Developing web services from scratch can be a daunting task, especially when you're short on time, budget, or domain expertise. However, with the advent of low-code platforms, developers can now create complex applications with ease. In this talk, we will explore the pros and cons of using low-code platforms for web service development, using an audio-processing web service as an example.

We will showcase an audio-processing web service that splits audio files into separate stems using machine learning. The web service was built using Wix Velo and AWS Batch, and will serve as a case study for demonstrating the benefits of low-code platforms. We will review the architecture of the web service, compare the development experience using low-code platforms versus traditional full-stack development, and discuss the limitations of low-code platforms.

The talk is intended for developers interested in exploring low-code platforms for their projects. By the end of the talk, you will have a better understanding of how low-code platforms can accelerate development, when to use them, and how to incorporate them into your development workflow.

The talk was first delivered in person at WixDevCon September 2022 in NYC, the recording of a webinar version can be found here: https://www.youtube.com/watch?v=vZs4d6UqEAE
