Emir C.

Senior full-stack engineer and solution architect with 20+ years of experience. I build production-grade SaaS products end to end, solo: architecture, backend, web and mobile, DevOps, and AI. I run my own multi-tenant SaaS products (POS, tourism, project management, hotel automation), so I know what it takes to ship software that survives real users, not just demos. What I deliver Backend and APIs: NestJS, Node.js, TypeScript, PostgreSQL, Redis/BullMQ, REST, real-time (WebSocket/SSE) Web and mobile: React, Next.js, Ionic/Capacitor AI and automation: LLM-powered assistants and agents, RAG with pgvector, n8n workflows, ComfyUI pipelines Cloud and DevOps: Docker, Kubernetes, GitLab CI/CD, AWS, GCP, Azure, Cloudflare Beyond web: Java/Spring, C/C++, Linux System/Kernel Programming, Embedded/IoT, Streaming (FFmpeg, Nginx-RTMP, Wowza) How I work Clean, maintainable code. No over-engineering. Fast delivery. I use AI tooling to do the work of a small team. Clear communication and honest estimates. Full ownership, from architecture to deployment. Good fit if you need An MVP built quickly by one senior person A SaaS platform with multi-tenant architecture, payments, and integrations An AI assistant or automation layer added to an existing product A technical lead for a complex or legacy system Send me a message with what you’re building and I’ll tell you honestly how I’d approach it. . .
