⚙️ I turn silicon and specs into smart, stable, and scalable embedded solutions.
I engineered a 30% improvement in firmware responsiveness across connected devices, helped reduce development time by 25% for a FreeRTOS based ESP32 product line, and built modular driver architectures that made it easier for hardware teams to scale from prototype to production, all while keeping performance rock-solid in the field.
As an Embedded Firmware Developer & Embedded Systems Specialist with 7+ years of experience, I design and build fast, reliable, and maintainable embedded software and microcontroller firmware for IoT and industrial products using ESP32 / STM32 / nRF52, FreeRTOS, ESP-IDF, and ARM Cortex-M architectures.
💼 What I Offer:
🔹Production-grade microcontroller firmware using C/C++ for MCUs and SoCs (ESP32, STM32F4, nRF52, ATSAM4, etc.)
🔹FreeRTOS / ESP-IDF-based systems, leveraging multi-threaded architectures for improved efficiency
🔹Advanced sensor & peripheral drivers, integrated into complex hardware ecosystems
🔹Communication stacks built on SPI, I2C, UART, BLE, MQTT, CAN, USB, Ethernet
🔹Smart devices & cloud-connected IoT products using the Espressif ESP-IDF framework
🔹Industrial automation firmware and embedded Linux/AOSP customizations (Yocto, HALs, board bring-up)
🔹Thorough documentation & end-to-end support for internal and external stakeholders
🛠️ What I’ve Been Delivering
When most teams reach out to me, they already have hardware in hand, what they don’t have is firmware they can trust in the field. So I come in, analyze what’s running, and turn “demo” firmware into production ready systems. That means:
✔ Optimizing edge-device firmware so it stays stable, responsive, and power-efficient
✔ Customizing AOSP / Embedded Linux platforms for real-world products (HMI panels, smart displays)
✔ Writing and integrating drivers for complex sensors and peripherals
✔ Handling board bring-up, BSP development, bootloaders, and kernel-level debugging
✔ Providing long-term maintenance to keep real-time systems healthy in industrial, consumer, and automotive environments
My role is simple: make sure your embedded product behaves perfectly not just on your bench, but in your customer’s hands.
💻Embedded Systems Expertise
Languages: C, C++, Python (tooling & scripting)
MCUs & SoCs: ESP32, STM32 (F0/F4), nRF52, ATSAM4, ARM Cortex-M
OS & Frameworks: FreeRTOS, ESP-IDF, Zephyr, Yocto, Buildroot
Connectivity & Protocols: SPI, I2C, UART, CAN, BLE, MQTT, Ethernet, USB
Tools: GCC, OpenOCD, JTAG/SWD, Logic Analyzers, Git, Jira
If you’re building something that doesn’t fit the usual embedded mold, I’d be glad to hear about it. Some of my best work has come from partnering with teams tackling problems that require a custom-crafted solution.
Let’s connect and take your project to the success it deserves.

I am a Senior Embedded Linux Programmer and IT/Infrastructure Consultant with nearly 40 years of overall development experience. I specialize in getting tough hardware and networking projects off the ground—or rescuing existing projects that have hit a wall.
Because my background spans the entire stack—from bare-metal custom Linux kernels to advanced enterprise server configurations—I can troubleshoot and build systems that most single-discipline developers cannot.
Here are my core areas of expertise:
• Embedded Linux & BSP: Custom firmware, kernel drivers, and deep optimization for SoC boards (Raspberry Pi, Orange Pi, NanoPi, etc.). I have extensive experience with Buildroot, Yocto, MAC-PHY communication, and precision timekeeping (PTPv2/IEEE 1588v2).
• Networking & Telecom: 7+ years building 4G/LTE protocols (MAC-level, EPC, QoS). I regularly handle BGP routing issues, VPN implementations (IPsec/StrongSwan), and complex traffic convergence.
• Edge AI & Computer Vision: Building optimized pipelines for video surveillance, real-time object tracking, and deploying AI models directly on edge devices.
• Infrastructure & Email Systems: Advanced Postfix customization. I routinely design secure email obfuscation workflows, generate robust SPF/DKIM records for domains, and manage complex DevOps tasks like cloud migrations and remote work infrastructure. Zabbix and Grafana infrastructure monitoring, custom agents, alerting and visualization.
Past Successes:
• Led the full-lifecycle development of the MaxBridge 4G solution, successfully deployed across four countries.
• Core BSP Engineer on the highly successful Carsifi project.
• Rework old systems with new core elements, incorporating existing hardware protocols.
I don't just write code; I solve system-wide problems. If you need someone who understands exactly how your hardware talks to your network, send me a message and let's discuss your project.

✅𝙏𝙊𝙋-𝙍𝘼𝙏𝙀𝘿 𝙀𝙢𝙗𝙚𝙙𝙙𝙚𝙙 𝙎𝙮𝙨𝙩𝙚𝙢𝙨 𝘿𝙚𝙫𝙚𝙡𝙤𝙥𝙚𝙧✅
I design and build firmware and hardware for everything from consumer gadgets and IoT products to sports tech and medical devices—delivering smart, connected solutions that work. Backed by 10+ years of hands-on experience across a wide range of embedded systems, I bring a strong focus on quality, performance, and getting things done right.
