I help startups and companies develop reliable, production-ready electronic products, from architecture and schematic design to PCB layout, prototyping, and manufacturing support. My experience includes high-speed multilayer PCB design, mixed-signal systems, power electronics, BMS development, and embedded hardware for industrial and IoT applications. I have worked with interfaces such as DDR, Gigabit Ethernet, USB, and M.2 while applying signal integrity, power integrity, EMI, and manufacturability considerations throughout the design process. I focus on clear communication, manufacturable designs, and reducing prototype iterations to help clients move faster toward successful products.

I have good experience of three years of teaching Circuit Theory and Basic electronic Devices such as Diode, MOSFET, BJT, Op-Amp, Differential pair, Current Mirror, and Oscillator topics such as Harmonic oscillator and multivibrator. Also related topics such that Feedback, frequency response, and noise analysis. I have good experience in cad tools such that Altium, protus, Multisim, OR CAD, and LT spice. I graduated from the department of communication and electronics and Mastered analog and Digital (Mixed) IC circuits and Master Cadence Virtuoso software and VLSI Layout. I also Work on Matlab, Simulink, and Matlab GUI. I design a high-speed current steering Digital to analog converter in cadence virtuoso and its related circuit like Decoder, Flip Flops, and Applying Dynamic Element Matching to our DAC by using a Logarithmic shifter and 16 Bits linear feedback shift register and dealing with designing a custom Digital logic gates and Layout for each one. Also, a two-stage biopotential amplifier for ECG, EMG, and EMG applications is performed in 130 nm technology under Cadence Virtuoso. all of my previous give me a good experience

PROFILE Formerly Ass. Prof. in the Military Technical College. • Microwave and RF system design engineer • Analog and digital circuit design engineer • CAD/CAM engineer for PCB design and manufacture by CNC machines • Microwave and RF circuit design engineer • Microwave receiver expert. • University lecturer (Microwaves, Receivers, Logic Circuits, Electromagnetic Fields and Computer Networks). KEY ACHIEVEMENTS • Design, implementation, and testing of hundreds of RF and MW filters. • Design, implementation, and testing of wide-band printed dipole antennas (2009- 2013). • Author of 24 papers published in different international conferences and academic magazines, most of which are single-author papers. • Design, implementation, and measurement of a complete DRFM. • Proposing a new method for digital frequency translation using DRFM. It was published in a paper and successfully implemented. • Supervision of 4 MSc. Theses and 1 Ph.D. Thesis. • Reviewing 5 Msc. Theses and 5 papers. • Leading more than 30 graduation projects. • Hundreds of RF and Microwave PCB's have been designed by me and prototyped under my direct supervision. Most of those circuits were Microstrip circuits. Some coplanar waveguide circuits have also been designed and implemented. • FR4 was the main substrate in most designs. Different professional substrates (of Rogers and Arlon products) have been used in my designs with relative permittivity ranging between 2 and 10.5 and dielectric height between 0.2 and 2.6 [mm]. CAPABILITIES I can design RF systems and circuits, RF antennas and electronic circuits, give you full design and prototyping documentation (including design description, design equations and calculations, simulation results, schematic and layout drawings, Gerber files, Excellon files and BOM files, test procedures and test recommendations) and give full technical assistance to you in prototype building and testing. No prototype building No software coding

Are you looking for a freelancer creating accurate and reliable 🔴 Circuits schematics, layouts, and simulations as well as 3D CAD models 🔴? As a mechatronic engineer, I have an electrical and mechanical engineering background. I am introducing myself and my services as a freelancer in the field of electronic circuits and PCB design. Being a mechatronic engineer helps me to integrate both electrical and mechanical considerations into my designs, and that's what sets me apart from other designers. My expertise lies in using: • Autodesk Eagle • Altium designer • EasyEDA • KiCad • Proteus To generate accurate and reliable: • Schematics • PCB layout design • 3D models And I will provide you with: • Detailed PDF files • Images • DXF files • Bill of Materials (BOM) That clearly illustrates the design and its components, and this will not only help you to understand the design better but also allow for quick and efficient manufacturing processes. I can help you design your ⚫ 3D model enclosure ⚫ for your PCB or consider this aspect while designing the PCB itself. This results in a more integrated and optimized solution that meets both your electrical and mechanical requirements. As a new freelancer on Upwork, I am eager to take on any job at the 🔴 most reasonable cost 🔴 to grow on this platform and receive valuable feedback. I am committed to building long-term relationships with my clients by prioritizing clear communication, timely delivery, and customer satisfaction. I am open to feedback and willing to make adjustments to ensure complete satisfaction with my work. I am eager to establish a lasting partnership.
