04About

Engineer by training. Analyst by craft.

I started as a civil engineer and ended up modelling something different, the data behind how global enterprises actually run. Four years at Ernst & Young GDS took me from audit analytics in the Nordics to construction KPIs for NEOM in Dubai, ESG reporting for US & UK leadership, and aviation analytics for Switzerland and France.

What I optimise for: dashboards executives actually open the next morning. That usually means fewer charts, a cleaner star schema, faster DAX, and a Figma pass before a single visual is built.

Outside work I'm building MaidGo, an AI-assisted pan-India home services app with multilingual support for low-literacy service providers, to keep my product instincts sharp.
