SellAnyBiz

The Challenge

Buying or selling a business is one of the largest transactions most people make, and much of it still runs on scattered listings, manual matching and email. SellAnyBiz brings buyers, sellers, brokers and advisors onto one platform and uses AI to take on parts of that work.

The Solution

SellAnyBiz is a production platform built by a team. I contributed as a Full-Stack Developer from December 2025, developing and maintaining features across the frontend and backend within the existing codebase.

What I contributed to

My contributions span listings and the listing builder, secure data rooms, document workflows and AI-assisted workflows, including AI-assisted generation. On the backend that includes APIs, authorization and permissions, database access and caching; on the frontend, real-time user experiences.

AI chat and long-running tasks

I resolved complex state-management issues in AI chat flows and designed clearer UX for long-running AI tasks.

Stack

Next.js, React and TypeScript on the frontend; ElysiaJS on Bun for the API; Supabase/PostgreSQL for data; Redis for caching; and LLM integrations through the Vercel AI SDK and OpenAI.

The codebase is private, so there's no repository link, but the platform is public at sellanybiz.com.
