Served as the Technical Lead for the marketing board, orchestrating the full development lifecycle for a diverse portfolio of brand-specific websites and mobile applications. I spearheaded the adoption of CoronaLabs (Lua) for cross-platform mobile development, allowing for high-performance deployment across multiple OS environments.

Energy usage of websites and web based applications has a huge impact on CO2 emissions and consequently on climate change. Web sites consume energy for its creation and keep consuming energy when they are viewed by visitors all around the world. CO2 Web Watch monitors, reports and offset CO2 emissions of energy consumption of websites and web based applications at creation and thereof. CO2 Web Watch uses a consistent and transparent approach for accounting for these emissions applying the “GHG Protocol Product Life Cycle Accounting and Reporting Standard ICT Sector Guidance” to assess the CO2 emissions of websites and web based applications.
