I’m looking to harden our Wide Area Network against the latest JADEPUFFER strain that is exploiting unsecured endpoints. The immediate priority is network-level vulnerability mitigation; we have already confirmed that these endpoints are the entry point for the threat. While spear-phishing defenses and general malware scanning remain on our roadmap, the focus right now is a purpose-built neutralization layer that can out-adapt the attacker’s tooling. Here is what I need built and handed over: • A modular “shell-buster” utility written in Python and ShellScript that detects, contains, and disables JADEPUFFER artifacts on any endpoint connected to the WAN. • A lightweight GENAI / LLM component that continuously learns from captured payloads, updating det...

Our live React Native app needs a focused round of maintenance to bring it back to peak shape on both Android and iOS. Tasks waiting on your desk: • UI & Navigation — squash the layout inconsistencies, navigation bugs, and any mis-aligned elements so every screen looks and flows identically across devices. • API Layer — trace and correct the data-fetching issues, authentication errors, and endpoint response mismatches that are blocking a clean handshake with our Node.js back end. • Firebase — resolve the lingering authentication and notification bugs to restore a seamless sign-in experience and dependable push messaging. • Performance & Stability — profile the build, eliminate obvious bottlenecks, and make sure the app remains stab...

I have a 16-channel relay board that must be driven by an Arduino. Each of the sixteen micro-switch inputs will correspond to one—and only one—relay output. When a switch is pressed the matching relay should energise for a fixed pulse of 2-3 seconds, then drop out automatically; there is no need for the user to alter that timing. Here is what I need from you: • Clean, well-commented Arduino sketch that reads the 16 discrete inputs, debounces the switches, and fires the appropriate relay for the required duration. • Pin-mapping and a simple wiring diagram so I can connect everything without guesswork (I will be using a common 16-relay module that accepts active-LOW signals, but please keep the code flexible enough to invert logic if needed). • Guidance on a...

I need an experienced embedded hardware / PCB engineer to design a production-ready STM32-based main controller PCB for a therapeutic massage/spine bed system. This is a build-to-spec project. I already have a detailed engineering handoff package including system architecture, old PCB references, estimated current budget, pin maps, connector notes, BOM guidance, firmware handoff notes, layout requirements, and test plans. The freelancer’s main responsibility is hardware design and manufacturing outputs: schematic, PCB layout, Gerbers, BOM, assembly files, and firmware-ready hardware documentation. Firmware will be developed separately using AI/Codex/Claude from existing working ESP32 firmware. I will burn the firmware once the board is ready. The PCB must support first firmware flash...

My VBA-driven workbook suddenly throws an error on Windows 11 with Office 2019. I need someone who can jump in right away, locate the glitch, and patch it within the next couple of hours. I will send the workbook and a brief note on the steps that trigger the failure. Once you reproduce the problem, please clean up the code, make it robust for this environment, and send the corrected file back along with a short summary of what you changed and why. Deliverables • Repaired Excel file with fully functioning macro • One-paragraph changelog outlining the fix If you are confident with VBA in Office 2019 and can start immediately, this should be an easy win for you and a quick resolution for me.

My single-product page suddenly looks scrambled—elements overlap, fonts jump in size, and the spacing that used to keep things tidy is gone. The core site runs on WordPress with WooCommerce, and the only urgent task is to bring that layout back to its clean, responsive state. Here’s what I need you to do: • Inspect the current product-page template, trace the exact source of the broken layout (CSS conflicts, stray divs, outdated template overrides, or plugin/theme clashes). • Apply clean fixes—preferably in a child theme or custom CSS/JS—so the header, gallery, description, price, and Add-to-Cart section snap back into proper alignment on both desktop and mobile. • Verify the solution across the latest versions of Chrome, Firefox, Safari, and E...

Our consultation form is powered by Contact Form 7 and it’s currently failing to deliver submissions. Visitors complete the registration screen, hit the submit button, and nothing reaches our inbox or database—no success message, no error prompt, just confusion. I need you to step in, trace the issue, and restore a friction-free flow. Here’s what I expect: • Diagnose the root cause inside WordPress, paying close attention to Contact Form 7 hooks, JavaScript validation, and any theme or plugin conflicts. • Repair the submission logic so every valid form reliably reaches the designated email (and any additional endpoint we configure). • Add clear, user-friendly feedback on success and on any validation problem, instead of the silent failure we have now....

My Flutter-based loyalty app has been live on both stores for just over three months. Everything runs smoothly on Android, but on iOS the user-login functionality suddenly stopped working: as soon as a customer submits their credentials an error message pops up and the flow halts. I have a screenshot of the exact message ready for your reference. I need the login issue isolated, fixed, and pushed to the App Store as an expedited update. Beyond this immediate task, I’m looking for someone interested in an ongoing collaboration to handle future maintenance and feature expansion, so writing clean, well-commented code and documenting any changes are important to me. Key deliverables • Identify the root cause of the iOS login error • Implement and test the fix on the curre...

I need a complete system design and architecture for a Windows-only desktop application that will serve as a data-management solution. The core goal is to let end-users capture, organise, search and report on medium-to-large datasets through a fast, intuitive interface. Scope of work You will start from a blank slate, so the engagement covers everything from choosing the tech stack to defining the database schema, component boundaries, communication patterns and deployment strategy. While I am leaning toward a modern .NET (C#/WPF or WinUI) approach, I am open to alternative frameworks such as Electron, Qt or JavaFX if you can justify clear performance and maintainability advantages. Key activities • Draft high-level and low-level architecture diagrams (layered architecture, modu...

I have an existing Chrome-based automation script that suddenly stopped behaving as expected. It is supposed to fill out forms, click buttons, and move smoothly from page to page, but it keep getting 403. Your task is to dig into the code, and get everything running flawlessly again. You are welcome to work in the same language and framework already used—if you are comfortable with Python + Selenium, Playwright, or Puppeteer, that is ideal. I will give you: • The current source and a short video showing the failure points • Test credentials and URLs for each flow the bot must complete Deliverables: 1. A corrected, fully functioning bot script. 2. A concise change log explaining what you fixed or refactored. 3. Quick setup/run instructions so I can verify on my ...

We have an Android app (TC58) that prints ShipStation shipping labels (4x6 PDF) to a Zebra mobile printer over Bluetooth.

## Fix Two Mobile Shopify Issues — Kalles Theme / Avada Conflict Investigation **Website:** []() **Shopify theme:** Kalles **Relevant apps:** Avada and other third-party apps may be involved This project covers **two separate mobile issues**, each with its own milestone. ### Milestone 1 — £60 ## Fix Shopify Inbox on Mobile The Shopify Inbox chat icon works correctly on desktop. However, on my **iPhone 13 Pro Max**, the Inbox icon is visible and appears clickable, but the chat window does not open in either: * Safari * Chrome Other developers have sometimes been able to open it on their own devices, which suggests the issue may be intermittent or dependent on device, browser, script timing, caching or app-loading conditions. Shopify Support suggested that the pro...

I run a classic ASP, SQL-driven site on a shared-hosting plan. Everything works until a visitor clicks a particular link whose destination is stored in the database—at that moment the browser returns the generic “500 – Internal server error.” I need someone who knows the quirks of legacy ASP on shared IIS environments to trace the fault, explain the root cause, and guide me through (or implement) the fix without upsetting the rest of the application. You’ll probably want to: • turn on friendly-error detail, check IIS logs and SQL traces • review the query and any redirect or response headers tied to that stored link • patch the offending script or database record, then verify the page now loads cleanly Deliverables 1. Short diagnostic ...
