Who I am and how I create impact

I am a senior transformation leader and Lean Six Sigma Master Black Belt with more than two decades of experience delivering measurable impact in industrial, manufacturing, and life-sciences environments.

I work at the intersection of operations, data, and people systems. My approach is deliberately evidence-based: I form hypotheses, test them against operational reality, and translate validated insights into decisions, structures, and routines that hold up under pressure and over time. I am as comfortable working hands-on with data as I am aligning leadership around what the data actually shows.


Transformation contexts I have led in

I have led and delivered transformations in contexts where complexity is real and outcomes matter:

  • Regulated pharma and life-sciences operations, where improvements must be data-driven, audit-proof, and sustainable beyond individual leaders
  • Manufacturing and supply-chain systems, with a focus on end-to-end flow, variability reduction, and decision clarity rather than local optimisation
  • Enterprise production-system and operational-excellence programs, deployed across multiple sites with consistent governance and measurable results
  • Post-merger, scale-up, and turnaround situations, where legacy behaviours, informal authority, and urgency collide

Across all contexts, one principle applies: impact only counts if it can be demonstrated, explained, and sustained.


How I lead and work

My leadership combines statistical thinking, structured change leadership, and practical execution:

  • I lead hands-on, close to operations, while maintaining clear governance and decision rights at leadership level
  • I use data- and hypothesis-driven problem solving to separate signal from noise and avoid opinion-based decisions
  • I apply change-leadership principles from MIT, adapting my approach to the specific situation rather than following a fixed playbook
  • I am familiar with a broad range of improvement, change, and transformation tools — and deliberately select only what fits the context, maturity, and constraints of the organisation
  • I design operating models, routines, and metrics that make progress visible and repeatable
  • I build internal capability, ensuring results survive after programs and external support end
  • I challenge pressure for instant fixes by replacing urgency with disciplined, staged execution
  • I pay attention to informal authority and behavioural patterns, not only formal structures
  • I avoid initiatives that look convincing on slides but cannot be validated through data or sustained in daily operations

I measure success by what still works when attention shifts, leadership changes, or priorities move elsewhere.


Credentials that matter

  • Lean Six Sigma Master Black Belt, applied in large-scale, regulated, and multi-site environments
  • Change Leadership training at MIT, focused on leading transformation under complexity and uncertainty
  • Industrial Engineering background, grounding my work in systems thinking, data, and flow
  • Extensive experience across pharma, manufacturing, supply chain, and enterprise transformation contexts


A personal note

I care deeply about responsible leadership in environments where decisions affect people, safety, and long-term performance. I believe in treating data honestly, respecting system complexity, and leading change in a way organisations can sustain without heroics.
