What I'm looking for

Remote senior backend role where I can own architectural decisions end-to-end, work on technically complex problems, and contribute to a team that takes engineering quality seriously.

Backend engineer with 5+ years delivering production microservices and event-driven systems, now focused on AI-integrated backend architectures. Specialises in JVM-based systems (Java, Quarkus, Spring Boot) combined with ML pipelines, RAG architectures, and LLM integration via LangChain4j. Holds an MSc in Big Data Analytics with hands-on experience building predictive systems (XGBoost, RandomForest, BERT) deployed as production APIs. Brings rare cross-functional depth — architecture, ML integration, data engineering, and team leadership in the same role.
