    I own a bike-rental company and need a web application that lets customers book their bikes completely online. The core of the project is a streamlined booking flow where riders can browse my fleet, pick the exact model they want, and immediately see whether it’s available for their chosen dates. An interactive calendar should make date selection quick and intuitive, and once a slot is locked in, inventory must update in real time so double-bookings never happen. On the back end I want to add, edit, or retire bike models, adjust pricing, and block out maintenance periods from a simple dashboard. Every confirmed reservation should appear in an admin view where I can manually override or cancel if needed. The interface has to be mobile-friendly (most customers will book from their ph...

    I already have a fully developed Node.js application and now need it live on my company website. The site's sole purpose is clear, reliable information display—no e-commerce or complex customer-interaction modules at this stage. Here’s what I’m looking for: • Prepare the hosting environment, deploy the Node.js code, and wire it to the production domain. • Configure SSL so everything runs over HTTPS. • Set up environment variables, build steps, and a process manager such as PM2 (or a comparable tool) to keep the service running automatically after restarts. • Connect any database or external services the project already references. • Optimize basic performance and security settings (rate limits, headers, logging). • Deliver a s...

    I need the TwentyHQ/Twenty repository deployed on , but the current Railway template is lagging behind the main branch and misses the new AI functionality. My first priority is to build and push a fresh Docker image that faithfully tracks the latest commit of the project. repo Once the image is up-to-date, I’ll need a Railway service created (or updated) with several custom settings: • Environment variables that mirror those in the upstream repo plus any extras required by the new AI modules. • Custom build commands so the container installs dependencies, runs database migrations, and compiles assets exactly as Twenty expects. • Unique network rules—specifically port exposure and any reverse-proxy headers—to keep the app reachable and secure in Rail...

    I need a Telegram-based AI assistant that can act as a true subject-matter expert. The core idea is simple: we will feed it a large, well-structured document set from whichever industry offers the richest material, then let the bot do the heavy lifting. While the sector itself can be decided once I see which corpus is most complete, the bot must speak fluently about Artificial Intelligence concepts in particular, as that will be a recurring theme in user queries. Once deployed the assistant should: • read and index every document I supply (PDFs, Word files, web links, internal wikis) • answer ad-hoc questions instantly, citing sources • provide actionable recommendations where appropriate • deliver concise summaries of lengthy texts on request I expect a smo...

    I’m Priya Batra from XRS Technologies. We specialise in IT services while also running student training and internship programmes, and now we need a modern web presence that reflects both sides of the business. The stack is fixed—MongoDB, Express, React and Node—so I’m looking for someone who already works comfortably across that entire spectrum. In our kickoff call I’ll share the full sitemap, content, feature list and required admin controls. From there, your role is to translate those assets into a clean, responsive and highly scalable site with a polished, professional UI/UX. Code quality matters as much as design: well-structured React components, efficient API endpoints, clear MongoDB modelling and straightforward deployment (AWS, Vercel or similar) wil...

    Egy olyan irodai alkalmazást szeretnék, amely egyszerre kezeli az ügyeket, az ügyfeleket és a határidőket, miközben a kapcsolódó iratokat is rendszerezi. Fontos, hogy az adatok könnyen exportálhatók legyenek – például Excel- vagy CSV-formátumba – így a rendszernek biztosítania kell egy letisztult exportfunkciót. Fő feladatok: • Ügy- és ügyfél-nyilvántartás kialakítása: kereshető adatbázis, alap- és egyedi mezőkkel. • Iratkezelés: fájl-feltöltés, verziókezelés, jogosultságok. • Határidő-nyilvántartás: rugalmas e...

    I’m launching a new project that needs both a mobile application and a matching responsive website built from the ground up. At the moment the exact platform mix is still open—iOS, Android, or a cross-platform solution are all possibilities—so I’m looking for technical guidance on the best route. Likewise, the site could evolve into an e-commerce storefront, a content-driven blog, or a sleek portfolio; the final decision will be shaped by the strategy we outline together. What matters most is a clean, scalable codebase that pairs modern front-end frameworks (React, , Flutter, React Native, etc.) with a robust backend you’re comfortable maintaining—Node, Django, Laravel, or another stack that fits. I’d like everything version-controlled in Git, dep...

    I need a seasoned backend developer to take full ownership of the server-side engine for a new ecommerce platform and stay on for ongoing maintenance as we scale. The scope begins with architecting a clean, well-documented API layer that powers the entire buyer journey—from browsing the catalogue and filling a cart, through checkout, payment, and post-purchase flows such as returns. In parallel, you’ll build out the seller pathway: onboarding, KYC verification, inventory sync, and order management. Key requirements • Robust cart, checkout, and return logic that can handle discounts, promotions, and edge-case calculations without breaking state. • Seamless Razorpay integration (cards, wallets, net-banking—all via Razorpay’s SDK and REST endpoints) with...
