...back to the oldest iOS version still accepted by the App Store. • Background downloading: implement reliable, resumable downloads so users can leave the app while large files finish in the background. • No login flow: the app must work without any form of user authentication. • Local storage only: downloaded files are saved directly to the device’s sandboxed storage (Documents or Library/Cache—whichever you recommend for App Store approval). • yt-dlp backend: prepare a lightweight API layer that wraps yt-dlp, deploy it on my server, and tune the config to accept the maximum practical number of concurrent requests without timing out or rate-limiting. • Publishing: handle certificates, provisioning, App Store Connect metadata and TestF...
...occasionally crash, background data jobs stall, and some API calls crawl or return stale data. The core pain points are functionality errors and noticeable performance drops that show up in three critical areas—authentication, data processing, and every external API integration we rely on. I see everything from 500 errors to multi-second waits, and newly saved records sometimes refuse to surface until a cache clears. Here’s what I need from you: • Identify and eliminate the root causes of the crashes and data inconsistencies. • Tune the codebase and queries so response times feel snappy again. • Make sure fixes hold up under normal and peak load; automated tests or clear manual test notes are important. • Leave concise inline comments or...
...right after kickoff. Your task is to pinpoint why those image-based Telegram links fail and apply a clean fix that works across common Android devices. The site is powered by WordPress with LiteSpeed Cache, and my Core Web Vitals are excellent—LCP and CLS must stay at their current “perfect” levels. Please work within that constraint and test thoroughly before deploying any change. Key goals • Reproduce the crash, isolate the root cause, and explain it in simple terms. • Deliver a code or configuration adjustment that eliminates the crash without touching overall site speed or cache efficiency. • Confirm that non-affected Telegram links, other social shares, and normal page behavior remain intact. • Provide a concise repo...
...core PHP extensions that Magento 2.3.3 demands—no newer or older versions unless they match that requirement. • Install Magento 2.3.3, unpack my file archive, import the SQL dump, then resolve any configuration or compatibility errors until the storefront and admin panel both load without issues. • Performance-tune the environment: enable and configure Varnish for full-page cache, set up Redis for sessions and cache storage, and wire in Elasticsearch for catalogue search. • Check file permissions, cron jobs, deployment mode, and re-indexing so that the site survives reboots and continues to perform well. Acceptance is met when: 1. The site renders correctly over HTTPS on the VPS public IP (I’ll update DNS after). 2. Admin login, product...

Requirements: • Proven experience with tRPC and Drizzle ORM is mandatory. • Strong understanding of MySQL migrations to ensure zero data loss. • Clean, documented code...

...app – priority scope The passenger build must ship with: • Real-time bus tracking displayed on Mapbox maps • A smooth digital ticketing flow (QR / NFC hooks already in the API) • Trip planning that pulls live route and schedule data Mapbox is the mapping SDK of choice, so solid experience with its Flutter plugin is essential. You’ll wire up push notifications for bus arrival alerts, cache data aggressively for low-bandwidth corridors, and squeeze every frame you can out of the map view. After the passenger release we will iterate on driver and conductor apps that share the same design language and codebase; modular architecture from day one will make that hand-off painless. Deliverables for the first milestone 1. Flutter source code in a ...

I need a quick-turnaround PHP script tha...websites (no authentication required). The current feed I rely on has gone down, so this will act as an immediate rescue solution. Key requirements • Parse each site’s HTML/JavaScript to extract the latest price. • Merge the three readings into one final value (average or last-in wins—whichever is fastest to implement). • Refresh the value every 30 seconds and write it to a variable or simple cache file I can echo anywhere on my site. • Code must be plain PHP (I edit in Notepad++), well-commented, and ready to drop into an existing page. Timing is critical: I need the working script delivered within 30 minutes of awarding the project. If you’ve scraped live prices before and can jump on a scre...
...compact PHP snippet—just a few lines I can paste over the old ones in my existing file (I normally edit in Notepad++). Source: the price appears on a public webpage, not an API. I simply need to pull the current value (no history or extra metadata) and echo it on my page. Accuracy matters, so the script should refresh roughly once a minute; feel free to suggest a lightweight in-memory or file cache so we don’t hammer the remote host. Hand over: • A short PHP function that: – Requests the page with cURL or file_get_contents – Parses out the price reliably (DOMDocument, XPath, or a concise regex—whatever is most stable) – Returns the numeric value ready for echoing or JSON output • A sample cron entry (or JavaScript fallback) ...

I run the site and stale assets are becoming a headache. I need the current browser cache wiped clean and, more importantly, an automated way to force fresh files any time I push an update. That means setting the right cache-control headers, adding versioning where sensible, and giving me a simple repeatable method (script, task runner step, or server-side tweak) that keeps visitors from seeing outdated content. Key acceptance criteria: • Existing browser cache for all visitors is effectively invalidated the moment the solution is deployed. • Future releases trigger automatic cache clearing with no manual steps on my side. • Solution works across mainstream browsers and requires no plug-ins for the end user. • Clear, concise docum...

I’d like you to review the sync configuration for both platforms at the same time, ensure only the essential folders stay local, and confirm that SharePoint libraries linked through OneDrive are also syncing properly (they have been falling out of date).
