Senior🎓
Top SchoolSergey Romanenko is a digital-nomad software engineer and instructor with 13 years of experience building full-stack web applications, frontend frameworks, and scalable architectures for large teams and open-source projects. He teaches and mentors remotely—authoring 10+ popular Stepik courses that reached 10K+ students and earned 900+ certificates and a 2023 “Breakthrough of the Year” award—while also guiding junior engineers at Solvery.io. Sergey combines hands-on engineering (PHP, JS, REST APIs, SQL, modern frontend toolchains) with automation of build/test workflows and interface standardization to boost team productivity. As an active open-source contributor and maintainer, he created and maintained projects like Flextype and contributed to CMS and tooling ecosystems, and earlier implemented the Monstra CMS installer. Based in Da Nang, Vietnam, he pairs deep practical experience with an educator’s knack for turning complex topics into interactive, simulator-driven learning. He’s equally comfortable shaping architecture and shipping the small utilities that make large projects run smoother.
