Senior🎓
Top SchoolJoni Aaltonen is a pragmatic CTO and full‑stack developer with 11+ years of experience building scalable web, mobile and desktop applications from UI/UX design to autoscaling cloud infrastructure. Based in Helsinki, he leads development of speech-recognition enterprise solutions for healthcare while also founding and running his own web agency, blending product ownership with hands-on coding. His technical breadth spans Java (Spring/Hibernate), modern JavaScript frameworks (React, Redux, Angular), Rust/WASM, RESTful APIs, databases and a deep AWS/Kubernetes toolkit augmented by an AWS SysOps certification. Comfortable in virtual teams, he pairs a good visual eye and UX sensibility with practical integration experience (EHRs, RabbitMQ, Keycloak) and long-running delivery across public procurements. Notably, he progresses between strategic leadership and core engineering work—still shipping code while managing growth and user training.
