Top SchoolOlha Lashkul is a Senior Frontend Developer with 8 years of experience building React and TypeScript applications across e-commerce, finance, and cybersecurity, currently shaping product and delivery at Nord Security in Berlin.

At BigCommerce she expanded checkout capabilities by integrating PayPal payment flows into well-known open-source SDKs, demonstrating both API integration and thorough test coverage.
