Lead Software Engineer and Team Lead at MediaMarkt, delivering a payments and identity platform across four European markets.

Spain

Message

At MediaMarkt, I lead delivery of a unified ecommerce payments and customer identity platform across four European markets. I managed a team of six engineers and implemented OAuth 2.0, OIDC, SAML federation, MFA, and JWT-based authorization.

I also embedded Generative AI tooling into engineering workflows, including LangChain-based developer Q&A and automated test generation. The work reduced defect escape rate by about 30% and manual review overhead by 40%.

At Deutsche Bank, I worked on cloud-native ecommerce, real-time financial data streaming, compliance reporting, and a GCP mainframe migration. The compliance system cut reporting cycles from three days to four hours, and the migration involved coordinating delivery across three squads.

Earlier, I held technical lead and software engineering roles at Nagarro, Nucleus Software, and Tech Mahindra. My work included serverless payment and analytics platforms, AWS containerization and cloud migration, and automated testing for Java applications.
