About this Gig
Your last PCB came back from the manufacturer with wrong footprints, shorted traces, or a microcontroller that won't boot. You paid someone for schematic de-sign and got a file full of unlabeled parts and no explanation. You've lost money, lost weeks, and you're still without a working board.
This gig fixes that.
I design schematic diagrams and PCB layouts for ESP32 circuit de-sign, STM32 circuit de-sign, and Arduino-based electronic circuit projects that work on the first manufacturing run. Every schematic de-sign goes through electrical rule checking. Every PCB layout goes through design rule checking before it reaches you.
I work daily on Altium Designer, KiCad, and Eagle, covering schematic design, PCB layout, circuit design, esp32 circuit, stm32, embedded PCB, IoT PCB, power supply circuit, battery charging circuit, multilayer PCB, and PCB prototype de-sign. Every project includes Gerber files, BOM, and a 3D board preview so you can visualize the finished PCB layout before it's manufactured.
My Services:
- Professional PCB De-sign
- Accurate PCB Schematic
- Optimized PCB Layout
- Complete Circuit De-sign
- ESP32 PCB & STM32 PCB Development
- Arduino PCB De-sign

FAQ
I only have a hand-drawn idea or a rough sketch, no formal schematic. Can you still design my PCB?
Yes. Many buyers come to me with a napkin sketch, a voice note description, or a reference product they want replicated. I convert that idea into a complete schematic design with correct component values, then move into PCB layout. You don't need any technical documentation prepared beforehand.
My previous freelancer disappeared after delivering broken files. How do I know you won't do the same?
I stay available until your circuit design actually works, not just until files are delivered. If your PCB layout comes back from manufacturing with an issue traced to the design, I fix it. I don't close a project while a buyer still has an open concern about their schematic design or PCB layout.
Can you fix or complete a schematic design or PCB layout someone else started?
Yes. I regularly take over unfinished or broken circuit design projects, missing footprints, incorrect wiring, unrouted PCB layout, or a schematic design that doesn't match the actual component datasheets. Send the existing files and I'll assess what's usable before any work begins.
What information do you need from me before starting my ESP32 or STM32 circuit design?
Just your project goal, any specific components you already own or want included, power source (battery or mains), and enclosure size if space is limited. If you're unsure of any of this, tell me the function you want the board to perform and I'll recommend the right components.
Will my PCB layout work with JLCPCB, PCBWay, or my local manufacturer?
Yes. All PCB layout and gerber files are generated to standard RS-274X format accepted by every major manufacturer, including JLCPCB, PCBWay, Seeed Fusion, and local fabrication houses. There is no manufacturer-specific rework needed.
My board needs to run on battery. Can you handle power management in the circuit design?
Yes. Battery charging circuit design, low-power sleep modes, and voltage regulation are built into the schematic design and PCB layout when your project requires battery operation. This is common with ESP32 circuit design and STM32 circuit design projects for portable or wearable devices.
I need this for a real product, not a hobby project. Can you sign an NDA?
Yes. I work with startups and product teams regularly and have no issue signing an NDA before reviewing your circuit design details. Your schematic design, PCB layout, and project information stay confidential.
What if my microcontroller isn't ESP32 or STM32?
I also handle circuit design and PCB layout for Arduino, ESP8266, PIC, ATmega, and other common microcontrollers. If your project uses a less common chip, message me the part number and I'll confirm compatibility with your schematic design before you order.
How do I know the PCB layout won't have interference or connectivity issues once built?
Every PCB layout goes through routing checks focused on signal integrity, especially around wireless modules, crystal oscillators, and power traces, which are the most common causes of ESP32 circuit design and STM32 circuit design boards failing to connect or boot after manufacturing.
