I will build a production ready backend or full stack web app
Saif
About this gig
Most B2B products need the same foundation: a backend that handles auth and permissions correctly, a database schema that won't need rewriting in six months, and if it's a business tool, an interface someone can actually operate.
I build that end-to-end in TypeScript. Next.js server actions and route handlers, Drizzle and PostgreSQL underneath, structured so your team can extend it rather than work around it.
WHAT YOU GET
- Clean module structure, ready for your team to build on
- PostgreSQL schema with reversible, re-runnable migrations
- Authentication with roles and per-user permissions
- Optional multi-tenancy, isolation enforced by foreign key, not convention
- Optional admin dashboard wired to the backend
- Docker Compose, so it runs on your own server in one command
- Full source in your repository, plus a runbook and recorded walkthrough
- Two weeks of post-delivery support
I've built this stack in production for a self-hosted multi-tenant ERP with a pluggable module system covering accounting, inventory and supply.
Message me your entity list before ordering, and I'll confirm which package fits.

Hi, I'm Saif
I build the software businesses actually run on: ERP, POS, inventory and logistics platforms. Not marketing sites.
I co-founded a two-person software studio and have shipped a multi-tenant restaurant POS with an offline-first sync engine, a self-hosted ERP with pluggable accounting and inventory modules, a delivery logistics platform with a React Native rider app, and a headless Shopify storefront for a climate tech company.
Message me before ordering, and I'll tell you honestly whether I'm the right fit.

FAQ
Which package do I need?
It depends on how many things your system manages. Under 5 fits Basic. Up to 12, with multiple client organisations sharing one deployment, fits Standard. Add an admin dashboard, and that's Premium. Message me your list first, and I'll confirm the fit before you order.
Do I get the source code?
Yes, on every package. You get the full repository, and it's yours, with no lock-in, no licence key and no per-seat fee. The runbook and recorded walkthrough mean your team or a future developer can pick it up without coming back to me.
What does multi-tenancy mean here?
One deployment serves multiple separate client organisations, with every query automatically scoped so no one sees another organisation's data. It's enforced at the request level, not left to individual queries. Expensive to retrofit later, so worth deciding early.
Can you work with my existing database or API?
Usually yes. Send me your schema or API documentation, and I'll confirm before you order. Integrating with an existing system sometimes changes which package fits, so it's worth checking with me first rather than after.
What if my project needs more than the package includes?
I tell you before I start, not halfway through. Once you send requirements, I confirm what's in scope, so you know upfront if something needs a bigger package. Extras cover additional entities, dashboard screens and deployment setup.
