Hardware that ships.Code that runs.

I'm Luis - a welder by day in Orlando, and a self-taught hardware engineer the rest of the time. I design PCBs in KiCad, write firmware in C, and ship the software the devices report to. Out of a home lab.

Boards I designed and brought up.

Two custom KiCad PCBs at the top - the Air Sensor and a drone flight controller - drawn from schematic to bring-up by me. Below them, three finished products: the Mesh Motion Sensor, the Astra Air Sensor, and the Network Monitor. All ESP32-S3, all running today in a home lab.

Air Sensor - custom KiCad PCB

Two-layer board designed end to end: schematic, layout, fab, hand assembly, bring-up. ESP32-S3 next to a Sensirion SEN55 air-quality sensor; the whole thing runs off a single PoE 802.3af drop. The PCB itself - not yet in any finished product.

Mesh Motion Sensor

mmWave + Thread presence node

Distributed presence-sensing node using commercial mmWave radar modules on a Thread mesh. Sub-second occupancy detection across whole-floor coverage without PIR blind spots. Built from COTS dev boards; firmware and 3D-printed enclosures by me.

Thread mesh - no hub-and-spoke choke points
Radar instead of PIR, so no warm-body false negatives
Roadmap: integrate with AstraRMM for facility analytics

Astra Air Sensor

Finished product - PoE air quality monitor

The finished Air Sensor - Sensirion SEN55 inside a 3D-printed hex-vent enclosure, ESP32-S3, USB-C config, PoE/RJ45 uplink. Reports PM, VOC, CO₂, temperature, and humidity back to AstraRMM or any MQTT broker over a single drop.

The software the hardware reports to.

AstraRMM is a remote monitoring and management platform I helped build for MSP-style ops: agent deployment, endpoint telemetry, alerting, and a technician dashboard. TaskChrono is a SaaS tool for time tracking and reporting, shipped to a paying customer and still in active use. The devices on this page don't sit on a shelf; they report to platforms I had a hand in.

003ON THE GROUND

Production lead by day. Builder the rest of the time.

Production lead at Ravens Marine - running the welding floor and qualifying junior welders for production work. Evenings and weekends: contract field IT for Fanatic Node - Windows recovery, drive and RAM upgrades, BitLocker resets, admin-password recovery, PoE camera installs. The home lab in the background is where the PCBs above actually live.
