Yasir KhanSolutions Architect
Solutions Architect · AI Systems · Full Stack

Your AI-built SaaS, made production-ready.

I take AI prototypes and AI-assisted SaaS products into secure, reliable, monitored systems: AI agents, RAG assistants, Voice AI, API integrations and the full stack software around them. I learned to build software in fintech, where one mistake costs real money. I bring that same standard to your product.

The problem

It works in the demo. It has to work on Monday morning.

SaaS founders and product teams

The product was built fast. Now it has to hold up.

You shipped quickly with AI tools or added AI features, and now the product breaks under real users, does not scale, or is not safe to put in front of paying customers.

  • No one on the team can take the AI feature past the prototype
  • Errors fail silently and nobody owns the fix
  • Security, data and payments need a grown-up architecture
Growing businesses

Your team loses hours every week to manual work.

Data moves by hand between email, forms, the CRM and spreadsheets. The same customer questions get answered again and again, and new leads wait hours for a reply.

  • No-code automations that do not reach your real systems
  • AI tools that nobody connected, monitored or maintained
  • Leads and customers waiting on a person to copy and paste
What I build

The whole system, not just the workflow.

I am a Solutions Architect with a full stack background. I take it from process mapping and architecture to deployment on AWS, Google Cloud or Azure, with logging, retries and alerts so it keeps working after handover.

AI agents

Agents that qualify leads, handle customer support and follow up, connected to the CRM, email and calendar you already use, and that hand over to a person when they should.

RAG assistants

Assistants that answer from your own documents and data, with sources, access rules and answers your team can check.

Voice AI

Voice agents for inbound and outbound calls, connected to the calendar, CRM and tools your team already works in.

LLM and API integrations

OpenAI, Claude and Gemini with tool calling and webhooks, wired into CRMs, payment providers, calendars and internal tools.

Full stack SaaS

Python and FastAPI or Node.js backends, PostgreSQL, Supabase and Redis, and Next.js dashboards so you can see what the automation is doing.

Production hardening

Stability and performance work on live SaaS products: Docker, CI/CD, monitoring, retries and alerts, so releases are faster and safer.

Selected work

Platforms where one mistake costs real money.
