Breez is a cloud-native, no-code automation solution that handles complex testing for web, mobile, and legacy systems (AS/400).

    This project involves optimizing and scaling a casino website built with React.js (frontend), (backend), and MongoDB (database), while also integrating PostgreSQL for improved data management. The first priority is to identify and fix existing bugs to ensure the platform runs reliably without crashes or inconsistencies. Alongside this, the frontend will be optimized for faster rendering, reduced load times, and a smoother user experience. The backend APIs and server-side logic will be improved to handle requests efficiently under heavy traffic. To support large-scale usage, the system will be redesigned with a scalable architecture capable of handling lakhs of users concurrently. This includes implementing load balancing, caching strategies, and efficient request handling. A hybrid databa...

    I’m extending a web app backed by Node.js and a SQL database and need a React expert to jump in right away. Your main jobs are to build several new components, fix a handful of lingering bugs, and refine the low-/no-code UX that business users rely on. What awaits you • System is built ready, so you’ll never be coding in the dark. • The new pieces revolve around data-display tables, dashboards, and filterable views, with a few interactive forms sprinkled in. • All components must drop seamlessly into our existing pages, pulling data from the REST endpoints already exposed in Node. Acceptance criteria 1. Every component matches the supplied designs pixel-for-pixel and remains fully responsive. 2. Filters return accurate results in under 300 ms agains...

    I have a couple of active web projects that need an experienced developer comfortable in both ASP.NET and PHP. Some modules are already live, others still sit in prototype form, so you may be writing fresh components one day and refactoring legacy code the next. Your day-to-day work will revolve around: • Implementing new features that slot cleanly into the existing architecture • Squashing bugs and tightening security in the older code paths • Writing clear, well-commented code and concise commit messages so future maintenance stays painless You’ll work in Git, commit to feature branches, and open pull requests for review. When you push an update, I’ll test it on a staging server and give feedback within 24 hours—rapid iterations matter to me. ...

    I’m ready to build the first-generation mobile app for our golf company and want it released simultaneously on iOS and Android. In this initial version the priority is straightforward functionality, not flashy extras. Here’s what Gen 1 must do: • Pull live information from the Google Sheets we already use for player notes and make it easy for a coach or athlete to browse and update those records on their phone. • Store and display fitness data so users can track workouts, mobility routines, and training metrics alongside their golf notes. • Let me upload short swing videos or screen-recorded tips and have them play smoothly inside the app. Access will be secured with a simple email-and-password sign-in; no social logins for now. I’ll supply the c...

    I need hands-on guidance while I set up a fresh Facebook (Meta) advertising stack focused on conversion ads for lead generation. At the moment I have no Pixel in place and my GoHighLevel account is not yet connected to Meta, so nothing is tracking correctly. Your role is to walk me through each step live (Zoom or similar), making sure I understand what we are doing and why, then verify that everything fires as expected: • Install and verify the Facebook Pixel on my website and funnels • Connect GoHighLevel so leads flow back to Meta and events are passed accurately (standard events + Conversion API if practical) • Structure the ad account, campaigns, ad sets, and ads for a clean conversion-focused setup, ready to scale • Show me how to test events inside Event...

    I need a production-ready dashboard built on Node.js that streams website-traffic data in real time, lets me administer users, and pushes notifications to the right people instantly. For the visual layer, think smooth charts that update live via WebSockets or without forcing a page refresh. The traffic feed is already available from our analytics endpoint, so your job is to consume that JSON stream and render it with a library you feel comfortable with—, D3, ECharts, or similar—as long as the result stays responsive on desktop and mobile. User management must be fully integrated: role-based access control, individual user profiles, and searchable activity logs so I can trace who did what and when. A simple admin UI for creating roles, assigning permissions, and viewing audit...

    I want to take my existing WordPress site and give it a truly premium look that matches top-tier global engineering firms. The objective is clear: elevate the visual design while keeping every current URL intact so our hard-earned SEO remains untouched. Here’s how I’d like the process to flow. First, you’ll create 3 completely unique homepage concepts in Figma—no templates, no ThemeForest bases, nothing recycled. Once we choose a direction, you will build a clean, lightweight custom theme on WordPress that mirrors the selected concept down to the smallest interaction. The site needs to be bilingual (English + Arabic) with full RTL support, and roughly 15 pages in total: home, about, ten individual service pages, projects portfolio, news, careers, and contact. Al...

    I’ve put a quick patch in place for my site—setting every element to border-box, hiding horizontal overflow, and forcing columns to stack under 768 px—but a few stubborn layout issues remain. Some components still break their boxes, the page can occasionally scroll sideways on mobile, and the float overrides don’t feel future-proof. I’d like you to audit the stylesheet, identify what is really causing the overflow and sizing glitches, and deliver a clean, well-commented CSS (or SCSS) update that: • keeps a consistent border-box model everywhere, • eliminates any unexpected horizontal scroll on all viewports, and • lets column-based sections collapse gracefully on small screens without relying on important-heavy quick fixes. Please te...
