I have an Android Studio project that needs some spring-cleaning before we add a small new feature. First, the housekeeping: • strip out any dead or unused classes, methods, and resources • refactor what remains so the codebase is readable, well-named, and lint-warning free • resolve a couple of known crashes and UI glitches Once that baseline is solid, I’d like a new dropdown on the main screen. It only has to show a static list that ships with the app—no dynamic filtering or server fetches right now—but please wire it so it can be extended easily later. The app is built with Kotlin (with a few legacy Java files), Gradle 8, minSdk 24. I’ll provide Git access and notes on the bugs I’m seeing. Deliverables • Clean compile wi...

I need an Excel-based workbook that lets me type a scaffold tag in once and have everything else spring to life automatically. As soon as I enter or edit a tag, the file must: • Pull the associated material list and roll the counts into overall yard balances. • Issue a unique, sequential tag number if one is not already assigned. • Start a 28-day billing clock, post the recurring charges on schedule, and stop that clock the moment I mark the tag as dismantled. • Produce the final invoice for that tag, zero it out of active inventory, and leave a clean audit trail. All yard totals, billing summaries, and aging reports should stay current without manual refreshes. I also want a simple dashboard that shows what is on rent, what is due for billing this cycle, and w...

My multi-app food-delivery platform (React Native front ends, Java & Spring Boot backend) already runs smoothly for customers, restaurants, delivery partners and admins. I now need a secure hand-over confirmation flow: 1. When the delivery partner clicks on GET DELIVERY LOCATION, the Customer app must auto-generate a single-use OTP/Pin. 2. The code stays valid for exactly 30 minutes (time-based expiry) and the customer can trigger a fresh code immediately if something goes wrong. 3. The Delivery Partner app prompts for this code on arrival; on successful match the backend records “delivered” and releases any pending status updates to the Restaurant and Admin apps. SECOND PART: After confirmation for order from Restaurant app, all devices of DELIVERY Partner get...
I already have a complete wrist-watch case model; only the lugs need attention. Visually they appear a bit too sharp and too square for the overall aesthetic, so I want their profile softened and made noticeably more rounded with a compound curve toward the end of the lugs and the side of the lugs while every critical dimension—spring-bar position, strap width, case diameter—remains untouched. An additional position for a second spring bar will need added. there is an overhang above the stap end that will to be chamfered on the top edge and the bottom edge of the overhang to prevent damage to the leather strap to be installed after manufacturing. A clean, production-ready update is what I’m after, not a wholesale redesign. If you work comfortably in SolidW...
I’m migrating an older Java backend—built on legacy Spring and Hibernate—into a fresh Spring Boot 3 project so the stack is fully modern and future-proof. The focus is code refactoring: untangling dated patterns, replacing XML configuration with annotations, adopting Spring Data JPA, and cleaning up any deprecated API usage. No new features are needed right now; the goal is pure code modernization. You’ll receive a private Git repo containing the current application and a lightweight skeleton for the new one. Work incrementally, push frequent commits, and raise pull requests so the migration stays transparent and reviewable. GitHub Actions is already wired, so every PR should keep the build green. Deliverables • A runnable Spring B...
