Networking / Testing / Monitoring / DevOps
We can assist in designing information systems and online services, from the initial sketches to the selection of components. After more than 20 years of experience we like to believe that our technical intuition is grounded in a little more than hearsay and guesses.
We are familiar with Linux and other Unices, relational, OLAP and key-value databases, message queues, containers, virtualisation as well as actual physical hardware.
We have experience developing for tiny micro-controllers and large scale server farms and many things in between, using languages from C and assembly to modern type-safe languages such as OCaml, as well as constraint solvers and logic programming.
We are used to carry a pager at all time and can provide 7/7 24/24 support.
