Ordered - an Allegro-inspired marketplace backend in Java 21 and Spring Boot. Extracted from a monolith with the Strangler Fig pattern into order, product, user and engagement services behind a gateway (Eureka, Config Server, JWT). Kafka with a transactional outbox, Resilience4j, Prometheus / Grafana / Jaeger, deployed with Docker Compose and Caddy on an Oracle Cloud VM. Start with ordered-infra or ordered-order-service.
Unordered - an AI gift-recommendation app in Flutter (Firebase, Cloudflare Workers, offline-first sync). Live demo.
Thesis and AI - my master's thesis compares how long vulnerabilities survive before being patched in AI-generated vs human-written code. I'm also building a small RAG project in Python (ChromaDB, sentence-transformers, Groq).
