Position: Lead Software Engineer (Rust)
Category: C++
Experience: 11 years | English: upper

I'm maintaining a bunch of own Open Source projects (frontend/backend libraries, server automation tools, popular Docker images with over 1M pulls combined), as well as co-maintaining a couple of built by others.

Active contributor to many Open Source projects, here is a list of well known projects I contributed code to that you may recognize:
jQuery, Linux Kernel, HHVM, Polymer, WebComponents.js, ownCloud, fabric.js, PulseAudio, TinyMCE, WebTorrent, Emscripten, lodash, Redux, PHP, simple-peer, pfSense, mediasoup, GStreamer...
13 years of experience as a software engineer.

Lately worked a lot with WebRTC, GStreamer, mediasoup (co-maintainer) and Rust, built large-scale streaming/recording ecosystem of products/features from scratch (architecture, backend implementation and frontend SDK for the rest of the team to integrate with), mostly in Rust. Before that worked on modernizing/rewriting legacy PHP/JS/TS codebases for scalability, high availability, observability and increased performance (orders of magnitude lower latency or increased throughput).

Know PHP and TypeScript (and JavaScript, LiveScript, CoffeeScript) very well, but nowadays prefer Rust whenever applicable and will only consider PHP if it is being actively migrated from.

Know the basics of modern cryptography, interested in distributed privacy-centric systems (have built own special-purpose DHT from scratch).

Packing software into containers and running with Docker since 2014, before it was cool :)

Few notes about past experience:
* always worked on very custom projects that do not have of-the-shelf solutions
* can debug and fix complex code, occasionally even obfuscated if there is no other way around it
* strongly self-motivated engineer with ability to focus on the task and find solution without any supervision and guidance, will reach-out for help as needed
* not very skilled at motivating and managing others
* can and will argue about solutions that I think are more appropriate (simply because I'm working with team and focus on result, not participation), you should be ready and open-minded
* money is important, but product vision and team culture is even more important
Remote only (can be in office in Kyiv occasionally, no relocate, sorry).
Product company only.
Custom unique products.

Open Source software is the first priority.
Salary in crypto currencies (including stablecoins) is preferrable.
