    I want a skilled manual QA to put the product search and filtering flows of my e-commerce website through their paces. The job is entirely web-based; no mobile or desktop builds are involved. Your mission is to explore every way a shopper might look for an item—simple queries, multi-word phrases, misspellings, price and attribute filters used alone or in combination—and confirm that the site returns the right products, respects sort orders, and never breaks the user experience. Edge-case behaviour, UI consistency, and any performance hiccups you uncover matter just as much as outright functional bugs. Please document issues clearly with steps to reproduce, expected vs. actual results, screenshots or video when helpful, and a severity rating so I can triage quickly. A short su...

    I need a Uniswap V2–inspired smart contract that focuses purely on token swapping. The contract should mirror the core swap mechanics—constant-product market-making, support for fee collection, and on-chain price querying—while omitting any extra yield-farming or liquidity-mining layers. Target chains The solution must compile and run on Ethereum mainnet, Binance Smart Chain, and Polygon without code changes beyond network addresses. Hard-coding of chain IDs is fine so long as they can be set during deployment. Technical expectations • Language: Solidity ≥0.8.x • Tooling: Hardhat or Foundry for compilation, testing, and deployment scripts • Gas considerations: match or beat Uniswap V2 swap gas where possible • Security: re-entrancy p...

    I’m running Odoo 17 on a DigitalOcean droplet and need to move everything—mainly our three POS registers—to a fresh Odoo Pro instance hosted by Odoo itself. The switch has to happen after business hours so we can trade the very next morning without a hitch. Here’s the scope: • Set up the latest Odoo Pro environment and replicate all current data (products, customers, POS history, accounting, etc.). • Schedule and execute the migration in the evening, handle DNS or domain changes, and verify that we’re live before opening time. • Fix the two pain points inside POS: receipts occasionally refuse to print, and opening balances aren’t resetting to zero at shift start. • Make sure dual-currency works flawlessly—XCD at 0.40 is ...

    My autonomous surface boat is already fitted with an onboard computer and telemetry radio, and I have written a custom Ground Control Station from scratch. Mavlink packets are moving in both directions, but several key features are still incomplete, preventing the vessel from running fully untethered. What still needs doing • Navigation & waypoints – clean, reliable mission upload/download, in-app editing, and live progress feedback. • Remote control & monitoring – rock-solid RC override, real-time telemetry (battery, GPS, attitude, speed) and an alert system when any parameter drifts out of range.

    My br2.0 Bridge base wallet runs for a while and then throws unexpected errors that crash the application outright. Transactions, sync, and startup all behave normally up to that point—the problem is the sudden, repeatable crash that interrupts everything afterward. I need someone who already understands the br2.0 code-base (or is comfortable reverse-engineering it), can replicate the fault on their own machine, locate the root cause, and deliver a stable build. If you can implement automated tests or logging to prove the fix is solid, even better.

    For the next 45 days my real-time multiplayer card-game site will be running live and I need a reliable developer who can jump in quickly, squash bugs, and polish the experience without disrupting active players. Bugs currently reported range from gameplay logic hiccups to interface glitches and the occasional performance dip under load. Alongside the fixes, I’d like several small but high-impact changes rolled out: a couple of lightweight new features, some UI/UX refinements, and periodic content tweaks that keep the lobby fresh. Nothing massive. iPad users account for a healthy slice of my audience, so part of the brief is to tighten up responsive layouts and squeeze extra performance on iOS Safari—especially during swipe and drag card actions.

    Our IntelliJ-based automation framework (Cucumber + Java + Selenium WebDriver, built with Maven) has started reporting red where it should be green. Most of the noise comes from step definition errors, with a few stubborn XPath locators and the usual timing quirks. We run everything through a single Maven command, so once a test breaks it blocks the whole pipeline. What I need you to do • Pull the current project and review how the glue code, feature files, and runners fit together. • Pinpoint and repair the failing step definitions. • Verify every XPath locator still maps to the DOM; update if the application under test has drifted. • Add or refine waits and other synchronization utilities so the suite is stable, yet keep the existing package structure untouch...
