Unlimited People-Search Scraper App(Python)

I’m building a tool that lets me pull every possible result from FastPeopleSearch.com and TruePeopleSearch.com without hitting their normal roadblocks. The app must run on webpage but be operated through a clean web-based interface I can open in a browser. Core expectations • An AI component that takes a partial or full name and automatically generates smart variations to feed the two sites, maximising hit rate. • A robust anti-detection layer that bypasses captchas and avoids IP or rate-limit bans (rotating residential proxies, headless-browser fingerprint control, and any other technique you consider reliable). • Automatic capture of every returned record—addresses, phone numbers, emails, relatives, whatever is shown—then saving it to a local database so I can filter or export later. The workflow should feel simple: I enter a seed name, watch the suggested variations run in the background, and then browse or download the compiled results inside the same web UI. Deliverables • Windows-based service or executable with embedded web UI • Documentation for setup, proxy configuration, and routine maintenance • Final test demonstrating unlimited query runs over several hours with no captcha interruptions or bans If you have solid experience scraping protected sites, handling captchas, and weaving AI into search automation, I’d love to see how you would tackle this.

Simple Power Apps Canvas App using one SharePoint List

I need someone to help build a simple Power Apps Canvas App for a production works order tracking process. The app is for a small engineering company and will be used on shared Android tablets and mobile phones. This is for a **simple, but modern look first version** that I can expand later. ## What the app needs to do Operators need to: 1. Select a workstation / production area. 2. Scan or type a works order number. 3. Add multiple works orders into a batch. 4. Review the batch. 5. Submit the batch. 6. Save the submitted records into one SharePoint List. 7. View recent submitted records. ## Data source The app should use **one SharePoint List only** for the first version. Example list name: WOTracking No Dataverse, SQL, Power Pages, model-driven app or premium connectors unless agreed first. Suggested SharePoint columns The single SharePoint List can contain: * `Title` — works order number * `TrackArea` — workstation / production area * `TrackDateTime` — date and time submitted * `TrackDate` — date only * `TrackTime` — time only, text format such as `HH:mm` * `TabletID` — tablet/device name if available * `InputMethod` — typed / scanner / batch * `BatchID` — ID to group one batch submission * `SubmittedBy` — user who submitted * `Comment` — optional notes ## Required screens First version only needs: * Home page * Works Order Tracking * Batch Review * Submit Result * Latest Updates ## Main screen The Works Order Tracking screen should include: * workstation selector; * works order input box; * Add to Batch button; * batch list/gallery; * remove item from batch; * clear batch button; * review/submit button. The important part is that the operator can select the workstation once, then scan/type several works orders before submitting. ## Submit logic When the batch is submitted: * add one row per works order into the single SharePoint List; * include the same `BatchID` on each row in that submission; * include the selected workstation/area; * include date/time submitted; * show a success/failure result. ## App style The app should be: * simple; * tablet-first; * mobile-compatible; * large-button; * easy for factory operators; * easy for an internal IT manager to maintain. Basic responsive layout is enough. It does not need to be overdesigned. ## Deliverables Please provide: 1. Working Power Apps Canvas App. 2. One SharePoint List connected. 3. Batch add/review/submit working. 4. Latest submitted records screen. ## Important This is for a first working version only. I want something simple that I can expand later. Future features may include current status, full history, error logging, Datafile ERP export, assembly instructions, stock locations, incident reporting and IT tickets, but they are not required now. Please confirm: * your experience with Power Apps Canvas Apps; * your experience with SharePoint Lists; * estimated cost; * estimated timescale; * whether you can keep this simple and use only one SharePoint List for the first version.

Shopify Developer & Design - product template + metafield system

We're an established UK online building-products retailer (large catalogue) levelling up our Shopify store, supplier by supplier. We're looking for a design-capable Shopify developer — someone who builds clean, well-structured Shopify and has a genuine eye for design. This first project builds the reusable foundation our whole catalogue will run on, then completes one product range (external cladding, ~11 products) as the gold-standard template. What the project involves: Set up a metafield + metaobject structure for product specs (material, colour, RAL, coverage, fire rating, dimensions, lead time, warranty) and per-brand info Build one flexible, well-designed product + collection template that auto-renders spec tables, a brand block, swatches and a coverage calculator from those metafields Configure storefront filters (Search & Discovery) from the metafields Add Product/Review schema and handle canonical/robots on filter URLs (no URL/handle changes — existing handles stay) Complete one cladding range end-to-end as the exemplar, including collection pages with auto-fill rules You must be able to show: Shopify metafield + metaobject experience Storefront filtering (Search & Discovery or similar) Liquid theme section development A portfolio of stores that genuinely look good, not just function Important: there's a design sign-off stage — you'll build the example product page in the template and we approve the look before go-live, as it becomes the template every other product inherits. Strong work leads to ongoing rollout across the wider catalogue at an agreed per-range rate. To apply, please include: Two or three Shopify stores you've built (ideally large catalogues with filtering) One line on how you'd structure metafields for a product that comes in multiple colours and sizes Your availability and rough timeline for a project of this size
