    ...admin-friendly back-office. A clean, modern interface is a must, so thoughtful use of CSS frameworks (Tailwind, Bootstrap, or a bespoke solution) and component libraries is welcome as long as the final look remains lightweight and on-brand. Functionally, the app must: • handle secure user sessions with best-practice authentication and encrypted data at rest and in transit; • connect to a relational or NoSQL database for products, orders, and user data; • deliver sub-second page transitions through optimized queries, caching, and code splitting; • pass a pre-delivery test suite that covers critical paths such as add-to-cart, payment callback, and order confirmation. Clean, well-documented code is non-negotiable; comments, meaningful commit messages, a...

    I want to bring a couch-co-op party experience to phones and tablets: four friends sharing one screen, jumping straight into quick-fire mini-games such as tank duels, bumper-car clashes, endless runners and frantic tap races. The project must run smoothly in both 2D and lightweight 3D on Android and iOS, entirely offline, with everyone interacting by tapping their own corner of the screen. Scope of work • Build the core lobby, player-join flow and round-rotation logic in Unity (C#). • Create four fully playable mini-games, each ending in a scoreboard that feeds back into an overall session tally. • Implement a single-touch control zone for each player, keeping inputs intuitive and latency-free. • Integrate AdMob (rewarded, interstitial and banner placements) so ...

    My well-loved couch cover is 100 % cotton and is starting to show its age. Several small tears and a couple of larger holes have appeared, and I’d like them neatly mended so the repairs blend with the existing weave and colour. While you are working on it, I also want the high-stress areas—especially the corners and seat panels—reinforced from the inside so the fabric holds up to daily use. What I need from you: • Invisible or near-invisible stitching that closes every tear or hole without puckering the cotton. • Internal reinforcement (backing fabric, interfacing, or similar) placed where the cover experiences the most tension. • A final press so the cover returns to me ready to slip straight back onto the couch. Thread and any backin...
