About

Senior Frontend Engineer with 8+ years building high-load fintech and enterprise systems. I work at the architecture level — designing systems that scale, not just shipping features. What I bring: → Microfrontend architecture for distributed banking platforms (50,000+ concurrent users) → Full ownership: API contracts, OIDC auth, CI/CD, Kubernetes deployments → Measurable impact: 70–80% rendering performance improvement, 40–60% reduction in manual regression effort → Backend contribution: Java · Spring Boot · PostgreSQL · Kafka · Redis Core stack: React · TypeScript · Next.js · MobX · Redux · Webpack · Playwright · Storybook · Kubernetes I've delivered mission-critical platforms in fintech (banking microservices) and national energy infrastructure — environments where reliability, security, and scale are non-negotiable. AI-augmented development: → Cursor for AI-assisted coding and refactoring → Local LLM setup (LM Studio + Qwen 30B) for privacy-sensitive codebases → Ollama deployed in Docker for team-accessible local inference → Practical AI integration in production products 📍 Based in Nicosia, Cyprus (EU) — actively looking for Senior Frontend / Full-Stack roles in Germany (Berlin · Munich · Hamburg) or remote with EU companies. Open to relocation. EU Blue Card candidate.
