Job Success
Surat, India - 6:46 pm local time
I help startups and businesses build AI-powered applications, backend systems, and scalable web platforms that are stable, fast, and production-ready, not just MVPs that break later.
Most clients reach out to me when they:
-want to build an AI product but don’t know the best architecture
-need a chatbot connected to their own data or workflows
-want to automate repetitive business processes
-need to fix slow APIs or backend performance issues
-already have a product and want to scale it properly
I work across both AI engineering and full-stack development, so you don’t have to manage separate frontend, backend, and AI freelancers to get things done.
⭐ What I have delivered for clients:
-Built AI chatbot systems that automated 60–80% of customer interactions using OpenAI APIs and RAG workflows
-Improved application and API performance by 25–50% through backend and database optimization
-Developed SaaS platforms used by thousands of active users with scalable architecture
-Built workflow automation systems that saved teams 10–20+ hours per week
-Integrated AI features into existing applications without disrupting production systems
What I usually work on:
-AI chatbot & AI agent development
-OpenAI / Claude integrations
-RAG pipelines & custom knowledge bases
-Workflow automation using n8n
-SaaS applications & internal tools
-REST APIs & backend architecture
-Full-stack applications using React, Next.js, and Node.js
Tech I use regularly:
-AI & Automation: OpenAI, Claude, LangChain, n8n, RAG pipelines
-Frontend: React, Next.js, TypeScript
-Backend: Node.js, NestJS, Express, FastAPI
-Cloud & Databases: AWS, PostgreSQL, MongoDB, MySQL, Docker
Background:
I’m a Top Rated freelancer with:
-3,300+ hours worked
-$49K+ earned on Upwork
-100% Job Success Score
I have worked with clients across SaaS, fintech, healthcare, e-commerce, and internal business platforms.
How I work:
I usually start by understanding the actual business problem first, not just the feature request.
From there, I help structure the architecture, choose the right approach, and build systems that are maintainable, scalable, and reliable long-term.
You’ll get clear communication, regular updates, and realistic timelines throughout the project.
Let’s talk:
If you’re planning to build an AI product, automate workflows, or improve an existing system, send me a message or invite me to your project.
I’ll review your requirements and give honest feedback on the best approach, timeline, and scope before we move forward.
Best Regards,
Swapnil.
