AI Feature Integration into Your App

$40/hr Starting at $500

You have got a working product and you want to add AI to it — without breaking what already works. That is exactly the kind of job you want a senior engineer for, not someone following a tutorial.


I am a Principal Software Engineer (Engineer of the Year 2023) with 6+ years in production systems handling millions of requests. I have integrated payments (Stripe), messaging (Twilio), real-time systems (WebSockets), and multi-vendor OTA APIs at scale. Adding an LLM to your app is the same discipline: clean integration, error handling, sensible cost and latency controls, and code that fits your existing stack.


What I can build into your app:

- AI features via OpenAI, Anthropic (Claude), or open-source models

- Smart search, summarization, classification, chat, or content generation

- Streaming responses, rate limiting, caching, and cost controls built in from the start

- Clean, tested code in your existing framework, with documentation


Demo: https://summit-trails-ai-integration.vercel.app (streaming summarize + auto-tag built into an existing app UI)


Stack: Node.js, Python, Next.js/React, and more. Share your stack and the feature you want, and I will scope it properly before we start.


Background: re-architected a multi-OTA booking engine cutting API/admin response times from 20-30s to under 2s, +30% release velocity via CI/CD. Production integrations across Stripe, Twilio, SendGrid, WebSocket real-time systems.


Milestone-based via SafePay. Clear scope before any quote.
