In today's data-driven world, businesses continually seek innovative and efficient ways to scale and gain a competitive edge. Through her exceptional analytical capabilities, her talent for turning data into insights, and her unique ability to integrate data strategy with business objectives, Aksinia is transforming the digital landscape and helping high-growth companies reach new heights.
Chumachenko began her journey with academic and early career foundations rooted in analytical thinking and digital strategy. Her roles at renowned organizations such as Sberbank CIB, Renault Group, and Ozon Fintech enabled her to master data analytics tools rapidly. She helped create the analytics backbone for fintech services like OZON Card and OZON Invest, influencing decisions at the C-suite level.
She further honed her leadership at BCS World of Investments, where she launched the firm's first A/B testing infrastructure. Through a series of experiments, she improved mobile onboarding conversion by 8% and cut time-to-purchase for mutual funds by 50%.
More recently, Aksinia's exceptional data analytics expertise has had a direct and tangible impact on Simpals' growth and its diverse portfolio of digital platforms. For example, at 999.md, Moldova's most visited website with over 300,000 daily visitors and approximately 2.2 million unique monthly users (representing a remarkable 88% of Moldova's internet-using population), Aksinia has been instrumental in driving key product improvements.
Joining in 2021 as the first product analyst at 999.md, she built the analytics ecosystem from scratch, establishing event tracking, A/B testing systems, and PowerBI dashboards. The results of her work have led to a promotion to a Team Lead Product Analyst and expansion of the analytics team.
Under her leadership as Team Lead Product Analyst, Chumachenko:
- Scaled the analytics team from one to seven members across multiple verticals.
- Drove a 2x increase in spending by key business clients through personalized support and data-driven account strategies.
- Improved seller-buyer contact rates by 10% through strategic metric design.
- Reduced data storage costs by 3x via Google BigQuery optimizations.
Perhaps most impressively, her cross-product research initiatives resulted in a 7% increase in views and a 5% revenue growth for key paid services, alongside a 1.25% increase in total product revenue.
"I've learned to be resourceful—when you don't have all the tools, you build your own. That's exactly what I've done in analytics."
By deeply understanding each product's data, market niche, and target audience, she crafts analytical strategies that resonate, establishing the brand as an authority while achieving tangible business outcomes. Currently, Aksinia is managing the analytics for 6 of Simpals' products, including Point.md and Știri.md. They are one of the most visited news websites in the Republic of Moldova. She also works with Afisha, Moldova's leading platform for purchasing event tickets.
Aksinia's ability to maximize impact while minimizing resources has not only saved Simpals time but also established its platforms as trusted authorities in their respective fields. One of the ways she continues to push the boundaries of data analytics is by integrating cutting-edge methodologies and technologies into her workflows.
"In data analytics, if you're not evolving, you're falling behind—I'm always learning, experimenting, and challenging my team to do the same."
Her articles on A/B testing, including "Improving and Speeding Up A/B Testing" and "Working with Ratio Metrics in A/B Testing," demonstrate her deep understanding of this crucial methodology for optimizing digital products and user experiences. Aksinia's work in this area offers valuable insights into designing and implementing practical A/B tests, accurately analyzing the results, and utilizing the findings to drive meaningful improvements.
Her article, "Methods of Classification and Clustering in Data Analysis," further showcases her broad expertise in data analysis techniques. Classification and clustering are fundamental tools in data science, used to categorize data points into groups based on their characteristics. This article demonstrates Aksinia's understanding of the theoretical underpinnings of these methods and their practical application in solving real-world problems.
Aksinia is committed to expanding her impact even further. "My goal is to drive both innovation and growth by making data analytics smarter, more intuitive, and more aligned with business goals," she says.

She's also a mentor in the WomenTech Network's "Women in Tech" program, helping equip the next generation of female technologists with the skills and confidence to thrive in data science and analytics.
She was also a judge at Technovation Girls Moldova, an international program that supports girls in tech. Her role was also to lead one of the teams from the concept and strategy stages through to the realization and financial planning of their product.
