About this Gig
WHEN AUDIO HARDWARE MUST DO MORE THAN JUST MAKE SOUND.
I develop embedded audio systems for guitar effects, Hi-Fi equipment, karaoke hardware, digital audio products, and custom DSP applications.
I work across DSP algorithms, PIC32MX firmware, audio codecs, signal processing, and PCB level audio architecture to turn an audio concept into a functioning electronic system.

- HiFi Audio
- Digital Audio
- Audio Processing
- Karaoke Systems
- AirPlay Audio
SYSTEM GAINS:
- Clean Signals
- Low Latency
- Stable Processing
- Clear Routing
- Efficient Firmware
- Noise Control
ENGINEERING EDGE:

- Hardware Awareness
- Code Structure
- System Thinking
BUILD ELEMENTS:
- DSP Algorithms
- Audio I/O
- Codec Integration
- Firmware Logic
- Signal Chains
- PCB Architecture
Your audio product should have a clear signal path from input to outputnot a collection of disconnected functions.
Send your schematic, requirements, block diagram, existing firmware, or simply your concept. Let's turn the audio problem into a working system.

FAQ
What if my project is complex and requires both hardware and firmware development?
That is exactly what I do. I provide complete embedded audio solutions, including PCB design, firmware development, codec integration, DSP implementation, testing support, and production-ready deliverables.
My audio project has noise, distortion, latency, or sound quality issues. Can you solve them?
Yes. Audio performance problems are common buyer concerns. I specialize in DSP systems, audio codecs, signal processing, filtering, and PCB optimization to achieve clean, high-quality audio output.
How do you prevent the DSP from working in software but failing on hardware?
I consider the complete path—input → ADC/codec → DSP → firmware → DAC/codec → output—rather than treating the algorithm as an isolated software task.
How do I know the design will actually work and not require costly redesigns?
Every project is developed using engineering best practices, design verification, and careful component selection. I focus on creating reliable, manufacturable designs to reduce risks, delays, and unnecessary costs.
Will I receive all the source files and ownership of the design?
Absolutely. You will receive the agreed project files, including schematics, PCB files, firmware source code, and production files, giving you full control of your project.
can you work with my existing PCB or hardware?
Yes. I can review your existing schematic, PCB, MCU, codec, interfaces, and signal path before suggesting changes, helping avoid unnecessary hardware changes.
What if my audio output has noise, distortion, or latency?
I can trace the signal chain and examine gain stages, codec configuration, sampling, DSP processing, routing, and firmware timing to identify where the issue originates.
Can you work with unfinished or poorly documented firmware?
Yes. I can inspect the available source code, configuration, interfaces, and hardware assumptions first, then determine what can be retained, corrected, or rebuilt.
