Hi, my name is

Szymon.

I turn product chaos into business impact

I believe everything is buildable with the right “why”. I translate technical constraints and data insights into clear, actionable roadmaps, ensuring that every feature built moves the needle for the business.

About Me

With over 6 years in the digital product space, I’ve learned that the most successful features are those that solve real problems while moving business metrics. My background in analytics gives me a ‘data-first’ lens, while my experience in AdTech allows me to understand the complexities of modern monetization.

Currently, I’m driving product growth at Listonic. I enjoy diving deep into technical constraints to find creative ways to deliver value. Whether it’s refining a mobile user journey or optimizing an ad-delivery flow, my goal is always the same: clarity, impact, and scalability.

My core competencies and skills:
  • Product Strategy & Discovery
  • Business Stakeholder Management
  • Agile & Technical PRDs
  • Growth & Retention Strategy
  • Cross-functional Leadership
  • Data Analytics & Visualization
  • A/B Testing
  • Automation
  • AI Prototyping
  • AdTech & Monetization

Experience

Product Manager - Listonic (Product Team)
Jan 2024 - present

Leading the product evolution of the world’s most popular smart shopping list. I balance user-centric feature development for millions of users with high-scale monetization strategies, bridging the gap between engineering, design, and business goals.

I lead multidisciplinary teams across iOS, Android, Backend, Design and QA, ensuring seamless collaboration between internal departments and external business partners.

I also manage the AdCompanion SDK - a technical advertising product integrated by internal apps and external publishers. This involves overseeing the full SDK lifecycle, from technical documentation and integration support to advertising yield optimization.

My focus lies in R&D and rapid prototyping - leveraging AI and data analytics to validate new opportunities and drive innovation.

By translating complex needs from stakeholders like Top Management and Sales into clear, technical roadmaps, I ensure our development efforts are always aligned with market trends and measurable business impact.

I focused on technical ad-server management and yield optimization, while also overseeing UA strategies across Google Ads, Apple Search Ads, and Facebook Ads to drive high-ROI growth.

On the analytics front, I built advanced business Intelligence solutions in Looker Studio and utilized Python and SQL for deep-dive analysis and data processing.

I also played a key role in the early development and testing of our internal Ad SDK, ensuring seamless integration and high-quality ad delivery across multiple mobile platforms.
