Our industrial-grade controller combines a microcontroller core with supporting FPGAs, and the current firmware (running on an ARM Cortex-M3/M4) needs expert attention. I have several issues to resolve—intermittent peripheral hangs, timing glitches in high-speed I/O, and a few missing features that must be added without disrupting production uptime. Scope of work • Analyse the existing codebase, identify root causes of the observed faults, and document findings. • Refactor or patch the firmware so it runs reliably on the Cortex-M3/M4. • Optimise interrupt handling and DMA transfers where latency is critical. • Provide clear, commented source code plus a concise change-log so the in-house team can maintain it.

I’m expanding a high-performance computing initiative and need seasoned C/C++ talent to squeeze every last cycle out of our code. The core of the work revolves around designing, profiling, and hardening parallel processing routines that will run on Linux/Unix clusters. You’ll be free to choose the right mix of pthreads, OpenMP, MPI, CUDA, or similar frameworks as long as the end result is fast, deterministic, and fully verifiable. Here’s the environment you’ll step into: a mature codebase written almost entirely in modern C and C++, backed by rigorous data-structure design, multithreaded execution, and an SDLC that values deep debugging over quick patches. I handle planning, testing resources, and CI; you focus on writing clean, well-documented modules and driving ...

I’m building a converter that mirrors the behaviour of LeechCore, letting a physical PCIe device carry out high-speed DMA into or out of a KVM/QEMU guest while the host keeps full control. The job is to design and code the complete data-path: a small Linux kernel module (or VFIO extension) that exposes the device’s BARs, plus the matching QEMU patch or user-space helper that maps those DMA buffers safely into the virtual machine. You will decide the cleanest architecture, write the low-level C code, and supply a working proof-of-concept on an up-to-date kernel/QEMU stack. I expect well-commented source in a Git repo, clear build scripts, and a short demo showing a guest performing DMA transfers without crashing or corrupting memory. Deliverables - Kernel-side driver or VFIO...

My Shopify website has a performance/compatibility bug specifically when opened through the Instagram or Facebook in-app browser or meta ads. The site becomes extremely slow and buggy, while it works perfectly when opened directly in Safari, Chrome, or other browsers. I need someone experienced with Shopify and Meta in-app browser/WebView debugging to identify and fix the issue.

I have a dynamic list that occasionally comes through empty, and I want to be sure that, as items get added, every single entry respects one rule only: Specific length — each item must be less than 10 characters long. No other constraint (duplicates, numbers, etc.) matters for this task; I simply need reliable length-checking before an element is accepted. Please deliver a small, clean utility or function (Python, JavaScript, or any language you prefer) that: • Accepts raw user input or an existing array/list • Verifies each prospective item is under 10 characters • Blocks or flags anything that exceeds that limit, ideally returning a short reason so I can surface it in a UI later Include concise inline comments, a brief read-me showing how to run or import th...

I’m building a battery-powered prototype around an ESP32-S3 and need a rock-solid wiring diagram before I assemble anything. Once we start, I will share a complete list of sensors and modules, but you can assume they will be driven from a 9 V rail that must be stepped down where necessary. My priority is clear pin assignments, clean power routing, and reliable level-shifting so every device behaves exactly as intended. Your task • Draw a schematic / wiring diagram that shows every connection between the ESP32-S3, the sensors, any required regulators or level-shifters, and the battery interface. • Specify the exact GPIO pins you choose for each signal and explain any rationale or constraints. • Indicate decoupling, protection components, and connector types where...

I need Google Tag Manager installed from scratch on a custom-built HTML/CSS/JS site and configured so that I can finally see the actions that matter inside Google Analytics 4. The two events I must capture right away are: • Button Clicks – every primary CTA across the site • Payment Processed – a single conversion event that fires after a successful checkout Once GTM is live, the container should include all necessary tags, triggers and variables, with a tidy workspace and clear naming conventions. Please link the setup to my existing GA4 property, publish in the live environment, and supply a brief hand-off doc or Loom walkthrough so I can verify and maintain the configuration. Acceptance criteria • Both events appear in the GA4 DebugView and Real-Time re...

VS Code on my Windows machine became mis-configured after a failed uninstall/reinstall, and my STM32F4 board will no longer enter a debug session under the latest stable Zephyr. Compile and flash still work, so the tool-chain is there; it is the IDE integration that is broken. The session will be live over a screen-share, so you will walk me through: • Cleaning up every leftover piece of the previous VS Code + Zephyr install. • Re-installing VS Code in a way that matches Zephyr’s recommended layout, adding the correct extensions and CMake/West integrations. • Restoring full build-flash-debug capability for the STM32F4 kit, including OpenOCD/GDB settings and launch configurations. • Confirming that my earlier PowerShell-based Zephyr install, located in a ...

My ESP32 Dev Module refuses to return anything when I send AT commands to a SIM800L red board. The wiring follows the usual guides: GPIO27 to the SIM’s RX, GPIO26 to its TX, grounds tied together, the SIM powered directly from a single 18650 cell. I’ve triple-checked every jumper and even dropped a 1 kΩ resistor on GPIO27 and a 2200 µF capacitor across the SIM’s Vcc–GND rails—still silence. I’m compiling the sketch for the standard “ESP32 Dev Module” target in the Arduino IDE and the board is on a direct USB cable to my laptop. Serial monitor shows the commands leaving but not a single character coming back. If you know this pairing well, I’m looking for hands-on guidance that quickly pinpoints what I have overlooked&mdash...

