Applying my vast experience in Arduino, electrical engineering, electronics, and microcontroller programming, I am confident that I'm well-suited to handle your project. In addition to having a deep understanding of DAC boards, audio playback technology and power supply design for battery-operated devices - core elements of your prototype creation task - I bring an unparalleled expertise in software and hardware integration. My experience with Xcode paired with my knowledge of MATLAB, LTSpice and Vivaldi will enable me to build you a board that is not only completely functional but can also simulate analog/digital signals entirely. Having professional skills in compiling code and using tools like distortion analyzers as well as frequency sweeps will prove invaluable in maintaining superior audio quality during the conversion process. Using a sophisticated arm with Wi-Fi only aligned with a 44.1 kHz clock recovery feature -a feature worth discussing-, are surefire ways to ensure precision. To this end, I propose incorporating the best software volume attenuator available for tailored sound adjustments.

With over 8 years of diverse web and mobile development experience, my skills set align perfectly with the demands of your prototype streaming DAC amplifier project. My proficiency in Xcode, MATLAB and Vivaldi, along with my determined ability to use Distortion Analyzer and conduct frequency sweeps, promise reliable circuit design and audio technology integration. As you seek a freelancer who 'compiles' code, look no further. I am highly equipped for MPC programming and would joyously undertake the task of building a totally functional prototype board. Having compiled codes for over 40 websites and 10 mobile apps on noteworthy frameworks such as React Native, I offer clean, efficient and well-documented code practices that ensure seamless functioning. Considering the crucial nature of your project’s power supply design, let me highlight my expertise in sustaining battery-operated devices. I have profoundly worked on Google Map & Social API integrations for applications that run under heavy load but need long battery lives like location tracking apps. Utilizing this knowledge for your audio playback project will assure you not just a DAC board that converts digital signals into sublime analogue audio but one that runs flawlessly off battery power for extended periods. With my passion for perfection and love for amplified audio quality, I pledge to give your audiophile dreams solid ground in the form of this prototype streaming DAC amplifier board!
