Malek Maghraoui, AI engineer

AI you can trust in production.

I'm Malek, an AI engineer. I build LLM agents, evals and guardrails end to end, from the Postgres schema to the prompt, so AI features hold up when real users arrive.

Most AI demos work. A lot of AI in production quietly makes things up. I build the other kind: agents that ask before they act, answers checked against ground truth, and pipelines that refuse to invent facts.

How I build.

Four rules I don't break, each with the projects that taught it. The panels are live: run them, approve or reject, replay.

Telemetry1 of 4

Evals before vibes.

If I can't measure it, I don't ship it. The eval comes before the feature: labelled cases, a score, and a gate that blocks a release when an answer drifts from the truth.

  • KorbyxAn evaluation harness checks the AI assistant's answers against the analytics engine's ground truth in CI, with prompt-injection tests alongside.
  • BridgeLabelled audio fixtures score how much speech survives and how much music leaks, against a frozen copy of the previous router.

Go / no-go2 of 4

Agents with brakes.

An agent can read freely. Before it writes anything, a person approves. Every argument it produces is checked against a schema before it gets that far.

  • QTrust43 tools. The 24 that write become pending actions, and nothing touches the database until an admin approves.
  • FalahiVoice-note extractions under 0.75 confidence go to a person, and the farmer gets a clarifying question instead of a wrong listing.

agent · read tool, runs directly

get_family("Ben Salem") → 3 children enrolled, 120 TND each

agent · write tool, needs approval

create_invoice({
  family: "Ben Salem",
  amount: 360,
  currency: "TND",

})

Abort criteria3 of 4

Facts, not fiction.

Generated text has to trace back to a source. A number the source never said gets removed, however plausible it sounds.

  • Edah StudioA 5-layer gate deletes unsourced numbers and re-anchors every scene to its paragraph. A small model that invented whole scenes ended with zero flagged.
  • TuniTaxAIAnswers stay tied to the tax law they come from, across more than 5,000 documents.

Pressure test4 of 4

Test the hull.

Access rules are code, so they get tests. I don't trust row-level security until a script has tried to break it.

  • Bridge19 end-to-end checks create throwaway users, try to cross every boundary, then clean up after themselves.
  • QTrustAbout 70 unscoped queries were found and fixed before a single AI feature shipped.

Why malekverse.

Two reasons. I love astronomy and space. And everything I build belongs to one universe: different missions, the same standards.

So the site runs on a little real astronomy. The panel here is computed in your browser, right now, for the sky over Tunisia. No API, no image: just orbital mechanics and dots.
