I need a developer who can put together a simple, static website in Java for my new packaged drinking-water venture. The visual direction is already set: a classic, elegant look that reflects purity and trust.

I’m looking for a single partner who can take my concept from idea to launch on two fronts: a fully-featured Android application and its companion website. Everything should share one clean, secure backend so updates roll out smoothly across both properties.

On the web side, I need a modern, responsive site that mirrors the app’s core functions and brand style. Feel free to recommend the stack—React, Vue, Laravel, Django, or another framework you’re confident will scale. To keep things clear, here’s what I expect at hand-off: • Production-ready website on my hosting • Signed Android APK live ...

I’d like a self-contained, Maven-driven demo that shows how a Wildfly 20 Java servlet can talk to three separate mobile authenticators—Microsoft Authenticator, Google Authenticator and Duo Authenticator—and report back the outcome of each challenge. Scope • Focus exclusively on “second-factor” calls: how the servlet initiates a push / TOTP / Duo prompt (the “sending signal” part) and how it parses the success, timeout or failure response that comes back (“receiving results”). • No UI polish is necessary; a simple JSP or REST endpoint that prints JSON or plain text is fine as long as the code flow is clear. • Keep the sample lean but complete: working source, config files, and any required libraries or...

I need a straightforward CNC program that will cut a clean 12-inch diameter circle from wood that is 3/8" thick on my router. Accuracy at the finished edge is important, so the toolpath must compensate for the bit diameter and leave a smooth perimeter ready for minimal sanding. Please generate and supply: • A ready-to-run G-code file compatible with a standard CNC router controller (GRBL or Mach3 both work here). • A matching design file or DXF so I can verify dimensions before running. • Notes on the cutter size you assumed, plus recommended spindle speed, feed rate, and step-down for a safe, splinter-free pass. That’s the entire job—once the circle drops cleanly from the spoilboard, we’re done.

Core scope • One primary section focused on Product Information, because the site’s main job is to present the services my startup offers. • Each service page must carry two clear elements: a concise service description and transparent pricing information. That content will be ready for you in a document; your task is to integrate it cleanly. Technical expectations • Java stack only—Spring Boot, Jakarta EE, or a JSP/Servlet approach is fine as long as t...

I maintain two production-...criteria 1. Every bug on the supplied list is resolved and verified on at least Android 8–14 emulators or devices. 2.

I’m building a desktop-side utility that can sit between the Chinese version of WeChat and the network, automatically capturing every request a Mini Program makes, parsing the traffic, and then replaying or altering that traffic on demand. The workflow must be almost hands-free: once the script is started, it should watch the connection, log what it sees, and let me feed back custom payloads for instant, programmatic re-submission. Target environment — The first release has to run on Windows. If you can keep the code portable enough for a later macOS or Linux build, that is a plus, but Windows support is non-negotiable. — Headless execution is preferred: I want to trigger everything from a command or a small configuration file, with no GUI pop-ups. Core capab...
