Demos don't ship. Dashboards don't decide. I build the systems that do.

I am an industrial engineer who spent fifteen years on the floor before writing a line of production code. Today I own master data in Dynamics 365 Business Central at a regulated producer in BC, where a data error is a regulatory event, not an ugly chart. I build the data, the analytics and the automations your operation actually runs on. Shipped, tested and working. Not a pilot.

Two services. Boring on purpose.

I don't sell «AI transformation». I sell two concrete things: data your operation can trust, and a supply chain that stops leaking money.

Business Central · Master data & analytics

Master data, BOM configuration, routings, MRP readiness and migrations in Dynamics 365 Business Central. This is the critical, tedious work partners subcontract, because it is easy to get wrong and expensive when it is. On top of it, the analytics layer: Power BI, SQL and Power Query models that turn clean data into decisions your team trusts. I do this every day inside a Health Canada regulated environment, where the data has to be right.

Supply chain

Planning, inventory and operations analysis for plants and distributors that grew faster than their processes. Bottleneck diagnosis, inventory sizing, S&OP readiness and flow redesign, backed by an MSc in Logistics and the ISCEA certification. I turn fifteen years on the floor into models your planners actually use, not spreadsheets they quietly ignore.

Koci Lead System

A renovation contractor in Vancouver was invisible to the exact people most likely to hire him: someone who just bought a condo with a dated bathroom. So I built the machine that finds them and shows them their own bathroom, already renovated.

In production

From MLS listing to mailbox, automatically

The system watches recently sold condos in Metro Vancouver, filters those matching the ideal client, takes the real bathroom photo, re-renders it as a finished renovation preserving the real geometry (walls, windows, plumbing), builds a two-tier priced flyer and mails it physically to the new owner. Every send passes human approval.

Rimex Invernaderos · Full ERP (ASP.NET + SQL)

ASP.NETSQL ServerERPBOM / ProductionInventoryAP / AR

An end-to-end ERP I built for a greenhouse manufacturer on ASP.NET and SQL Server. The whole company ran on it: inventory, purchasing, administration, BOM and production, plus accounts payable and receivable and greenhouse-project progress. One connected system, one version of the truth, every department on the same data.

n8n job-posting automation

n8nScrapingNotifications

An n8n workflow that scrapes new job postings and fires notifications on its own. The kind of small, reliable automation that quietly deletes a daily manual chore. Built and running.

I spent fifteen years in operations before I wrote a line of production Python. That order matters. I know what a wrong BOM costs, what a stockout does to a plant, and why a floor supervisor does not care about your model architecture.

Today I own master data governance in Dynamics 365 at a licensed cannabis producer in BC, where a data error is a regulatory event, not just an ugly dashboard. On my own time I build data and automation systems for businesses that want results, not decks.

What's your bottleneck?

If it's data quietly breaking your ERP, or a supply chain leaking margin, those are the things I fix. Tell me the bottleneck. If I am the right person, I will show you how. If I am not, I will point you to who is.
