I integrate Anthropic Claude or OpenAI GPT APIs into your existing web application — production-grade, not demo-grade. 5+ years shipping React + Node systems at Accenture and TCS, plus a live AI SaaS (Chef Claude, chef-claude-peach.vercel.app) I built solo on the Claude API.
What you get:
• Streaming AI responses with proper loading/error states
• Prompt engineering tuned for your specific use case
• Agentic workflows (tool use, multi-turn reasoning, RAG over your docs)
• Rate limiting, retry logic, graceful degradation when the API is down
• Proper auth + API key management (never exposed client-side)
• Monitoring hooks so you can measure what users actually do
Ideal for: chatbots, AI assistants, document Q&A, RAG pipelines, content generators, code assistants, and automation workflows. I've built all of these in production.
Stack I use: React, Next.js, Node.js, Express, TypeScript, Anthropic Claude SDK, OpenAI SDK, Pinecone/pgvector/Weaviate, Redis, Docker, AWS/Vercel.
How I work: share a short brief of what you're building and which model you want (Claude vs GPT) through Guru's messaging, and I'll reply within a day with a rough scope, timeline, and fixed-price or hourly quote.
