- Besides being a new joiner in the team, I jumped into the urgent partner request and took situational leadership over the backend part. That was not rocket science but required quite some effort to understand the codebase and communicate findings. As a result, quite a big brand become a happy Partner, and the EOY revenue forecast showed €10M more.


- Incoming questions from internal stakeholders and support requests were answered by a few senior engineers only. It took a ton of time and energy from them. I planned, aligned, and conducted a week-long first responder boot camp for five new joiners to share knowledge and equip them with a toolset. As an outcome, new joiners got practical knowledge and a toolset to answer support requests, and the pressure on experienced engineers slightly decreased.
Solution-driven Senior Software Engineer with expertise in diverse technical skills, problem-solving, and cross-cultural communication. Proficient in project ownership, from conceptualization to production, with a product-oriented mindset. Self-motivated and highly adaptable in fast-paced, iterative environments.

- Proven ability to multitask and handle complex projects
- Strong asynchronous communication and collaboration skills
- Committed to continuous learning and professional growth
- Comfortable working remotely and adapting to changing priorities
- Excellent problem-solving abilities and attention to detail
- Feedback-driven culture: trust and transparency, regular and meaningful one-to-one meetings.
- Well-tuned work processes within the team: code review, mandatory test coverage, and decision autonomy.
- I'm not interested in joining teams with micromanagement and overloaded leads.

Position: Ruby Tech/Team Lead
Category: Ruby
Experience: 6 years | English: fluent

* Moved a project of more than 10 services from Heroku to Kubernetes in Google Cloud.
* Held a major UI redesign as well as software refactoring for the aforementioned project.
* Successfully duplicated the aforementioned project for a slightly different market.
* Created a Skill Matrix Template for all major development and infrastructure stacks.
* Success rate of my mentees' personal development plans is about 80% as well as mentees of other mentors working by my methodology. Disclaimer: it is not statistical data, only my personal feelings, also I have not solidified that methodology, work in progress.
Wear several hats:
* A lead of a pizza-sized team (5 people including me right now) in HR & Media domain, service-oriented architecture project for over 3 years.
* A technical lead on Development and Infrastructure branches for over 2 years.
* A mentor for 5 middle-to-senior developers outside my team, and, sometimes, outside my Ruby stack in the scope of performance reviews, skill matrices, and personal development plans as well as a lead of such fellow mentors for almost a year.

Basically, I'm accountable for everything about development and architecture (Ruby, Rails), infrastructure (Docker, Kubernetes, Helm), and professional skills growth of developers.

I do not do frontend at all but I know how modern FE works, I can write JS, I know how to work hand in hand with FE engineers. On the other hand, I have a piece of good knowledge of DevOps.

By no means, I am the best engineer, architect, or team leader. Rarely do I have or know the best solution for a problem that is supposed to work right away based on long-time experience. But I believe that by asking good questions and doing validated learning (technics from The Lean Startup and The Mom Test books) eventually we can succeed in any process whether it is technical or people-oriented.
We are a good fit if you looking for an ambitious and experimenting engineering lead and/or architect. I am not interested in a solely engineering role.

Multi Language Bindings Generator writter in Rust with proc macros. Similar to UniFFI from Mozilla but supports more languages - C/C++, C#/CLI, Java, Swift, JS (CEF + Electron).
For the past decade or more my main specialization was Android (from phones to STBs to fully embedded devices). Most of those projects required good knowledge of the C++ language and later also Rust. From time to time I was also involved in Flutter projects and briefly React Native.

I have experience with many different technologies like WebRTC, video streaming / transcoding, 3D rendering (OpenGL to Vulkan to WebGPU), networking (from raw TCP / UDP sockets to gRPC / ProtoBuf to HTTP / WebSockets to WebTransport), Bluetooth LE, Jetpack Compose, JNI/NDK, Code Generation and many others.

One of the latest highlights is the implementation of multi language bindings generator for the Rust project. It was similar to Mozilla's UniFFI but was able to automatically create bindings to C, C++, C# (via C++/CLI), Swift, Kotlin and JavaScript (both CEF and Electron) languages by using procedural macros in Rust.

Always eager to learn new perspective and innovative technologies.

My favorite catch phrase: "Rust did to C++ what Kotlin did to Java" !

Some keywords:
- Android - SDK / NDK, Room, BLE, RxJava, Jetpack libraries
- Rust - proc macros, async, actix-web, WGPU
- Kotlin - coroutines, compose, retrofit / okhttp / ktor, jackson / gson / kotlin serialization, Dagger / Koin
- Flutter - GetIT, BLoC, dio, RxDart, Providers, intl, firebase,
- Architectures - MVP, MVVM, MVI, SOLID
- Databases - MySQL, SQLite
- Networking - TCP/UDP, gRPC / protobuf, HTTP, WebRTC, WebSockets, WebTransport, BLE
- Codecs - H.264, H.265, VP9 with SVC

Summary:
- main specialization - Android, Rust
- great at Android, Kotlin, Rust
- good at Flutter, Java, C++, Dart languages
Don't really like AOSP or system-level programming in general.
I know Flutter but would like to avoid it.

External system integration.
Hands-on experience with HTTP/3.
Throughout my career I have developed C++ applications in areas like Smart TV, Video streaming, Enterprise. These applications were running on Embedded platforms, Desktop, Cloud. Each project which I was working on had it's own requirements in optimization, libraries integration, testing. That's why I know pros and cons of using C++ in different conditions which features can be used and which not.
Well organized work. Rust or new C++11 project.

- 2 years of freelance. I worked as a full-stack dev, developing apps from zero to production. These apps mainly were focused on selling goods.

- 3 years of a full-time job at ScaleTools AG as a web developer. I was a part of a team working on a cloud-based app. My responsibilities were designing the internal architecture of apps, writing code, and supporting it. 
Later I was a leading developer responsible for several products that were parts of a microservice infrastructure.

I've decided to change the tech stack and switch to Rust. I wrote several rust-based pet projects such as a TUI bookmark manager, and a simple client-server GUI game based on a TCP connection. I'm interested in web3, blockchain, desktop, and system programming.
