Hey guys, just wanted to drop a quick note to let you know that I have recently joined JUST EAT as a Principle Engineer, since some of you have been asking on LinkedIn and at conferences.

For those of you based in UK and Europe you might have heard of us – we are the leaders in the online food delivery space, and have been expanding rapidly in the last couple of years. In fact, we’re still actively looking for talented .Net developers to join us, and if you have experience with Xamarin then we definitely wanna hear from you! Check out our jobs page.

As a company, JUST EAT is very technology focused and amongst many perks everyone is entitled to a budget of £1000 + 5 days for training/conferences a year. And we also host many meetup events in our office near City Thameslink.

Keep an eye on our tech blog and github repo to see what we’re up to. A few of us will also be attending BuildStuff this week so feel free to come talk to us. I’ll be giving a new talk on 7 Ineffective Coding Habits Many F# Programmers Don’t Have, as well as an introductory talk on Elm (with plenty of live coding), so hope to see you in Vilnius!

Hi, I’m Yan. I’m an AWS Serverless Hero and I help companies go faster for less by adopting serverless technologies successfully.

Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.

Hire me.


Skill up your serverless game with this hands-on workshop.

My 4-week Production-Ready Serverless online workshop is back!

This course takes you through building a production-ready serverless web application from testing, deployment, security, all the way through to observability. The motivation for this course is to give you hands-on experience building something with serverless technologies while giving you a broader view of the challenges you will face as the architecture matures and expands.

We will start at the basics and give you a firm introduction to Lambda and all the relevant concepts and service features (including the latest announcements in 2020). And then gradually ramping up and cover a wide array of topics such as API security, testing strategies, CI/CD, secret management, and operational best practices for monitoring and troubleshooting.

If you enrol now you can also get 15% OFF with the promo code “yanprs15”.
