What we stand for

Good engineering is more than delivering code.

It is taking responsibility for the whole picture: people, systems, security, quality and the future maintainability of what gets built.

01 / OWNERSHIP

We take responsibility

We build in code, take ownership, maintain and improve. Clear commitments, honest advice and delivery you can trust.

02 / INDEPENDENCE

Enable, don't lock in

We bridge gaps, connect teams and create a real path to independence. No siloed workflows. No long-term lock-in — even with us.

03 / CRAFT

Quality is a lifestyle

Lead by example. Clean, structured, sustainable and maintainable code. We deliver what we agree and promise.

The right mindset first.
Human judgement on top.
AI as an accelerator.

Our point of view

We use AI thoughtfully, not blindly. Strong engineering fundamentals, security, context and human accountability come first. Automation belongs in the code and in the workflow — where it creates lasting value.

We are based in the Netherlands, with specialists working internationally and a company presence in Egypt. Our business is registered in the Netherlands with the Chamber of Commerce (KvK) and in Egypt.

Multidisciplinary expertise / Business & technology

Bridging the gap between technology and business.

Business perspective. Engineering depth. Quality mindset.

View Ahmed Abdel Wahab’s LinkedIn profile ↗

I bridge the gap between technology and business by combining expertise in Business Analysis, Business Intelligence and Business Strategy with a multidisciplinary background spanning Computer Science (CS), Information Technology (IT), Software Engineering (SE), Quality Assurance (QA) and DevOps.

Throughout my career, I have gained experience across cross-platform mobile testing, embedded systems, neural networks, machine learning, database technologies, kernel development and financial technology, including Forex development. This breadth enables me to connect different technical disciplines, understand complex systems and approach challenges from both technical and business perspectives.

As a big-picture thinker, I bring creativity, innovation and agility to problem-solving and strategic decision-making. I continuously work to improve technical and business quality standards while keeping them aligned with organizational objectives and client expectations.

My expertise encompasses functional and non-functional testing, contract-based testing, CI/CD processes and quality strategy development. By aligning technical frameworks and engineering practices with business objectives, I foster cross-functional collaboration, optimize processes and drive improvements in quality, efficiency and business value.

AI / Machine learning / Technology ecosystems

Technology stacks by ecosystem.

We work across leading AI platforms and select the right models, services and engineering patterns 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

Architecture / Ownership / Autonomy

Path to AI independence.

Build AI capabilities that the organization can understand, control, evolve and move—not a black box tied to one provider. Independence is a progressive engineering journey, balancing business value, security, compliance, cost and operational capacity.

1. Establish ownership

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

2. Keep the architecture portable

Use provider-agnostic interfaces, modular orchestration and standardized APIs where practical. Separate application logic, prompts, retrieval and model configuration so providers can be changed without rebuilding the product.

3. 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.

4. 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.

5. 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 informed choice and operational autonomy—not avoiding every cloud provider. A hybrid approach may be the most effective path, with the ability to switch models or deployment modes as needs change.

These are technology ecosystems and capability areas, not claims of vendor certification or partnership. Specific services and models are selected according to client requirements, availability and governance.
