Augmented an established New York fintech team with 3 senior AI & data engineers within 72 hours to build an internal autonomous regulatory intelligence copilot.

The Challenge:

Client was drowning under 4,000+ quarterly SEC compliance filings and financial prospectuses. Off-the-shelf models hallucinated and could not guarantee deterministic citations.

nexRsolve Engineering Solution:

nexRsolve deployed 2 LLM specialists and 1 MLOps architect. Built a hybrid dense/sparse retrieval pipeline using Qdrant, reranking models, and strict zero-hallucination guardrails.

Guaranteed Live Timezone Overlap

The biggest failure mode in staff augmentation is communication lag. nexRsolve engineers shift their working hours to guarantee 4 to 8 hours of live, synchronous overlap with your team in North America, Europe, or Asia-Pacific.

Trusted by Engineering Executives

Here is how CTOs and heads of engineering across North America, Europe, and the Asia-Pacific describe partnering with nexRsolve.

“We needed to ship an institutional RAG search pipeline for 4,000+ SEC filings. nexRsolve matched us with two senior AI engineers in 48 hours. They weren't just writing prompts; they designed custom vector reranking algorithms and our production release went live 5 weeks ahead of schedule.”

Julian Vance

Chief Technology Officer • Apex FinTech Capital
New York, USA

“The timezone overlap was our biggest concern with remote staff augmentation. With nexRsolve, our engineers in London and Berlin had 7 hours of daily live overlap with our dedicated pod. Pull requests were reviewed immediately, and our Black Friday transaction peak went off with zero latency spikes.”

Hannah Schneider

VP of Engineering • OmniPay Global Ltd
Berlin & London, Europe

“Augmenting with nexRsolve was like having senior in-house developers from Day 1. Their Flutter and Go engineers completely solved our offline telematics sync across 12 Asia-Pacific countries. The 14-day trial gave our board total confidence.”
