    I’m running a chat interface powered by Wasphere (guide: ). The front-end already lets users attach fi... Everything appears to post, yet nothing ever reaches the recipient. My hunch is that I’ve wired the wrong API endpoint, but the real weakness seems to sit in the current file-handling logic on the server. I need you to step through the PHP, confirm how the files and audio are packaged, verify the Wasphere endpoint, and patch whatever is blocking delivery. Scope of the fix • Review existing JS upload/record code and corresponding PHP upload handler. Acceptance criteria – A user can attach an image, PDF, or other document and the recipient sees it instantly. – A recorded audio clip plays for the recipient with no corruption.

On the interface side I need clean, customisable dashboards: users should be able to pin preferred currency pairs, tweak look-back windows, and view recommended structures at a glance. A charting library such as Plotly, Highcharts or TradingView JS is fine—pick the one you’re most comfortable with. Because the output influences trading decisions, accuracy and latency matter.

    I need help building a modern, responsive user interface for an existing web application. The back-end and infrastructure are already running on AWS Linux servers with managed databases, so your focus will be purely on the front-end layer—turning wireframes and REST/GraphQL endpoints into a smooth, production-ready experience. There is no firm framework locked in yet; React, Vue.js, or Angular could all work. I’m happy to decide together once you have reviewed the current codebase and performance goals. Whichever library we pick, clean component architecture, state management best practices, and thorough cross-browser testing are essential.

    ...open-rate tracking. Preview in multiple clients would be nice to have, but again, the non-negotiable is accurate manipulation of the displayed send date. • A clean interface matters: ideally an Outlook add-in ribbon button or a small standalone companion app where I can draft, choose a past timestamp, and hit “Emulate.” Deliverables I’ll accept 1. A fully working prototype (VSTO add-in, Office JS add-in, or another approach you recommend) that back-dates emails reliably inside Outlook 2016+ and Microsoft 365. 2. Source code with concise inline comments. 3. A short setup guide and a quick demo showing the timestamp override in action. If a specific API limit, security setting, or Exchange policy could block this behaviour, flag it early so we can...

    I handle a continuous stream of small-to-mid-size sites that have to be built and cared for from the ground up. Every project is coded directly in HTML5, CSS3 and modern JavaScript—no CMS layers—so I need a developer who is completely comfortable in a ...error-free, validate through W3C, and retain full responsiveness from 320 px mobile up to large desktop breakpoints. I can usually guarantee 10–15 hours of work each week, scaling up when new sites roll in. Communication happens in Slack for quick questions and a Trello board for task tracking; I’m in UTC+2 but async updates within 24 h are fine. If you’re confident working solo on raw HTML/CSS/JS builds, enjoy iterative maintenance, and are looking for a stable, long-term remote collaboration, I&rsqu...

    ...launch. Here’s the experience I’m after: smooth transitions between sections, crisp animations that don’t slow the page down, and a structure that search engines love.

    My web app currently runs in just html + some js environment and I’d like its JavaScript bundle slimmed down and shielded from easy copying. The task is straightforward: • Take the existing JS files from my repo, run them through a minification and obfuscation pipeline (tool choice is open—Terser, javascript-obfuscator, or any solid alternative). • Preserve 100 % of current functionality and visual behaviour—no feature regressions. • Package the process into a repeatable build step (npm script or similar) so I can trigger it myself whenever the codebase changes. • Hand back the processed files, the config/script you created, and a short read-me on how to rerun everything. I don’t have firm exclusions yet, so we can review th...
