Description

I'm Sinai, a Senior Embedded Systems Engineer with 8+ years of experience building real hardware for demanding environments — from CubeSats in orbit to autonomous drones on water.

I specialize in low-level C/C++ development, sensor fusion, real-time systems, and wireless communication (LoRaWAN, CAN, BLE, NB-IoT). I'm comfortable going from bare-metal firmware all the way to PCB design and system architecture.

Past work includes:

• Chief Electronics Engineer on a TU Delft CubeSat (Da Vinci Satellite)

• Autonomous water drone navigation system (GPS/compass/radar fusion)

• Industrial LoRaWAN satellite data transmission (Echostar/AWS)

• Military-grade RF signal scanner (FPGA + SDR, TNO/NATO)

I run CodeXSinai, an independent engineering company based in Rotterdam. I work remotely across Europe and the Middle East, and I take on projects where precision and reliability actually matter.

If you need someone who can own a problem end-to-end — hardware, firmware, and integration — let's talk.

Cargosys — Satellite LoRaWAN Vibration Telemetry System
Embedded Systems Engineer · Rotterdam, Netherlands
INTERNET OF THINGS (IOT)
January 2026 - Today (5 months)
Rotterdam, Netherlands
Built an end-to-end wireless vibration data transmission system for an industrial client, using satellite LoRaWAN as the communication backbone — enabling data collection from remote locations without terrestrial network coverage.

Developed the full pipeline: firmware on an STM32-based Nucleo board communicating with an Echostar EM2050 satellite module, through to cloud ingestion via AWS SQS. Both uplink and downlink paths validated over live satellite link.

FutureBit — Apollo II Platform
Embedded Systems Engineer · Remote (New York, USA)
TECH
January 2026 - Today (5 months)
New York, NY, USA
Owned the power management architecture of the Apollo II — a high-performance computing platform. Redesigned the power bus, upgraded the FPGA subsystem, and developed the embedded control software from bare-metal up.

Worked across the full stack: VHDL for FPGA logic, C/C++ for ARM firmware, and Go for higher-level system control — all communicating over PMBus.

Bosch — Fire Detection & Building Safety Systems (4Evac)
Embedded Systems Engineer · R&D
TECH
March 2024 - December 2025 (1 year and 9 months)
Berkel en Rodenrijs, Netherlands
Part of the Bosch R&D team building the next generation of professional fire detection and evacuation systems. Owned the embedded network layer — designing and implementing real-time audio, video, and data communication across complex building infrastructures.

Integrated Audio/Video Bridging (AVB) with MQTT to enable reliable, low-latency communication in ad-hoc network topologies where traditional infrastructure isn't guaranteed. Systems had to work flawlessly — lives depend on it.

Drove end-to-end development: from architecture and simulation to hardware bring-up, sensor-actuator integration, and field testing — across both bare-metal and FreeRTOS environments on NXP RT-series processors.
