...or edit items and review every order. Because inventory accuracy is critical, I expect strong protection against overselling under heavy traffic—database transactions or row-level locking are fine so long as stock counts stay correct. Whichever approach you choose, explain the strategy and make sure it scales. Stripe will handle payments, but I’m open to layering in other gateways later as long as automatic refunds and bank-level reconciliation remain intact. I prefer the front-end to be built with Angular; for the native-like mobile experience you can reach for Ionic, Capacitor or another Angular-friendly stack. The back-end language and database are up to you as long as they permit the transaction/locking model described above. Once the MVP is solid, I ma...

I’m equally comfortable on WhatsApp, Zoom, or Teams and will share a running task list there. I’ll supply all graphics; you focus on code, layout, and any micro-interactions that need smoot...

You’ll begin by profiling the pages to pinpoint what’s dragging them down, whether that’s heavy scripts, oversized images, inefficient queries, or a missing cache layer.

Within each sheet I still want the usual Excel conveniences (filters, basic sorting) so I can slice the data any way I like. You’ll have access to the relevant email folders plus a spreadsheet of my LinkedIn profile links to...

I’m building a dedicated app that lets our in-house pharmacists run the entire medication cycle from a single screen. The core features I need are prescription management that pulls validated orders from our HIS, real-time medicine inventory that syncs with the store database, and patient order tracking so a pharmacist can see where each request sits in the queue at any moment. Only pharmacists will log in for this first release, so the interface can stay streamlined around their daily workflow—receiving the electronic script, checking stock, adjusting quantities, and marking the hand-over or ward dispatch as complete. Later versions may open limited panels for doctors or patients, but that is outside the current scope. I’m comfortable with any modern cross-platf...

I want a lightweight, single-purpose iOS application that lets me capture, edit, and browse a customer database on my iPhone. The flow is straightforward: I open the app, tap “Add Customer,” fill in a few text fields (name, phone, email, notes), and save. I also need a basic search so I can quickly pull up an existing record and make changes. I’m happy with native Swift and either Core Data or SQLite under the hood—whatever you feel is faster for a clean, maintainable codebase.

I’m ready to turn my business concept into a fully functioning web platform that serves both as our public-facing site and the backbone of a software product we will sell online.
