Senior Embedded Linux & Infrastructure Consultant

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.