💻 𝗙𝗶𝗿𝗺𝘄𝗮𝗿𝗲 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁
Over the years, I've mastered the art of creating firmware across the spectrum - from simple 8-bit to powerful 32-bit microcontrollers. Here's where I shine:
🔹 𝙎𝙏𝙈 - I've worked with virtually every STM32 variant out there (F, L, G, H, U, WB, WL, and MP series). Whether you need ultra-low power consumption or blazing performance, I can make these chips sing.
🔹 𝘼𝙏𝙈𝙀𝙂𝘼 & 𝘼𝙏𝙎𝘼𝙈 - From the classic ATMEGA328 that powers Arduino to the powerful SAMA5, I've built everything from smart home devices to industrial control systems with these reliable workhorses.
🔹 𝙋𝙄𝘾 - I've tamed the entire PIC ecosystem - from basic 8-bit controllers (PIC16F/18F) to the powerful 32-bit PIC32MZ. Perfect for cost-sensitive projects that still need serious capability.
🔹 𝙀𝙎𝙋 𝙈𝙤𝙙𝙪𝙡𝙚𝙨 - Need WiFi or Bluetooth in your project? I've developed countless solutions with ESP32 and ESP8266, creating connected devices that are both responsive and power-efficient.
🔹 𝙉𝙤𝙧𝙙𝙞𝙘 𝙣𝙍𝙁5𝙭 - When battery life is critical, I turn to the nRF family. I've crafted BLE devices that run for months or years on a coin cell, including complex mesh networks that maintain rock-solid connections.
This diverse toolbox lets me pick exactly the right platform for your specific needs, whether you're creating consumer gadgets, industrial equipment, medical devices, or the next big IoT innovation.
⚙️ 𝗛𝗮𝗿𝗱𝘄𝗮𝗿𝗲 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁
Hardware isn't just about connecting components—it's about creating something that works reliably in the real world. After a decade of designing electronics, here's what I bring to the table:
🔹 𝙋𝘾𝘽 𝘿𝙚𝙨𝙞𝙜𝙣 - I've designed everything from simple 2-layer boards to complex 10-layer systems using KiCAD. Each design balances performance needs with manufacturing realities—because a great design that can't be built isn't actually great. I also provide detailed 3D models of the board, helping you visualize the final product and identify mechanical integration issues early.
🔹 𝙀𝙈𝘾-𝙍𝙚𝙖𝙙𝙮 𝘿𝙚𝙨𝙞𝙜𝙣𝙨 - I've developed a solid track record of creating boards that pass EMC testing. Through careful attention to ground planes, component placement, and proper shielding techniques, I minimize interference issues before they become problems. My designs consistently meet compliance requirements without costly redesigns.
🔹 𝙎𝙞𝙜𝙣𝙖𝙡 𝙄𝙣𝙩𝙚𝙜𝙧𝙞𝙩𝙮- High-speed designs can be tricky beasts. I've learned the hard way that when your data is flying around at hundreds of MHz, you can't just connect point A to point B and call it done. My designs account for real-world challenges like impedance matching and controlled trace lengths, so your signals arrive clean and clear, even when surrounded by noisy components.
🔹 𝙏𝙚𝙨𝙩 𝙅𝙞𝙜𝙨 𝙏𝙝𝙖𝙩 𝙎𝙖𝙫𝙚 𝙏𝙞𝙢𝙚 - I build custom test fixtures for production testing that improve quality while reducing test time. From programming jigs to complete functional testers, I ensure your manufacturing process is smooth and efficient.
Every board I design gets the same attention to detail whether it's a simple sensor node or a complex control system. My goal is hardware that just works, without excuses or mysterious failures.
🛠️ 𝗖𝘂𝘀𝘁𝗼𝗺 𝗗𝗿𝗶𝘃𝗲𝗿 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁
I create robust drivers for diverse hardware components:
🔹 Sensors - IMUs, GPS, temperature, pressure, and more
🔹 User Interfaces - Touchscreens, displays, input devices
🔹 Wireless - WiFi, BLE, LoRa, Zigbee, UWB
🔹 Storage - EEPROM, Flash, SD interfaces
My drivers work reliably even in challenging environments.
🚀 𝗘𝗻𝗱-𝘁𝗼-𝗘𝗻𝗱 𝗣𝗿𝗼𝗱𝘂𝗰𝘁 𝗗𝗲𝘀𝗶𝗴𝗻 𝗖𝗼𝗻𝘀𝘂𝗹𝘁𝗶𝗻𝗴
I help transform ideas into reality by:
🔹 Validating concepts
🔹 Selecting optimal hardware components
🔹 Designing scalable firmware architectures
🔹 Creating functional prototypes
From concept to market-ready product, I balance performance, cost, and power efficiency while ensuring your vision becomes reality.
