I consider myself a full stack developer. My focus the last 10 years was on Adobe Experience Manager and Java in general on the back-end side (~80%) and jQuery on the front-end (~20%). This focus switched a bit during the last 1-2 years, the back-end technology is still java though beside AEM also Spring Boot, but on the front-end side I focused on TypeScript and Vue2 (now also Vue3). The ratio also switched to ~30% back-end vs ~70% front-end.
