I’m a Senior Software Developer specializing in C++, Embedded C, and systems level software, with experience building reliable applications, embedded systems, device software, and performance critical solutions. I work close to the hardware when needed, while also bringing modern software engineering practices to architecture, APIs, testing, debugging, and deployment. CORE EXPERTISE C / C++ Development • Modern C++ • Embedded C • Object oriented and low level programming • Memory management • Multithreading and concurrency • Performance optimization • Data structures and algorithms • Cross platform development • Debugging and troubleshooting Embedded Software • Firmware development • Microcontroller programming • Hardware and software integration • Device drivers • Communication protocols • Real time systems • Interrupts, timers, and peripherals • Memory constrained environments • Hardware debugging Systems and Connectivity • UART / SPI / I²C • CAN / CAN FD • TCP/IP • Bluetooth / BLE • Ethernet • Serial communication • REST and API integration Additional Software • Linux • Windows • Python • JavaScript / TypeScript • React • Node.js • REST APIs • SQL / NoSQL databases • AWS / Azure Cisco Networking • Cisco router configuration and troubleshooting • TCP/IP networking • IPv4 / IPv6 • Subnetting and IP addressing • VLANs and inter-VLAN routing • DHCP and NAT • Access Control Lists (ACLs) • Static routing • OSPF • Ethernet networking • Network troubleshooting • Network device integration • Basic VPN configuration WHAT I CAN HELP YOU BUILD • Embedded firmware from scratch • C and C++ applications and libraries • Hardware control and device software • IoT and connected device systems • Real time and performance critical applications • Device communication and protocol implementations • Legacy C/C++ modernization • Debugging memory, concurrency, and performance issues • Embedded to cloud integrations • Desktop and backend applications that communicate with hardware WHY CLIENTS HIRE ME Some software problems cannot be solved effectively with another high level framework. When performance, memory usage, latency, hardware access, or deterministic behavior matters, C and C++ are often the right tools. I focus on understanding the complete system, including hardware, firmware, software, communication, performance, and reliability, rather than treating each layer as an isolated piece. Whether you are developing a new embedded product, maintaining an existing C/C++ codebase, connecting hardware to software, or solving a difficult performance problem, I can work from the low level implementation through the higher level application layer. I build software that is efficient, reliable, maintainable, and designed to work in the real world. less -

My core expertise is in Embedded C++, C++, STM32, ARM-based systems, RTOS, and microcontroller programming, including STM32 and ESP32 platforms. I work across the full embedded development cycle, from understanding hardware requirements and designing firmware architecture to implementation, debugging, testing, and integration. I can help with: • Embedded software and firmware development • STM32 / ESP32 microcontroller programming • Embedded C++ and C++ development • ARM-based embedded systems • RTOS-based applications and task management • Hardware-software integration and debugging • Peripheral and communication interface development • PCB design, PCB layout, and electronics integration • Python-based tools, utilities, and test automation • C#, .NET, and ASP.NET applications supporting embedded systems • Firmware maintenance, optimization, and feature development I’m comfortable working with both new product development and existing embedded codebases. I focus on writing structured, maintainable firmware and making sure the software works reliably with the underlying hardware. I also understand the practical side of embedded development—timing constraints, resource limitations, hardware dependencies, debugging, and communication between firmware and electronic components. This helps me approach projects from both the software and system perspective rather than treating firmware as isolated code. Whether you need firmware developed from scratch, an existing STM32/ESP32 project improved, an RTOS-based system implemented, or embedded software integrated with custom electronics, I can work from your requirements, technical documentation, schematics, or existing source code. Why work with me? • 8+ years of practical embedded development experience • Strong focus on C++, STM32, ARM, RTOS, and firmware • Comfortable working across software and hardware boundaries • Clean, maintainable, and production-oriented development • Clear communication and a systematic approach to debugging • Able to work with both new projects and existing systems My goal is simple: build embedded software that is stable, efficient, maintainable, and ready to work reliably with the hardware it controls.

It does not prove that it will survive the next hardware revision, pass through EVT cleanly, behave the same across multiple builds, or remain reliable once it leaves the bench. That is where hardware projects become expensive. I work with founders and small product teams to take embedded products from concept or working prototype toward a credible pre-EVT baseline. The objective is not simply to produce a schematic, route a PCB or make firmware compile. It is to remove as much uncertainty as practical before that uncertainty becomes another PCB spin, failed certification attempt, production delay or field problem. My work covers electronic architecture, schematic and PCB design, component selection, firmware, SMD prototype assembly, bring-up and validation. I maintain my own electronics lab, so I can build the resulting hardware, measure its behaviour and challenge assumptions before handing it back. My strongest area is connected and wireless hardware: IoT sensors and gateways, LoRa/LoRaWAN, LTE, BLE and Wi-Fi, together with low-power and battery-operated systems. I work across ESP32, nRF52, STM32 and other platforms, choosing the architecture around the product rather than forcing the product around a familiar development board. Typical work includes: 🔹 Converting development-board prototypes into purpose-built hardware 🔹 Finding power, RF, interface and reliability problems before EVT 🔹 Bringing up and debugging first PCB builds 🔹 Measuring power consumption and wireless performance 🔹 Integrating electronics with enclosures, connectors and wiring 🔹 Separating what has been proven from what is still assumed A board can pass ERC and DRC, boot correctly and still carry expensive problems forward. That is why I rarely treat “it works” as the end of the engineering question. I am probably not the right engineer if you simply need the cheapest route from a schematic to Gerber files. I am a better fit when the next revision needs to reduce uncertainty before more money is committed to tooling, certification, production or deployment. If you already have a prototype, requirements or an early design, show me where it stands and what still needs to be proven. less -
