As a Top-rated Upwork freelancer and experienced Hardware Engineer, I thrive on designing and developing complete electronic systems that solve real-world engineering challenges. My work blends deep technical expertise in PCB design, RF engineering, and embedded systems with a strong focus on building production-ready, reliable, and scalable hardware products. Over the years, I’ve worked across the full hardware development cycle — from concept, schematic design, and PCB layout to firmware development, prototyping, RF optimization, and manufacturing support. I enjoy turning complex ideas into functional, manufacturable electronic systems that perform reliably in real environments. Here's a snapshot of the domains I've mastered: Hardware Specialties 💻🔌 ✅ Embedded Systems Development: Expert in designing embedded solutions using ESP32, STM32, PIC, Arduino, and Raspberry Pi (including CM4/CM5 platforms). I handle everything from low-level firmware (C/C++) to hardware integration, real-time control systems, and IoT-enabled devices. ✅ PCB Design & Hardware Engineering: Advanced experience in schematic design, multilayer PCB layout (2–16 layers), high-speed routing, power distribution, signal integrity, and EMI/EMC-aware design. I focus on turning circuits into robust, production-ready boards. ✅ RF & Microwave Engineering: Specialized in RF circuit design, antenna development, and electromagnetic simulation using CST, HFSS, ADS, and 4NEC2. My work includes LoRa, GPS, RFID, wireless communication systems, and RF optimization for real-world performance. ✅ Wireless & IoT Systems: Designing connected systems using Bluetooth, WiFi, LoRa, and custom RF protocols. I develop IoT devices for automation, monitoring, sensing, and smart control applications. ✅ Sensor & Embedded Integration: Experience with MEMS/IMU, GPS modules, RFID systems, displays, motor drivers, and industrial sensors for data acquisition and intelligent control systems. Design Tools 🧰 Altium Designer | KiCad | EasyEDA | CST Studio Suite | HFSS | ADS | MATLAB & Simulink | LTspice | NI Multisim | Proteus | 4NEC2 Project Experience 🚀 ✔ Raspberry Pi CM4/CM5 Carrier Board Development ✔ High-speed Multilayer PCB Design for complex systems ✔ ESP32, STM32 & Arduino-based embedded products ✔ RF & Antenna Design for LoRa, GPS, and RFID systems ✔ IoT & Wireless Communication Devices ✔ Motor Control & Automation Systems ✔ Power Electronics & DC-DC Converter Designs ✔ Custom Sensor-based Data Acquisition Systems ✔ Smart Home & Industrial Automation Solutions ✔ Prototype development to manufacturing-ready hardware My approach is centered around engineering precision, manufacturability, and system-level reliability. Whether it’s a small embedded controller or a complex RF-enabled multi-layer system, I ensure every design is optimized for performance, stability, and real-world deployment. I also support full product development — from initial architecture and schematic design to firmware, debugging, testing, and production assistance. I’m always excited to collaborate on innovative hardware ideas and help transform concepts into fully functional electronic products ready for manufacturing and deployment.

A client found me on Upwork for a $20 job. Convert some bank statements into Excel. Simple enough. But when I got into files something did not add up. Three full years of accounts. No reconciliation. No structure. Transactions sitting in no particular order with nothing making sense behind them. I could have just done $20 job and moved on. I did not. I told him what I found. He asked me to fix it. Four months later his books were rebuilt from zero. 2023, 2024 and 2025 fully reconstructed in QuickBooks Online. Over a thousands of transactions recorded, reconciled across bank accounts, credit cards, SBA loans, American Express business loans, equipment finance leases. Fixed asset register built for commercial properties and equipment. Depreciation schedules calculated using straight line method. Cash flow forecast prepared. His tax agent had everything they needed. Clean. Accurate. Ready. That $20 job became something else entirely. Not because I oversold myself. Because I looked properly and said what I saw. That is probably the most honest way I can describe how I work. Nine years across finance, operations, and business support. Clients in UK, US, Norway, and beyond. A Norwegian company kept me on for nearly four years. A UK healthcare business has relied on me for operations and CRM support since 2024. A few things worth knowing before you message me. I grew up in a family where nothing came easy. My father sold fruit on the street to keep six of us going. I started freelancing during COVID with no clients and no safety net because I needed it to work. That background probably explains why I take reliability seriously. It is not a soft skill to me. It is just how I operate. 100% job success on Upwork. Top Rated. 8,000+ hours. 130+ projects on Upwork. 5 star rated on PPH with 40+ reviews and 6,000+ hours completed. Long term clients across both platforms worldwide. Not because I promised them the earth. Because I just got on with it every single time. I work across a few areas and I will be straight about all of them. Bookkeeping and finance is where most of my serious work sits now. QuickBooks Online cleanups, catch-up bookkeeping, bank reconciliation, accounts payable and receivable, financial statements, cash flow tracking, and fixed asset schedules. I work in QuickBooks Online, QuickBooks Desktop, Xero, Wave, Sage, Zoho, MoneyBird, FreeAgent, and Excel. If your books are behind, I have seen worse. I will tell you what needs doing and get on with it. Operations and executive support is the second area. CRM management, inbox and calendar handling, project coordination, reporting, admin workflows, and ongoing backend work that nobody has time for but everyone notices when it slips. Then there is a third area that maybe surprises people. Over hundreds plus completed jobs cover work most freelancers would not attempt in one career. Human translation across French, Spanish, Thai, Chinese, German, Urdu, Punjabi, Korean, Portuguese, Italian, Polish, and more. Not machine translation. Clients came back repeatedly. Transcription across hundreds of hours of audio and video. Proofreading and editing across thousands of pages with clients staying on for months at a time. Interactive fillable PDF forms built from scratch for businesses, healthcare providers, and tax professionals. Virtual assistance and admin support across hundreds of hours for clients in UK, US, Europe and across regions. I know what some people think when they see a profile this broad. They think it looks fake. Or scattered. Or that nobody can actually do all of this properly. That said every skill here came from real paid work with real clients who came back. The 100% job success score is not a number I managed carefully. It is what happens when you take every job seriously regardless of if it pays $10 or $1,000. If your books are behind, your records need sorting, your inbox is out of control, your PDF needs rebuilding, your document needs translating, or your operations need someone stable who gets on with things without being chased, just send me a message. The best client relationships I have had started with one simple message. That is all it takes to find out if I am the right person to fix what is broken in your business right now. Message me and let's sort it out before it costs you more than it should. Thank you!
