RAG System Upgrade | LLM Engineer
We brought in this team for a consultation on our RAG based support chatbot, and honestly it was one of the most useful two hours we've spent on the project so far
Within the session they had already mapped the real bottlenecks in our architecture, from chunking and embeddings through to retrieval and generation, and explained clearly why our answers were inconsistent Their depth in Artificial Intelligence and Machine Learning was obvious immediately, and they clearly work with Deep Learning and Natural Language Processing systems in production, not just in theory
What stood out most is how fast they moved We expected a general conversation about RAG best practices, instead we got specific Python level recommendations we could act on the same day, some improvements were things we could ship within hours once we understood what to change
They were equally comfortable talking through our JavaScript and React front end integration and how the chatbot connects into our existing Data Science workflows, so the advice fit our actual stack instead of a generic playbook
If you need a team that understands Python, Artificial Intelligence, Machine Learning, Deep Learning, Natural Language Processing, and Data Science at a hands on level, and can turn a two hour consultation into a clear action plan, this is who I'd call

Seeking Developer(s) for Micro-SaaS MVP for Contextual XLIFF File Translation using GPT-4o
I hired this developer to build an MVP for a micro-SaaS aimed at freelance translators and agencies, and I'm really happy with the results! They created an easy-to-use platform that smoothly handles XLIFF files and outputs accurate French translations. They went beyond what I expected by suggesting helpful improvements, which made the final product even better. Communication was always clear, and the project was delivered quickly and within budget. Highly recommend working with them!
