About Konstantin Zhitkov
Senior Product Data Scientist at Wolt
Product Analyst with 8+ years of experience in HRtech and E-commerce. Currently I am a Senior Product Data Scientist on the consumer analytics team at Wolt.
I manage the full product analytics lifecycle: from building ETL pipelines in Airflow to the design and interpretation of complex A/B tests and metrics. I have passion for statistics and try to stay inline with industry trends by regularly diving into the latest research papers.
I played an active role in hiring at HeadHunter, where I conducted over 60 technical interviews (covering SQL, Python, A/B testing, and metrics) and successfully onboarded three colleagues into the interviewing process.
How I Can Help For Professionals Resume Optimization: I will analyze and refine your CV to ensure it stands out to top-tier employers.
Technical Mock Interviews: We can run a practice session focusing on SQL, Python, or A/B testing, followed by detailed feedback.
Curated Learning Paths: I can provide high-quality study materials to help you master A/B testing, SQL, and product metrics.
For Companies Hiring Support: I can design and validate technical assessments for SQL, general analytics, or A/B testing to help you identify top talent.
