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. 🙂

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.
