Service 07
RAG Systems & AI Knowledge Assistants
Retrieval-augmented generation over your own documents, for chat or for voice. Built so answers come from your data, with retrieval quality measured rather than assumed.
What this service covers
Most retrieval projects fail on retrieval, not generation. If the wrong passages come back, no amount of prompt tuning saves the answer, it only makes the model confidently wrong. So the work starts with how documents are parsed, chunked and embedded, and with measuring retrieval quality instead of assuming it.
I build RAG systems over your content: ingestion, vector storage in Supabase, pgvector or Pinecone, semantic search, reranking, and the generation layer on top. Where the product is multi-tenant that also means per-tenant isolation of data and embeddings, so one customer's documents never surface in another customer's answers.
RAG inside a voice agent is a harder problem than RAG in a chat window, and it is the version I most often get asked for. A chat user will wait two seconds for a retrieval round trip. A caller will not. That means aggressive caching, retrieval running in parallel with the model's opening words, and a fallback answer ready for when the search is simply too slow to wait for. See where voice latency actually goes.
On Trainizi this pipeline turned corporate training documents into structured mini-courses for roughly 10,000 learners and about 5,000 generated courses.
What you get
- Document ingestion, parsing and chunking pipeline
- Vector storage and semantic search with reranking
- Retrieval evaluation against a real question set, so quality is a number not an opinion
- Latency-aware retrieval for voice: caching, parallel lookup, and a fallback path
- Multi-tenant isolation of documents and embeddings
- Citations in answers, so users can check where a claim came from
How I work
Four stages, and you always know which one you are in
The same process whether the engagement runs two weeks or a year.
Understand the business
I ask product-level questions before quoting, so the work is scoped against what the business needs, not just the ticket as written.
Architecture in writing
You get the proposed architecture in writing before any code is committed. Disagreements happen on the document, where they are cheap.
Delivery in milestones
Work ships in milestones with regular updates, so you always know what has landed and what is next.
Documented handoff
Code is documented and handed off cleanly. Your future engineers should not have to reverse-engineer my decisions.
Direct Project Enquiry
Tell me what you are building
Share what you are building and where it is stuck. If a managed platform already solves it, I will say so. I review every enquiry personally and reply within about four hours.
- 1Send your project goal and the services you think you need.
- 2I review the context and whether I am the right fit.
- 3You get a direct reply with a practical next step.
International projects welcome
I work in English by email, video call or through Upwork, from GMT+7 with overlap hours for US and EU teams.
