Two ID cards per A4 sheet, straight from ERPNext
A print format that turns ERPNext employee records into finished, front-and-back staff ID cards — two to a sheet — with no external design tool in the loop.

The network is slow
Users in one building report intermittent latency while the main internet link remains online.
What should be established first?
Diagnostic principle
Preserve evidence, reduce the fault domain, and make one justified change at a time.

Your network is slow, and it's probably not the fibre
A short field note on why latency complaints in a large network almost never point at the fibre — and the order I actually check things in.

The invoice pile that was being retyped by hand
The commercial team re-keyed machinery and vehicle line items from a folder of scanned invoices into a Word template, one PDF at a time. A Windows batch tool reads each PDF, keeps only the qualifying items, and exports a finished invoice named by its BOE number — with an AI fallback for the scans plain text can't reach.

ID cards two languages had to agree on
ERPNext prints documents, not cards. A Jinja print format that puts two bilingual employee ID cards — front and back — on a single A4 sheet, at dimensions a guard can check at a gate.

Bringing a 1,200-acre industrial park online
No fibre to the door, no single satellite link fast enough, and CCTV plus point-of-sale data to move from factories to head office. Eight Starlink terminals aggregated into a fibre distribution layer.

Eight thousand HR records, and who can reach them
HR needed one system for employee records, asset assignments, work cards and hostel allocations — real PII for 8,000 workers across four offices. Built on ERPNext, kept off the public internet, with administrator access gated behind a VPN on the MikroTik router.
- Case studies
Finding a fault that was not where everyone was looking
In a park this size, “the internet is slow” almost never means what it says. Fibre barely adds latency; the fault is a dirty connector, a failing SFP, a switching loop, a bent cable. A method for diagnosing by layer instead of by the loudest guess.

The reality of foreign-owned workplaces in Africa
Foreign investment across Africa brings real jobs and real skills — and real hardship. An honest look at both sides, and why the debate that matters is about power and accountability, not nationality.
