Unmanned Aerial Systems (UAV)
RF Comms · FPV · LoRa WAN
From childhood to the present day, I've designed, built, and tested unmanned aerial systems. This lifelong passion has evolved into professional R&D at Wind & Wireless, where I explore the intersection of aviation, RF communications, and systems integration.
- Platform Development: Designed and deployed 9 UAV platforms (flying wing, EDF jet, multi-rotor) with analog/digital FPV and telemetry systems.
- Long-Range RF: Researched and tested long-range RF propagation and throughput using LoRa WAN, analog FPV (Runcam, FoxEER, TBS), and Walksnail digital systems.
- Full Lifecycle: Managed concept → CAD → fabrication → firmware (Betaflight/INAV) → field testing → community publishing.
Network Systems Engineering
GPON · Carrier WiFi · Global Leadership
Over a 10-year career at Calix, I progressed from on-site systems engineering to global field leadership. I designed, troubleshot, and deployed GPON, XGS-PON, and NG-PON networks across 13 countries — bridging the gap between customer experience and product engineering.
- Network Engineering: Debugged GPON, VoIP (SIP/H.248), IP Multicast, and Pseudowire networks using Wireshark, CentOS, and Linux-based OSS.
- Global Leadership: Trained and ramped new TAC engineers in Wroclaw, Poland and San Jose, Costa Rica — expanding our footprint into new continents and time zones.
- Community & Product: Implemented the "New Feature Request" program, bridging customer insights directly to engineering roadmaps. Co-Created "TAC TV" educational content that reduced repeat support tickets.
Mechatronic Systems Engineering
CAD · Fabrication · Maritime Ops
At Leidos, I designed and field-deployed electromechanical systems for submarine fiber optic cable operations. This work sits at the intersection of mechanical design, electronics, and operator experience — bridging shipboard systems, cable equipment, and human operators in rugged maritime environments.
The Challenge: Integrate custom communication systems onto cable-laying vessels, ensuring reliable operation in harsh ocean conditions.
- CAD Modeling: Designed mechanical components in SOLIDWORKS; fabricated prototypes using mill, lathe, and MIG welding.
- Integration: Connected shipboard systems, cable handling equipment, and operator interfaces via serial communications (RS-232/485).
- Field Deployment: Tested and validated systems in maritime operations — from concept to installed hardware.
