I help teams make quality part of delivery from the start. My experience spans QA leadership, software engineering, business analysis, BI, DevOps and product delivery.

I work on API contracts, end-to-end testing, performance, security, accessibility and mobile testing. I have used Specmatic with C#, Python, JavaScript, TypeScript and Java. My other frameworks include Selenium with Java, Robot Framework with Python and Codeception with PHP. I also use Playwright and Appium, plus k6, JMeter, Datadog and BrowserStack. I have integrated automated tests into workflows with Azure Pipelines, GitHub Actions and GitLab CI.

My AI work includes orchestrating LLM and RAG workflows across local and cloud platforms, multi-agent patterns and MCP integrations for APIs and test frameworks. I bring practical awareness of AI governance, data protection and human oversight, informed by certifications in GDPR, the EU AI Act and DORA.

I also build data harnesses and coach cross-functional teams to improve quality ownership, feedback and delivery practices.

AI / Machine learning / Technology ecosystems

Technology stacks by ecosystem.

Experience spans leading AI platforms, with models, services and engineering patterns selected for each use case. The stack can include multiple large language models (LLMs), retrieval-augmented generation (RAG), machine learning and neural networks.

MICROSOFT

Microsoft ecosystem

AI & LLMs: Azure AI Foundry, Azure OpenAI Service and model selection across available GPT and other supported model families.

RAG & data: Azure AI Search, embeddings, vector and hybrid search, document retrieval and grounded generation.

Engineering & ML: Azure Machine Learning, Semantic Kernel, Python, PyTorch and TensorFlow for model development, orchestration and integration.

GOOGLE

Google ecosystem

AI & LLMs: Gemini models through Vertex AI and the Google AI ecosystem, choosing models to match capability, latency and cost needs.

RAG & data: Vertex AI Search, vector search, embeddings, grounding and retrieval pipelines over enterprise knowledge.

Engineering & ML: Vertex AI, Google Cloud, TensorFlow, JAX and Python for machine learning workflows, training, evaluation and deployment.

ANTHROPIC

Anthropic ecosystem

AI & LLMs: Claude models through the Anthropic API and supported cloud platforms, applied to reasoning, coding and enterprise workflows.

RAG & integration: Claude-powered retrieval workflows using embeddings, vector databases, contextual grounding, tool use and connected knowledge sources.

Engineering & ML: Model evaluation, prompt and context engineering, Python integrations and neural-network-based ML systems alongside LLM applications.

MISTRAL AI

Mistral ecosystem

AI & LLMs: Mistral model families through the Mistral API, with model choice based on reasoning quality, coding needs, throughput, latency and cost.

RAG & data: Mistral embeddings, document understanding and retrieval pipelines that connect enterprise knowledge to grounded LLM responses.

Engineering & deployment: Mistral Studio/API, agent and tool workflows, evaluation, and open-weight model options for cloud or self-hosted deployments where licensing and infrastructure fit.

Mistral documentation

EUROPEAN MODELS

European AI ecosystem

Explore European models such as Switzerland’s open Apertus, EuroLLM, Teuken, and Aleph Alpha’s Pharia family. Compare language coverage, access, deployment options, and governance to identify the best fit.

CHINESE MODELS

Chinese AI ecosystem

Evaluate models such as Qwen, DeepSeek, GLM, Kimi, and MiniMax through provider APIs and cloud platforms. Support covers model selection, retrieval-augmented generation (RAG), tool use, and evaluation for multilingual and regional requirements.

Architecture / Ownership / Autonomy

Build AI with clear ownership.

Choose AI systems your organization can understand, manage and improve. Balance business value with privacy, security, transparency, human oversight, regulatory obligations, cost and operational capacity.

RAGEmbeddingsHybrid searchRerankingPrompt engineeringTool callingMCPModel evaluationGuardrailsMonitoringData governance

Establish ownership

Map data, workflows, risks and business outcomes. Define governance, access controls, evaluation criteria, human review and clear ownership of prompts, retrieval sources and AI-generated outputs.

Keep the architecture portable

Use interfaces and standard APIs that make it easier to change providers. Keep application logic, prompts, retrieval and model settings separate, so a provider change does not mean rebuilding the product.

Build on your knowledge

Develop secure RAG pipelines, curated data sources, embeddings and reusable evaluation sets. Keep enterprise knowledge and retrieval infrastructure under organizational governance.

Choose deployment freedom

Compare managed APIs with open-weight models deployed in your own cloud or on-premises environment. Consider data residency, licensing, hardware, performance, maintenance and total cost of ownership.

Validate and improve

Benchmark multiple LLMs against real tasks for quality, safety, latency and cost. Add monitoring, human review, security testing, fallback models and continuous improvement before scaling.

The goal is to make an informed choice and stay in control. There is no need to avoid every cloud provider. A hybrid setup can work well and leave room to change models or where they run as needs evolve.

These are areas of experience, not claims of vendor certification or partnership. Services and models are chosen to fit each client’s needs, availability and governance.
