    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...

    I need a small 2-D arcade game built with plain HTML, CSS and JavaScript that I can instantly run and demo on Replit. The core loop is simple: the player steers a character with on-screen touch controls, dodges obstacles and can tap to shoot them down while racking up points. What I care about most is clarity and portability. A clean, lightweight UI, a live score counter, and a game-over overlay with a restart button should all resize gracefully on phones and desktops alike. Please keep the visuals straightforward—feel free to propose either a flat, minimalist look or a quick retro pixel style as long as it stays fast to load. Code quality is important: comment the logic thoroughly, avoid heavy frameworks, and structure everything so I can fork the Replit project and underst...

    Shopify Cart Bug Fix -- 2

    I’m running the Prestige theme on Shopify and the cart has started misbehaving on mobile—both iOS and Android. Whenever a shopper adds a product, the cart grabs the previous item instead, so the cart is always one step behind. Swiping through product images or switching variations triggers a “SyntaxError: The string did not match the expected pattern,” blocking the add-to-cart action entirely. Removing items or updating quantities fails as well. Key pain points you’ll tackle: • Adding products, removing items, and changing variations must work reliably on mobile. • The cart should display the correct, current product every time. • No more SyntaxError on variant change. I haven’t modified the theme or added new apps recently, so the...

    I want to launch a full-featured web platform where users can swap value across different digital ecosystems. The exact mix of assets is still open for discussion—I might start with mainstream cryptocurrencies, expand to popular in-game coins, or even fold in loyalty points once the core is stable—so the architecture needs to stay modular and asset-agnostic. Here’s what I need from you: • A scalable backend that can plug into multiple asset ledgers (blockchain nodes, game publisher APIs, loyalty program endpoints) without rewriting core logic. • Secure user accounts with 2FA, encrypted wallets, and a clean audit trail of every transaction. • A matching engine that handles simple market/limit orders, shows real-time order book depth, and calculates fee...

    My WordPress site feels snappy on the front-end, yet the server is taking too long to assemble each page. The priority is clear: cut backend processing time so visitors receive content far faster. The work centers on three intertwined areas: • Plugin performance – audit active plugins, remove or replace heavy ones, and refactor any custom code that slows execution. • Database queries – profile slow queries, add or adjust indexes, and fine-tune wp_options or autoloaded data to reduce query count and execution time. • Theme code – streamline template files, eliminate redundant functions, and ensure hooks run only when required. I already handle basic caching and asset minification; the bottleneck lies deeper. Please benchmark before and after (...

    I want visitors to enter their date, exact time, and place of birth on my WordPress site and instantly receive a full suite of Vedic astrology results. The module needs to compute and display every divisional chart from D1, D9, D10 through D60, show lucky numbers and lucky colours, and lay out key insights such as planetary positions, house (Bhava) placements, and Nakshatra positions. I do not yet have production-ready code, so please bring or build the complete calculation engine. Whether you adapt an open-source ephemeris (e.g., Swiss Ephemeris) or write fresh PHP/JavaScript routines is up to you, as long as the output is accurate and the front-end embeds cleanly through a shortcode or block. Acceptance will be based on: • Correct rendering of all D1–D60 charts with proper...

    I’m developing a platform that lets companies who rely on cassava flour speak directly with cassava-growing farmers. I need both a responsive web app and a companion mobile app released together so users can choose whichever device suits them best while still sharing one real-time database. The single must-have feature is seamless, reliable communication. Farmers and buyers should be able to: • exchange instant messages in real time (typing indicators, read receipts, image/file sharing) • jump into one-to-one or group video calls without leaving the app, on desktop or mobile Please architect, build, test and deploy the full stack needed for those tools—including user authentication and a simple profile header for each party—so that a farmer can sign in, rece...

    My Shopify store is live but needs sharper, more reliable functionality. I’d like you to audit the current setup, identify weak points in the customer journey, and then implement targeted improvements. A key part of the job is integrating fresh third-party apps or services—think new payment gateways, advanced search or filter tools, inventory or shipping solutions, marketing automations, or anything else that can elevate performance and sales. Here’s how I picture the collaboration: • Functional upgrades applied without breaking the existing theme or design • New apps installed, configured, and tested end-to-end (checkout, inventory sync, analytics tracking, etc.) • Any legacy code cleaned up so the site remains fast and conflict-free • Clear n...

    I need a compact, professional-looking website that lets visitors follow the weekly performance of my two live trading accounts. The heart of the build is a clear, corporate-style dashboard that combines interactive charts with tidy data tables, so both visual and numerical readers get the story at a glance. Key performance indicators I want visible for each account are: • Profit/Loss • Current Account Balance • Winning Trades Percentage • Drawdown • Number of wins vs. losses • Percentage gain since creation • Side-by-side comparison with a benchmark Data will be refreshed once a week; a simple admin upload (CSV, Google Sheet sync, or broker API endpoint—whichever is quickest to maintain) will work fine. Alongside the dashboard, I n...

    I need a fresh, visually striking redesign for so it clearly functions as a portfolio hub. The current site no longer reflects the quality of my work, and I’m ready for a complete visual overhaul rather than tweaking the existing look and feel. My top priority is letting visitors browse the portfolio quickly and intuitively—clean navigation, bold imagery and smooth performance are must-haves. While I’m open to the platform you recommend (WordPress, Webflow, custom HTML/CSS with a lightweight CMS—whatever fits best), the finished site should: • Highlight each project in a consistent, gallery-style layout with room for future additions • Load fast on desktop and mobile, following modern responsive standards • Be easy for me to update without touc...
