I have a web application and now need Twilio woven into it so that all communication runs through a single, reliable provider. The core requirement is straightforward: connect my current web stack to Twilio’s APIs, handle authentication, and expose clean endpoints or UI hooks that the front-end team can consume. The exact feature set is still flexible, but the build must be future-proof. We will share the code with the right developer willing to work
I need a full-stack, SaaS-ready solution that lets residents, committee/admin members and security guards handle all daily society tasks from their phones while I oversee everything from a web dashboard. Core workflow • Users sign in with mobile-number OTP and see only the screens tied to their role (Resident, Admin, Guard). • The mobile build must run smoothly on both iOS and Android, using a single codebase if that speeds things up. • A clean top navigation bar should guide every screen transition. Key modules Visitor Management – residents can pre-approve guests; guards simply scan/enter details at arrival and departure; both sides get immediate status updates. Complaints – residents file an issue, watch it move from Open → In Progress → ...
I have a web application-company website in active development and now need a developer who feels at home in React while still understanding the wider full-stack picture. The immediate focus is on polishing and extending the front-end: building new components, tightening up state management, and wiring everything cleanly to Firebase (Firestore, Auth, Functions, Hosting). I work iteratively: small, well-defined tasks that roll into weekly pushes to production, so clear communication and clean Git commits matter to me. When you reply, show me concrete past work that proves you have already shipped React projects backed by Firebase. GitHub links or live demos that highlight responsive UI, sensible folder structure, and secure data handling will help me move quickly to hire. If you thriv...
My Node.js website is running smoothly on my local machine; now it needs a permanent home on my GoDaddy VPS so the public can reach it through the domain already sitting in my GoDaddy account. Here is what I need from you: • Move the current project from local to the VPS (SSH, Git or any secure method you prefer). • Install the required Node.js version and production dependencies. • Set up a process manager such as PM2 to keep the app alive and auto-restart on reboot. • Configure a reverse-proxy (Nginx or Apache) so the site serves over port 80/443. • Update or create the necessary A/AAAA and CNAME records; I marked “Yes” for DNS help because I want the domain to resolve cleanly worldwide. • Apply an SSL certificate (Let’s Encry...

I need a small, self-running script or service that will automatically purchase new leads the moment a listing that matches my settings appears online. The logic is straightforward: watch for the keyword “Clothing”, restrict the search to the United States, United Kingdom and Australia, confirm the required order quantity that I will set in a config file, and then trigger the purchase workflow without manual input. I am flexible on the underlying marketplace API you prefer to work with—what matters is that the solution can reliably poll the chosen platform, filter by the country marketplace flag, evaluate the quantity field and complete the checkout through secure, stored credentials. A lightweight dashboard or log file that shows each transaction in real time will mak...

I’m ready to give my current website a meaningful refresh and need a developer who can step in, review what’s live, and move it forward without disrupting what already works. The core goal is to update the site rather than rebuild it from scratch, so you’ll be working with the existing codebase and content structure. Here’s how I see the collaboration: • First, you’ll audit the site, identify outdated sections or code, and outline quick-win improvements alongside any deeper changes worth considering. • Once we agree on a priority list, you’ll implement the updates, making sure the look, feel, and functionality stay consistent across modern browsers and devices. • Clear, well-commented commits are essential so I can track progress and...

I am building a series of n8n workflows that must bring together databases, multiple external APIs, spreadsheets, and cutting-edge LLMs in one seamless automation layer. The goal is to handle data integration, end-to-end process automation, and sophisticated API connections without manual touch points. You’ll be extending n8n beyond its out-of-the-box nodes, so solid JavaScript/TypeScript skills and full-stack experience are essential. I’ll rely on you to create custom nodes where needed, orchestrate error handling and retries, document each step clearly, and containerise the final solution (Docker preferred) for straightforward deployment. Deliverables • Fully functional n8n workflows covering database, API, spreadsheet, and LLM integrations • Any custom nodes ...
I need a web-based dashboard that lets me monitor core business analytics at a glance. The focus is on clear, responsive charts and graphs that track two critical metrics: sales performance and website traffic. The data will come from sources I can expose through REST APIs or flat files, so the build should accommodate both. I’m open to the charting library you prefer—whether that’s D3.js, , Highcharts, or another modern JavaScript option—so long as the visuals load quickly and can be filtered by date range, product line, and traffic channel without page refreshes. Please structure the project so future datasets can be plugged in with minimal code changes. A lightweight admin panel or straightforward config file approach is fine; I just don’t want to wad...

