Courses & workshops
A day at your office, working on your own tasks. Not a generic course where half the examples involve a webshop that sells coffee.
The format is usually the same: we spend the morning on the technical side, and the afternoon with people working on their own tasks while I move around the room. That is where it actually sticks.
I always ask for two or three concrete tasks from you in advance, then build the material around those instead of using my own examples.

Process
How it works
Four steps. You know what happens when, and you can stop after any of them.
- 01
Your tasks up front
I ask for two or three concrete tasks people spend time on every week, then build the day around those instead of using my own examples from someone else's industry.
- 02
Morning: the technical part
Short and concrete. Not a talk about what the technology is, everyone has heard that, but how to actually get something usable out of it.
- 03
Afternoon: hands on
People work on their own tasks while I move around the room. That is where it sticks. I have never seen anyone change habits from watching a screen all day.
- 04
Material you keep
A follow-up document with what we built, including what ended up working. New colleagues can catch up later without sitting through the same walkthrough again.

Who does the work
I am the person you will be working with
My name is Mikkel and I have been building for the web since 2010. There is no project manager in between, and you will not get a junior on the job because the senior was busy. What you agree is what gets built, and I am the one building it.
Day to day I am a partner at Bigum&Co, and I have worked on more than 400 projects across ecommerce, pharma, construction and the public sector. Call or write — I usually reply the same day, and I will say straight away if the job is not a fit.

What people say about me
Mikkel Tschentscher is my lifeline when something is urgent and nobody else can work it out.
Torben Wiese(translated from Danish) Mikkel is a man after my own heart. Executes at lightning speed, has an eye for detail and is always there when you need him. It does not get better than that.
Tini Owild(translated from Danish) He is simply a pro. Highly competent and precise, brings good input, and is a huge support.
Carsten Johan Thessen(translated from Danish)
