Hello! I have been working as a hardware developer for 7 years. Expert in PCB Design up to 6 layers, qualified in electronics design with experience in the development of electronics devices. Experience in( Power electronics, SMPS, Led Drivers, power control) Passionate about designing an electronics system that involves analog and digital components with power electronics. I will take the responsibility to find a solution for your complex circuit PCB is my passion and my Hoppy. WHY CHOOSE ME OVER OTHERS? PCB design and Electronics is my passion so I will do my best to make the design that means: Designing sequence: 1. Electrical calculation for your design 2. Simulation for every Block (circuit) 3. Make the schemes 4. Make the prototype in Egypt (prototype1) to test the schemes 5. After passing the test making the high-quality prototype (prototype2) and order it for you 6. Generate BOM, Gerber, ETC Payment system : You will make 3 milestones: 1- the minimum fees and release them after winning the bid 2- after receiving video prove work of prototype 1 3- after receiving the final prototype 2 notices : 1. Your modification is welcomed 3. I will help you with your whole project 4. I will be honest with you if the project can be done or not 5. I will reverse the design of your competitors ✔️ I'm an Expert in PCB Design UP to 6 layers with: 1. Kicad 2. EsayEDA 3. Altium 4. Eagle 5. proteus ✔️ I have experience in: 1. Hardware design: 2. Analog Circuits 3. Digital Circuits 4. Multilayers PCB layout ✔️ Circuit Analysis: 1. microstrip Antenna simulation (HFSS) 2. reverse engineering 3. theoretical Analysis ✔️ Simulation: 1. Multisim 2. circuit wizard 3. proteus ✅ Others Experience: ✅ lecturer, I have taught several courses: ✅ writing : 1. Technical articles &blogs about Electronics ✔️ I had implemented lots of projects (All of below tested and worked well): 1. ESP8622 as a HUB for other ESP modules 2. Blynk APP 3. timers for transient and long time 4. voltage protection from high voltage 5. mobile detector 6. sensors (LDR motion detector -magnetic Switch-PIR) 7. SMPS (19v modification - step-up & step down - battery charger) 8. phase voltage stabilizers full designed for high volt 220v+ 9. sheet metal design for electronics enclose 10. high gain microstrip antenna array (patch antenna) in HFSS 11. PICMCU 12. CST & HFSS simulation I will cooperate with you to do my best in your project ?

Simple PCB Design for PCBway • $200 USD
Ahmed has a lot of talents from PCB design to 3d rendering of my enclosure to fit the PCB and other electronics. Really impressive work and attention to detail. He worked hard to get the project requirements met on time even as they evolved during the project. I recommend hiring him for your project.

Switchable constant current circuit (7 -> 14ma) against changing load (20 -> 2100 Ohms) • £120 GBP
I enjoyed working with Ahmed - he is very knowledgable and was also patient talking me through the different designs to meet the target. He was very persistent and made sure his designs did exactly what I wanted in both simulation and practical application. He sent me videos with explanations for each part, which was very helpful. I would definitely recommend his work, and will use him again in the future.
