Hire the Best C Programmers & Developers
in Ukraine

I help teams build and stabilize Unity games, PCVR experiences, and mobile applications. I take ownership of the technical work—from architecture and complex systems to integration, testing, and release preparation. Selected experience: - Reach The Beat: a PCVR game released on Steam. I was the sole engineer, working with an artist under my direction. - Non-game Android/iOS software: Unity client architecture, complex UI navigation, transitions, and implementation from Figma designs. Project details are confidential. - Systems-heavy 2D development: sole developer collaborating with artists, audio specialists, and narrative contributors. I can help with: - Unity architecture, gameplay systems, and reusable development tools. - Complex UI flows, mobile features, and third-party integrations. - Performance investigation, refactoring, and stabilization of existing projects. - Taking a prototype toward a maintainable, release-ready build. I work hands-on and can also provide technical direction, task breakdown, and code review. My PCVR testing setup includes a Meta Quest 3 via Quest Link and an HTC VIVE Pro 2 with Valve Index Controllers. I also use AI coding agents for scoped tasks where appropriate, while retaining responsibility for architecture, code quality, integration, and testing. I am expanding my Unreal Engine C++/Blueprints experience through an in-development PCVR project. Send a short brief through Upwork: your target platform, current project stage, main technical challenge, and what a successful first milestone looks like.

Senior developer. Turn-key solutions. Non-typical projects. Expertise: - desktop, backend development; - cross-platform applications; - C#, C/C++, Python, JavaScript, Perl, PHP - .NET, Xamarin - text/data parsing, PDF parsing; - system programming for Windows including drivers; I provide all the aspects of software development: - formalizing customer requirements; - elaborating a solution; - implementing code; - debugging; - post-delivery maintenance; I always stay behind my code. I'm capable of solving non-typical programming tasks that need ingenuity and persistence. If you have a task that nobody could cope with then here you have found the right man!

With more than 20 years of experience in the IT industry, I have developed a solid foundation in software architecture, design, and development. My expertise spans across multiple programming languages and frameworks, including C/C++, Qt/QML, C#/.NET, JavaScript, Node.js, Python, and Golang, allowing me to create robust web services, backend systems, as well as client-server and rich desktop and mobile applications. My background also includes strong capabilities in database architecture and design, specifically with PostgreSQL. I also possess extensive experience working with REST APIs, MS Bot Framework, and neural network algorithms. My proficiency in managing foreign customer relationships, along with my excellent command of English and negotiation skills, make me a valuable asset to any team. I am a self-motivated leader with a penchant for project management. I have a proven track record of effectively solving complex problems and working well in team environments. I enjoy proposing and implementing universal solutions that benefit everyone involved, and I am committed to maintaining my physical fitness in order to optimize my work performance.

Hi, my name is Arsen. I’m a Senior C++ and Python developer with 5+ years of experience building software for Linux, Windows, and embedded systems. I focus on clean, efficient, and reliable solutions for low level, backend, and performance critical tasks. What I bring to projects: • C/C++ development: STL, Boost, Boost ASIO, Qt, WinAPI, OCCI, V8, POSIX, multithreading • Python development: automation tools, data pipelines, backend logic, Django • Database engineering: Oracle, SQLite, MongoDB, data export tools, batch processing, custom type conversion • Linux systems programming: networking utilities, driver level interaction, Linux kernel headers, OpenWRT, desktop and CLI tools • Wireless and low level networking: Generic Netlink, nl80211, libnl/libmnl, Wi Fi scanning tools, protocol and frame parsing • Reliability and performance: profiling, transactional workflows, data integrity focused design, Dockerized builds, CI/CD with TeamCity • Cross platform delivery: Linux and Windows applications, Make, CMake, Conan, Git/SVN, GDB, Valgrind, Doxygen, Bash I have built tools ranging from high performance Wi Fi scanners in C that interact directly with the Linux wireless stack, to cross platform C++ command line utilities that export Oracle data into SQLite with transactional safety and performance profiling. I am comfortable working close to the system, optimizing throughput, handling large datasets, and designing software that is maintainable and stable in production. Clients usually trust me with complex backend, systems, and infrastructure related tasks where performance, correctness, and long term reliability matter. If you are looking for a developer who can work on C++, Python, Linux internals, networking, or data heavy applications, let’s talk. 🙂

C++ / Qt engineer, 20+ years. I build the software that runs machines and instruments: embedded Linux firmware, Qt/QML operator HMIs, and the cross-platform desktop workbench engineers use to configure, calibrate and log. RECENT WORK - HPLC syringe pump - control software for an analytical laboratory instrument. - Firmware, control suite and workbench for the Multistage cable-stripping machine. - ScanScore / Forte / Bandora - 8 years on cross-platform music-notation software in Qt: optical score recognition, MIDI, PDF export. - Debian POS server - multithreaded C++ service, PostgreSQL, ESC/POS thermal printing, deployed onsite. 18,000 hours on Upwork at 100% Job Success, Top Rated Plus. WHAT YOU GET I lead a small Lviv team - firmware, HMI and desktop under one contract - and I stay hands-on in C++/Qt myself. You talk to me, not to an account manager. - Embedded & HMI: STM32, Arduino, embedded Linux, Qt/QML touch panels, industrial operator screens. - Desktop: cross-platform Qt for Linux and Windows; C#/.NET (WPF, WinForms, DevExpress) when the Windows side needs it. - Data: PostgreSQL, MS SQL, multithreaded C++ services, reporting, printing, installers. HOW I RUN PROJECTS - YOU SEE EVERYTHING Offshore teams fail on visibility, not on code. The process is built to remove that risk: - Private Jira server - you get an account and watch the board in real time. - Every code change is linked to its Jira task. Nothing lands untracked. - Code lives on our BitBucket Git server; you get access. - Every reported developer hour carries the developer's own comment explaining it. - Weekly and monthly reports, generated - not improvised. - A working demo build every week. You judge progress by running it, not by reading a status update. Scope is agreed as Work / Time / Budget with defined milestones before anything starts. Background: SoftServe 2002-2008, developer to tech lead; then my own team since 2014. ALSO AVAILABLE: legacy Windows rescue - MFC, Win32, COM/ATL, Visual C++ 6.0, WinForms/.NET. The desktop applications other developers won't touch. I have been maintaining and modernizing them since 2002. Send me the machine, the instrument or the old application - I will tell you honestly whether we are the right fit.
