I'm Erik Kubica, a Senior Full-Stack Developer and AI Engineer, open to new opportunities. I bring 11+ years of production experience and have shipped 140+ projects across SaaS, e-commerce, media, and government sectors. My backend expertise is PHP/Symfony with strong React/Next.js frontend work, and I’m now diving deeper into AI engineering, building MCP servers, agent workflows, and multi-model integrations for real production use cases. I’m EU-registered for B2B freelancing and comfortable across SEA and EU time zones. I value robust architectures, scalable data-driven apps, and collaborative teams. If you want a reliable, hands-on developer who can bridge frontend and backend with AI-driven features, I’m your person.…I'm Erik Kubica, a Senior Full-Stack Developer and AI Engineer, open to new opportunities.
