- FreelanceFreelance Hardware Design EngineerJuly 2023 - Today (2 years and 11 months)Berlin, GermanyAs a freelance hardware design engineer, I support startups, SMEs, and industrial companies in developing reliable and production-ready electronic systems. I provide end-to-end hardware development services, from concept definition and system architecture to schematic design, PCB layout, prototyping, bring-up, and validation.My expertise includes PCB design (Altium Designer), STM32-based embedded systems, analog and mixed-signal circuit design, and power electronics development. I design communication interfaces such as RS-232, RS-422, RS-485, CAN, and Ethernet, ensuring signal integrity and EMC-aware layouts suitable for industrial environments.I focus on robust, manufacturable, and cost-optimized designs, supporting clients during debugging, testing, and preparation for mass production. Whether you need a new product developed from scratch or improvements to an existing design, I can provide structured and reliable engineering support.
- Fotoniks Military Electro-Optics Industry Inc.Hardware Design EngineerDEFENSE AND MILITARYFebruary 2023 - November 2025 (2 years and 9 months)Ankara, TürkiyeWorked as a Hardware Design Engineer in a defense industry company developing military electro-optical systems and embedded electronic platforms. I was responsible for the full hardware development lifecycle including system architecture definition, schematic design, PCB layout, component selection, simulation, prototyping, hardware bring-up, and validation.Designed analog, digital, and mixed-signal circuits including power electronics subsystems, high-reliability power distribution architectures compliant with MIL-STD-1275E, and protection circuits for harsh electrical environments. Developed communication interfaces such as RS-232, RS-422, RS-485, and Industrial Ethernet, as well as Ethernet-based embedded communication systems for mission-critical applications.Implemented embedded hardware platforms based on STM32 microcontrollers, integrating high-speed interfaces, analog signal-conditioning circuits, and analog video (CVBS) transmission hardware. Performed PCB designs considering EMI/EMC compliance, signal integrity, power integrity, thermal performance, and manufacturability requirements for defense grade electronics.Collaborated closely with firmware, mechanical, and system engineering teams to deliver robust, field-ready embedded hardware solutions optimized for reliability, long-term operation, and demanding operational conditions.
- Fotoniks Military Electro-Optics Industry Inc.Intern Hardware Design EngineerDEFENSE AND MILITARYJuly 2022 - September 2022 (2 months)Ankara, TürkiyeCompleted a two-month internship within the hardware design team working on military electro-optical and embedded electronic systems. Supported engineers in schematic design, PCB layout reviews, component selection, and laboratory testing activities. Assisted in the development and validation of communication interfaces including RS-232, RS-422, RS-485, and Ethernet-based embedded systems, as well as STM32-based microcontroller platforms.Participated in testing and measurement of analog and mixed-signal circuits, power electronics subsystems, and analog video (CVBS) signal paths. Gained hands-on experience with EMI/EMC-aware PCB design practices, embedded hardware bring-up, and exposure to MIL-STD-1275E compliant power system design principles used in military vehicle electronic platforms. Worked closely with senior hardware engineers during debugging, verification, and documentation processes.
