I'm Selim Can ÖVÜR — an embedded systems and AI-focused mechatronics engineer with hands-on experience in building real-world, production-level IoT systems. I focus on end-to-end solutions, from low-level device control to backend integration and AI system optimization.

• Real-time communication protocols (UDP, HTTP)
• Secure device communication with encryption and certificate-based authentication (mbedTLS, AES256, TLS)
• Memory optimization and partitioning for low-cost embedded devices
• OTA (over-the-air) update mechanisms and device versioning
• Backend integration using Flask APIs and custom queuing/database systems
• AI integration with TTS, STT, LLM fine-tuning, CUDA, and G-Cloud services
• Scalability Solutions For Real-Time Database-Transactions (RabbitMQ, Reddis Cache Microservice Applications)

I have hands-on experience in PCB design and electronics prototyping, covering the complete development cycle from schematic design to board manufacturing and debugging.

🛠 - Schematic & PCB Design: Skilled in KiCad, capable of designing PCBs with both analog and digital components.

🧰 - Hardware Debugging: Skilled in using oscilloscopes, logic analyzers, and multimeters for signal tracing and fault isolation.

🔌 - Power & Signal Integrity: Designed custom power regulation circuits, including buck/boost converters and filtering stages.

🔧 - Prototyping & Assembly: Experienced with SMD soldering, PCB rework, and rapid prototyping for embedded products.

🖨️ - Fabrication Ready Designs: Delivered production-ready Gerber files and BOMs for board manufacturing services.

📐 - Sensor Integration: Integrated various analog/digital sensors (load cells, EMG electrodes, IMUs, temperature sensors) into embedded systems.

These experiences support my ability to deliver complete embedded solutions from hardware design to fully functioning firmware.

• TM1650 Display Driver: A custom driver written in C++ to control multiple TM1650-based 4-digit 7-segment display modules using a shared clock line

• Embedded Firmware:
  Developed the complete firmware stack for an IoT-based smart toy, designed for children. The system included:

  • Audio playback over I2S using real time processed sound files
  • OTA updates, version control, and certificate-based device authentication
  • Dynamic memory management and low-level encryption (AES, TLS)
  • HTTP and UDP-based cloud communication
  • Partition Scheme and Embedded File System Management
  • Safety-critical firmware handling and robust fail-safes
  • Worked closely on sound engineering aspects including codec integration and timing-sensitive playback using limited resources.
  • Captured 24-bit stereo audio from microphone over I2S, performed signal processing and format conversion (downsample to 16-bit mono) on the ESP32.
  • Sent optimized audio streams to a server which then sent to cloud-based speech recognition API.
  • This required custom buffer management, lightweight DSP techniques, and low-latency transport to enable efficient voice command recognition in an embedded environment.

• Software Development:

• Developed a javascript based IOT server API, handled communication over HTTP and UDP, managed device authentication and mutual certification.

• Databases:

• MySQL

• HX711 Multi-Sensor Calibration Tool:
  Python tool to calibrate up to 10 load cells, store calibration data in JSON format, and send it to a backend server via POST requests.

I enjoy building efficient and secure mechatronics solutions — from protocol design to cloud integration and AI systems.
