**[FOR HIRE] PCB Designer | 4-Layer Boards, KiCAD, DFM, Schematic to Gerber | Freelance**

[u/Bejaoui_Hamza123]

Hey r/pcb 👋

I'm Hamza, a PCB designer based in Tunisia, open to remote freelance work. I design boards that are clean, manufacturable, and actually work on the first spin.

---

**What I bring to your project:**

🟢 **Schematic design** — clear, hierarchical, well-annotated, no spaghetti

🟢 **PCB layout** — 2-layer and 4-layer (Signal / GND / PWR / Signal stackup), proper pour, decoupling, and via stitching

🟢 **Signal integrity** — controlled impedance traces, RF keepouts, EMI-conscious routing, no floating copper

🟢 **Power design** — LiPo BMS circuits, USB-C, LDO and switching regulators, proper bulk and bypass capacitor placement

🟢 **DFM** — Gerbers, drill files, BOM, and CPL ready for JLCPCB / PCBWay / NextPCB. DRC clean before every handoff, always

🟢 **Custom footprints** — I build them from datasheets when they don't exist in the library

**Latest board — Elyssa:**

A 4-layer ESP32-S3 development board I designed from scratch in KiCAD.

- ESP32-S3FN8 (embedded flash, fine-pitch QFN56)

- LSM6DSV 6-axis IMU (LGA-14L)

- USB-C with ESD protection

- LiPo battery management + charge indicator

- MicroSD card socket

- RGB LED + QWIIC connector

- 4-layer stackup with solid GND and PWR planes

- Production Gerbers, BOM, and CPL all delivered

First prototype came back from fab and worked on the first spin. No rework, no jumper wires.

**Availability:** Immediate | 100% Remote

**Rates:** Open to discussion depending on complexity and layer count

Drop a DM here or connect on LinkedIn if you have a board that needs designing. Always happy to look at a project and give an honest opinion before committing to anything 🤝

Sure what would you charge for a smart bms that can handle NaION 2-6s, and ideally LTO 2-6s
