AI Validation Framework
Testable. Validatable. Trustworthy.
A pragmatic system that makes any AI implementation testable and validatable — raising data quality so that results can actually be trusted and relied on in production.

I help large companies put AI into production — and actually trust it.
Software engineer and solution architect, 7 years across healthcare, data and gaming. At Holisticon I co-author the frameworks we use to roll AI into large, regulated companies — and I lead the work that gets them shipped.

Who I am
I sit between the code and the call.
I started as a backend developer and grew into the person who owns how AI actually lands inside a big company — the architecture, the data, the way a team works around it, and the trust that lets leadership say yes. I still write production Python, TypeScript and .NET; I just also shape the decisions around them.
At Holisticon I co-authored two frameworks that make AI adoption structured and testable, and I help large companies in regulated, data-critical fields put them to work. A Master's in Management on top of Computer Science is what lets me run a delivery and talk to a board in the same week.
Engineer
Production Python, TypeScript and .NET across cloud, data and AI.
Architect
I design how AI systems are built, governed and trusted — then lead delivery.
Researcher
IEEE-published; I turn messy AI problems into shareable structure.
Signature work
Two frameworks. One idea: AI you can trust.
I co-authored two frameworks that shape how AI gets built and adopted — and I put them to work with Holisticon inside large companies.
AI-First Framework
AI as part of the team — not just a tool.
A model for how IT teams operate when AI is a first-class actor in the process — redefining roles, governance and the way work is delivered end to end.
[ i ] Both frameworks are developed at and owned by Holisticon. Shown here as authorship, not disclosure.
Real-world impact
AI, deployed where it matters.
With Holisticon I implement AI systems inside large companies — across medical, data-analytics and beyond. The specifics stay confidential; the approach stays constant: governed, validated, trustworthy.
Client details under NDA — happy to walk through them on a call.
Medical & Pharma
GenAI tooling and data-validation pipelines for a global medical company.
Data & Analytics
AI agents and validation layers for data-critical, high-stakes workflows.
Enterprise IT teams
Rolling out the AI-First way of working at organizational scale.
In the works
What I'm building right now.
Beyond client work, I'm building and co-building a few things of my own.

Founder · BuildingLaunch · Aug 2026A platform for searching and comparing real-estate information — pulling scattered property data into one place so you can compare and decide faster.
Want to test it? Let me know.DocCompan
Co-founder · CTOA document-automation platform: build advanced data and document pipelines visually from modular AI blocks. Each block does one deterministic job — extract, split, analyze, report — and AI models slot in where they help, so processes stay composable and explainable. No-code, with a community block marketplace and on-premise scaling for enterprise.

Research · PoCDual-useA research project turning WiFi sensing into a product: reading wireless signals to map spaces, build heatmaps and track moving objects. Dual-use by design — civilian and defense. Early stage, first proof of concept, built with people from Poland's Military University of Technology (WAT).

AI Implementation Lead · Solution Architect · Full-Stack Developer
I lead how AI systems are designed and rolled out inside large enterprises, and co-author two internal AI-delivery frameworks. I also work hands-on as a full-stack developer for a global medical client — building across Django + React and AI-agent tooling, focused on governed, validatable data pipelines for GenAI in pharma. Delivered a research paper and an industry talk on data validation for GenAI.

In their words.
Marcel is a great software engineer and team member. He picks up new skills quickly and applies them. He can work individually or collaboratively — I can highly recommend him for any software engineering role. Excellent Python, CI/CD, Cloud and Vue skills.
Marcel is extremely good at dealing with ambiguity, quickly providing working code to discuss and iterate on. With stricter requirements he ensures the code is well tested. I highly recommend working with Marcel — problem solving, fast learning and clear communication with engineers and stakeholders.
Working with Marcel on "Recycle.it" and other projects was a fantastic experience. His expertise in Python and web development was key to our success, and his innovative solutions and leadership were invaluable. Highly recommended.
