AI & Automation for Legal Professionals

I design and build practical AI systems, document automation and legal-tech infrastructure for lawyers, legal teams and document-heavy organisations.

From private RAG assistants and AI agents to Microsoft Word automation, document assembly, workflow integrations and bespoke web applications.

WHAT I BUILD

Technology that removes repetitive work.

Practical systems designed around real workflows rather than AI demonstrations that never reach production.

01

AI Integration

Add reliable AI capabilities to existing applications, workflows and internal systems.

  • LLM and API integration
  • Structured extraction
  • Document classification
  • Summarisation and drafting workflows
  • Human-in-the-loop review
02

RAG & Knowledge Systems

Search and reason across your own documents using retrieval-augmented generation.

  • Private knowledge assistants
  • Semantic and hybrid search
  • Vector databases
  • Document ingestion pipelines
  • Source citations and traceability
  • Permission-aware retrieval
03

AI Agents

Agentic workflows capable of performing structured, multi-stage tasks while keeping humans in control.

  • Research agents
  • Document-processing agents
  • Tool and API use
  • Multi-step workflows
  • Validation and guardrails
05

Legal Workflow Automation

Connect fragmented processes into simpler end-to-end workflows.

  • Client onboarding
  • Conflict checks
  • Matter intake
  • RCS / RBE research workflows
  • Data extraction
  • Internal workflow tooling
06

Custom Applications

Purpose-built tools where off-the-shelf legal software does not fit the workflow.

  • Internal web applications
  • Client self-service portals
  • APIs and integrations
  • Databases and dashboards
  • Legal data analysis

LEGAL + TECHNICAL CONTEXT

Legal workflows are not generic business workflows.

Legal automation works best when the person designing the technology understands documents, evidence, confidentiality, review processes and the consequences of incorrect output.

My work sits between software engineering, artificial intelligence and legal workflow design, with particular attention to explainability, source traceability, permissions and human review.

APPROACH

AI that survives contact with real work.

Useful before impressive

Automation should save measurable time or improve quality—not merely demonstrate that an LLM can produce text.

Sources over hallucinations

Where factual reliability matters, systems should retrieve authoritative material and expose their sources.

Human review by design

High-impact workflows should make review and validation easy rather than pretending human judgement is obsolete.

Privacy matters

Architecture should reflect confidentiality, permissions and the sensitivity of the information being processed.

ABOUT

Gilles Siegfrid Weber

I build AI, automation and software solutions with a particular focus on legal and document-intensive workflows.

My background combines legal knowledge with hands-on software development, allowing me to translate between legal requirements and technical implementation.

Based in Luxembourg.
