Renat Mitriuc

I’m a senior AI and full-stack developer with 7+ years of experience designing and building scalable web and mobile applications and AI-powered systems. I focus on turning advanced LLM capabilities into production-ready features—through LLM integration, RAG architecture, AI agents, and automatic workflow automation. I also bring strong backend and cloud engineering through microservices and reliable deployments.

In my recent work, I built an AI automation workflow platform with real-time voice and text agents, architecting multi-channel conversational agents across messaging and voice channels. I built frontends using React/Next.js/Vue for orchestration, dashboards, and monitoring, while implementing backend services with FastAPI and Node.js, scalable API layers, and robust external integrations. I also engineered real-time voice pipelines (STT/TTS/VAD), telephony-driven automation, and secure queue/background job systems.

Earlier, I led full-stack development of a scalable e-commerce marketplace platform with multi-vendor architecture, high-volume transactions, and automation-ready backend services. I also worked on legal-tech automation systems, delivering enterprise-grade frontends with Angular/RxJS and backend services with Django and PostgreSQL. There, I integrated AI for document summarization, extraction, compliance validation, and drafting assistance, while optimizing performance and implementing secure authentication/authorization and third-party workflow synchronization.

I’m passionate about combining cutting-edge AI with robust backend engineering to deliver intelligent systems that are maintainable, measurable, and fault-tolerant. I thrive where prompt engineering, retrieval, agent workflows, and DevOps practices (Docker, CI/CD, testing, and observability) all come together to ship real business outcomes.
