    我需要一套小巧的软件,能够通过 提供的 API 实时拉取用户资料,并在界面或表格中直观地展示出“姓名、注册手机号、余额”三列数据。 
 目前我手里没有任何 API 认证信息,因此第一步可能需要你帮我梳理官方文档、抓包或其他合规方式,确定接口地址与 Token 获取流程,再把认证配置写进程序。数据调用应当按需触发——当我点一次“刷新”或执行命令时,系统即时向接口发起请求,而不是定时轮询或依赖事先上传的 CSV。 我对具体开发语言没有强制要求,Python、Node.js、Go 甚至轻量的 CLI 工具都可以,只要: 1. 成功获取上述三项字段,并支持导出/复制; 2. 源码结构清晰,接口与 UI 分离; 3. 提供简单的本地部署说明(依赖、启动方式、如何填入 API Key)。 交付时请附: • 完整源码与可执行文件 • README 或简短视频演示,证明能在我侧复现 如 API 最终不可用,也请在报告中说明理由并给出可行的替代思路,但首选仍为纯 API 调用而非浏览器自动化或 Web 抓取。

The focus is on high-quality HTML5 and WebGL titles that load instantly in the browser across desktop and mobile, so every technical choice has to revolve around performance, asset compression, and responsive design. Core experience • Games: Primarily HTML5, with WebGL support for more demanding titles. • Feel: Clean, lightweight interface that still looks like a major gaming brand. Page transitions should be fluid and the site must pass Core Web Vitals on mobile. • Hosting & publishing: I want a workflow where I can drop in new game builds, set metadata, and have the title live—think a small CMS or ...

Accuracy and speed are more important to me than flashy UI, but the interface must still be clear enough for HR staff to view logs and pull reports with zero training. Core functionality I expect: • Real-time attendance logging as soon as a face is detected • Instant notification alerts (e-mail, push, or SMS—whatever integrates cleanly) when someone signs in, signs out, or when an unknown face appears • Report generation that can be filtered by date range, department, or individual employee, exportable to CSV and PDF • A webhook endpoint so our internal systems can consume every check-in or alert programmatically Feel free...

Immediately assign the required product licenses to those users. 3.

Core scope • Hours-tracking module: volunteers enter time, edit past entries, and view personal and aggregate stats. • Instagram tie-in: pulling our hashtagged posts into a simple feed on the dashboard and giving admins one-click sharing of top volunteer highlights back to Instagram. OAuth-based sign-in is fine; no need for Facebook or Twitter right now. • Admin view: exportable CSV of logged hours plus a concise summary panel showing totals by volunte...

The flow is straightforward: call the API, parse the JSON payload, map the fields to table columns, then render each table so it paginates gracefully and, when necessary, repeats headers across pages. Key points • Source data arrives solely from an API in JSON format—no manual entry or secondary feeds. • The PDF contains tables only; no images or free-form text blocks beyond table headers or footers you may add for clarity. • Any solid, maintained library is fine—pdfkit, Puppeteer, jsPDF, or a comparable Node.js toolset—as long as it supports custom styling (borders, alte...

    Steam Sweepstakes Web App

    I need a mobile-responsive web app that lets visitors sign in through the Steam API, automatically pulling their SteamID so they can enter free sweepstakes with a single click. The core build should feel snappy on phones first, then scale gracefully to desktop. Key flow • User arrives, taps “Sign in with Steam,” and is authenticated via OpenID. • Once logged in, the site tracks each entry they make, stores it under their account, and presents a simple profile page that shows only their sweepstakes history. Sweepstakes engine An automated job must close each giveaway at the scheduled time, randomly select a winner from valid entries, and fire off both an on-site and email (or Steam message if feasible) notification. I also want an admin view where I can start...

    I’m building an end-to-end marketplace that connects car-salvage yards with buyers looking for specific parts. The project covers two products working in tandem: 1. A cross-platform mobile app targeting both iOS and Android. Within the app users must be able to: • search the entire catalog of salvaged parts by keyword, make, model, year, and VIN • post new parts for sale from the yard side, including photos, descriptions, condition, price, and inventory count • chat in real time so buyers and yards can negotiate or confirm fitment before checkout 2. A responsive web dashboard for yard owners and internal staff. The dashboard needs robust: • inventory management (batch uploads, stock alerts, status changes) • user management (role-based access, suspension/ap...

    I need a small-scale community-focused website that offers two sign-in options: Google OAuth (Gmail) and a classic email-and-password flow. The primary goal is community engagement, so once users are inside they must be able to create a profile, edit basic details, and exchange direct messages with each other. No e-commerce, no complex forums—just a clean, responsive space for members to connect. A lightweight tech stack is fine as long as it is secure and quick to deploy; React or Vue on the front end and Node, Django, or Laravel on the back end would all work if OAuth and secure password storage are implemented correctly. Mobile-friendly layout is required, and I’d like the initial build hosted on a standard cloud service (AWS, Heroku, Vercel, or similar) so I can test it li...

    I have already created the subdomain of my main domain where will live and I can give you full SSH/root access to the Linux server that powers it (Ubuntu 24.04 with HestiaCP panel running on port 8083 of main domain). Subdomain has ssl via Let's encrypt. All I need is a clean, production-ready installation of the latest stable release, configured so it loads flawlessly from the subdomain (HTTPS, reverse proxy, environment variables, database, etc.). I have a VPS hosted by Hostinger. You are free to use the official Docker set-up or a manual Node.js build—whichever you feel is most reliable—but please secure it properly, connect it to a Postgres database (which has to be setup as well), and leave me with concise notes so I can maintain or upgrade it later.
