Clarity before activity
The first task is to understand which decision actually needs to be made.
Jan Paul Buchwald
Independent software architect. Founder. Angel investor.
I have more than 20 years of experience designing and evolving complex software systems. I work at the point where business decisions, product direction and engineering reality have to line up.
Architecture in business context
Technical depth, connected to consequences
My work has taken me across complex systems, different industries and organisations at different stages of maturity.
I am hands-on enough to understand the implementation reality, but my role is not to fill a development backlog. It is to help teams frame difficult questions, make sound technical decisions and connect those decisions to product and business outcomes.
Through YOPITER, I take on architecture, AI integration and technical-strategy mandates for established companies and growing technology teams.
Both sides of the table
Perspective from company building and investing
Alongside consulting, I have co-founded companies, advised early-stage teams and invested in technology ventures.
This changes how I look at architecture. Technical elegance matters, but it has to coexist with timing, capital, organisational capability, product focus and commercial reality.
The same perspective informs YOPITER’s investments: strong technology is most valuable when it is attached to a clear problem and a credible path into real use.

Working principles
How I approach the work
Trade-offs made explicit
Architecture is not a search for a universally correct answer. It is the disciplined handling of consequences.
Close to implementation
A decision is only useful if the team can apply it under real constraints.
Independent judgement
Recommendations should follow the problem, not a preferred vendor, framework or technology.
