Vlad Stan is a CTO and hands-on software engineer with 11 years of experience building backend systems, developer tools and Bitcoin/Lightning integrations from Cluj-Napoca, Romania. He currently leads LNbits’ technical efforts to bring Lightning Network payments to the web and has deep, practical experience across Java, NodeJS and modern front-end stacks. Vlad is an active open-source contributor—work on projects like bitcoinjs-lib and the Lightning Browser Extension shows he bridges cryptography/security concerns with user-facing UI/UX improvements. His background in BPM engines (Activiti, Flowable) and enterprise integration (webMethods) gives him a rare combination of workflow, database optimization and low-level protocol expertise. Colleagues describe him playfully as a “pleb” on GitHub, but his commits reveal rigorous attention to tests, refactors and naming conventions that improve long-term maintainability. He blends pragmatic leadership with deep technical craft, especially around Bitcoin tooling and performant backend design.
