I am Sotiris Bekiaris, a backend-focused software engineer from Thessaloniki, Greece. Over the past five years I have designed and delivered TypeScript/Node.js backends powering retail, cloud management, and mobile ecosystems, and I built a cloud gaming platform that secured €100k in EU funding. I thrive on end-to-end product development, from architecture and design to implementation, testing, deployment, and production support. Today I lead multiple ventures as founder and developer, building cross-platform solutions that bring communities together and empower small businesses. I’m comfortable with fast-moving environments, cloud-native stacks, and data-driven decision-making, and I enjoy mentoring teams to ship robust, scalable software.
