What I'm looking for

My background fits teams that need steady engineering work, clear problem solving, and careful handling of releases and third-party dependencies.

At Cremarc, I built C# services for campaign tracking and lead capture, connecting web forms, ad sources, and CRM records. I also implemented reporting and audience-sync APIs that reduced duplicate contact updates by 28%.

Previously, I developed climate data services at Cervest, card and payment support flows at Revolut, and grocery operations software at Ocado Retail. Across these products, I worked on data processing, integrations, and production fixes that supported customer-facing workflows and internal operations.
