🚀 I help startups, engineers, and businesses turn hardware ideas into reliable, cost-effective, and manufacturing-ready electronic products. With a background in electronics engineering and 10 years of experience in electronics manufacturing and PCBA/SMT-related processes, I combine PCB design expertise with practical knowledge of manufacturing and assembly requirements. My goal is to deliver reliable electronic designs that meet technical requirements, optimize costs, and simplify the transition from design to production. 🛠️ MY KEY SERVICES ✅ Schematic Design – Developing electronic circuits from client requirements and technical specifications. ✅ PCB Layout Design – Single-layer, double-layer, and multilayer PCB design with careful component placement, routing, grounding, and manufacturability. ✅ Existing PCB Modification – Component substitutions, footprint updates, schematic modifications, routing changes, and design improvements. ✅ Hardware Design – Component selection, circuit development, power management, and embedded hardware design. ✅ Multilayer & High-Speed PCB Design – Controlled impedance, differential pairs, signal integrity, power integrity, and high-speed interfaces. ✅ Power Electronics – Buck/boost converters, LDOs, power distribution, battery-powered circuits, and protection circuitry. ✅ RF & Wireless Hardware – PCB design for wireless modules, RF-related applications, and antenna integration. ✅ IoT & Embedded Hardware – Custom electronics for ESP32, ESP8266, STM32, Nordic nRF, and other microcontroller-based systems. ✅ Design Review & Optimization – Identifying potential design issues and improving reliability, manufacturability, and cost efficiency. ✅ Manufacturing Support – Preparing production files and assisting with PCB fabrication, component sourcing, and PCBA ordering. 💻 PCB DESIGN SOFTWARE I work with the following PCB design tools to support different project requirements: 🔹 Altium Designer 🔹 KiCad 🔹 EasyEDA 🔹 OrCAD X I can develop a new design from scratch or modify an existing project while maintaining organized, editable design files. ⚡ TECHNICAL EXPERTISE My experience covers a variety of electronic hardware applications, including: 🔹 ESP32 and ESP8266 development boards 🔹 STM32 and custom microcontroller boards 🔹 IoT controllers and sensor interfaces 🔹 Battery-powered electronic products 🔹 DC-DC converters and power management 🔹 Motor drivers, relay boards, and control circuits 🔹 USB 2.0 / USB 3.0 hardware 🔹 RF and wireless communication hardware 🔹 High-speed digital interfaces 🔹 Analog and low-noise circuits 🔹 Multilayer and high-density PCB layouts 🔹 Custom-shaped PCBs and enclosure-constrained designs 🔌 Communication interfaces: I2C, SPI, UART, USB, CAN, and RS-485. 🏭 MANUFACTURING & PRODUCTION EXPERIENCE My 10 years of electronics manufacturing and PCBA/SMT-related experience help me approach PCB design with practical production considerations in mind. I focus on: ✔️ Design for Manufacturability (DFM) and Design for Assembly (DFA) ✔️ Component availability and alternative part selection ✔️ PCB fabrication and assembly requirements ✔️ BOM cost optimization ✔️ Electrical and mechanical design considerations ✔️ Reliable manufacturing handoff 🎯 I aim to minimize avoidable manufacturing issues, reduce unnecessary redesigns, and deliver practical designs ready for production. 📦 WHAT YOU WILL RECEIVE Depending on your project requirements, deliverables may include: ☑️ Complete schematic source files ☑️ Editable PCB design files ☑️ Gerber and drill files ☑️ Bill of Materials (BOM) ☑️ Pick-and-Place / CPL files ☑️ Assembly drawings and fabrication documentation ☑️ 3D PCB models and STEP files, where supported ☑️ Design review notes and manufacturing recommendations 🏗️ I can also assist with PCB fabrication and assembly through JLCPCB and other suitable manufacturers. 🤝 WHY WORK WITH ME? I combine electronic design skills with practical knowledge of manufacturing and assembly processes. This allows me to consider not only how a circuit works, but also how the PCB will be fabricated, assembled, and integrated into the final product. I value clear communication, careful engineering decisions, organized deliverables, and solutions that balance performance, reliability, and cost. 📩 Have a hardware project in mind? Whether you need a new PCB designed, an existing board modified, or a design reviewed before manufacturing, send me your requirements or project files. Let's discuss how I can help bring your hardware project to life.
