The goal is to ship a browser-based personal finance application that makes tracking income and expenses effortless yet precise. At its core, the system must centre on a single workflow: users record every transaction manually through one detailed form. That form should expose all the usual fields—date, amount, currency, payee, category, sub-category, payment method, notes, and an optional tag field—so nothing important ever stays hidden off-screen. Once stored, those records feed a clean dashboard that rolls totals, daily and monthly trends, and category breakdowns into quick-loading charts and tables. I want users to open the app and immediately understand where their money went today, this week, and this month, without digging through settings. A few practical notes: ...

I need a bespoke website that presents my business as a clean, modern portfolio. The look I have in mind is unmistakably modern and minimalistic—plenty of white space, tight typography, and subtle animations that keep the focus on the work itself rather than on decorative clutter. What the site must do • Act as a showcase: visitors should immediately see curated image galleries alongside short, well-structured articles that explain each project or service. • Load fast and scale well on mobile, tablet, and desktop. • Give me a simple way to update both the images and the accompanying text without touching code—either a lightweight CMS or a custom admin panel is fine as long as it’s intuitive. • Include essentials like a contact form, basic on-p...

My real-estate " " website needs a quick but thorough tidy-up. The current CSS causes layout problems, styling inconsistencies, and several responsive design glitches that become obvious on tablets and smaller phones. In parallel, the property search bar has stopped filtering by price, bedrooms, and location, so visitors often get zero or the wrong results. The website layout on the product banner should be like realtor.com. The backend admin is not working and cannot log in While reviewing the code, I also noticed that some listings show incorrect information, others render with a poor visual presentation, and a few disappear altogether. Those issues likely share a template or query root, so tackling them alongside the search repair should keep the work contained. Here is wh...

I want to enrich my current real-estate website with four tightly-integrated upgrades: • Interactive property map Google Maps must display every listing, allow cluster or pin views, and let visitors draw or click to filter by area. • “Save to Favorites” workflow A logged-in visitor needs a one-click way to add or remove any listing from a personal wishlist that is recalled on their next visit. If cross-device sync feels heavy for the first release, we can discuss a phased approach. • Built-in buyer/agent messaging A lightweight real-time chat pane should open straight from each listing so a buyer can talk to the assigned agent without leaving the page; think or Firebase-style push for instant delivery and read status. • Mobile-first speed...

The core game is Texas Hold’em and it must support true multiplayer tables where players can join, leave, and spectate without disrupting the hand in progress.

I’m building “Virtual Frame”, a browser-based tool (see ) that lets end-users upload a JPEG, preview it inside one of my pre-made frame templates, see an instant price that’s calculated automatically from the image and frame dimensions, and then download a ready-formatted PDF quote or order sheet.

I need a streamlined system that lets my field employees capture every mandatory document—identity proof, address proof, and the signed service agreement—while they are with a customer. They will upload these files through a secure web portal, so the interface has to be fast, mobile-responsive, and able to work even on patchy connections, queueing files until signal returns. On the backend, each document set must be stored and retrieved strictly by customer ID so that anyone in operations, compliance, or support can pull a full customer folder in seconds. I also want an at-a-glance timeline that shows where each customer sits in the overall journey, from first visit to final approval, along with an audit trail of every edit or status change. Core expectations • Respons...

I’m building a fully animated website in React and want every transition driven by GSAP for that extra-smooth, kinetic feel. The finished site must contain 14 pages, so the structure will go well beyond a simple Home, About, or Contact trio—I need fluid, eye-catching motion applied consistently across the entire experience. I don’t yet have a wireframe or visual concept, so part of the assignment is creative: you’ll help shape the overall UX/UI, propose a page hierarchy that makes sense for fourteen sections, and then implement it. Once we agree on the look, you’ll convert those designs into production-ready React components, layering in GSAP timelines for scroll-triggered reveals, interactive hovers, and page-to-page transitions.

I want to launch an e-commerce marketplace dedicated entirely to digital products—think software, templates, ebooks, music, and similar downloadables. Buyers should be able to browse items, add them to a cart, pay securely, then immediately receive their files.

I plan to launch a crypto-centric forum that feels as slick and forward-thinking as the topics we will be debating. Community discussions sit at the heart of the site, so every design and technical choice must encourage thoughtful, well-threaded conversations while keeping the pace fast for breaking news. What I need built is a browser-based platform that supports: • Classic threaded discussions with easy quoting, mentions and rich-text or markdown editing • A real-time live-chat channel (or channels) for quick-fire talk during market moves Account security is critical. New members will register through standard email sign-up, and two-factor authentication (app) must be available from day one.

I need a 1099 contractor who can commit 20-40 hours a week to split their time between a brand-new Rails API with a React front-end and an older legacy Rails monolith. Both codebases matter equally to the business, so you’ll be jumping back and forth—building fresh features in the greenfield project while keeping the legacy app functional and stable. We’ll kick things off with new feature development. The exact specs are still loose, so I’ll rely on you to help shape requirements, challenge assumptions, and translate rough product ideas into well-scoped user stories. Clean, well-tested, idiomatic Ruby and modern React are the baseline; RSpec, Jest/Testing Library, GitHub pull-requests, and CI/CD (we use GitHub Actions) are part of the day-to-day workflow. Delivera...
