I will develop a custom business system or multi tenant saas platform


About this gig
I design and build systems that solve a real business problem, from architecture to deployment.
I am the founder and solo developer of Jastiper, a multi tenant SaaS platform for personal shopper businesses that I built and operate myself: multi tenant architecture, live commerce with WebRTC, payment gateway integration with webhook and reconciliation, logistics integration, and a wallet system for seller payouts. 789 commits, 157 automated tests, running on self hosted infrastructure.
I can help you with:
Multi tenant SaaS architecture (isolated data per client, multi domain routing)
Payment gateway integration with webhook handling and reconciliation
Business logic design, turning your business rules into consistent system rules
Wallet or ledger systems for marketplaces and platforms
Admin dashboards and reporting
System architecture consulting if you already have a team and need a technical review
This is a bigger scope service, so please message me with your requirements first. I will confirm feasibility and propose a custom package if your project does not fit the tiers below.
