I have led payment, subscription, monetization, and marketplace products from strategy and discovery through delivery and optimization. My work includes driving 150% revenue growth through payment product strategy and launching a subscription service that established a new recurring revenue stream within three months.

I use customer insights, market research, analytics, conversion metrics, transaction volume, and fraud data to prioritize opportunities and improve product performance.

I am comfortable operating in regulated environments and have hands-on experience with PSD2, PCI-DSS, and GDPR requirements. I focus on delivering secure, intuitive experiences while balancing usability, compliance, technical feasibility, and business growth.

I own the product strategy and roadmap for payment solutions, identifying and prioritizing opportunities through market research, competitive analysis, and customer insights. My work contributed to 150% revenue growth by improving the payment product strategy and platform capabilities.

I lead and mentor a cross-functional team, coordinating engineering, compliance, sales, and operations.

Product & Delivery Manager Skroutz, Ecommerce Services

I led strategic company-level initiatives using the OKRs framework and translated commercial, technical, and legal requirements into actionable product delivery plans. I managed planning, delivery, release management, risks, and dependencies across multiple agile teams.

I improved agile delivery processes to increase efficiency and transparency. I also launched a new end-user subscription service in under three months, creating a recurring revenue model for the business.

Product Owner – HealthTech Doctoranytime

I owned the roadmap for the company SaaS platform and B2B initiatives, leading the development of a digital product connecting medical professionals and patients. The platform supported online transactions and new feature delivery from concept through launch.

I gathered and prioritized stakeholder requirements, established agile processes and feedback loops, and built internal practices for roadmap tracking, stakeholder reporting, and delivery management. These improvements strengthened collaboration, adoption, and delivery quality.

Product Owner – Mobile Marketing Upstream

I delivered initiatives for core subscription and monetization platforms, including real-time purchasing products for digital services and data bundles. One product generated approximately 30% of revenue for a major account after launch.

I led agile ceremonies and coordinated cross-functional, multi-product teams across web, mobile, and platform areas. I also contributed to team structure, delivery processes, execution rhythms, and end-to-end user journey improvements.

I directly managed a team of nine people responsible for requirements analysis and solution design. I acted as the primary interface between commercial, product, and operations teams to align priorities and delivery expectations.
