Rockstar🎓
Top SchoolOleg Abrazhaev is a Berlin-based Staff Software Engineer with 13 years of hands-on experience building full-stack and distributed systems across Scala, Java, TypeScript, PHP and Python. He drives architecture and delivery for notification and AI platforms—recently implementing a replacement notifications platform at Kpler and designing AI chatbots and analytics dashboards as an interim CTO—while remaining deeply involved in code. Oleg combines backend expertise (Kafka, PostgreSQL, RabbitMQ, Spring Boot) with modern frontend work (Vue 3, TypeScript, composition API) and practical DevOps (Kubernetes, AWS, Helm, ArgoCD). A long-time open-source contributor, he has improved phpMyAdmin’s UI by extracting Twig templates and fixed numerous PHP/RabbitMQ tutorial issues, demonstrating an eye for maintainability and cross-platform test robustness. He’s equally comfortable leading teams and doing 50–70% hands‑on coding, having scaled engineering orgs, cut database footprints dramatically, and mentored engineers across time zones. Colleagues know him for pragmatic architecture choices, relentless refactors, and an appetite for experimenting with LLM fine-tuning and prompt engineering.
