Finding the gem
in the data.
Business intelligence built on operational reality

Raw ERP data is like rhyolite — dense, complex, and full of structure most people never see. I build reporting tools and dashboards that surface what matters: cost variance, production risk, inventory exposure, and operational bottlenecks.

Specializing in Microsoft Business Central, Power BI, and the full procurement-to-production data chain.

Component intelligence
Challenge
Engineers and planners need to know not just where a component is used, but how much risk it carries — stock levels relative to open production demand, and what it costs the business if they can't be met.
Solution
Connects each component to its parent assemblies, open production orders, and inventory position. Static where-used data becomes a dynamic view of component criticality and financial exposure.

Alluvial
Demand forecasting
Challenge
Drop shipments flowing direct from country of origin created a distorted demand signal — making it difficult to get an accurate picture of true item demand across the business.
Solution
Reconciles warehouse and direct ship demand into a single combined view with year-over-year trend analysis, trailing averages, and lead-time-adjusted safety stock calculations.

Routing efficiency & BOM cost impact
Challenge
Standard costing assumes production runs at expected routing time — but small batches inflate variance because setup time dominates, and actual inefficiencies stay hidden in the data.
Solution
Separates run time variance from setup time impact by production run, with a what-if panel showing how routing adjustments ripple through to standard cost in the BOM structure.

FIFO cost layer analysis
Challenge
After transitioning to FIFO costing, item charges arrived weeks after receipt and adjusted layer costs retroactively. Tariff volatility created cost spikes in specific layers — invisible to Sales until margin collapsed.
Solution
Surfaces every open FIFO layer with its full adjusted cost composition, ages layers into 30/60/90+ day buckets, and simulates which layers a sales order will consume — flagging margin risk before the order ships.

About
Why Rhyolite?

Rhyolite is a volcanic rock formed when complex, silica-rich material cools slowly into something intricately structured. Inside it, under the right conditions, you find red beryl — one of the rarest gemstones in the world, hidden where most people would never think to look.

That's the work I do. ERP systems like Business Central generate enormous amounts of raw operational data — production orders, value entries, routing lines, ledger entries. Most of it sits unexamined. I build the tools that find what's valuable in it.
