ABOUT TATIANA SELL

ImpactAs a business operations and continuous improvement leader, I’ve generated $40M+ benefit, 200K+ hours in efficiency gains, and consistently achieved 90%+ on-time, on-budget delivery. I’m passionate about enhancing customer and employee experiences by optimizing and transforming processes. My approach blends Lean Six Sigma (LSS) expertise to deliver data-driven solutions that reduce waste and solve complex business problems, experience in software development and AI implementation to automate, simplify, and standardize workflows, and rigorous Program Management to ensure disciplined execution of a portfolio of initiatives. HighlightsI led the delivery of a zero-to-one SaaS platform that revolutionized rental tax compliance for Uganda’s Ministry of Finance in Africa; drove Lean transformation and multi-million savings at Intuit in the US; and spearheaded change management initiatives to accelerate Lean adoption at Volkswagen in Brazil. ExperienceTwo decades leading cross-functional initiatives across five continents, partnering with startups and Fortune 500 in fintech, technology, retail, med-tech, automotive, and government. I’ve worked in both consulting and corporate roles from Chief of Staff to a COO, where I reported outcomes directly to investors, to coaching frontline managers in structured problem-solving, performance management, and change leadership. Leadership StyleI lead with purpose, combining collaboration, a relentless pursuit of excellence, data-driven prioritization, and disciplined execution. I believe small, well-executed improvements can be just as powerful as large-scale transformations. I promote a “right-first-time” philosophy and accountability for quality outcomes. I build trust based on follow-through, operate with transparency, avoid politics, empower others to succeed, and always share credit where it’s due.
