Context

Freelance engagement at Wanted Design, a digital agency (e-marketing and AI/automation). Acting as technical and strategic AI/automation expert, contributing to alignment between offerings and technical reality.

From January to June 2026. Started as a consultant (AI offerings and conference support), then moved to AI & Automation Tech Lead.

My role: technical lead across all AI and automation topics, from architecture to pre-sales scoping, including team mentoring and infrastructure maintenance.

Key achievements

AI agent platform

Design of a proprietary AI agent platform, reusable across missions, as an alternative to market SaaS solutions. Shared technical foundation with specialised agents, per-mission data isolation, anti-hallucination guardrails and GDPR / AI Act compliance by design.

Scope: architecture, ADRs and technical documentation, with implementation handed over to a dedicated team.

Shaping AI and automation offerings

Structuring service offerings so they could be sold by non-technical salespeople, together with the matching sales collateral. Industrialised the production of that collateral through agent-based tooling.

Public AI outreach: conference support on ethics in AI, BNI talk (30 min + Q&A).

Pre-sales technical scoping

Feasibility studies and architecture design on client projects: data source selection, modelling, public API integration, ADRs, effort estimates and support during client meetings.

Technical mentoring

Supporting the technical team on AI/automation projects: passing on architecture best practices, validating technical choices, pre-production reviews.

Infrastructure & Ops

Responsible for the setup and maintenance of the production technical infrastructure (orchestration, automated workflows, monitoring).

Takeaways

  • AI and automation architecture in a production context
  • Designing technical offerings and sales enablement
  • Multi-agent platform architecture, guardrails and GDPR / AI Act compliance
  • Developer mentoring and technical knowledge transfer
  • Public speaking and technical outreach (BNI, conferences)
  • Business perspective: translating technology into an accessible sales narrative
