ANDREI CAZACU
I'm Andrei Cazacu, OT Architect. I work with manufacturers who've committed to digitalization and need someone who can own the architecture, drive the delivery, and make it stick across the business.15 years. 6 industries.
FMCG · Pharma · Automotive · Oil & Gas · Warehouse Automation · IntralogisticsMost digitalization programmes start with ambition and end with a pilot that never scaled.Not because the technology failed.Because no one owned the architecture end-to-end, the layer where shop floor meets IT, where vendor promises meet operational reality, where a 3-year roadmap meets a plant manager who needs results this quarter.That's the gap I close.
I come in as a Fractional or Contract OT Architect, senior-level strategic and technical leadership, engaged at the point where it matters most.I've deployed MES across 12+ production lines at Unilever, led IIoT architecture across global pilot plants at Mondelez, and built automation systems that scaled from prototype to production at Ocado.I don't consult from a distance.I work inside your programme with your engineers, your IT team, your leadership until the architecture is sound and the delivery is moving.Remote-first. EU · UK · US. Available for up to 20% on-site when it counts.SERVICESThree ways to engage:① Factory Intelligence Assessment
2–4 weeks · Remote or on-site · Fixed scopeFor manufacturers who suspect their OT stack is holding them back but aren't sure where to focus.I conduct a structured evaluation of your automation, control, and data architecture, then deliver a clear picture of where value is being lost and exactly what to do about it.You leave with: a prioritised gap analysis, a phased digitalization roadmap, and vendor-neutral recommendations your team can act on immediately.The right starting point before any significant OT investment.② Fractional OT Architect
3–12 months · Part-time embedded · Remote + travel when needed.For organisations that need senior OT architecture leadership without a full-time hire.I work as part of your team, owning the OT architecture layer, aligning IT and operational stakeholders, guiding vendor selection, and ensuring delivery decisions are made with the full picture in view.Typical engagements cover: IIoT platform design, MES scoping and rollout, IT/OT convergence strategy, cloud and edge integration, and multi-site standardisation.The model that gives you architecture thinking at fractional cost.③ Programme Recovery
Engagement-based · Mobilisation within 2 weeksFor leadership teams whose OT or MES programme has stalled over budget, behind schedule, or simply not delivering what was promised.I come in, diagnose what broke and why, reset the architecture and delivery model, and stay until the programme is back on track and your team can own it going forward.No politics. No blame. Just a clear path forward.Built for the conversations that need to happen before a board escalation.

The gap in most OT programmes isn't technical skill.It's someone who can hold the architecture and the business case at the same time.I've worked at every layer of industrial digitalization, PLC code to cloud architecture, commissioning floor to CAPEX justification.I know what vendors oversell, where integrators cut corners, and how to build a roadmap that survives contact with a real factory.What that means in practice:
Your programme moves faster because decisions get made with confidence, not committee.Your vendors are held to a standard.Your internal team builds capability alongside delivery, not dependency on the next consultant.And when I leave, the architecture is yours: documented, transferable, and built to scale.Mondelez · Unilever · Ocado · Renault · Powder Systems · AIDA Engineering

I work with a small number of clients at any one time.If your programme is stalled, your OT architecture needs senior ownership, or you're planning a digitalization investment and want it done right the first time, this is the right conversation to have early.Remote across EU, UK, and US. On-site available where it matters.
