Test AI Engineer & Applied AI Specialist

Trustworthy AI is engineered, not assumed.

Poligoresa Ltd helps organisations build, validate and run trustworthy AI. We go beyond traditional QA — validating not only what your models produce, but how those outputs are produced.

Services

Four pillars of AI trust engineering

We bring AI quality strategy and automation leadership across the full delivery lifecycle — from the model itself to the data that feeds it, the governance around it, and its behaviour in production.

model/

Model validation

Evidence that your models perform — and keep performing — under real conditions.

  • Accuracy, precision and confidence scoring
  • Hallucination detection
  • Edge cases and adversarial inputs
data/

Data pipeline validation

Trust starts upstream. We validate the data your AI depends on, end to end.

  • Data validity and schema validation
  • Lineage, corrupted and missing data
  • Feature drift and data consistency
governance/

Fairness & governance

AI you can explain, reproduce and defend — including in regulated GxP environments.

  • Bias testing and explainability
  • Reproducibility, traceability and auditability
  • Compliance for regulated GxP environments
production/

Production trust engineering

Trust doesn't stop at release. We keep AI observable, monitored and recoverable.

  • Drift monitoring, observability and telemetry
  • Anomaly detection
  • Rollback strategy and canary releases

Backed by scalable test automation

UI & API automation, continuous validation in CI/CD, plus test strategy, QA leadership and release governance.

How we work

Trust, engineered into every stage

A clear, repeatable path from AI quality strategy to continuously validated systems in production.

STEP 01

Assess

We map your AI systems, data pipelines and release process, and define a quality strategy with measurable trust criteria.

STEP 02

Engineer

We build scalable automation frameworks — new or improved on your existing systems — across UI, API, model and data layers.

STEP 03

Validate

Continuous validation runs in your CI/CD pipelines, so every change is checked for accuracy, fairness and data integrity before release.

STEP 04

Operate

In production, drift monitoring, telemetry and anomaly detection keep trust measurable — with rollback and canary strategies ready.

What clients get

Measurable quality. Production-ready trust.

Every engagement is designed to leave your teams faster, your releases safer and your AI demonstrably trustworthy.

frameworks

Scalable automation frameworks

Built new or improved for existing systems — designed to grow with your platform.

velocity

Lower manual effort, faster feedback

Automation replaces repetitive checks, shortening the loop from change to confidence.

confidence

Higher release confidence

Every release backed by continuous validation across model, data and application layers.

metrics

Measurable quality metrics

Trust expressed in numbers — accuracy, drift, coverage and audit-ready evidence.

production

Production-ready, trustworthy AI

Systems validated not just for what they output, but how those outputs are produced.

leadership

Cross-functional leadership

QA leadership and influence across engineering, data and delivery teams.

About

A specialist consultancy for the AI era of quality

Poligoresa Ltd is a specialist Test AI Engineer and Applied AI Specialist consultancy, helping organisations build, validate and run trustworthy AI across SaaS, FinTech, BioPharma and data-driven platforms.

Traditional QA asks whether software behaves as specified. AI systems demand more: their behaviour emerges from data, models and pipelines that change over time. Our focus is engineering trust into those systems — validating not only the outputs, but how those outputs are produced.

We combine deep test automation engineering with applied AI expertise, bringing quality strategy, automation leadership and release governance across the full delivery lifecycle.

Haja

Founder · Test AI Engineer & Applied AI Specialist

A short conversation is usually enough to see where trust breaks down in an AI system — and what it would take to engineer it back in.

I've spent my career at the intersection of test automation and applied AI: building validation frameworks, leading QA strategy across delivery teams, and making AI systems safe to release in regulated environments. If your models, pipelines or releases keep you up at night, tell me what's happening — a few lines is enough to start.
