Berfu Ece Bayçelebi

I build, secure, and grow web products end-to-end. Currently leading cross-functional technical SEO and AI-powered automation initiatives at Çiçeksepeti, Turkey's leading e-commerce marketplace — combining hands-on development with data-driven growth strategy.

From spinning up secure server environments to building React interfaces, from BigQuery data pipelines to n8n automation workflows — I work across the entire stack. My background in Statistics and Finance sharpens my approach to data analysis and strategic decision-making.

I also contribute pro-bono technical work to civil society organizations — including technical SEO audits, website development, and infrastructure support for nonprofits across Turkey and internationally.
