptionally well under pressure. Would definitely hire again.”
