You will get OpenAI API integrated into your existing SaaS product or web application

Project details
You have a working product. Your users want AI features, smarter search, auto-fill, summarization, suggestions, or a chat interface, and your team doesn't have the LLM experience to ship it cleanly. You will get OpenAI API (or Claude API) integrated into your existing application as a new feature endpoint, UI component, or background pipeline. Works with SvelteKit, Next.js, React, Vue, or Node.js. Production-grade: rate limiting, error handling, cost controls, and logging included.
Common use cases: text summarization, smart auto-complete, document Q&A, AI-generated reports, sentiment tagging, conversational search, and AI onboarding flows.
Message me before ordering so I can review your stack and recommend the best AI workflow for your product.

Job Success
Doha, Qatar - 2:14 am local time
Over 10 years of full-stack development, 70+ projects, and 5,000+ billable hours on Upwork with 5-star ratings across the board. My recent work focuses heavily on LLM integration, RAG systems, and agentic AI workflows built into SaaS products that businesses depend on daily.
What I build:
- AI-Powered SaaS Applications: LLM-driven features embedded into production software using LangChain, LangGraph, Vercel AI SDK, and OpenAI API. I've built AI personalization engines, automated document processing systems, conversational interfaces, and agentic workflows that handle multi-step business logic without hand-holding.
- Full-Stack Product Development: SvelteKit, React, Next.js, Vue.js, Node.js, TypeScript. I build the entire stack from frontend through API layer to database. Multi-tenant architectures, authentication systems, complex transactional flows. I've shipped booking platforms handling millions of users and marketplace apps with real money moving through them.
- Backend & Infrastructure: Supabase, PostgreSQL, MongoDB, AWS. API design and integration is a core strength. Most of my projects are API-heavy systems connecting multiple services, third-party platforms, and AI pipelines into a single reliable product.
Industry experience across fintech, e-commerce, healthcare, transportation, and HR systems. I've delivered enterprise HRMS platforms, fintech dashboards, IoT analytics systems, and SaaS MVPs that went on to raise funding.
What clients have said:
"The best developer is the one you need very few revisions/fixes." That's how I work. Clean code, clear milestones, and a finished product that doesn't need rework.
Available for projects and retainer engagements. Happy to jump on a call to scope your build
