AI Solutions That Actually Work in Production

Custom automation, RAG systems, and analytics that turn your data into decisions — not just dashboards.

The Challenge
You have data but no way to act on it at speed. Manual processes eat your team's time, and off-the-shelf AI tools never quite fit your domain.

We solve this with a focused, sprint-based approach — senior engineers who own the outcome from day one.

FAQ

Common Questions

Deep Dive

RAG Pipelines, LLM Integration & AI Automation Services

DevNexus builds production AI systems using Python, LangChain, LlamaIndex, and LangGraph — connected to your real data sources, not just demos. We work with product teams and enterprises who need AI that delivers measurable outcomes: faster workflows, lower manual effort, and decisions backed by real data.

01

RAG Pipeline Development with LangChain & LlamaIndex

We design and build retrieval-augmented generation (RAG) systems that let your teams query internal documents, knowledge bases, and structured data with reliable, grounded answers. Our RAG pipelines use pgvector, Pinecone, or Weaviate for vector search — combined with LangChain or LlamaIndex for orchestration, chunking strategies, and reranking. We include evaluation pipelines from the start so you can measure answer quality, not just ship and hope.

02

LLM Integration with OpenAI, Anthropic & AWS Bedrock

We integrate GPT-4, Claude, Mistral, and AWS Bedrock models into your existing products and workflows via clean, maintainable Python APIs. Integration includes prompt engineering, structured output parsing, fallback logic, rate limiting, and cost tracking. We build evaluation harnesses that measure hallucination rate, latency, and task-specific performance — so you can upgrade models without breaking production.

03

AI Workflow Automation and Document Intelligence

We design AI-powered automations that process documents, extract structured data, classify content, and route work to the right systems or people. Built with Python, FastAPI, and n8n — connected to your CRM, ticketing system, or ERP via REST APIs. Common use cases: automated patient intake processing, invoice extraction, contract review triage, and support ticket classification.

04

AI Analytics and Decision Support Systems

We build AI-enabled analytics products that surface anomalies, predict outcomes, and recommend next-best actions — delivered as dashboards or embedded directly into your SaaS product. Built on Python data pipelines, PostgreSQL, and Next.js frontend — with model monitoring that alerts when prediction quality degrades in production.
