The feature was powered by flexsearch — a zero-deps full-text search library; ooh boy I'm a big fan of lightweight and no/low dependencies. I dug into how Nextra uses this to index content at build-time for search; it was interesting.

We map the TUS[0] protocol to S3 multipart upload operations. This lets us obscure the S3 bucket from the client. The TUS operations are handled by a dedicated micro-service. It could be done in a Lambda or anything.
Once the upload completes we kick off a workflow to virus scan, unzip, decrypt, and process the file depending on what it is.
For virus scanning, we started with ClamAV[1], but eventually bought a Trend Micro product[2] for reasons that probably don't apply to you. It is serverless based on SQS, Lambda, and SNS. Works fine.
Once scanned, we do a number of things. For images that you are going to serve back out, you for sure want to re-encode those and strip metadata. I haven't worked directly on that part.
