Lately my work is about integrating Bitcoin-related functionality in websites or developing special purpose apps, like a bitcoin trading bot or a websocket chat. It involved various technologies: node.js, websockets, Ruby, Sinatra framework, Blockchain.info API, PayPal API.
I've integrated a number of payment systems in several websites, which included PayPal, Bitcoin (native and via Blockchain.info API) and russian WebMoney, Yandex.Money, QIWI, Robokassa. All payment processors utilize mainly same principles, so it's no problem to learn and integrate something new quickly.
My work included creation of web grabbers and parsers that process information from external websites, for example to fill up an online store database. Also setting up and administrating Linux/FreeBSD VPS servers: installation and configuration of Apache, PHP, MySQL, Python and some other uncommon software.
Aside from pure web, I've developed Python and Ruby scripts for various services. A part of that was developing Bitcoin-related services, including API communication with bitcoind daemon, automated receiving/sending Bitcoin payments, trading on BTC exchanges via their API, and other stuff.
I'm looking for interesting work opportunities that would let me develop my skills and acquire new ones. Cryptocurrencies are especially interesting to me, but if it's not the case, no problem.
Most likely I can be useful to solve your programming issues, so feel free to contact me.
