Data Wrangling with JavaScript

My book Data Wrangling with JavaScript is live! If you are interested in data transformation, analysis and visualization please grab a copy. If not, please help me promote it! Want to give feedback? See my email address at the bottom of the page.

Bio

I have a long history in software development with many years in apps, web apps, backends, serious games, simulations and VR. I make technology work for business. I architect and build bespoke software solutions that span multiple platforms.

I have years of experience managing development teams, preparing technical strategies and creation of software products. I can explain complicated technology to senior management. I have delivered cutting-edge products in fast-paced and high-pressure environments. I know how to focus and prioritize to get the important things done.

I am a passionate technologist and agile practitioner. I have had great success with TDD and am convinced of its ability to produce better code that stabilizes more quickly while being evolved rapidly. I’m a fan of functional programming and its potential for safety, predictability & concurrency.

I contribute to open source and have founded multiple industry groups.

I’m also a keen systems trader, currently trading stocks on the ASX and building algorithmic strategies for CFDs trading.

Please find me on LinkedIn for the full list of employment history, projects and publications.

Data-Forge and Data-Forge Notebook

Data-Forge is my open-source data transformation and analysis toolkit for JavaScript/TypeScript. It is inspired by Pandas and LINQ and is my goto tool for slicing and dicing data.

Read more about it on my blog The Data Wrangler.

You can find Data-Forge on Github or take a look at the official Data-Forge landing page.

I’m also building a Notebook-style product for data analysis, transformation and visualization in JavaScript (kind of like an IDE for working with data in JavaScript). It’s called Data-Forge Notebook and the early access program is now open. I have a demo video online, please take a look.

Other open-source

I have plenty of other open source code on my personal Github account. Please have a browse. If something looks interesting, but isn’t well documented, please reach out and let me know about it!

I also did a lot of open-source work while at Real Serious Games, you’ll find some very useful code for work with Unity and Node.js on the Real Serious Games Github account.

Market Wizard

I’ve created a stock market simulator called Market Wizard which has a small, but loyal following.

I use this for my own paper trading, although mostly now I do backtesting because paper trading is too slow and only useful once a trading strategy has passed through many rounds of historical and statistical testing.

Blogs

I have two blogs.

The Data Wrangler is my current blog - with writings on data analysis and general coding.

What could possibly go wrong? is my older game tech blog, I no longer update this - but it’s preserved for posterity and to occasionaly remind myself of just much I have written.
