Work Experience

Embedded Software & FPGA Engineer

2019 - 2023
Raith GmbH
  • Developed an embedded device from scratch as ZYNQ SoM communicates with Bare Metal and Yocto-based Embedded Linux.
  • Created a DMA Transfer mechanism from ZYNQ to Embedded Linux to C# GUI on PC without data loss.
  • Designed and developed own Chip2Chip communication protocol between ZYNQ and Spartan FPGAs.
  • Developed and used numerous protocols on FPGA and Embedded Linux. Some were PCI-e, SPI, I²C, 1-Wire, SPF+, JTAG, UART.

Embedded Software & FPGA Engineer

2016 - 2017
Era Instruments
  • Designed and developed the software and FPGA portions of the two systems below on Linux.
  • Assisted in the creation of the Signal Intelligence System designed to collect ELINT and COMINT signals.
  • Expanded the Direction Finding System: Added DMA transfer capability over PCI-e (3.0 x8) bus. Updated the entire FPGA portion of the project according to DMA transfer over PCI-e. Modified also the Linux Device Drivers.
  • Devised communication protocols with PCI-e (3.0 x8), 10Gb, 1Gb, 100Mb, Ethernet, and UART. Used FPGA-related products such as Verilog, VHDL, DMA Transfer, JESD204, TCL, and Microblaze Linux.

Embedded Software Engineer

2012 - 2016
  • Developed various military projects about COMINT and ELINT (Signal Intelligence).
  • Designed and implemented the National Emitter Database (SQL Server 2012) with 40 relational tables.
  • Utilized communication protocols such as PCIe, 1Gb and 100Mb Ethernet, and UART. Recorded and replayed data to and from raid systems, Linux device drivers, and multithreading with C#, C++, and C.

Senior Software Developer

2009 - 2012
Turkey Finans
  • Developed various loan and credit software using n-tier architecture.
  • Implemented projects with approximately 90 software developers.
  • Served as project manager and used TFS as source control.
Technologies: C#, .NET, SQL Server 2008, Windows Communication Foundation (WCF), VB, Software Design Patterns, Object-oriented Programming (OOP), Best Practices

Motor Control (Nanometer Scale)
A Xilinx System-on-Module (SoM) controls the device I developed entirely from scratch. My responsibilities included implementing a C++ application on Yocto-based Embedded Linux, a C application on Bare Metal, and Verilog designs on Vivado. Our design incorporates a ZYNQ FPGA as the main FPGA and Spartan-7 FPGAs as sub-FPGAs.

Additionally, I created my own communication system as an alternative to Xilinx's Chip2Chip IP Core. Most of the system operates in real-time at a frequency of 50 kHz. It's worth noting that our device operates at the nanometer/Angstrom scale, highlighting its exceptional precision.
