A physics teacher reports in sick at 07:12. Four classes have nobody standing in front of them, the first bell is at 08:00, and cover gets arranged by phone calls nobody writes down. We build for those forty-eight minutes — and for the equivalent hour in a feed mill and on a loading dock.
Specified targets, not measurements. Nothing here has been shipped or timed.

Designed workflowBoth halves are true today. We build custom operational software for businesses here, and that work funds a product line of our own, for three industries where the same problems repeat at every organisation.
The same method sits under every one of them. Each product page states exactly where that product is.
Shadowing sessions with the person who owns the problem, at the hour the problem happens.
Separate what was asked for from what someone is trying to get done, and build for the second.
Each bet carries a measure and a falsification threshold, agreed before the build.
Sized for a 4 GB Android on a weak cell; capture works for at least 72 hours with no network.
Thirteen of them are written down, numbered, and traced to the requirement each one produced. Here are four, each with the way we intend to answer it.
By 08:00 a class or two is still unattended, and afterwards nobody can say who covered what — so the workload dispute cannot be settled and the substitute is neither credited nor paid.
Names are ambiguous in a country where many students share one. The bank statement arrives days later, arrears lists are stale, and reminders go to whoever is remembered.
It arrives late, and it arrives wrong, and both are discovered downstream.
Nobody notices for weeks, and the failure is discovered on the one day the recording was needed.
Illustrative. The register states these problems and never quantifies them, so the diagrams carry no numbers of their own.
Three industries, one platform underneath. Each product page states exactly where that product is, because none of them is finished.
Builds a school’s routine, dispatches a substitute teacher when one calls in sick, records attendance offline, and reconciles fees against the payment gateway’s own settlement report.
Captures field data inside a shed with no signal, tracks a production batch from placement to close, and settles contract farmers against records both sides can read.
Runs detection on a box at the site, sends events rather than video, and produces evidence a dispute can actually be settled with.
We have no customer logos to show you. What we have is the research the products were specified against — every figure with the publication it came from and the date it was published, so you can check it.
The buyer is a proprietor with their own cheque book. There is no tender and no committee procurement cycle.

BBS Private Educational Institutions Survey 2024, via UNB7 Apr 2026In-country hosting is colocation plus a self-managed database, not a managed-service purchase.
Provider region listings, checked23 Sep 2026Every figure carries its source and date. We would rather it be checkable than impressive.
Figures we could not verify independently — the widely repeated ones about hours lost to scheduling, spreadsheet usage and false-alarm rates — appear nowhere, because the requirements document that specified these products disowned them, and using them here would be worse than having no number at all.
Each of these costs us something, which is why they are worth more than a list of features.
The institution stays merchant of record. Aggregating payments is a licensed activity in Bangladesh — a trust and settlement account, T+5 settlement, about BDT 1 crore of capital, and personal liability for named officers. We orchestrate collection; we never sit in the flow of funds.
No independently audited figure exists for this class of system. We commit to the mechanism and to a baseline measured on your own cameras, at your own site. A percentage quoted before that is a claim about somebody else’s footage.
How many streams one box handles depends on resolution, frame rate, scene complexity and the accelerator fitted. Quoting it in advance is guessing with your capital.
Substitute ranking is rules-based, and payment matching is an honest exceptions queue rather than a probabilistic guess. A silent wrong match in a fee ledger is worse than a queue somebody has to work.
Most of what we do today is custom: a point-of-sale system, an inventory ledger, a CRM, a school office, a booking engine. Same method, same engineering standards, on a system that belongs to you rather than to us.
A constraint solver that explains why a timetable is impossible. Capture that survives seventy-two hours with no network. Money that reconciles three ways against the bank’s own settlement file. Isolation enforced by the database and proved by a test that runs the whole API suite as the wrong tenant.
Not a feature list — the thing that goes wrong on a Tuesday and costs somebody their morning. If we are the wrong people to fix it, we will say so, and we will usually know who is right.
