Hosted on Replit (Autoscale deployment). The Problem: The app works perfectly in development mode, but after deploying to production on Replit, the browser shows a blank/white screen. No visible errors in the browser console (or provide any you do see). Build Process: Vite builds the frontend to dist/public, esbuild bundles the server to dist/index.js. Express serves the static files in production. The build command is npm run build && npm run db:push, and the production run command is node dist/index.js. What I Need: Diagnose why the production build renders a blank screen Fix the issue ...

    I’m putting together a corporate head-count tracker and I want to move quickly from concept to a secure, production-ready application. The backend will run on Spring Boot; the frontend needs to be available both as classic HTML/CSS/JavaScript pages and as a richer React interface, so we can serve different devices and gradually migrate stakeholders toward React. Security is essential. I need full user authentication with clear role separation—Admin and User—implemented with Spring Security (JWT or another proven token strategy). Beyond wiring the login flow, I also want advice on best-practice password storage, CSRF protection, and anything else you see fit to lock things down. Where I need your help: • Designing the Spring Boot architecture, setting up entities, r...

    The frontend of the project is done. However, I am unable to integrate Supabase as it crashes when I do. I am not familiar with Supabase. This project has user management, with separate portals for Admin, Interpreter, Client, and Staff. It has various workflows (example: Registration-> User Management; Booking Request-> Job Creation -> Assignment Tracking -> Completion Report -> Invoicing -> Payment) and integrations between users (Admin <-> Interpreter, Admin <-> Staff). It is also important that email integration is seamless.

    I need a blazing-fast, fully responsive online store built with and Tailwind CSS. Use whichever backend stack—Node.js or Python—helps you move quickest, pairing it with either PostgreSQL or MongoDB for data storage. The project must deploy cleanly on Vercel (Netlify is fine too) with seamless CI/CD. Core requirements • Server-side rendering plus rich Schema Markup so products surface on Google immediately. • Image delivery through Cloudinary with automatic compression and responsive breakpoints. • Secure checkout via Razorpay or Stripe, covering the full order lifecycle—cart, payment, confirmation, refunds. • Google Analytics 4 events for product views, add-to-cart, checkout start, and purchase. • An admin panel to add and edit product...

    I need a full-stack developer to build a website in Node.js that cleanly presents three core areas—business listings, a blog section, and a product showcase—supported by a secure admin panel. The admin area must let me create, update, and archive content for each of those modules using a straightforward email-and-password login flow. Visual direction is modern and minimalist: lots of white space, clear typography, subtle accents, and a layout that feels snappy on both desktop and mobile. I’m happy for you to pick the most suitable Node.js framework (Express, Nest, Next, etc.) and database, as long as the code is modular and easy for another developer to pick up later on. Key deliverables: • Responsive public site with the three content sections wired to dynam...

    My Ruby (Rails) API usually answers in milliseconds, yet at unpredictable moments the same endpoints take seconds to return. Standard logs show no spikes in traffic, and CPU / memory look normal, so I suspect a hidden bottleneck—perhaps DB connection exhaustion, an elusive N+1 query, or a background job starving Puma threads. You will dive into the codebase, profile the request/response cycle, pinpoint the root cause, and supply a clean fix that restores consistent response times. Feel free to use rack-mini-profiler, New Relic, Scout, or your preferred Ruby profilers; the server runs Ruby 3.1 and Rails 7 on PostgreSQL. Deliverables • Diagnostic report summarising findings and root cause • Patch or pull request with the optimised code/configuration • Before-an...

    The idea Implement an API whose goal is to produce routes that are: - 100% drivable (Directed & Drivable) - Truly diverse (not just different geometry) - Geometrically stable, with no stitching issues or incorrect direction reversals - Close in performance and behavior to Google Maps / Waze (very important) What I’m specifically looking for I’m looking for a developer who understands road networks as real graphs, not just as lines drawn on a map. The right person must be comfortable with: - Directed graphs - One-way roads & carriageways - Edge-based diversity - Geometry correctness Current required tasks (very important) Implement a single API endpoint that returns multiple routes: 1 - The natural route (Google/Waze-like): - Fastest / shortest path - Acts a...

    Please Read Carefully Before Applying It does not matter whether you consider yourself a “vibe coder” or a traditional software engineer we accept both here. What matters is whether you can make this system work reliably at scale. We operate a production scraper that processes 500+ leaderboard sites per hour. All sites we scrape are leaderboards, but no two sites are the same. This is not a basic scraper. What Makes This Scraper Different The leaderboards we scrape vary heavily in structure and behavior: Dynamic buttons, tabs, and switchers JavaScript-rendered content Hybrid navigation (UI interaction + background API calls) Tables, card layouts, podium layouts, or combinations of all three Masked usernames and inconsistent rank formats Different ordering of wager / prize data ...

    I’m racing toward launch and need a backend ace who can dive straight into my Hostinger setup, show real code today, and keep pace with aggressive milestones. The environment is Python backed by PostgreSQL, with Hostinger’s AI tools playing a central role. First priority is wiring reliable cron jobs, refactoring what’s already in GitHub, and embedding the AI endpoints cleanly into the existing API layer. While you’re there, run a performance sweep—profile, optimise, and make sure every Postgres query is bulletproof. Deliverables for the opening sprint: • Pull request that proves the cron jobs execute on Hostinger and log cleanly. • AI tool integration wrapped in clear, testable Python modules. • Concise review memo highlighting bottl...
