Über mich
Compared to a big consultancy, you get the same senior-level depth directly, without paying for a bench of juniors behind a partner's name. Compared to a generalist freelancer, you get someone who owns the whole stack — cloud architecture, data architecture, infrastructure, security, networking — instead of one narrow slice.
Low friction to start: EU citizen, no visa delays, €1M professional indemnity insurance already in place, top-tier Microsoft certifications kept current.
If your project needs someone who designs it right, builds it, and does both at a fair price, get in touch.
Rate and CV on request.
