AI Engineering Consultant
Designing & Building AI Systems for Companies That Need a Real Competitive Advantage.
I'm Lucas Semelin, AI Engineering Consultant. I design and build AI applications and systems — from software architecture to agent behavior and user experience — so your business doesn't just adopt AI, it operates differently because of it.
Most companies know they need to move on AI. The problem is how.
They experiment with tools, bolt AI features onto existing software, or hand the project to a development team that knows how to code but not how to design intelligent systems. The result is AI that technically works but doesn't change how the business operates.
The real challenge isn't access to AI models. It's knowing how to architect the system around them, design how agents think and behave, and make sure the people using it actually trust it. That's exactly what I do.
AI Engineering
I design and build AI applications and systems for companies that need a real competitive advantage, whether you're starting from scratch or evolving what you already have.
What this covers:
- ✓Software and AI architecture
- ✓Context engineering: system prompts, memory, conversation history, guardrails and output design
- ✓Agents and workflows
- ✓RAG and knowledge pipelines
- ✓MCP and REST / GraphQL API integration
- ✓Backend and frontend development
- ✓UX for human-AI interaction
How we can work together:
Retainer
I work as your dedicated AI Engineering Consultant on an ongoing basis, without the overhead of a full-time hire. Best for companies building or evolving AI systems over time.
Project
A defined engagement with a specific scope and deliverables. Best for companies with a clear problem to solve.
I build what I design.
I don't just advise on AI systems, I architect and implement them. That means every design decision I make is grounded in what actually works in production, not what looks good in a presentation.
I cover all three layers.
Most people working on AI handle either the technical layer or the user experience layer. I work across all three: the software and AI architecture underneath, the agent behavior and intelligence on top, and the human experience around it. That's what makes the difference between AI that gets used and AI that gets abandoned.
20+ years building real software.
I've designed and built software for global companies and government organizations. That depth of experience means I know where systems break, how to design for scale, and how to make engineering decisions that don't quietly ruin the user experience.
Cases
More details on each project available on a call.
B2B Industrial Support Tickets
Designed a two-agent AI system for an industrial B2B support platform. Operators receive contextualized guidance, technicians receive diagnostics with explicit confidence levels. Result: 50% reduction in resolution time, tickets with 75 to 88% of context pre-filled.
Eunoia Care, Patient Care Assistant
Designed an AI system that automatically categorizes clinical information, learns from patient history, and allows human correction at any time. The system has explicit boundaries: it stores and retrieves patient data, never diagnoses, and communicates that clearly when someone tries to push beyond its scope. Result: complete patient records in minutes, any data retrievable in seconds.
Arketify, SaaS Platform
Designed how users and AI agents collaborate on a team analytics platform: what the AI generates autonomously, when it requires human input, and how trust is built into the recommendations. Result: 85% completion rate and onboarding in under 10 minutes.
