We help ISPs, OEMs, and product teams architect, debug, and ship OpenWrt-based networking platforms — including multi-vendor 4G/5G modem integration and CPE firmware systems.
Small senior team • Platform-level engineering • Remote-first consulting
Flexible engineering support models designed for real-world OpenWrt and embedded networking challenges.
We work deep in the OpenWrt and embedded networking stack, focusing on problems that affect real deployments.
Hands-on help when your OpenWrt or networking project is blocked, unstable, or behind schedule. We jump in, diagnose fast, and unblock delivery.
Reliable, recurring engineering support for teams that need continuous development, maintenance, and system hardening — without hiring full-time.
Designed and implemented a modular OpenWrt-based 5G CPE firmware platform supporting multiple cellular modem vendors. Built boot-time modem detection, dynamic QMI/MBIM configuration, 5G SA/NSA mode detection, signal normalization, and LuCI-integrated cellular diagnostics.
Validated across multiple modem variants with consistent 500–700 Mbps downlink performance in NSA deployments.
Customized OpenWrt firmware and board support layers for a networking gateway device. Work included device tree updates, MAC provisioning, Wi-Fi initialization logic, QMI stabilization, and production release hardening.
Joined an in-progress OpenWrt-based ISP management system to unblock release delays and improve reliability. Focused on client visibility, configuration safety, backend coordination, and production issue resolution.
Provided short-term embedded engineering support to resolve WAN and Wi-Fi instability, configuration race conditions, and system observability issues prior to production release.
GNSOFTLAB is a small team of senior embedded engineers specializing in OpenWrt-based networking platforms, 4G/5G modem integration, and CPE firmware architecture.
We work directly with OEMs, ISPs, and product teams to design, stabilize, and extend embedded networking systems — from boot-level modem detection and network stack integration to LuCI-based management interfaces and production release hardening.
Our focus is platform-level engineering: reducing vendor lock-in, supporting multi-hardware deployments, and building firmware systems that scale beyond a single device SKU.
We operate lean, engineer-to-engineer, without agency overhead — providing deep technical support where it matters most.
Tell us what you’re working on and where you’re stuck. We’ll review and respond directly — engineer to engineer.
