Dávid Szemán Quality leadership, applied to AI adoption

AI adoption · evaluation · strategy

I build AI systems, then prove they work.

Extraction pipelines, adoption decision tooling, production reporting, generated content with automated screening. Two were built inside paid client engagements — a reporting pipeline used from 2025 to March 2026, and a certification framework handed over when I left. The rest I built and evaluated myself, and each entry says which it is. Twelve years of quality leadership behind it, which is why the interesting part is usually the evidence, not the demo.

12+ years
in quality and delivery leadership, from sole in-house QA to QA Manager
70+ testers
coordinated through team leads in the largest organisation; 45–50 with direct hiring and performance authority
4 platform families
release-quality scope across mobile, web, TV and console, including payments and certification
Since 2025
building and evaluating AI systems hands-on, two of them inside paid client engagements — with seven case studies that set out what failed on first contact and the numbers behind the fix

2026

Vision-to-catalogue extraction pipeline

Photograph a physical item, get back the verified catalogue record.

One case left deliberately failing: the record does not exist in the source catalogue

  • n8n
  • Vision LLM
  • Cloudflare D1
2026

AI use-case decision-support platform

Decision-support software for choosing which AI use cases an organisation should fund and ship.

Around ten design decisions documented with the alternative rejected

  • React
  • TypeScript
  • Zustand
2026

Offline certification framework with LLM-generated content

Desktop exam software, plus 650 bilingual assessment items generated and validated by language models.

Handed over when I left, at my manager's request. I have no data on how many people sat it afterwards, and I am not going to estimate — what I can claim is the build and the generation system, not the adoption

  • Electron
  • Node.js
  • Python
2025–2026

Daily LLM reporting pipeline, in production

Test metrics, stakeholder summaries and risk reports generated every morning from live delivery data.

Built inside a confidential client engagement — client and product are not named

  • LLM API
  • Delivery tooling integrations
2026

A personal AI operating system

The infrastructure I run my own work on: memory, tickets, sync, budget rules, generated views.

Enforced cost discipline: exploratory fan-out requires stated scale and approval

  • Node.js (zero-dependency)
  • Git
  • Claude Code skills
2026

Image classification for a small retail business

A phone-first tool that sorts incoming second-hand stock into categories from photographs.

Awaiting the customer decision. Dedicated API billing, authentication and accuracy tuning are scoped but not built

  • Next.js
  • Vercel
  • Vision model

The reasoning behind it

Five questions, in this order

The method →

Starting at question three is how AI spend gets wasted. Stage four is the one that most often has no owner — and it is where I come from.

  1. 1 Find the bottleneck Business diagnosis
  2. 2 Choose the instrument Judgement
  3. 3 Redesign the process Process thinking
  4. 4 Prove it works Engineering rigour — the release gate between pilot and production
  5. 5 Make it stick Enterprise scaling

Where I am useful

Deciding which AI use cases are worth funding. Setting the acceptance bar before a pilot starts. Getting something out of pilot purgatory — or killing it honestly.
