Ask HN: Freelancer? Seeking freelancer? (December 2024)

Willing to relocate: no, but willing to travel/visit. I'm flexible with working hours, I usually work with clients from either Western Europe or the USA.

I do dev/devops/security, usually for startups or scale-ups or other small orgs with limited resources, and I've been doing that for 15+ years. So, if you:

* Have a slow web application that’s often down?

* Want to improve security and don’t know where to start?

* Have a legacy system that needs to be replaced?

* Are considering an acquisition but not sure about the technical side?

I can help with that. For example, in the past I have:

* Massively improved performance and reliability for a data visualization platform.

* Led a large effort to improve security for a cybersecurity SaaS.

* Built a micropayments system for a prominent media startup.

* Rebuilt an aging e-learning platform from scratch for a GDPR compliance SaaS.

* Conducted technical due diligence for acquisitions.

We've developed a Prolog-SQL hybrid language for LLMs to perform efficient RAG called Memelang. We're looking to build general LLM/RAG tools using this. And we're particularly for a database expert to develop a native database program.
