About me

I am looking for jobs that challenge me in positive ways. What delights me are complex problems and large sites, with many users and page views.

I speak about software architecture at conferences in Europe and Asia. In my spare time, I blog about my crazy side projects and give a hand in the community through initiatives like Andela, a company that provides work and mentorship to African developers.

Leaving a positive footprint is important to me.

I earned my chops on a ZX Spectrum, which I love to bits, and I am entirely self taught. I love learning stuff and practicing my trade. Whatever the coding topic, it's probably something I'd love to chat about.

Trayport is the European leader in software for commodity trading, in particular for energy, coal, emissions and oil.

I lead the development and maintenance of a series of large .Net projects such as our pre-trade, real time risk application, Trayport EMA Gateway.

Community

Talks

I have given many talks over the past five years in front of thousands of people. A full list of my talks is available. For example,

DotNext Moscow

DotNext is the premier Russian conference on the .Net ecosystem. I have two main room talks, one about the architecture of Stack Overflow and the other about the optimization of our tag query service, from SQL to CUDA.

DotNext Helsinki is a small extension of the main Moscow conference held at the wonderful Microsoft Nokia headquarters. I gave a small audience version of the architecture of Stack Overflow talk.

JSConf Asia is one of the biggest developer conferences in Singapore. I talked about the architecture of Stack Overflow to a few hundred enthusiastic developers.

Writings

I am active as a blogger and on the Stack Exchange network. As a blogger, some of my post were featured on the home page of Hacker News and received good feedback.

Some popular blog posts:

In the Stack Exchange network I wrote many highly upvoted (100+) posts, both prior and during my tenure as a Stack employee.

Outreach

For three years now I've held a mentorship position at Andela

The Andela mentorship connects Western mentoring developers with African mentees. I am very happy to help people in developing countries improve their skills as knowledge can and should be freely donated for the betterment of all, especially for those who have less opportunities.

I have been writing up some of my algorithms and data structure lessons as ongoing blog posts.

Projects

Programming is my job but also my passion. I work on computer and technology related projects in my spare time all year round. Here are a few of my recent ones.

Blasteroids

Blasteroids is an 80's arcade space shoot-em-up, adapted to modern times. It's still an early alpha as the game is missing features, however it is fully playable and fun! The game is written in vanilla JavaScript. It works only on desktops.

My homebrew computer

I wanted to understand how transistors are assembled to make gates and how gates are assembled to make usable computer parts. I am attempting to build a computer from scratch and blogging about it.

z80

z80 is, unsurprisingly, a z80 emulator library, written in C# using TDD. I am a huge fan of this CPU and its assembly language and developing it was a pleasure.
