Before the data, there was the field. Sasha brought merchants onto international marketplaces and sold off their overstocks — the raw reality of e-commerce, with its constraints on margins, inventory and listings. That experience shaped a core conviction: a strategy is only worth something if it solves a real problem and delivers measurable results.He now carries that standard into digital marketing through his consultancy Dotsland: campaign architecture on the Google Marketing Platform (SA360, DV360, CM360), server-side tracking and CAPI, cross-channel attribution and GDPR-compliant consent. Certified expertise, but above all hands-on — from strategic framing through to execution.That's the DNA of Datafirefly: pragmatic answers to problems encountered in the field, not theoretical concepts.

Understand the problem because you've lived it, then ship the tool that solves it at scale.Certified Google SA360 · DV360 · CM360 · Data Analyst · Generative AI · Didomi (GDPR) · HubSpot — Master's in Strategic & Operational Digital Marketing
