Based in Powhatan, Virginia. I am an electrical and firmware engineer with over 10 years of experience, and 3 years of experience in the space industry. I have a Master of Science degree in Electrical Engineering. The past 3 years I've worked at a space startup. I can assist clients with: • Electronic circuit design (analog and digital) • PCB layout • Embedded systems programming and debugging • Zephyr RTOS • Writing custom bootloaders • Vorago Cortex M4, PIC, AVR, MSP430/432, STM32 • GCC compiler and associated tools • Skilled in handling large software projects within teams (including Git/SVN) • Prototyping and enclosure design (3D printing, CNC machining) • Surface-mount soldering Interfaces: SPI, I2C, CAN, UART, A/D, D/A, PWM Tools: Altium Designer, KiCad, Fusion360 Experience in electromagnetic simulation and signal processing, underpinned by a strong background in mathematics and physics. Noteworthy achievements include having software currently deployed in space and hardware scheduled to reach orbit next year. I also have a well-equipped electronics lab and machine shop to support my projects. I can quickly 3D print or CNC mill enclosures, do surface mount soldering, and diagnose issues using a variety of test equipment.

I help clients turn hardware ideas into working, tested, and reliable prototypes. Whether you need a sensor-based system, an Arduino firmware solution, or a simulation/model to validate your design. I deliver clean, documented, and real-world-ready work. I specialize in: Arduino / Embedded Systems – Sensor integration – Signal conditioning & filtering – Analog front-end design – Real-time data processing & data logging – Prototyping + wiring diagrams Modeling & Simulation (GNU Octave / MATLAB / Simulink) – Dynamic system modeling – Algorithm prototyping – Signal processing simulation – Control system analysis & visualization Python & C++ Engineering Application Development – Desktop engineering tools – GUI applications (visualization, analysis, calibration dashboards) – Apps for hardware interaction (serial/BLE sensor data, plotting, parsing) – Engineering-focused utilities that support testing or validation workflows Typical Projects I Build: Arduino systems using sensors such as temperature, humidity, pressure, distance/ultrasonic, infrared, IMUs, gas sensors, optical sensors, and more. Sensor systems with filtering, calibration, and noise-reduction Python/C++ GUI tools for data collection and engineering analysis Octave/MATLAB models for simulation and algorithm development If you want an engineer who can think critically, communicate clearly, and deliver hardware/software that actually works, I’d be glad to help.

50+ hardware and embedded systems projects delivered, from concept through manufacturing. Full project lifecycle ownership: requirements → schematic → PCB layout → firmware → prototyping → testing → DFM/production handoff. Projects spanning industrial electronics, IoT devices, RF systems, wearables, and battery-powered products. I design and build hardware products that survive real-world contact — not just designs that work in simulation. For 6+ years, I've taken products from a blank schematic to manufactured, field-deployed hardware: industrial electronics, IoT devices, RF systems, and embedded platforms used in real industrial and consumer environments. I work across the full stack — system architecture, PCB layout, firmware, prototyping, and DFM — so you get one engineer who understands how a firmware design decision affects the PCB, and vice versa. If you need someone who can own a hardware product end-to-end, or step into a specific phase (schematic review, firmware bring-up, RF tuning, manufacturing prep), I can help. WHERE I ADD THE MOST VALUE Custom PCB design, 2–12 layers, including high-speed digital and RF layouts EMI/EMC-aware design and Design for Manufacturing (DFM) Embedded firmware in C/C++ for ESP32, STM32, nRF52/nRF53, RP2040, and ARM Cortex-M platforms IoT connectivity: Wi-Fi, BLE, LoRa, GSM/LTE, GPS/GNSS, cloud-connected devices Industrial communication: UART, SPI, I²C, RS485, Modbus, CAN Bus Power electronics: battery management systems (BMS), DC-DC converters, SOC/SOH estimation, industrial power monitoring Prototype-to-production support, including BOM creation and manufacturing handoff RECENT WORK Industrial gas metering system (EVC V5) — redesigned the hardware architecture with RS485, CAN Bus, and Modbus communication, built to meet EMI/ESD protection and hazardous-environment requirements. Ground Penetrating Radar — designed a 100–900 MHz subsurface sensing system built around a high-efficiency Class-E RF power amplifier and custom embedded electronics. EEG smart glasses — developed wearable electronics for brainwave acquisition, signal conditioning, embedded processing, and wireless transmission. Dual-MCU wireless audio platform — low-power architecture combining nRF5340 and ESP32-S3, with BLE, Wi-Fi, secure storage, and advanced power management. Energy monitoring & battery management platform — multi-source monitoring across AC power, solar generation, and battery storage, with SOC/SOH estimation, GSM connectivity, Ethernet, and remote monitoring. High-power RF amplifier — 100 MHz Class-E design delivering up to 1 kW output. Multiple ESP32-based industrial and consumer products — automation, environmental monitoring, sensing, and data acquisition. Aero-Guide robot — autonomous, AI-assisted navigation platform, finalist in a national engineering competition. WHAT YOU GET WORKING WITH ME Clear technical communication from day one — I'll tell you early if something won't scale, won't pass EMC, or won't be manufacturable, rather than letting you find out after fabrication. Deliverables built for handoff: schematics, PCB layouts, Gerbers, BOMs, manufacturing files, firmware, and documentation — organized so another engineer (or your future self) can pick them up. Fast, practical problem-solving when prototypes don't behave as expected. A focus on shipping reliable, buildable hardware — not just a working bench demo. Outside of engineering, I spend time mountain trekking, with expeditions to several major peaks in Pakistan, including base camps of multiple 8,000m mountains. It's where I keep my planning and problem-solving instincts sharp under pressure — skills that translate directly into debugging hardware at 2 am before a deadline. If you have a hardware or firmware challenge — from a rough concept to a stalled prototype that needs fixing — I'd be glad to take a look and tell you honestly what it'll take to get it done right.
