About Raphael

We should talk

...if you want to build a product in complex and volatile context with a decent degree of uncertainty.
...if you want to explore frontier technology and assess it's impact and benefits for your business.
...if you want to move your technology organization and team(s) forward, aligned with your strategy and your customer's needs.
...if you need somebody on your team, who values results, people and system integrity.

Because

I am a product minded and result oriented systems architect with an hands-on approach to both engineering and consulting. I deeply care about the challenges of my customers, the development craft and possibilities of new technologies.
As seen from my prior experiences, my focus has always been to maximize value with the use of technology, never using a specific technology for it's own sake.

Being context aware, I am as proud of the system and product development efforts I've been a part of, as of the features and products we didn't build. Either because they were unfeasible or wouldn't move the needle for a customer.

Therefore

I am well aware of the commercial risks my clients take on, in order to produce something of great value. Thus, I try to align my rate with the overall duration of an assigment and the risk profile. Additionally I don't shy away from travels and on-site meetings/workshops when needed or demanded.

To conclude

If this resonates with you, I am looking forward to learning more about you and your challenges. Let's talk!
