My role spanned across 9 countries within the CEE region and involved collaboration between development centers representing 3 different nationalities.Key responsibilities:- Defined and implemented the technology strategy and roadmap for the team to align with business objectives.- Owned the frontend platform, including a UI library, A/B testing engine, and a server-side includes (SSI) proxy, a critical component for the entire company. Supported other teams in adopting and integrating the platform while continuously evolving it based on business needs.- Co-created company-wide technology strategies, standards, and initiatives to drive consistency and innovation.- Ensured cross-regional alignment on technological priorities, tools, and best practices.- In addition to these responsibilities, I was actively involved in daily coding and delivering business objectives at the team level.Key milestones:- Designed and implemented a gradual migration strategy for the Bulgarian site pazaruvaj.com, enabling a smooth transition from the legacy system to the new platform. This approach allowed us to progressively roll out changes from 0% to 100% of users while continuously evaluating the impact and ensuring stability. The solution was designed to be scalable and can be applied to six additional countries still running on legacy platforms, providing a clear path for future migrations across the CEE region.- Optimized cloud data transfer costs, identifying inefficiencies and implementing a cost-effective solution that reduced expenses by thousands of euros per month during the migration process.
