Hire a design engineer for AI products

I design and build production AI products end to end, from the interface to the system behind it. I work remotely from Tunisia (UTC+1) with teams in Europe, the UK, and the US, on contract or full-time.

What I build

AI agents and workflows
Tool-using agents and multi-step workflows that turn operational work into reliable, reviewable steps.
Retrieval and document intelligence
RAG over reports, contracts, and internal files, with semantic search and structured extraction.
Interfaces for AI products
Product and interaction design for AI features, built in Next.js, so the system is usable, not just capable.
Evaluation and observability
Evals, tracing, and monitoring that keep AI features dependable once real users arrive.

Questions

Are you available for new work?
Yes. I take contract work, either as a monthly partnership or a fixed project, and I’m open to full-time remote roles.
What time zone do you work in?
I’m based in Tunisia, on UTC+1 all year. That’s the same as Central European Time in winter and an hour behind it in summer, so I overlap fully with teams in Europe and the UK, and with the morning of US East Coast teams.
How do contracts and payments work?
Whichever suits your team: a direct B2B contract with monthly or milestone invoices, or through Deel, Contra, Malt, or Upwork.
How much do you charge?
Monthly partnerships start at $3,500 a month and projects at $5,000. Pricing scales with scope, complexity, and delivery cadence.
What do you work on?
Production AI products from first concept to deployed system: agents, document intelligence, retrieval, and the interfaces around them. I cover product design, engineering, and client delivery, so one person can take a feature from design to production.
What’s your stack?
Next.js, React, and TypeScript on the front end; Python, FastAPI, Django, NestJS, and ElysiaJS on the back end; LangChain, LangGraph, Qdrant, Milvus, and LiveKit for AI systems; PostgreSQL and Redis for data; Cloudflare, AWS, Azure, GCP, Docker, and Kubernetes for infrastructure.
Who have you worked with?
Remote teams in Germany, Switzerland, and the US: a pharma AI company (p.AI), a Swiss language AI company (Nexilan), and a generative AI SaaS (AxeGenAI). Case studies for Pecauva and Three Zero are on this site.
