Want to actually make money from your game and turn your idea into something that brings real value, not just another app that gets ignored? That’s exactly what this is about! Games built here consistently reach 100K+ to 500K+ downloads and generate real revenue for clients, because the focus is not just on development, but on gameplay, retention, and monetization from day one. Most games technically “work” but fail at gameplay, player experience, and long-term engagement. The focus here is simple, not just mobile game development or video game development, but building a game that people enjoy playing and keep coming back to. Everything starts with how the game feels. Before scaling, the core gameplay is shaped - how players interact with the game - how levels are structured - how progression works - and why someone would continue playing after the first session Once that is clear, the game is built in Unity with a strong balance between game design and game development, making sure mechanics, UI/UX, animation, and overall flow work together as one system. From there, the focus shifts to what actually drives growth - performance across Android and iOS devices - smooth gameplay and responsiveness - and systems like rewards, leaderboards, and monetization that support long-term engagement This naturally includes working with Unity, C#, mobile game systems, gameplay mechanics, 2D and 3D environments, animation, UI/UX, and optimization, but always with the goal of building a complete product, not just features. Because in the end - a successful game is not just about launching it’s about - players staying - coming back - and spending time (and money) inside the game If you want to build a game that actually performs - message me, and let’s turn your idea into a real money making machine!

I am a Senior Embedded Linux Programmer and IT/Infrastructure Consultant with nearly 40 years of overall development experience. I specialize in getting tough hardware and networking projects off the ground—or rescuing existing projects that have hit a wall. Because my background spans the entire stack—from bare-metal custom Linux kernels to advanced enterprise server configurations—I can troubleshoot and build systems that most single-discipline developers cannot. Here are my core areas of expertise: • Embedded Linux & BSP: Custom firmware, kernel drivers, and deep optimization for SoC boards (Raspberry Pi, Orange Pi, NanoPi, etc.). I have extensive experience with Buildroot, Yocto, MAC-PHY communication, and precision timekeeping (PTPv2/IEEE 1588v2). • Networking & Telecom: 7+ years building 4G/LTE protocols (MAC-level, EPC, QoS). I regularly handle BGP routing issues, VPN implementations (IPsec/StrongSwan), and complex traffic convergence. • Edge AI & Computer Vision: Building optimized pipelines for video surveillance, real-time object tracking, and deploying AI models directly on edge devices. • Infrastructure & Email Systems: Advanced Postfix customization. I routinely design secure email obfuscation workflows, generate robust SPF/DKIM records for domains, and manage complex DevOps tasks like cloud migrations and remote work infrastructure. Zabbix and Grafana infrastructure monitoring, custom agents, alerting and visualization. Past Successes: • Led the full-lifecycle development of the MaxBridge 4G solution, successfully deployed across four countries. • Core BSP Engineer on the highly successful Carsifi project. • Rework old systems with new core elements, incorporating existing hardware protocols. I don't just write code; I solve system-wide problems. If you need someone who understands exactly how your hardware talks to your network, send me a message and let's discuss your project.
