Building phone bots using FreeSwitch, Python and Generative AI technologies.Doing what ever is needed for success - from product vision, team building, cloud architecture, fune-tuning of AI models, to low level debugging of nasty deadlocks and race conditions between Python and C code.

First web developer, then web3 & blockchain developer, then C and Python developer on conversational AI project.

Implemented features to make our users happy, and company to earn more money, kept Yandex.Browser in sync with Chromium base and maintained.This includes writing new features, evaluating them through AB testing, taking long debugging sessions on multiple platforms (Android, Linux, Windows, MacOS), writing tests (in C++, Java, Kotlin, Python and JavaScript), and jumping into unknown or familiar code (like Chromium's content layer, Blink, and custom android specific code), even patching… Show more Implemented features to make our users happy, and company to earn more money, kept Yandex.Browser in sync with Chromium base and maintained.This includes writing new features, evaluating them through AB testing, taking long debugging sessions on multiple platforms (Android, Linux, Windows, MacOS), writing tests (in C++, Java, Kotlin, Python and JavaScript), and jumping into unknown or familiar code (like Chromium's content layer, Blink, and custom android specific code), even patching C++ and Python backend code, if needed.

Transformed abandoned, almost unmaintainable code, into profitable SaaS business with less bugs and more features, using all skills at my disposal and working under pressure. The core of the project is a cluster of video streaming servers (hitrow), with REST API and custom async HTTP protocol implementation, written in pure C (using epoll). Implementing complex features, fixing rare production bugs, DevOps and SysAdmin, communicating with clients, designing architecture, writing C, bash,… Show more Transformed abandoned, almost unmaintainable code, into profitable SaaS business with less bugs and more features, using all skills at my disposal and working under pressure.

Implementing complex features, fixing rare production bugs, DevOps and SysAdmin, communicating with clients, designing architecture, writing C, bash, and Node.js code, disassembling-fixing-reassembling custom HTTP library, and then negotiating purchase of the source code so I don’t have to do it again, all that was part of the job.

Helped small team (mostly students) to turn R&D project into commercial opportunity, by researching, architecting framework, designing APIs and writing C++, C, and Lua code.Building R&D proof of concept and that turning it into commercial project. The project was GUI-Framework and run-time environment for applications written in Lua, for extremely resource constrained set-top boxes. The framework is itself written mostly in C++, with low level parts in C and high level in Lua.
