Hire the Best OpenVPN Specialists
in India

Senior embedded firmware engineer with 5+ years shipping production networking devices — 10+ product lines, 2000+ units in the field. I take routers, switches, and access points from prototype to production, and I'm now weaving edge AI into the firmware, mesh, and connectivity stacks I've built for years. What I do best: • OpenWRT firmware development (x86, MediaTek, Qualcomm, Broadcom) • 5G/4G bonding routers — inventor on a filed patent for MPTCP scheduling (Indian Patent App. No. 202541092429) • Self-healing mesh networks (BATMAN-adv, 802.11s) with fast roaming • Cloud-managed captive portals (CoovaChilli), Multi-VLAN isolation for hospitality & POS • MQTT telemetry, OTA/FOTA upgrades, remote device management • Edge AI & agentic workflows — AI-enabled domain filtering, custom automation agents Recent wins: • Led the technical turnaround of a US client's stalled product line (CleanRouter, Arizona) as a remote contractor — resolved critical legacy bugs, re-architected mesh communication logic, and took products to shipment-ready • Architected a 5G cellular bonding router with integrated NVR for professional livestreaming • Built enterprise cloud-controlled switches with per-VLAN captive portals and Chromecast isolation for hotels Remote-first, working worldwide. If you need firmware that survives real-world deployments — or AI woven into your network stack — let's talk.
