Depuração Jobs

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...

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...

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...

Tareekh – Multi-Calendar & Cultural Calendar App Tareekh is a modern Flutter-based calendar application designed to bring different calendar systems, seasonal changes, and cultural information together in one simple and easy-to-use mobile application. The idea behind Tareekh was to create something more meaningful than a basic calendar. Instead of simply displaying dates, the application combines Gregorian, Hijri, and Punjabi calendar information with seasonal changes and cultural elements. The application has been developed as a real-world mobile product and is currently live on the Google Play Store. Main Features Multiple Calendar Systems Tareekh supports multiple calendar systems within a single application, making it easier for users to view and understand dates accord...

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...

My e-commerce site ( ) is throwing up a few headaches I’d like cleaned up quickly. On several product pages and on the contact page I’m seeing broken links and intermittent PHP error messages. The layout itself is fine, so the job is strictly about tracking down the faulty code or routing, correcting it, and confirming no new errors crop up once the fixes are deployed. You will need to: • review the existing PHP templates and any related routing/controller files • repair or correctly redirect the broken internal links on the affected pages • eliminate the current error messages so the pages load cleanly • test across desktop and mobile to be sure every link resolves and no new warnings appear I’ll give you access to the codebase and the live...

I need a Verilog-HDL RAM module that meets an already defined specification. The core requirement is a synchronous memory unit with reliable read/write control. Beginning from the RTL, I want clean, synthesizable code, followed by a self-checking testbench that proves functional correctness across corner cases. Your workflow should include: • RTL implementation of the RAM with parameterised depth and width • A functional testbench that drives realistic stimuli and automatically flags mismatches • Simulation runs in ModelSim or an equivalent simulator, with waveform capture for review • Iterative debugging until the waveforms reflect the expected behaviour • Concise documentation explaining interface signals, timing, and any design decisions Address decodi...

I’m looking for an experienced C++ developer who is comfortable working in a Linux environment to track down and resolve a functionality bug that’s affecting one of my applications. The codebase already compiles and runs; however, a key feature is not behaving as intended. Here’s what I need: • Investigate the source to identify the root cause of the malfunction. • Provide a clean, well-commented patch or pull request that addresses the issue. • Supply build instructions (Makefile or CMake) and any test cases you used to verify the fix. • Include a concise summary of the changes so I can follow your logic. The project does NOT require UI tweaks or performance tuning—just a solid functionality repair. You’ll have SSH or Git acces...

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. The goal is straightforward: once the operator presses START the line should sequence itself, react to its sensors, and shut down safely on faults or an E-Stop, all while remaining easy to troubleshoot. Hardware and software already on hand: 1- allen bradley 5069 l330er • CompactLogix controller with standard 24 V DC I/O cards • A mix of photo-eyes, limit switches and VFD-driven motors • Studio 5000 Logix Designer for programming What I expect from you • A clean, well-commented .ACD project file written in ladder logic • Tag database and I/O map that match my wiring • Brief...

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...

I run , a WordPress-WooCommerce store for LDV car parts. Stock control is handled with the ATUM Inventory Management plug-in and payments go through the TYL banking gateway.
 Lately, confirmed buyers hit “Place order” only to meet a technical/server error and the transaction stalls. No payment is captured, no WooCommerce order is created, and our stock levels stay unchanged. The error messages appear in the browser and in the WooCommerce logs, so we know it’s not a silent failure—yet my part-time techs haven’t been able to trace the root cause. Here’s what I need: • Diagnose why WooCommerce is blocking or timing-out at checkout. • Pinpoint whether the fault lies in the theme, the ATUM plug-in, TYL’s API, or server configuration (PHP...

I need a skilled React developer to jump into my existing code-base and complete a new feature from concept to merge-ready pull request. The exact area—whether state management, hooks, or a UI component—will be clarified as soon as you come aboard, but you should be comfortable working across a typical modern stack that includes React 18, functional components, and JSX/TSX. Here’s how I picture the collaboration: • First, you review the current repository, ask any clarifying questions, and outline a concise plan for the feature. • Next, you implement the solution in clean, well-commented code, following our linting rules and component structure. • Finally, you supply a PR with passing unit tests and a short hand-off note so I can verify, merge, and de...
