I’m an Embedded Systems Engineer specializing in Firmware development, with nearly 10 years of experience in the field. I have extensive experience with the following microcontroller families: PIC16F/18F, STM32 and other ARM Cortex-based MCUs, ATmega, ATtiny, SAMD—and most recently, the ESP32 family for IoT devices. 1️⃣My strongest skill is an in-depth knowledge of MCU internal architecture and operating principles: ⚡Memory organization, ⚡Instruction sets and execution, ⚡Device configuration, ⚡Watchdogs, ⚡Interrupt services (including multiple-interrupt handling), and ⚡Peripheral management. I’ve worked with virtually all standard peripherals found on modern MCUs— 🚀 Precise Timer usage; 🚀 PWM drivers; 🚀 Capture-Compare units; 🚀 ADCs; DACs; and 🚀 Serial Communications (I²C, SPI, USART, I²S). Less common peripherals I’ve tackled include the STM32 🔹AES encryption accelerator; the PIC16F’s 🔹NCO and 🔹logic-gate features; the PIC18F 🔹USB module; and the ESP32’s 🔹PDM and 🔹I²S interfaces and various other specialized modules. ➡️This deep understanding of MCU internals lets me write high-quality code with very few bugs from the outset, and it makes debugging far faster in later development stages. 2️⃣Hardware integration I deliver seamless, efficient hardware integration for: 🔹Sensors (analog and digital: temperature, humidity, light, voltage) using SPI, I²C, 1-Wire, USART, etc. 🔹Input devices from simple buttons, keypads, potentiometers, and rotary encoders to touchpads and sliders. 🔹Output devices including LCDs (various sizes), OLEDs, addressable LEDs, 7-segment displays, touchscreens, and more. I go beyond plain text and primitives, 🎨crafting eye-catching UIs with attractive fonts, colors, images, and animations whenever possible. 3️⃣I can develop—and maintain—a complete embedded-system firmware from start to finish, ensuring it’s easily maintainable by future engineers. When your embedded system is part of a larger ecosystem (e.g., IoT devices or desktop/mobile-controlled systems), I’ve implemented higher-level protocols like USB, Bluetooth/BLE, HTTP, and MQTT. I write clean, well-documented firmware APIs that integrate effortlessly into any larger system. 4️⃣An invaluable skill I bring is the ability to emulate missing peripherals entirely in software—avoiding the time, cost, and chaos of a board redesign. When hardware truly falls short, I step in to replicate its functionality in firmware, keeping development on schedule and often yielding more flexible, upgradable solutions. Of course, this isn’t a cure-all: some features simply demand a hardware revision. 5️⃣When required, I code “close to the metal” in low-level C or even Assembly. I’ve worked on legacy chips (e.g., Intel 8051 and 6502 derivatives) where assembly-only firmware was essential. 6️⃣Circuit and PCB design Although my primary focus is firmware, I hold an electronics engineering degree and am proficient at reading schematics. I collaborate smoothly with hardware designers and can propose elementary hardware solutions when needed. 7️⃣I’m a thorough researcher who always studies documentation carefully before drawing conclusions. While this can slow initial progress, it pays off with faster, more reliable development later on. 8️⃣Other skills and interests Windows desktop app development (WinForms) Web scraping (I’ve built sports-results scrapers) Retro game development (I’ve completed a SNES game) You can find many of my projects—console utilities, ASCII-art games, web scrapers, and more—on my GitHub page.

I provide end-to-end product-development support across architecture, electronics, PCB design, prototype validation, firmware coordination, enclosure integration, manufacturing preparation, and production support. Attention to detail is central to how I work. I review architecture, interfaces, power, component selection, grounding, thermal behaviour, RF performance, testability, compliance, sourcing, assembly, and manufacturing constraints before they become expensive physical problems. Clients typically engage me for: 1. Converting Arduino, STM32, ESP32, nRF52/nRF53, NXP, TI, i.MX, Raspberry Pi, other development-platform prototypes into custom electronics 2. Finalizing hardware architecture before major development expenditure 3. Developing complex analog, digital, power, RF, wireless, or mixed-signal hardware 4. Reviewing schematics and PCB layouts before fabrication or production release 5. Correcting noisy, unstable, thermally stressed, or unreliable designs 6. Adding senior electronics capacity to an internal product team 7. Preparing electronics for EMI/EMC testing and manufacturing Core areas of work ✅ Hardware Architecture and Feasibility: I evaluate system architecture, processing platforms, power requirements, interfaces, sensing, protection, component dependencies, enclosure constraints, and development risks before the design becomes expensive to change. ✅ Circuit and Advanced PCB Design: I work across analog, digital, power, RF, wireless, sensing, control, battery-operated, low-power, and mixed-signal electronics. My PCB experience includes up to 32 layers, controlled impedance, differential pairs, length matching, high-speed interfaces, blind and buried vias, HDI, advanced stackups, compact placement, high-current and high-voltage sections, signal and power integrity, grounding, thermal planning, antenna placement, RF keepouts, DFM, DFA, and DFT. Primary tools: Altium Designer, KiCad, EasyEDA, EAGLE, and Proteus. I also create schematic symbols, PCB footprints, and integrated 3D library data. ✅ PCB and Hardware Design Review: I assess circuit correctness, design margins, power-tree stability, protection, component suitability, lifecycle risk, placement, routing, return paths, thermal performance, EMI/EMC exposure, testability, DFM, DFA, DFT, and production readiness. Findings are prioritised by severity. ✅ Prototype Bring-Up and Testing: I maintain an equipped electronics laboratory for prototype bring-up, measurement, debugging, and validation. ✅ Design for Excellence: My process incorporates DFM, DFA, DFT, EMI/EMC-conscious design, component lifecycle planning, debug access, BOM awareness, and structured engineering reviews. ✅Relevant experience includes IoT, wearables, industrial and medical electronics, wireless systems, battery-powered products, automotive hardware, consumer electronics, and reverse engineering. Relevant hardware areas: 🏭 Industrial automation and monitoring 🏠 IoT and connected products ⌚ Wearable and compact electronics ⚕️ Medical and measurement-related electronics 🚗 Automotive and transportation hardware 📡 Wireless, RF, BLE, Wi-Fi, LoRa, and GNSS systems ⚡ Power management, battery systems, and high-current hardware 🛰️ Reverse engineering, design recovery, and product benchmarking ✅Direct accountability: I work directly with clients and remain involved in architecture, critical technical decisions, design reviews, and communication. PCB Must Innovations supports documentation, prototyping, sourcing, and manufacturing preparation through a structured process. No unexplained handoffs. No guesswork hidden behind design files. No disappearance after the first prototype. ✅Global availability: I support clients across the USA, UK, Europe, Australia, Canada, and other markets, with planned overlap for meetings, reviews, and handoffs across major time zones. I am best suited to commercially serious projects where reliability, performance, communication, and production readiness matter more than the lowest initial quotation.
