Embedded Systems Engineer | Space Systems & RF | SDR | CubeSat | Ground Stations

I design, build, and test hardware–software integrated systems with a strong focus on
embedded electronics, RF communication, and space-related technologies.

My work spans from bare-metal microcontrollers to SDR-based ground stations, combining low-level engineering discipline with system-level thinking.

• 🛰 CubeSat & Space Systems

  • CubeSat subsystem design (OBC, RF, power, payload concepts)
  • Ground Station as a Service (GSaaS) architectures
  • Full-duplex VHF/UHF RF chains and SDR pipelines

• 📡 RF & SDR

  • SDR-based receivers/transmitters (AD936x-class architectures)
  • Signal processing, modulation & demodulation experiments
  • Antenna concepts, RF front-end design, and link analysis

• 🔧 Embedded Systems

  • STM32, RISC-V based systems
  • Sensor integration, low-power designs
  • Bare-metal and RTOS-oriented development

• 🛠 Systems & Infrastructure

  • Linux-based embedded environments
  • DevOps & containerized toolchains for engineering workflows
  • Kubernetes fundamentals (CKA-focused hands-on labs)

• Hardware first, software disciplined
• Datasheets > assumptions
• Measurable, testable, repeatable systems
• Designed for failure, debugged for reality

I enjoy working at the intersection of: electronics · RF · software · space systems

• STM32 • FPGA • RISC-V
• SPI • I²C • UART • CAN
• Power electronics & low-power design
• Sensors & custom boards

• SDR (GNU Radio, custom pipelines)
• VHF / UHF
• Digital & analog modulation concepts
• Antenna fundamentals

• C / C++ • Python
• Linux (embedded & server)
• Docker
• Git • CI-oriented workflows

• 🔹 CubeSat RF Experiments
• 🔹 SDR Ground Station Modules
• 🔹 Embedded Sensor Nodes
• 🔹 GSaaS Architecture Drafts
• 🔹 Hands-on Labs & Notes

(Repositories focus on real engineering problems, not toy examples.)

It’s about making it work again, and again, under constraints.”
