About me
With over 20 years of hands-on experience and clients across 15+ countries, you're working directly with an engineer who has successfully delivered complex projects, from initial concept through production. Every design is built to work reliably, pass certification, and scale to manufacturing.
I help startups, individuals and product teams turn electronic product ideas into reliable, production-ready hardware.
Most projects don’t start with a clean spec. There is usually a rough concept, an early prototype, or a design that is not behaving as expected. That’s typically where I come in.
I work across the full development process, from system architecture and component selection through schematic design, PCB layout, firmware, bring-up, testing, and manufacturing handoff. The goal is not just to make something that works, but to build hardware that remains stable, repeatable, and manufacturable.
A big part of my work is preventing problems early. Poor power design, RF issues, EMI, or layout decisions that cause instability later are common failure points. Fixing these after prototyping is costly, so I focus on getting the fundamentals right from the start.
My work includes:
- Schematic design and multi-layer PCB design (Altium Designer)
- Embedded systems and firmware (C, C++, Rust, Embedded Linux)
- Hardware debugging and root-cause analysis
- RF design (BLE, Wi-Fi, LTE, GNSS, Sub-GHz) and antenna integration
- Power electronics (DC/DC, battery systems, charging, PoE)
- In-house validation, testing, and pre-compliance checks
- DFM/DFT and manufacturing handoff (BOM, Gerbers, assembly documentation)
I maintain a fully equipped lab for bring-up and testing, which allows issues to be identified and resolved early, before they reach production.
I’ve worked on IoT devices, wearables, medical and industrial systems using platforms such as STM32, ESP32, nRF52/nRF53, and i.MX.
I work directly with clients, keep communication clear, and stay involved until the design is stable. No handoffs, no guesswork, and no disappearing after the first prototype.
If you’re building a hardware product and want it done properly from the start, or need to stabilize an existing design, feel free to get in touch.

Portfolio
Precision Dispensing
A custom dual-transducer ultrasonic sensor was engineered using high-frequency transducers and proprietary signal processing algorithms. The innovation was in overcoming the "blind zone" that plagues conventional sensors.
Multi-Channel TEC Controller
A 3-channel TEC controller was designed with dedicated synchronous buck converters for each channel, enabling efficient bidirectional current control. The microcontroller implements independent PID loops for each TEC module, with screw terminals for easy connection.
High-Precision RTK GNSS/IMU Tracker
A tracker board designed around a u-blox RTK GNSS module paired with a 9-axis IMU featuring onboard sensor fusion for inertial navigation. Active GNSS antenna with LNA ensures excellent signal reception, while UHF connectivity enables RTK correction data. LiPo battery power with USB-C charging.
Industrial i.MX Single-Board Computer
A custom SBC designed around the NXP i.MX processor with DDR memory, featuring dual Ethernet ports, multiple USB interfaces, and expansion headers for application-specific I/O. Robust power management handles wide input voltage ranges and industrial transients.
Custom ESP WiFi Module
A custom board designed around the ESP32 chip with ISSI flash memory for program storage. The PCB includes an optimized trace antenna, JST connectors for battery and peripheral connections, and all necessary support circuitry. The layout maintains RF performance while fitting the required enclosure.
High-Power Converter
A custom switching power supply was designed with firmware-selectable constant current and constant voltage modes, paired with a precision-engineered bent aluminum heatsink. The thermal design allowed high power density while maintaining safe operating temperatures in the tight enclosure.
Compact 2kV Inverter
A cascaded modular inverter architecture was developed that allows voltage scaling through stackable stages. Advanced power electronics and thermal optimization enabled exceptional power density, while precise digital control ensures clean sinusoidal output with variable frequency capability.
