AWS that runs. And pays off.
I'm Tomislav Pree, a cloud architect from Mainz. I secure AWS environments, cut costs and move servers to the cloud without downtime. As a fixed-price project if you have no cloud team of your own, or as a freelancer inside your team when it needs reinforcement.
Lower AWS costs
Environments that were never optimised usually cost 20 to 30 percent less afterwards, with nothing running slower.
Migration without downtime
Servers move in stages, and every step has a tested way back.
Secure and auditable
Separate accounts and traceable changes, with evidence for NIS2 and auditors.
Three ways to an AWS environment that no longer keeps you up at night
- Security & AWS foundationTest and production separated, access under control, every change traceable. With evidence for NIS2 and auditors.from €990
- Cloud migration to AWSMove out of your own server room and onto AWS in stages, without downtime. With an honest cost comparison up front.from €1,490
- AWS costs & scalingFirst cut your AWS bill, then rebuild your software so load peaks and new customers stop being a risk.from €2,900
