Project details
ou have an idea for an AI tool, but a Python script in a notebook isn't a product. You need a secure, scalable, and monetizable platform that users can actually log into.
I am an AI SaaS Architect. I specialize in building "Sovereign AI" platformsproduction-ready web applications where you own the data, the code, and the customers.
I don't use no-code builders. I build custom, high-performance engines using the modern industry standard: Next.js & Supabase.
My Tech Stack:
Frontend: Next.js 14 (App Router), React, Tailwind CSS, ShadcnUI (for beautiful, modern design).
Backend & DB: Supabase (PostgreSQL, Authentication, Real-time updates).
AI Logic: OpenAI GPT-4o, LangChain, or Custom Python Backends (FastAPI).
Payments: Stripe Integration (Subscriptions & One-time payments).
What You Get:
Authentication: Secure Login/Signup (Email, Google, etc.).
Database Architecture: Properly structured SQL tables for users, chats, and data.
AI Integration: Whether it's a Chatbot, an Image Generator, or a Text Analyzer, I wrap your model in a professional UI.
Monetization (Premium): Paywalls, tiered subscriptions (Free vs. Pro), and usage limits.

AI Customer Support Agent for RAG SaaS
We originally set out to get a simple AI support assistant trained on our documentation, but most of what we saw from freelancers were just basic chatbot setups.
What we ended up with was something on a completely different level — a full SaaS product.
It wasn’t just a bot. The system came with a proper knowledge base ingestion process, a solid AI search and retrieval pipeline, a clean customer-facing chat widget, and a well-built admin dashboard with analytics.
Everything feels thoughtfully designed and built to scale. The UI doesn’t come across like a quick prototype — it feels like a real, production-ready product.
Within the first month alone, our support tickets dropped by 60%.
If you’re looking for someone who genuinely understands both AI systems and how to turn them into real, usable products, he’s a great choice.

AI Document Intelligence System Development for Legal Firm
We hired this developer to build an AI document intelligence platform for our legal firm, and the results exceeded expectations. He delivered a full production-grade system that lets our lawyers instantly search thousands of contracts using natural language. The clean Next.js dashboard and lightning-fast FastAPI + vector search backend make it incredibly efficient. His strong system architecture and scalable design now save our team 20+ hours every week. Highly recommended for building real AI systems.
About Sasanka
AI Systems Architect| RAG, Agents, WebApps, Data Automation&Com:vision
Katugastota, Sri Lanka - 3:57 pm local time
I help businesses turn manual workflows, messy data, and AI ideas into reliable web applications, automation systems, and intelligent tools that work in the real world.
You are likely here because:
• You need a custom AI tool, RAG chatbot, or autonomous agent integrated into a real SaaS or internal web app.
• You have a manual workflow that needs end-to-end automation.
• You need large-scale data extraction, monitoring, or web automation built for reliability.
• You want computer vision, document processing, or machine learning integrated into a production system.
• You need someone who understands the full stack: data extraction → AI processing → backend architecture → frontend UI.
How I Am Different
Most freelancers are either “Python developers,” “React developers,” or “AI prompt engineers.” I bridge the full system.
I design and build complete solutions across:
• AI & LLM Systems: RAG pipelines, AI agents, OpenAI integrations, LangChain, LlamaIndex, vector databases, tool-use agents.
• Web Applications: Next.js, React, TypeScript, Tailwind, Supabase, FastAPI, Stripe, dashboards, admin panels, SaaS platforms.
• Data Automation: Web scraping, browser automation, data pipelines, monitoring systems, API integrations, scheduled workflows.
• Machine Learning & Vision: YOLOv8, PyTorch, OpenCV, object detection, image processing, synthetic data pipelines.
• Infrastructure: Docker, AWS, Vercel, Redis queues, scalable backend systems, automation workflows with n8n and Make.
What I Build
I can help you build:
• Production RAG chatbots trained on your internal documents, websites, PDFs, or knowledge base.
• AI agents that take actions, use tools, monitor data, and automate business workflows.
• SaaS platforms with AI features, payments, authentication, dashboards, and backend logic.
• Data extraction and monitoring systems for products, leads, jobs, real estate, pricing, or market intelligence.
• Computer vision systems for defect detection, object tracking, visual automation, or image-based workflows.
• End-to-end automation replacing repetitive manual work across operations, research, sales, and support.
Real-World Results
• Replaced manual workflows equivalent to 3 full-time employees, saving approximately $180K/year.
• Built AI systems that reduced documentation search time by 90% across 10K+ pages.
• Engineered RAG pipelines using hybrid search to significantly reduce hallucinations and improve accuracy.
• Created automated monitoring systems for 50K+ SKUs with real-time alerting.
• Built synthetic data pipelines capable of generating 50K+ labeled images/hour for computer vision training.
• Developed AI monitoring systems processing 10,000+ jobs/day in real time.

The Type of Clients I Work Best With
I work best with founders, agencies, SaaS teams, and businesses that want to build long-term technical assets — not temporary scripts.
Whether you need an AI-powered SaaS, a custom automation platform, a data extraction system, or a machine learning solution, I can help you design, build, and deploy it properly.
Let’s build something reliable, scalable, and useful.
