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 -