I’m building a central API that receives every new order from my Wix storefront, checks real-time stock across three nearby locations, compares both availability and price, then decides which store should fulfill the sale. Once the choice is made, the same service must decrement inventory at that location and raise an instant alert whenever stock dips below a threshold or sales spike unusually. Because I have no existing back-end, the whole pipeline—orders, inventory, pricing, and alerts—needs to be created from the ground up. Orders integration is my top priority, so the initial milestone should prove that an order placed on Wix can travel through the API, retrieve inventory data, and respond with a recommended store. I’m open to your suggested stack: Node.js wit...
Rural Chatbot – AI-Based Government Scheme Discovery Platform I developed a smart chatbot system designed to help rural users easily discover and understand government schemes they are eligible for. The platform solves a major real-world problem: most people in rural areas struggle to find relevant government schemes due to complex websites, lack of awareness, and language barriers. Key Features: • Personalized Scheme Recommendation – Users get schemes based on their profile (age, income, state, category, occupation) • Intelligent Chatbot – Users can ask questions in natural language and receive accurate answers • Eligibility Checker – Instantly shows schemes a user qualifies for • Multilingual Support – Supports English and Hindi for be...

Here’s the framework: • Stack: Amazon Selling Partner or Product Advertising API, Python (or Node), secure REST endpoints, and prompt engineering with Claude to handle data cleaning and enrichment. • Scope: architect and code the complete collection pipeline, schedule it (cron/Lambda), store results in a lightweight persistent layer, document the setup, and hand off ready-to-run scripts. • Workflow: you’ll collaborate with me through Git,...
I want a web platform that lets Murder Mystery 2 players stake their Roblox items in real-time games—coin flip, jackpot and an upgrader—modelled as closely as possible on the look, feel and flow of bloxybet.com. Coin Flip • Any number of coin-flip rooms can run in parallel. Players should be able to open a room, set the wager, share the link and wait for an opponent, or instantly join an open room. The interface needs the same fast, casino-style experience Bloxybet offers, with live status updates through WebSockets or a similar solution. Jackpot & Upgrader Both games must mirror Bloxybet’s mechanics: tier-based jackpot pools that roll on a timer, and an upgrader where players select an item, choose a percentage chance and see an animation revealing suc...

Environment & tech • Our CRM is custom built, so you will be working with a clean REST interface on our side. • Authentication into our stack is OAuth 2.0; the same flow should be used when talking to MYOB’s cloud endpoints. • MYOB AccountRight API documentation and sandbox credentials are ready for you. Deliverables • A documented REST endpoint in our CRM that accepts invoice data and pushes it to MYOB AccountRight. • All supporti...
I am embarking on a green-field build of an end-to-end business platform and I need an experienced full-stack partner who has taken similar products from concept right through to launch. Scope The core of the project is a web application that must run smoothly on desktop, mobile, and tablet browsers. Native iOS and Android apps will follow, powered by the same back-end.

I manage a growing mix of e-commerce, corporate and brochure sites and I’m tired of jumping between tools to check whether each domain is online and how its SEO is trending. I need a single, browser-based dashboard where I can enter a list of domains and instantly see: • Live health data: a clear online/offline indicator, current uptime percentage and SSL certificate status. If you can tack on any other low-effort metrics such as basic response time, all the better. • Core SEO signals: up-to-date keyword rankings, page-load speed and an overall “priority” score that tells me which site deserves attention first. I’m open to a simple formula for that score at launch and will iterate with you later. Feel free to lean on readily available APIs—Pingdo...

I need a full-cycle web developer who can deliver a hotel-only booking site that feels effortless on phones first.
