I had the pleasure to work with Alf Kristian as a client in BN Bolig. His role in our project was as a senior full-stack developer and architect, where he was a key resource in selecting a future proof technology stack, developing a scalable and agile front/backend, implementing infrastructure and mentoring other developers.

His technology skills and deliverables are unquestionable, but what we found most valuable was his ability to identify week spots and on his own initiative fill in the blanks. Key areas where Alf Kristian has taken responsibility outside his defined role is in security issues, the interconnection between development and operations, development processes, onboarding of new employees and mapping of complex and (often) diverging user needs to delivered solution.

Alf Kristian is committed and takes ownership in his assignments. I have personally learned a lot from working with him and would not hesitate to work with him again if I get the opportunity.

Alf Kristian is the personification of one of my favourite books - Smart and Gets Things Done. Having tried (but alas failed) to employ him a few years ago, I was lucky enough to hire him as a consultant on our Smart Home project at Hafslund. I was particularly impressed by his attention to detail, his thoroughness and his ability to just make it work. Our office hipster coffee club mourns his loss, as does the rest of our team. I would wholeheartedly recommend Alf Kristian for any project.

I learned to know Alf Kristian while he was a consultant with us in the Analytics team in Telenor Digital. He impressed me with his attitude towards commitment, and his ability to get stuff done. We learned a lot together about Clojure and AWS while he worked on parts of our ETL pipeline, and his code - concise, readable, well tested - is still running in our production systems (2014-10.)

He is a great team-mate, and I would strongly recommend his services as a software developer - or Kodemaker if you like. If I got another chance at having him on my team, I'd grab it.

Alf Kristian is by far one of the most talented developers I've ever worked with, and it was a true pleasure to have him on my team. We worked together for a year on a distributed custom build project consisting of 100 people with six development teams in two geographical locations. Alf Kristian soon established him self as lead developer on the team and a valued resource in the project. He's highly productive, solves the toughest and most complex tasks, and delivers highly maintainable code with few bugs. He identifies problems and weaknesses in both process, code and architecture and suggests ways of solving them, but still remains loyal to the decisions made by the team or project. He's easy going and a true team player, helping out whenever he can. It was a true pleasure to have him on my team, I learned a lot from him, and hope to be working with him again in the future. If you're looking for a trustworthy, highly skilled developer/architect for your project, small or large, then you can't go wrong with Alf Kristian. Highly recommended!

Alf Kristian is a passionate and talented developer. I had the pleasure of working with Alf Kristian for six years in Knowit. In addition to being a great developer and consultant, he was involved in Knowit´s strategy for knowledge management and technology. Alf Kristian has been a strong promoter of functional programing languages and his competence and enthusiasm on the subject was partly responsible for the fact that Knowit was one of the first norwegian consultancies to put a system written in Scala in production.

Alf Kristian is a very conscientious person and I wish him the best of luck with his new job and give him my warmest recommendations.

Tiden hos oss i Toll og avgifts direktoratet, sammen med Alf Kristian var behagelig. Alfs bidrag med kompetanse, kunnskap, kreativitet, samt oppførselen og væremåte ga oss og teamet store felles løft. Ønsket mitt var å fortsette samarbeidet, derved »slippe» å anbefale ham. Siden så ikke ble, umiddelbart og noe skal fremheves må det være blant hans mange gode egenskaper: Raskt å tilegne seg oversikt. Se muligheter og løsninger i alle spekter fra programmeringsteknisk detaljnivå til overordnet informasjonsflyt. Profesjonell opptreden, tørre å ta tak i utfordringer på alle nivåer.
