Hi there! For the last 7 years I have been professionally helping clients turn their ideas into a product. With proven ability of understanding customers' needs and outside the box thinking I am always eager to do the things right. If you want energetic, positive thinking problem solver with always fresh ideas in mind, I'm your man. Among areas of my expertise you might be interested in: - Qt - C++ - Rust - Golang - Blockchain - Cryptocurrency - Mobile, Desktop and Crossplatform Development.

I am a senior software engineer with strong experience across system-level and application-level development. I work with C#, C++, Python, and .NET, building high-performance backend systems and clean desktop or embedded firmware, mobile applications. I have solid experience with WPF for desktop apps, and also iOS and macOS development when product needs cross-platform support. Main Tech Skills: ⭐ Languages: C#, C++, Python, Swift, Objective-C, Bash, PowerShell ⭐ Frameworks & Platforms: .NET Core, ASP.NET, Entity Framework, Dapper, WPF, WinForms, Xamarin, MAUI, iOS, macOS ⭐ Systems & Low-Level: Linux, Linux Kernel, POSIX, Multithreading, Concurrency, Parallel Programming, Memory Management, Pointers, IPC, Signals, Socket Programming, Low-Level Debugging, System Calls ⭐ Backend & APIs: REST APIs, gRPC, WebSockets, Microservices Architecture, System Design, Distributed Systems, API Security, OAuth2, JWT, Rate Limiting ⭐ Databases & Caching: PostgreSQL, MySQL, MongoDB, SQLite, Redis, Indexing, Query Optimization ⭐ DevOps & Cloud: Docker, Kubernetes, CI/CD, GitHub Actions, Azure DevOps, AWS, Nginx, Linux Server Management ⭐ Tools & Engineering: Git, CMake, MSBuild, Makefile, Visual Studio, VS Code, CLion, Xcode ⭐ Testing & Quality: Unit Testing, Integration Testing, Test Automation, TDD, Debugging, Profiling, Static Analysis ⭐ Architecture & Patterns: Clean Architecture, SOLID Principles, Design Patterns, Domain-Driven Design, Event-Driven Architecture ⭐ Security: Secure Coding, Authentication Systems, Encryption Basics, Data Protection ⭐ Other: Performance Optimization, Reverse Engineering, Code Refactoring, System Optimization, Network Programming, Data Structures, Algorithms, Logging, Monitoring A big part of my work is close to the system. I have experience working with Linux environments, including kernel-level understanding, low-level debugging, and performance tuning. I am comfortable solving problems not only in code, but also in system behavior, concurrency, and integration between components. I don’t just write code. I focus on stability, performance, and long-term maintainability. I often work on fixing complex issues, optimizing slow systems, or rebuilding parts that were not designed well from the beginning. Outside of work, I value a calm and stable life. I spend time with my family, and this helps me stay focused and consistent in my work. I prefer long-term cooperation where both sides trust each other and build something meaningful step by step. I can work independently, read existing codebases quickly, and deliver clean solutions without overcomplicating things. I am also comfortable joining ongoing projects and improving them step by step. If you need someone who understands both high-level architecture and low-level details, I can help. Thanks.

I’m a passionate Senior Game Developer / Gameplay Engineer with 6+ years of hands-on experience building AAA and AA titles across Unreal Engine, Unity, and C++. Over the years I’ve worked across the toughest parts of production, online multiplayer systems, replication at scale, performance optimization, and large gameplay feature ownership, while also contributing to emerging areas like blockchain integration and VR/AR simulation. At Magic Media, I contributed to an AAA first-person shooter (Revenge), where I focused on building and refining complex gameplay systems in Unreal and C++, implementing scalable ability-driven features using the Gameplay Ability System (GAS), and optimizing for performance in a production environment. I worked closely with designers and artists to ensure features were not only technically robust, but also met the gameplay quality bar expected from a AAA title. At Sovrun, I work as a Senior Unreal Engine Developer / Team Lead, contributing to an AA title while also supporting a blockchain-based Unity project using UniMUD. My core responsibilities are heavily multiplayer-focused matchmaking, networking, replication, and API handling implemented primarily in C++, alongside gameplay systems such as character abilities and inventory using a C++/Blueprint hybrid approach. In addition to engineering, I mentor junior developers, run code reviews, help unblock delivery, and guide architecture decisions so systems remain scalable, maintainable, and stable under iteration. I also contributed to an MMA game in UE5/C++, developing core combat gameplay (movement/attacks), a scalable combo framework, a fighting-style camera system, enemy AI, material-driven visual feedback (bruises/sweat tied to damage and exhaustion), and a full health/damage pipeline. Previously, at The VirtuLab, I engineered a highly realistic multiplayer VR rescue simulation, combining real-world terrain with Cesium, online connectivity with Epic Online Services, in-game voice with VIVOX, and custom VR interaction mechanics for immersive teamwork scenarios. This strengthened my experience building reliable networked features, real-time communication flows, and collaborating across multiple disciplines to ship simulation-grade experiences. Earlier in my career at Narsun Studios and MAIA Tech Systems, I built a broad portfolio across MOBA, PvE battle royale, and simulation projects, often bridging gameplay with backend systems and live-service needs. I also shipped an indie title, Sand Bullet, which I developed end-to-end and released on Steam, giving me a strong sense of product ownership and shipping discipline. Academically, I hold a Master’s in Big Data Science and Technology (Distinction, University of Bradford, UK) where I explored AI-driven interaction most notably controlling characters using EEG brain signals with deep learning in Unity and a Bachelor’s in Computer Science (FAST, Lahore), grounding my approach in robust engineering fundamentals and scalable system design. Technical highlights: Advanced C++/C# gameplay, AI, and network programming • Unreal Engine 4/5 and Unity development • Multiplayer systems: replication, dedicated server flows, matchmaking, online integrations • GAS and scalable gameplay architecture • Blockchain integration with Unity/UniMUD • VR/AR simulations and geospatial mapping (Cesium) • Cloud and data: AWS, GCP, PostgreSQL, Python • Version control: Perforce, Git I thrive in environments that push for a high quality bar and reward ownership. I combine strong gameplay engineering fundamentals with a delivery mindset building systems that are scalable, performant, and easy for teams to extend while also mentoring others and improving how teams ship. If you’re looking for someone who can own complex gameplay and multiplayer features and deliver them reliably, I’d love to connect.
