Hire the Best OpenWrt Specialists

Multi-discipline system engineer with more that 25 years of experience on Linux/Unix, networking, high performance computing and high availability / high reliability systems. Interested in: - Building large scale high-loaded web platforms running in heterogeneous environment - High performance networking with SDN/NFV - Embedded development and wireless technologies, mostly small-sized and power-efficient (IoT, etc).

I'm a DevOps Engineer with experience as a network engineer. I've worked with the following providers AWS, GCP, Digital Ocean, Hetzner. I'm familiar with Docker and Kubernetes, and for automation I mainly use Ansible and Bash. My main OS that I've worked with on servers is Linux (Ubuntu, Debian, RHEL). I can help with most networking tasks either on cloud (VPCs, subnets, routing) or on-premises. Basic networking tools such as iptables, nftables, tc, and of course ip route. I'm familiar with VPN protocols and have used it as a server and client Such protocols are: Wireguard, OpenVPN, IPSEC/IKEv2 (StrongSwan/Libreswan), SoftEther.

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 build production-grade real-time systems in Rust where correctness, latency, and throughput numbers decide whether the thing works. My specialty is GPU-accelerated visualization and processing of high-frequency sensor data: the case where a hardware, science, or robotics team has a working product but the data outruns their CPU tooling and the display stutters, drops samples, or cannot run the signal processing in time. What I do - GPU real-time visualization in Rust/wgpu: hundreds of channels at kHz rates, with signal-processing compute (FFT, filtering, fusion) running inside the same frame, native and in-browser via WebGPU/WASM - Real-time systems with hard latency guarantees: lock-free ring buffers, bounded end-to-end latency, no dropped samples - High-throughput data pipelines and streaming infrastructure: resilient connection pooling, crash-recoverable and exactly-once ingestion, horizontal scaling with automatic failover Async runtime internals and performance: diagnosing and fixing tail-latency, executor starvation, and throughput walls in production Rust - C/C++/Java/Python to Rust migration: FFI boundaries, unsafe, zero-copy, the parts that do not auto-port Recent work - A real-time multi-mode flight-instrument (EFIS) rendering engine in Rust/WASM/WebGPU: synthetic 60Hz state, quaternion attitude, reverse-Z depth, procedural geometry, targeting tablet and AR glass at 60–120 FPS - A production-grade Solana indexer handling 40+ TPS with zero event drops: WAL-based crash recovery, gap detection with RPC fallback, auto-healing architecture, designed for 5,000+ TPS mainnet workloads Core competencies: Rust · wgpu / WebGPU / WASM · tokio · tonic · axum · TimescaleDB / PostgreSQL · real-time GPU rendering · high-frequency sensor pipelines · async runtime internals · low-latency & lock-free systems · zero-copy FFI · distributed data architectures Technical Writing. I also write about deep technical topics: Rust internals, distributed-systems failure modes, and the parts of infrastructure that break in production. When to hire me You have a domain-first product: in instrumentation, hardware, infrastructure(GPU/CPU cluster) observability, robotics, sensing, or finance, blocked by a hard systems problem outside your team's discipline, where getting the abstractions, the latency, and the correctness right matters more than shipping fast. That is the work I am built for.
