Stack
How I build tests
Tools are the means. Knowing when — and when not — to use them is what actually matters.
Experimentation
Adobe Target · Monetate
Client-side & server-side. VWO and Optimizely when the stack calls for it.
Core tools
30+ tests
Implementation
GTM · JS · SDK
HTML/CSS/JS via Visual Composer and custom code. Clean, encapsulated, reversible variants.
Analytics & data
GA4 · Adobe Analytics
Mixpanel, data layer auditing. Events defined before the test runs — always.
Statistics
Rigorous by default
Power analysis, MDE, SRM checks, confidence intervals. Bayesian or Frequentist depending on context.
No early wins
CMS / Web
Framer · WP · React
WordPress, Squarespace, React component reading and modification. No flicker. Core Web Vitals protected.
Any stack
Industries
SaaS · Travel tech Experience
Enterprise B2B with long buying cycles. Travel tech with unpredictable seasonal traffic.
High complexity
Real stakes
