RAG System Development
We build retrieval-augmented generation over your documents, databases, and APIs with hybrid search, reranking, and citation-backed answers. Every system ships with an evaluation harness measuring accuracy and groundedness.
Next-gen Talent
Hire Gen AI Engineers
Hire Gen AI engineers who build LLM-powered copilots, agents, and RAG systems your business can actually trust in production.
Anyone can call an LLM API; very few teams can ship generative AI that is accurate, safe, and cost-controlled at scale. Devlex Infotech Gen AI engineers build retrieval-augmented generation systems, multi-agent workflows, and fine-tuned models with rigorous evaluation pipelines - so hallucination rates are measured, latency is budgeted, and token costs do not surprise your CFO.
Our Gen AI practice has delivered customer-support copilots that deflect 45% of tickets, contract-analysis tools that cut legal review time by 60%, and internal knowledge assistants for enterprises across 5+ countries. Hire a dedicated Gen AI engineer from $2,600/month - vetted profiles in 24-48 hours, NDA-first.
- Expertise in GPT-4, Claude & open-source LLMs
- Production RAG with vector search & evaluation
- Multi-agent systems with LangGraph & CrewAI
- LLMOps: cost control, guardrails & monitoring

What They Can Do
Our Gen AI Engineers Expertise
AI Agents & Workflow Automation
Multi-step agents that research, draft, validate, and act across your tools using LangGraph, CrewAI, and function calling. Human-in-the-loop checkpoints keep autonomous workflows safe and auditable.
Custom Copilots & Chat Assistants
Domain-trained assistants for support, sales, HR, and engineering teams embedded directly in your product or Slack. We tune prompts, retrieval, and guardrails until deflection and CSAT targets are met.
LLM Fine-tuning & Model Selection
When prompting hits its ceiling, we fine-tune open-source models like Llama and Mistral with LoRA on your data, often cutting inference costs 70% versus frontier APIs. Model selection is benchmarked, never guessed.
Enterprise LLMOps
Token cost dashboards, prompt versioning, regression evals, PII redaction, and content guardrails built into your pipeline. You get observability over every generation in production.
Generative AI Product Strategy
We run discovery workshops that separate viable Gen AI use cases from hype, then prototype the top candidates in 2-3 week sprints. You invest in what demonstrably works.

“Devlex rebuilt our patient scheduling platform from a legacy PHP system into a HIPAA-compliant React and Node.js application. No-show rates dropped 27% within three months of launch, and their team caught compliance gaps our own auditors had missed.”
“They delivered our Flutter app for iOS and Android in 14 weeks, exactly on the quoted budget. App Store rating sits at 4.8 and the weekly sprint demos meant there was never a single surprise.”
“We hired a dedicated team of five from Devlex to build our property management portal, and eighteen months later they still feel like our own employees. Releases ship every two weeks and platform uptime has held at 99.95%.”
