I build AI learning and developer onboarding products that improve activation and retention.
GermanyWhat I'm looking for
At JetBrains, I lead product strategy for an AI-powered learning agent that helps developers learn through guided, Socratic conversations. I launched its first external pilot and secured Early Access university partnerships representing approximately 1,000 students.
I drive AI product development end to end, from customer discovery and rapid prototyping to prompt engineering, LLM selection, token optimization, and agent workflow design. I also built an evaluation harness to compare OpenAI GPT, Google Gemini, and Claude across quality, latency, cost, and educational effectiveness.
Previously, I led JetBrains' Developer Onboarding Platform and created a three-year onboarding strategy that increased trial-to-paid conversion by 30% and improved retention among new users by 20%. I introduced funnel analysis, A/B testing, JTBD research, and regional localization for China, Japan, and Korea.
I began at JetBrains as a software developer, building automated UI-testing infrastructure for IntelliJ-based IDEs and a widely used learning plugin. My astronomy, physics, and computer science background shapes how I analyze large datasets and turn complex research into practical product decisions.
