Case studies
Three enterprise projects in integration, reporting and automation, one live system built and run by EthanCorp, a Power BI reference build shown page by page, and a reference architecture for an integration hub on Azure. Context, constraints, architecture, what was actually done, and the numbers — including the ones that are only approximately good.
01 Enterprise
Twenty-plus enterprise systems that each held part of the truth, connected into governed data flows with reconciliation built in — across twelve business units and five countries.
02 Enterprise
A five-day manual reporting cycle replaced with governed dashboards on standardised definitions — and the arguments about whose number was right replaced with one KPI dictionary.
03 Enterprise
A ten-step manual document workflow reduced to two guided steps, with an explicit human review gate — and the acceptance rate measured rather than assumed.
04 Live
A production RAG assistant answering iSAMS questions from a curated knowledge base, with an admin console, cost visibility and a feedback loop — free and open to the iSAMS community.
05 Reference build
A ten-page Power BI reference build for SenMinh Education Group, a group of seven international schools. It tells the board, the CFO and each principal what changed, why, and where to act — on synthetic data generated by a script, so every page can be shown in full.
06 Reference architecture
How a website, stores, a bank, ERP, CRM and reporting stay in step through one hub on Azure — three layers, each with one job, shown move by move in eight scenarios on fictional data.
Dat Tran — every one of these was designed and delivered by me, and where an AI assistant wrote the code, the case study says so. EthanCorp is a one-person consultancy, so there is no question about who did the work.
The fastest way to find out whether it transfers is a 30-minute scoping call. If it does not, you will hear that.
