You will get an AI SaaS with Stripe Integration by AI Developer

Project details
You will get a fully working AI SaaS product with Stripe billing already wired in, not just a prototype. I'm a full-stack engineer with 7+ years building production apps, and I run an AI-native team with a 100% Job Success score and Top Rated Plus rating on Upwork.
Most AI SaaS ideas stall in the gap between a clever demo and something people can actually pay for. My job is to close that gap. I take your idea and build the whole thing: the AI features at the center, the Stripe subscriptions that turn it into a business, and the essential parts like authentication, a dashboard, and a backend that holds up as users grow.
I work in Next.js, Node.js, and TypeScript on AWS, and integrate models like OpenAI's GPT or Claude depending on what fits your use case. Whether you want a lean MVP to test demand or a launch-ready platform, you get clean code, clear documentation, and something you can actually ship.
Let's turn your concept into a product that earns.

AI Developer / Full Stack Developer & Engineer for AI product end to end
Working with Hassaan and his team was a fantastic experience. They are true experts in AI solutions and full stack development. What stood out most was how Hassaan handled a critical production outage. When our system went down at the worst possible time, he stayed remarkably calm and methodical, diagnosed the issue fast, kept us informed throughout, and had us back online quickly. His grace under pressure earned our complete trust.
extremely recommended, and hiring him again for my other projects also

Full stack implementation of token-based claiming of AWS IoT hardware.
Hassaan and team are true professionals. We have worked with dozens of freelancers on UpWork and the Divescale team are standouts-- well organized without being rigid, very clear communication, apply software development best practices end-to-end, make a conscious effort to continuously develop their team member skills, and deliver high quality solutions quickly. They will be our first call for full stack work in the future.

Your team is burning $50K–$500K a year on work AI should already be doing. I build the systems that reclaim it: I pinpoint the waste, automate it, and ship it to production. Not prototypes, not demos, real systems running 24/7.
I'm an AI Developer and AI-powered Full Stack Engineer with a strong machine learning foundation, and I lead a team that takes extreme ownership of what we ship. As an AI Developer, I take projects from idea to production: AI architecture, AI agents, agentic workflows, and RAG pipelines, grounded in real machine learning rather than wrappers. As a Full Stack and Web Developer, I build the product around them in React, Node, and Python. And as an AWS architect, I deploy and harden everything with observability, security, and cost optimization, so you get an AI system that ships fast and runs reliably in production.
🐾 Pet Health Care System — AI-native OS for vet hospitals; unifies scheduling, records, billing, imaging across 6–12 tools. Targets 40% of a vet's day lost to paperwork, $50K–$100K/yr no-show losses, 8–12% of procedures never invoiced. Built with Next.js, NestJS, PostgreSQL, Python AI, AWS.
🏨 Hotelly — All-in-one hotel ops platform: CRM, billing, tasks + Apple TV (tvOS) in-room entertainment. 70–95% less manual reset effort, 50–80% faster provisioning, 60–90% less admin time. Built with React, React Native, Node.js, PostgreSQL, AWS by AI Developers.
📄 DocuPulse — AI document intelligence inside Excel for finance & compliance teams. Processing 5–10 min → under 1 sec, 94% cost reduction, 88–99% accuracy. Built with React, Node, ElasticSearch, AWS.
🪟 Fenestra — AI order intelligence turning WhatsApp/emails into error-free POs in under 60 sec across 25,000+ SKUs. Live inventory checks, accurate orders before dispatch. Built with Next.js, NestJS, PostgreSQL, LangChain, Claude.
🛒 Smart Shop AI — Ecommerce intelligence unifying Shopify, Google Ads & Meta with a conversational AI analyst. Real-time insights, anomaly alerts, campaign recommendations. Built with NestJS, React, PostgreSQL, LangChain.
✅ AI Agents & Agentic AI: As an AI Developer and agentic AI developer, I design AI agents and multi-agent systems that run agentic workflows across LangGraph, CrewAI, n8n, and Zapier, designed to scale operations without adding headcount.
✅ AI Voice & AI Chatbots: I build voice AI agents and conversational AI on the OpenAI Realtime API, LiveKit, ElevenLabs, Deepgram, and Whisper, plus WhatsApp, Telegram, and web chatbots wired to real business logic.
✅ RAG & LLM Engineering: I build hallucination-resistant RAG pipelines in Python over Pinecone, Weaviate, Qdrant, ChromaDB, LanceDB, and Amazon OpenSearch, using hybrid search, re-ranking, chunking, and embeddings.
✅ AI Orchestration: I orchestrate LLM applications in Python with LangChain, LangGraph, and LlamaIndex, connecting the OpenAI API, Anthropic Claude (Sonnet, Opus, Haiku), AWS Bedrock, and Vertex AI through MCP servers, function calling, and structured outputs.
✅ Machine Learning & Data Science: As a machine learning engineer working alongside data scientists, I take models across the full lifecycle, from data pipelines and feature engineering to training, evaluation, and deployment.
✅ Document Intelligence: I turn documents into answers with PDF parsing, OCR, and document Q&A over knowledge bases and ERP integrations.
✅ Prompt Engineering: I engineer reliable model behavior through system prompt architecture, chain-of-thought, and prompt chaining, then harden it with prompt optimization, evals, and guardrails.
✅ Generative AI Models: I work across GPT-4o, GPT-4 Turbo, o1, and o3, Claude Sonnet, Opus, and Haiku, Gemini 1.5 and 2.0, LLaMA, Mistral, and Whisper, picking the right model for each job.
✅ Full Stack & Web Development: As a full stack developer, web developer, and Python developer, I build full stack apps with React, Next.js, TypeScript, and Tailwind CSS on the front end, and Node.js, NestJS, Express, and Python (FastAPI, Django, Flask) on the back end, including work as an AI website developer and app developer building AI web apps around real product logic.
✅ AWS Architecture & Cloud: As an AWS cloud architect and AWS solutions architect, I handle AWS architecture end to end, deploying on AWS using Lambda, EC2, ECS, EKS, Fargate, S3, RDS, Aurora, DynamoDB, SQS, SNS, EventBridge, CloudFront, API Gateway, VPC, IAM, KMS, WAF, and Secrets Manager. AWS Certified Cloud Practitioner.
✅ No-Code & Workflow Automation: As an Airtable developer, I connect tools like Airtable, n8n, Zapier, and Make into automated workflows that move data and trigger actions automatically.
✅ Integrations: I connect products to the tools businesses already run, including Stripe, HubSpot, Salesforce, NetSuite, Plaid, Yodlee, HL7/FHIR, Slack, MS Teams, and WebRTC.
