    I need a reliable scraper that monitors every basketball league listed on Bet365 (). The script must do two separate pulls for each game: Objective 1 • Run #1 – as soon as Bet365 publishes the starting lineup. • Run #2 – again on game day, no later than one hour before tip-off. For each run, capture Teams and scores, all published lineups and odds, plus the Q1 Total, full Quarter and Half statistics as soon as they appear. The goal is to analyse how the line and odds move between the first and second snapshot, feeding a broader betting-strategy model, so accuracy and time-stamping are essential. Store everything in a structured database of your choice (PostgreSQL or MySQL are fine). The tables must let me query: • first-pull values • second-pull val...

    I am developing an end-to-end platform that pulls live claim-related data from Revit models, runs it through a FIDIC rules engine, and then immutably stores and certifies every step on Hyperledger Fabric.

I already know I want React for the client interface, so the build should follow best-practice component architecture, modern hooks, and a clean, responsive layout.

    I need a lightweight, browser-based application that lets customers quickly find and book trusted home-service pros—starting with cleaners—through a clean, Uber-style interface. The whole experience must feel effortless for users who may not be tech-savvy, so every screen has to be uncluttered, with large touch targets, clear typography and a gentle colour palette. Core workflow • A new customer lands on the site, registers with a phone number and receives an SMS code to verify the account. • They browse service-provider cards that show a photo, short bio, skill tags and an aggregate star rating pulled from past jobs. • From the same view they tap a date/time slot, confirm the booking and immediately see it in their personal schedule. • A lightweigh...

    My small team already feels comfortable moving around Odoo, but we need a deeper, hands-on grasp of its advanced features—specifically within the Inventory and Manufacturing apps. The aim is to master topics such as multi-warehouse routing, replenishment automation, serial/lot tracking, BOM management, work-center scheduling, and related reporting so we can run our operations without outside help. What I need from you is a structured yet practical learning experience that walks us through real use-cases in our own staging database, builds muscle memory through exercises, and leaves us with reference materials we can revisit later. Deliverables • Training agenda tailored to our current workflow • 4–6 live interactive sessions (screen-share or similar) for up to fiv...

    I’m ready to commission a custom PostgreSQL-based system that brings four critical workflows into one place: • Inventory control with real-time stock level monitoring and fast barcode scanning for check-in / check-out. • Employee schedule management so I can see who is assigned to each job at a glance. • Job costing and progress tracking that ties labor, materials, and overhead together for accurate profitability insights. • A secure API endpoint that pushes material usage from each job directly into QuickBooks, eliminating double entry. You will design the data model, build the web interface (any modern stack you’re comfortable with), and implement the QuickBooks integration.

    I need a backend engineer to turn my spec into an MVP that exposes a clean, API-first trust and reputation service for autonomous AI agents. The entire product lives server-side—no front-end work at all—so every feature must be reachable through intuitive, well-documented endpoints. Core requirements • Stack: your choice of FastAPI (Python) or Node (TypeScript), backed by Postgres, containerised with Docker, and wired to Stripe for billing events. • Auth: simple, robust API Key flow; keys must be generated, stored, and validated on every request. • Scoring logic: compute each agent’s trust score solely from its interaction history, according to the formulas in the spec. Performance metrics or direct user feedback are outside this first iteration. ...

    I have the backend, APIs, and a clear visual direction in place; what I still need is the full React-based frontend for a web-first laundry administration and point-of-sale system.
