Top School

Alexander Kachkaev is a senior software engineer and visual data scientist based in London with 13 years of experience building interactive data-heavy web applications and platforms. He combines a PhD in GIS and visual analytics with strong software architecture and devops chops, having led UI architecture and product-facing engineering at orgvue and contributed to open-source projects like Prettier and Next.js examples. His work spans spatial analysis, datavis design, human–machine interfaces and domain applications from urban planning to energy and transport, often turning complex datasets into actionable, story-driven tools. At HASH and BlockProtocol he focused on front-end systems and design systems for open standards, and his OSS contributions include improvements to Prettier’s plugin API and developer tooling. Colleagues describe him as a team player who elevates engineering culture through mentorship, shared tooling and guilds — a researcher who ships production-ready solutions. An unusual strength is his ability to bridge academic visual analytics research with pragmatic product engineering to democratize data-driven decision making.
