I'm building and supporting a high-volume trade certification and processing platform at Luxoft for one of Europe’s largest investment banks, handling millions of trades daily. I contribute to cloud migration to Azure AKS and Docker, TIBCO EMS upgrades, database stability, and resilient production operations.

Previously at Cognity, I led teams delivering Oracle Commerce solutions for Orange Romania, T-Mobile Romania, and PureFormulas USA. I built integrations with PayU, PayPal, Stripe, Yotpo, Sift, Okta, and client REST/SOAP systems, while owning checkout, customer, catalog, search, and promotion capabilities.

Across 14 years in enterprise software, including 1Datagroup and EPAM Systems, I've delivered end-to-end e-commerce projects, modernized Oracle Commerce platforms, automated deployments, resolved critical incidents, and mentored engineers.
