    I need help collecting a clean, well-structured list of Twitter accounts that consistently post about AI and possibly category of AI (open source, ML, AI, general AI) Instead of handing you a fixed list, I’ll define the selection rules (for example: minimum follower count, specific AI-related keywords, recent activity, etc.) - min follower count 5000 and have alteast multiple posts with 100+ likes/ retweets.

From the ground up I need: • Product catalog management that supports advanced inventory with variants (sizes, colors, bundles, etc.) • A smooth shopping-cart experience tied to a secure payment gateway • A fresh, custom design—there’s no existing wireframe, so you will shape both the look and the structure You’ll own the Medusa server configuration and extend it where necessary for variant logic, stock tracking, and order flows.

    My stock-trading web app is showing real-time prices that don’t match the figures streaming through my broker’s terminal. The terminal’s feed is correct; the web app injects incorrect numbers and they drift further off the longer the session stays open. I need someone who has already debugged exchange or broker APIs, websocket feeds, or similar market-data pipelines and can pinpoint why the values pushed to the browser diverge. You may have to inspect the feed handler, caching logic, time-sync, or any rounding and conversion routines in the JavaScript front end as well as the server-side code. Acceptance will be simple: with the fix in place, the web app must display the same tick-for-tick price as the broker’s terminal during a live market session. If you&rsquo...

Please build the site in a modern, mobile-first framework, connect the map overlay for live updates, and keep the interface clean and fast. An admin panel where I can update routes, fares, and driver status is essential. Once the site is live, I need you to handle the full on-page optimisation—meta tags, schema for local business, page speed tweaks—and kick-start an off-page strategy that targets local search terms like “airport cabs” and &l...

    My Shopify store sells digital, downloadable religious artwork and I already set up a Google Marketplace (Merchant Center) account so I can start advertising. The snag is at the very first step: when I connect the Google Marketplace sales channel inside Shopify I get an “authentication failed” message and the process stops. I have not yet used any of the official troubleshooting guides from either platform, and the store is running on a clean theme with no custom code or third-party apps installed, so the cause should be straightforward. I can provide the exact wording of the error and full access to the Google Merchant Center and Shopify admin as soon as we begin. What I need from you: • Identify the root cause of the authentication failure and apply the fix insid...

    I need a Google Cloud / BigQuery specialist to stand up an end-to-end, webhook-driven data ingestion pipeline running in our production environment. When our external form system fires a webhook, your Cloud Function (or equivalent service) should capture the JSON payload, write the untouched record to a raw BigQuery table, then immediately process it. The processing step must • parse any nested JSON, • flatten and clean each answer field, • split the results into two purpose-built reporting tables, and • guarantee idempotency through a hashing technique that blocks duplicates. All components have to be secure, version-controlled, and able to scale with traffic spikes. This is strictly a backend/data-engineering job—no UI work is involved.

    I actively trade on TradingView and already rely on several open-source indicators plus one proprietary strategy. I now want everything wrapped into a single, coherent Pine Script that can place live orders with clear risk controls. Here is the core of what I need: • Combine my existing indicators and closed-source strategy into one script. • Let me toggle long/short entries, position size, and multi-time-frame confirmation directly from the script settings. • Include editable take-profit, stop-loss, and trailing-stop parameters so I can fine-tune risk on the chart without rewriting code. • Make the script broker-agnostic but capable of routing trades to futures, commodities, stock, and crypto brokers supported by TradingView’s Trading Panel or webhook/API ...

    I need a reliable system that can take our prepared text and video assets and publish them automatically across multiple social networks. After our kickoff call I will share the exact platform list and credentials, but the solution should be flexible enough to add or remove channels without major re-work. Key objectives: • Configure multi-platform auto-upload through Comet, mapping captions, thumbnails, tags, and any platform-specific metadata. • Create scheduling rules so each post goes live at the time I set—daily, weekly, or according to custom calendars. • Build a distribution workflow that queues content, validates it against each API’s limits, and triggers retries on transient errors. • Add an error-detection layer with clear logging and alerts ...

    I’m looking for a small, no-frills tool that I can spin up on a Linux VPS and use to blast out a single message to every recipient listed in a CSV file.

    I store a rapidly growing catalog of images and videos and need them delivered at lightning speed through Cloudflare’s infrastructure. The task is end-to-end: stand up a Cloudflare R2 bucket, wire it to Cloudflare’s CDN, and make sure the whole pipeline is ready for very-frequent traffic without surprise bandwidth costs. The work involves: • Creating and configuring the R2 bucket with public read access, optional signed URL support, and sensible lifecycle rules. • Connecting that bucket to a custom domain (e.g., ) using either the native R2 → CDN route or a lightweight Worker, with HTTP/3 enabled. • Tuning cache and Edge TTL settings so my media is served globally with minimal latency while allowing instant purges when a file is replaced. • S...
