I build AI agents and GenAI systems that work in production.
Freelance AI engineer in Gothenburg, Sweden. I help startups and scaleups go from idea to deployed AI, with a focus on agentic architectures, LLM integrations, and production-grade infrastructure.
What I Build
AI Agents & GenAI Systems
I design and build agentic AI systems, from single-purpose LLM integrations to multi-step autonomous pipelines. This includes RAG systems, tool-using agents, structured output pipelines, and custom integrations with APIs and business systems. I work across the full stack: prompt engineering, evaluation frameworks, guardrails, and deployment.
Production ML & MLOps
Not everything is an LLM. When the problem calls for custom models (computer vision, forecasting, classification) I build and deploy them with proper MLOps: automated training, model serving, monitoring, and CI/CD. A decade of experience shipping ML systems means fewer surprises in production.
AI Strategy & Technical Advisory
I help CTOs and product teams figure out where AI actually fits, and where it doesn't. Build-vs-buy analysis, vendor evaluation, roadmap planning, and technical due diligence. Grounded in hands-on engineering, not slide decks.
Selected Work
Recent projects across fintech, trading, and automotive.
AI Transaction Categorization
Built an AI-powered bookkeeping integration that automatically categorizes financial transactions using Claude's structured output API. Designed for the Fortnox ecosystem (600K+ potential users). Includes a production MCP server wrapping the Fortnox API for seamless agent interaction.
Real-Time Trading Signals
Developed an algorithmic trading system for Swedish equities that processes real-time financial news via websocket, classifies signals using LLMs, and executes trades with a two-phase exit strategy. Includes a nightly LLM-based performance audit loop.
Computer Vision — Gaze & Eye Tracking
Spent years building production computer vision systems for automotive gaze and eye tracking at a publicly traded company. Deep experience with annotation pipelines, model training at scale, and deploying ML in safety-critical environments.
How I Work
Discovery
We talk about your problem, data, and goals. I'll tell you honestly if AI is the right tool.
Proposal
A clear scope with timeline and cost. No ambiguity.
Build
Iterative development. You see working demos early, not a big reveal at the end.
Ship & Support
Production deployment, documentation, handoff. I stay on until it runs smoothly.
