If a client delivery depends on changing embeddings, chunking, or reranking, better average scores can still hide regressions on important queries.

I offer an independent review of existing retrieval results for teams facing that decision.

For $400, I compare two configurations across up to 30 agreed queries and deliver:

- Query-level regressions and recoveries.

- Cases where required supporting evidence is missing.

- Scoring inconsistencies that could affect the comparison.

- Reproducible findings and recommended follow-up checks.

The review can support an acceptance or release decision within the agreed scope. It doesn’t certify the entire system or include implementing fixes.

You’ll need existing evaluation queries, expected evidence, and comparable retrieval exports. Delivery target: seven days after we confirm compatible inputs.

In a public RouteMind audit, I found 15 scoring discrepancies that the maintainer independently reproduced and corrected.

Sample deliverable:

https://github.com/devBorgesr/edp-audits/blob/main/samples/ROUTEMIND_BUYER_SAMPLE.md

If you have an upcoming handoff or migration, send me the deadline, what’s changing, and what evaluation data you already have. I’ll check whether the review fits before discussing payment. Please keep client data private.

I'm offering independent retrieval regression audits for AI startups, RAG developers, and agencies preparing changes to production retrieval pipelines.

The problem: a new embedding model, chunking strategy, or reranker can improve aggregate metrics while silently losing evidence on important queries.

A real example: I independently audited the open-source RouteMind benchmark and identified 15 scoring discrepancies across 1,400 query/arm results. The maintainer reproduced the findings and incorporated corrections.

My $400 audit includes:

• Up to 30 selected evaluation queries.
• Comparison of 2 compatible retrieval configurations.
• Query-level regression and recovery analysis.
• Review of missing supporting evidence.
• Reproducible technical report and limitations.
• Recommended follow-up checks.

Delivery target: 7 days after compatible evaluation inputs and scope are confirmed.

Public sample report:
https://github.com/devBorgesr/edp-audits/blob/main/samples/ROUTEMIND_BUYER_SAMPLE.md

This is a focused independent QA review, not full production certification or implementation of fixes.

If your team is migrating embeddings, changing retrieval logic, or investigating unexpected regressions, DM me a brief description of your pipeline. I'll confirm whether your evaluation data fits the audit before discussing payment.

I’m the France-based builder of M2M Sentinel by Akselis. I built and deployed its Node HTTP API, including authentication and durable transactional quota/payment state, plus an SDK and local adversarial/regression tests.

Pricing is agreed per scoped milestone before any work.

Availability: open to scoped Node/API inquiries; any work start and timing would be agreed after fit, acceptance test, and funding.

If you own a relevant Node/API problem, reply or DM a short brief so we can check fit.
