    I need a small, streamlined website that lets customers create personalised gifts in just a few clicks and then send their confirmed order to my WhatsApp—no online payment for now. Here’s the flow I have in mind: • Visitors land on a single link and immediately see a clean grid of categories such as Birthday Frames, Chocolates, Mugs, Keychains and any others we later add. • Opening a category reveals roughly 20–30 ready-made templates. • After choosing a template, the customer uploads a photo, types a short message or name, and sees a real-time preview. • Clicking “Confirm Order” should package the template ID, customer image, entered text and contact details into a WhatsApp message (pre-filled via or the Business API) that pops ope...

    I’m running a 14-day closed test on Google Play and need exactly twelve unique Android users onboarded through my invite link. You’ll share each tester’s Gmail address so I can whitelist them. They must be from real devices. Here’s the flow I have in mind: once you’ve assembled the group, send a joint introduction email—copying me—so I can distribute the invite. Testers simply need to accept the invitation, install the app, and keep it on their phones for the full two-week period. There are no demographic or location requirements; any Android smartphone user is acceptable. Verification is straightforward. On day 1 collect an installation screenshot from every tester, and on day 14 capture a fresh “still installed” screenshot. If anyo...

    I have a fully finished Android game that is ready to ship to Google Play.

The build itself is final, so no code changes or feature tweaks are expected right now, and I’m not looking for extended ASO work; the focus is on smooth publishing and reliable upkeep once it is in the store.

    I built this gift shop interface using React, and it turned out pretty user-friendly I suppose. The whole thing focuses on showing gifts in a simple way, like products with pictures and names right there on cards. Vite helped a lot with making development quick, and the pages load fast too. I did not expect it to be that smooth at first. Components are the main setup, you know, stuff like the navbar at the top, then the home page, and separate ones for products. It displays a bunch of gifts dynamically, pulling them in without much hassle. Each product card has an image, the name, and some details below it. I used React hooks, mainly useState, to handle the state, which keeps things organized I think. Styling came from CSS, and I aimed for it to work on desktop or mobile, adjusting s...
