Consulting
Do you have questions concerning your IT needs? I could provide some insights on how to put different bits and pieces together. Service architecture, cost-efficient infrastructure, robust software stacks, people, recruitment, setting up and optimization of processes. Find me an interesting problem, I might have a solution.
Programming
While my time is limited I like to take up a project from time to time. Get me interested, show how it benefits your customers. With the right tech stack and sufficient level of challenge I may be available to help.
Operations
Some servers running that need on-going administration, care and monitoring? Need some individual, focused approach that service provider's customer service just cannot provide? Maybe I'm the person who can do that for you.

Personal Profile
With years of experience I developed expertise from programming, through operations and finally into technical leadership and management. I had opportunities to gain knowledge in every aspect of software development.
I'm an engineer at heart, finding a lot of fun in creating things and making them happen. Software, processes, teams or even car audio system - I like to analyze, tinker and improve efficiency. Keeping in touch with technology is very important to me and constantly learning new things both at work and as a hobby.
I'm currently settled in Cambridge, UK area.
