    I’m launching a full-scale online arcade inspired by the polish and speed of CrazyGames, and I need the entire web platform engineered from the ground up. 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 ...

    I need a web-based face recognition system that records employee attendance the moment someone shows up, without any manual check-in. 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...

    I need a small, reliable script or lightweight service that talks directly to the Adobe Admin Console APIs so I can stop onboarding users by hand. The automation must do three things every time it runs: 1. Create new user accounts (or recognise existing ones without duplication) from a simple CSV, JSON, or similar input. 2. Immediately assign the required product licenses to those users. 3. Export the Linkedin premium 3 months free benifit link Only “assign licenses to users” is in scope for license allocation; deeper usage-tracking reports are not required right now. Robust error handling, clear logging, and repeat-run safety (idempotency) are essential. A concise README that covers prerequisites, API credentials, and step-by-step execution completes the job.

    I need a lightweight, AI-flavoured MVP that lets volunteers log and track the hours they devote to our projects, all from a single web dashboard. The build should feel modern and “smart” in its UX—think quick, predictive form fills and clean analytics rather than heavy-handed machine-learning features. 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...

    I need a clean, well-documented Node.js solution that fetches JSON data from a specified API endpoint and turns it into a professionally formatted PDF made up exclusively of tables. 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...

Scope of work • Plan the overall architecture, database schema and a clean, mobile-friendly interface. • Create secure user roles for brands, influencers and administrators. • Build modules for influencer discovery, automated campaign workflow and real-time analytics. • Integrate with Instagram, TikTok, YouTube (and similar) APIs so follower counts, engagement rates and post metrics sync automatically. • Include an admin dashboard where I can approve or susp...

The core idea is simple: users open the app and immediately see fresh, well-structured content that I publish through an admin dashboard. Clean navigation, quick load times, and an intuitive layout are critical. Here is what I have in mind: • Cross-platform build using Flutter or React Native so we keep a single codebase. • A lightweight backend (Firebase, Supabase, or a Node + PostgreSQL stack) that lets me log in, create articles, tag them, and push updates instantly. • Push notifications the moment new content goes live. • Basic user analytics so I can track reads, session length, and popular topics...

Real-time updates are central to the experience, so you should be comfortable wiring WebSockets or a layer that keeps every client instantly in sync without page refreshes. Here’s the flow I have in mind: • Design a clean, reusable component architecture in React (hooks, context, or Redux—whichever you know will scale). • Stand up a lightweight Node.js/Express API that pushes and receives real-time events efficiently. • Connect the two, secure the traffic, and deploy to a cloud host so I can test live.

    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.

    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.
