Golang programmer
Working as back-end developer for site https://packbet.com/
This site is a platform of card and board games.
My responsibility is to write the site infrastructure as well as the development and implementation of the logic of various games.
One of the projects was open source:
https://github.com/geneva-lake/golang-socketio
it was completion of the library implementing the protocol Socket.io. The library originally used only websockets, I added a long polling and an upgrade from long polling to websockets.

Freelance
Developer
Programming on Raspberry Pi.
Creating a TCP server, working with serial port and low level graphics. Raspbian Lite was installed on device. The task was to imitate the aircraft device for the cockpit simulator. Raspberry had to receive signals by TCP protocol and from keyboard through serial port and display graphics according to them. Software was written on C language.
Working as a frontend developer for site:
http://e-fish.com.cn/
My responsibilitiies were: converting graphics mockups into HTML using Twitter Bootstrap 3, CSS, jQuery and Razor, creating adaptive mark up.

Golang/C programmer
Implementing SIP stack on golang using the existing libraries on C. The PJSIP library was used . The task was setted in the course of building a system of modern intercoms. This system allows people to make calls from the intercom to the mobile application using the SIP protocol. The architecture of the system was chosen as follows: audio data from the microcontroller of the intercom in the form of RTP packets through web sockets arrives to intermediate server that makes a SIP call through a proxy to a SIP client (mobile application) and, after establishing communication, provides duplex transmission of audio.
I solved the following tasks.
- Implementation of an intermediate asynchronous and multithreaded server between the microcontrollers of intercoms and SIP clients, providing the possibility of multiple parallel calls. The server architecture was built taking into account the requirement of minimum resource utilization. Reception and transmission of RTP packets between the server and the SIP client was conducted over a direct UDP channel without recoding and timing using low-level PJSIP library constructs based on the implementation of the proactor pattern. In general, the SIP part of the server was written on the C, the web part, work with websockets was written on go.
- Writing a web interface for this server for testing and managing the state of the program
- Development on go intercom emulator (web socket client) for server testing with the ability to realize various contingencies
- Implementation of automatic testing

My own projects
Programming
Backend for mobile apps in golang inspirated by parse.com, based on a gocraft/web framework
https://github.com/geneva-lake/elesh
Application counts requests, provides rest api for checking trial time, checking sessions and storing some text information. Also through web interface it provide information about installed devices, stored text information and api request count by day represented as graph. Web interface is SPA on a base angularjs. elesh uses mongodb for storing devices information and influxdb for api requests statistics.
Very simple example of react flux application.

Backend is written on golang. Simplicity of project allows to understand the basic structural components of flux without blurring the focus on not necessary features.
