Kari Heikkinen is a Senior Developer in Helsinki with 11 years of experience building responsive frontends and cloud-native, serverless backends. He blends hands-on frontend work with UX collaboration, preferring to influence design rather than just implement it, which improves developer-designer outcomes. His background spans embedded systems and Linux driver work to full-stack and API/system design, giving him a rare end-to-end perspective on performance and integration. At Nordcloud/SC5 he moved from lead frontend/architect roles into full-stack cloud-native engineering, and now drives solutions at Rescomms. Comfortable with modern toolchains, Kari brings both pragmatic engineering and system-architecture thinking to scalable digital services. He often pairs interface-focused work with backend scalability considerations, ensuring smooth user experiences under real-world loads.
