Project details
Elevate your software application by embedding state-of-the-art artificial intelligence directly into your existing infrastructure. I specialize in building custom backend integrations and clean API connections using the world’s leading large language models, including OpenAI's GPT, Anthropic's Claude, Google's Gemini, and DeepSeek.
From straightforward chat interfaces to deeply integrated multi-model systems, I deliver highly responsive, production-ready code tailored to your exact business specifications.
What this project includes:
1. Multi-Model Integration: Seamless implementation of OpenAI, Claude, Gemini, or DeepSeek API endpoints into your application stack.
2. Advanced Prompt Engineering: Designing system instructions, context allocation, and parameters for predictable, high-quality responses.
3. Structured Outputs & Tool Calling: Forcing models to return clean JSON data arrays or trigger external system APIs based on user intent.
4. RAG & Context Management: Connecting vector databases to let your preferred model retrieve data from custom internal documents.
Let's build your AI features! Reach out with your current tech stack to get started.

Hi there!👋 I'm Vipin, a Full Stack Developer and AI Integration Specialist with 12+ years of experience building web and mobile products that actually hold up under real-world pressure. My core stack is Laravel, React, Vue.js, Node.js, and Flutter — and lately I've been integrating AI (OpenAI, LLMs, RAG pipelines) into products where it genuinely moves the needle.
My work goes beyond writing code. I treat every project as a product — thinking about architecture, business logic, and what will actually help you grow. I've shipped SaaS platforms, enterprise cloud Apps, and AI-powered tools & automation for clients across industries.
Need a complex backend API? A SaaS platform with multi-tenancy and billing? A cross-platform mobile app alongside a web dashboard? I work across the full product — not just one piece of it. That end-to-end ownership is what most clients come back for.
With over 565+ successfully completed contracts on Upwork, a flawless 100% Job Success Score, and Top Rated status, I don't just write code—I design scalable digital infrastructure that solves real business problems.
Whether you need to build a complex custom web platform from scratch or integrate advanced AI workflows into your existing setup, my team at Limenzy Technologies and I bridge the gap between heavy engineering and business strategy.
What I Deliver:
âś” End-to-end full-stack development
âś” Custom solutions tailored to your business needs
