Welcome to QuantumJS. I'm Nikos and I build web applications and train developers. I love to give inspiring talks including JavaScript, TypeScript, Ember, React and Node.js. I can be booked to train you in your offices or online. Both as a group or one-to-one.

Upcoming events

Webpack in Munich May 8th - 10th 2018

Learn webpack or secrets of world class developer teams in Munich.

This event has various sessions including a high-level overview on how to configure Webpack. A masterclass with Tobias where we will show you how to write loaders and plugins, discuss webpack internals in detail, and help you to solve your issues and speed up your build. And also Nikos' seminar on the secrets of building software teams.

AI and data science May 28th 2018

for executives and tomorrow's decision makers

This event is geared towards all non-technical decision makers (CEOs, managers, heads of divisions, startup founders, etc.) who want to learn what data science is, and how it can be used within their company.

Training offerings

Corporate training

I would love to come to you and train some of your people in the latest web technologies and techniques!

I offer the below courses. I run each course over 3-5 days. I can tailor each course depending on your team's needs. I can also offer combination classes by mix and matching sections.

JS data-types, functional programming, promises, ES2015, Webpack js building and VanillaJS DOM manipulation.

JavaScript vs TypeScript, TypeScript versions, Typings, React usage, Angular 2 usage, tsconfig and Webpack ts building.

Component design, publishing to npm, reusability. How to make a router, popup, terminal and datagrid components.

Application patterns, composing Typescript components, making a space invaders game.

Cloud based

I started this YouTube channel in 2016 to teach programing. All code videos have the source on Github. Feel free to pop over and be entertained.

Application design and development

I would love to build you an app! I can organise a team of developers and start working on your requirements. To keep things simple I prefer to hire out my coders via an hourly or daily rate rather than fixed price projects. My team uses Trello for task management and project milestones.

Companies I've worked with

Some nice words about my work

Firstly I want to say I came to see you at an event recently, you were fantastic, as a recruiter I learned a lot about the language I recruit for and am very grateful for the insights you provided. I'm already relishing the next opportunity I get to attend one of your events and highly recommend you to any developer or recruiter looking to learn more about TypeScript (a super set of JavaScript as I learnt from you Nikos)

Alexander Recruitment consultant

Me and Nikos first talked in a support channel for react-native. He was very quick to respond and even quicker to offer extraordinary help with react-native. For me this was the first time I was in contact with react-native. Have done a lot of programming before in both javascript and other languages. But react-native is a lot more than just the programming aspect. Nikos guided me through the steps of how to troubleshoot an app that does not work. Showed me and explained how to structure a react-native app and also explained in great detail of why it should be designed in this certain way all at the same time as he answered all my questions. Nikos has an awesome vibe when it comes to teaching people and is also super friendly. I could not have wished for a better introduction for react-native than I got from Nikos. He would be the first person I would hire for any react-native project. This is a person I hope I will keep as a friend in the future as well.

Alexander Freelance developer

Nikos provided my team with tailor made JavaScript training that changed the way we leverage our analytics code. With his help we were able to identify and resolve issues within our code and then redeploy quickly.

Eric Marketing Innovation Manager at Dixons Carphone

Training with Nikos really helped me to gain the confidence to bootstrap my career in Tech. I am very grateful for the time I spent with him and I needed advice the most

Julien developer at Clearscore

Nikos is an excellent trainer. I'd had little success being self taught, but he was quickly able to identify the technical areas I needed to improve, in order to move forward. With his help, I was able to land my first job as a junior frontend developer!

Chris front-end developer

At the very beginning my career I was lucky enough to have Nikos there to help me advance my skills. He is a brilliant teacher.
