[For Hire] Senior AI & Full-Stack Engineer | LLM Apps, RAG, Agents, Evals & AI Infrastructure
I am a Senior AI Engineer based in EU (Romania), available for freelance projects, B2B contracts, part-time work, or full-time remote roles.
I build complete AI systems, not only demos or prompt wrappers. This includes the LLM layer, retrieval, agents, evaluations, observability, backend APIs, infrastructure, and user-facing applications.
What I Build
- RAG systems over documents, PDFs, websites, and internal company data
- AI agents with tools, structured outputs, retries, memory, and traceability
- LLM applications for support, search, extraction, classification, and automation
- Evaluation systems with golden datasets, LLM-as-judge scoring, and benchmark dashboards
- Document processing and structured data extraction pipelines
- Voice AI systems using speech-to-text, text-to-speech, and LLMs
- Full-stack AI products from architecture to deployment
- Internal AI platforms, APIs, dashboards, and developer tools
Tech Stack
- AI & LLMs: OpenAI, Azure OpenAI, Gemini, RAG, AI agents, embeddings, vector search, LLM evaluations, Langfuse, RAGAS, FAISS, Qdrant, pgvector
- Backend: Python, FastAPI, Pydantic, async APIs, WebSockets, PostgreSQL, Supabase, Redis
- Frontend: React, Next.js, TypeScript, Tailwind, Shadcn/UI
- Cloud & Infrastructure: Azure, AWS, Docker, Kubernetes, Helm, Linux, CI/CD, OpenTelemetry
How I Work
I start with the business problem and define a clear first milestone. I then handle the architecture, development, AI integration, testing, evaluation, and deployment.
I care about measurable quality, traces, failure cases, latency, and costs. The goal is software that works with real users and real data.
Compensation & Engagement
I can work hourly or on a fixed project scope through my Romanian company.
