From procurement to software.
I spent nearly eight years in procurement — first at an international trading company in Istanbul, then as purchasing coordinator and purchasing manager at a manufacturing plant in Romania — sourcing raw materials and packaging from China and across Europe.
That work showed me where operations really break: in the spreadsheet nobody trusts, the form retyped three times, the file only one person understands.
In July 2025 I moved from procurement into IT and started fixing those breaks myself.
LUMAISTRA S.R.L., founded in Ploiești in 2026, offers that method to teams that still run on paper and Excel — and builds apps of its own. It is one person, and that person is me.
How I work
- A dry run before any data change.
- Every figure traceable to a source.
- AI-built work always disclosed as AI-assisted.
Who I work with
Plants and offices in Romania that still run on paper and Excel — and anyone who needs a website or an app built properly.
What I won’t claim
- Hands-on experience with named ERP systems.
- A GDPR certification badge.
- Client testimonials I don’t have yet.

The name “LumAIstra”
Lum (light) · AI · stra (layers). The logo’s three layers and the line of light through them are the idea: make each layer of the work visible, so a person can see clearly before deciding. It’s a small company built on one person’s experience — when you work with LumAIstra, you’re working with me.
