Audio Software Developer

Fiverr • Self-employed

Jan 2021 - Present5 yrs 4 mos

I am a self-employed audio software developer specializing in professional audio plugins, virtual instruments, and custom DSP tools. I have worked with around 20 clients across music production, sound design, sample libraries, independent plugin development, and commercial audio software. My role is usually to take a creative idea, prototype, or unfinished project and turn it into a clean, reliable, release-ready product. I build the parts that make audio software feel professional: strong DSP, intuitive controls, clean UI/UX, stable plugin architecture, preset systems, sample playback, effects processing, optimization, installers, code signing, and cross-platform deployment. What separates my work from general software development is that I understand both the engineering and the sound. I know how plugins are actually used by producers, how controls should feel, how sound design choices affect the product, and how to turn a rough concept into something people can use confidently in a DAW. I work with JUCE, HISE, iPlug2, C++, Faust, Max/MSP, and modern audio development workflows. From simple utility plugins to custom effects, sample-based instruments, and experimental audio tools, I help clients build software that sounds good, looks professional, and is ready for real-world use. **Note: I've never worked for the company Fiverr, this is simply a glitch in their platform.

    Michael has been so easy to work with. He understood my vision for my novel plugin from the get go and brought it to life. If I ever have any questions or comments, he has responded to them swiftly and even brought up ideas/concerns that I did not think of or anticipate. Highly recommend!