I’m handling several production-level micro-projects that need immediate attention and clean, review-ready code. The work ranges from creating modules from scratch to refining existing features and squashing bugs, and I want everything delivered through GitHub—no ZIP files or offline dumps. Because I lean heavily on AI tooling in my own workflow, you’ll need active access to both OpenAI Codex and Claude so you can keep pace with the fast iterations I expect. The primary focus right now is green-field coding, but feature extensions and debugging tickets come up daily, so flexibility is essential. Core expectations • Push to a dedicated branch, open a clear PR, and respond to review comments quickly. • Maintain production standards: linting, unit tests where s...

I already run a terminal ZIP utility on Windows, and it does its job well. The task now is to weave in an EIP layer so the same command-line “terminal zip” workflow keeps working but the overall speed—measured in pure milliseconds—drops significantly. You will receive the current source/binary plus sample archives. Your role is to analyse the bottlenecks, introduce EIP (whether that means a new library, multithreading, hardware-assisted calls, or any smarter technique you recommend), and return a version that produces identical archives while completing the job faster. Deliverables • Optimised ZIP solution with EIP integrated and ready for Windows terminal use • Before-and-after benchmark in milliseconds proving the speed gain • Brief build/ru...

Após atualizar meu projeto Java no NetBeans, passei a enfrentar erros de lógica que impedem o correto funcionamento do sistema de notas fiscais. O principal ponto crítico é o cálculo de impostos; algumas classes deixaram de se comunicar entre si e os resultados agora divergem do esperado. O que preciso: • Revisão do código para identificar e corrigir todos os erros de lógica introduzidos após a atualização. • Restauração do fluxo de comunicação entre as classes envolvidas no cálculo de impostos. • Testes unitários ou de integração que comprovem o funcionamento correto dessas rotinas. • Ajustes pontuais em outras partes afetadas, caso desc...

I run a complex System-on-Chip project and reserve about four hours each week for focused progress. During that window I rely on an experienced engineer who can jump straight into SystemVerilog / UVM code and keep our verification flow tight. The core of the session is SoC-level development with specific focus on PCIe, DDR, and GPU SoCs, yet every task circles back to solid design-verification practice: • Testbench development that plugs cleanly into our existing UVM environment • Live simulation and debugging, spotting corner-case failures as they appear • Coverage analysis and closure so we meet functional goals with data-driven confidence Remote pair-programming over a shared workspace works best for me; I’ll have source, waveforms, and spec documents ready...

I need a sharp-eyed GoHighLevel specialist to jump in and straighten out a handful of misbehaving automations. The most urgent pain point is tag management— some contacts are picking up the wrong labels, while others get none at all—so your first task will be to audit every tag rule, make corrections, and confirm the right tags fire at the right stage. Beyond that, two things are breaking the experience: certain workflows refuse to trigger when they should, and a few older automations appear to be clashing or duplicating actions. I’d like you to trace each workflow from opt-in or payment through to the final email, remove or merge anything that conflicts, then run end-to-end tests to prove everything now fires cleanly. Deliverables: • Corrected tag logic applied ac...

I have built a small C# IDE with Avalonia where users can either type code directly or double-tap a method in the tree view and edit that method visually through a CodeEdit UserControl. After refactoring the original TabControl into its own UserControl (so multiple CodeEdit instances can sit in separate tabs), the tabs open but every CodeEdit surface is blank. No exceptions are thrown and the debug output stays clean; the method list itself still populates in the tree view exactly as before. The task is simple but surgical: trace why the selected method’s code is no longer passed into the CodeEdit UserControl after the TabControl-to-UserControl move, and restore the previous behaviour. I expect you to diagnose the binding or data-context issue, patch it, and confirm that: • Do...

I’m expanding a large-scale IBM i modernization program and need 15-20 seasoned engineers who can hit the ground running this week. Every member of the squad must be equally comfortable in RPGLE and DB2/400, COBOL/400 and CBLLE, plus SQLRPGLE and SQLCBLLE; this is non-negotiable because the codebase spans all those languages. Day to day you’ll design and refactor triggers and stored procedures, keep our repositories clean with Git, and write repeatable unit tests against DB2/400 using the standard IBM i testing frameworks. We work entirely in Rational Developer for i, so an intermediate command of RDi shortcuts, debuggers, and plugin management is essential. The environment runs on IST hours, fully remote, with an initial six-month horizon and clear funding to extend well bey...

I have an Allen-Bradley CompactLogix processor installed at my facility in Ridgefield, NJ 07657 and I need a ladder-logic program that fully automates our conveyor line system.

My application relies on Apache PDFBox for generating and displaying PDFs, but the current build renders pages with an incorrect layout— it renders over other components in user interface. I need a developer who knows the internals of PDFBox, its Renderer (PDPageContentStream, PageDrawer, etc.), and the Java graphics pipeline to identify and patch the root cause of this layout problem. The problems is related to -method. It may be reproduced by adding a JSplitpane into a JFrame, then rendering to the left component. It renders over the right component, too. It is wrong. It also relates to PageDrawer and its setClip() -method. Even if we apply the initial clip, it still renders wrong, see code below. AffineTransform at = (); (); Shape shape = (initialClip); (shape); Moreover, if w...
