You will get Claude or OpenAI API streaming into your SvelteKit or Next.js app
Top Rated
Project details
Most AI integrations are bolted onto products as external services, separate Python microservices, inconsistent APIs, and UI layers that don’t reflect real-time model behavior. This project delivers LLM integration as a native part of your SvelteKit or Next.js application, fully built in TypeScript from backend streaming to frontend UI.
You will get production-ready integration of Claude API, OpenAI API, or both, including Server-Sent Events streaming, tool/function calling with typed schemas, multi-turn conversation memory, and structured JSON outputs. The UI is built to mirror model execution in real time, not just display responses after generation.
Delivered with enterprise-grade architecture based on 7+ years of production TypeScript systems and real SaaS builds, including Claude + internal system integration, OpenAI speech-to-text pipelines, and long-term SvelteKit production deployments.
Best suited for SaaS products that need embedded AI features without adding external dependencies or maintenance overhead.
Send your requirements and I will map the exact architecture for your AI integration inside your existing app.

AI Full stack developer needed for Claude ai, Openclaw integration with internal system
Outstanding experience working with Jam.
He brings hands-on expertise as an AI-driven Full Stack Developer, seamlessly handling Claude AI and OpenClaw integration with internal systems. His technical depth across both frontend and backend made the entire process smooth and efficient. He communicated clearly throughout, delivered on time, and went above and beyond to ensure everything worked perfectly.
Highly recommend him for any AI integration or full stack development projects.

Full stack developer needed for API integration with our existing app SvelteKIT and FASTAPIs
Great pleasure of working with Jam!
My Full-stack development project involving API integration for our existing app built with SvelteKit, Typescript, TailwindCSS and back-end with FastAPI. He Dockerized the app, deployed it to Vercel, added CI/CD & added documentation.
He has strong skill sets in full-stack, front-to-back development, CI/CD & AI driven APIs integration & is easy to work with due to his communication excellency and on time response.
I'll hire him again soon!

Integration of Google Speech-to-Text and OpenAI API using Svelte 5, SvelteKIT
Jam did an excellent job integrating Google Speech-to-Text and OpenAI API with Svelte 5 and SvelteKIT. Their work was seamless, efficient, and well-structured, showcasing strong technical skills. Highly recommended for Front-end development with Svelte, SvelteKIT and API integrations, typescript based projects!
His communication throughout the project was outstanding, keeping me informed and join calls, which was crucial for the project's success. The code quality was top-notch, adhering to best practices and making future maintenance straightforward.

Most developers treat AI integration as a separate service bolted onto the side of a product. I build it as a first-class part of your application, streaming responses, tool-calling, Supabase vector search, typed inputs and outputs, and a UI that actually reflects what the model is doing in real time.
After 7+ years building production full-stack systems across SvelteKit, React, Node.js, Golang, and Rust, I've learned that the hardest part of AI integration isn't the LLM call , it's making it reliable, observable, and maintainable inside a real codebase. That's the part I specialise in.
🔧 𝐖𝐡𝐚𝐭 𝐈 𝐛𝐮𝐢𝐥𝐝
- 𝐋𝐋𝐌 𝐀𝐏𝐈 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧: Claude, OpenAI, and Gemini integrated into your SvelteKit or Next.js app. Streaming via Server-Sent Events, function/tool-calling with typed schemas, multi-turn conversations with memory, structured JSON outputs. TypeScript-first, no Python dependency.
- 𝐑𝐀𝐆 & 𝐊𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞 𝐒𝐲𝐬𝐭𝐞𝐦𝐬: Document ingestion, embeddings, and semantic search using Supabase pgvector, all in TypeScript. Build document Q&A, internal knowledge bases, or AI search on top of your existing Supabase database without adding a separate vector infrastructure.
- 𝐑𝐞𝐚𝐥-𝐓𝐢𝐦𝐞 𝐀𝐈 𝐈𝐧𝐭𝐞𝐫𝐟𝐚𝐜𝐞𝐬 𝐢𝐧 𝐒𝐯𝐞𝐥𝐭𝐞𝐊𝐢𝐭: Svelte 5 runes, SSE streaming, reactive AI state, live token output. SvelteKit's native reactivity makes it one of the best frameworks for AI UIs, faster to build, lighter to ship, and more maintainable than React for streaming use cases.
- 𝐇𝐢𝐠𝐡-𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞 𝐀𝐈 𝐁𝐚𝐜𝐤𝐞𝐧𝐝𝐬 𝐢𝐧 𝐆𝐨𝐥𝐚𝐧𝐠 & 𝐑𝐮𝐬𝐭: When your AI pipeline needs throughput, embedding jobs, async agent task queues, concurrent API orchestration. I build it in Golang or Rust. Fast, efficient, and built to handle production load without Python's GIL limitations.
- 𝐀𝐈-𝐏𝐨𝐰𝐞𝐫𝐞𝐝 𝐒𝐚𝐚𝐒 𝐌𝐕𝐏𝐬: 𝐅𝐮𝐥𝐥-𝐬𝐭𝐚𝐜𝐤 𝐝𝐞𝐥𝐢𝐯𝐞𝐫𝐲: SvelteKit or Next.js frontend, Node.js or Golang backend, Supabase database with pgvector, LLM integration, Stripe billing, Vercel or Railway deployment, and documentation your team can maintain. Idea to deployed product in 2–4 weeks.
