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...
Write a Windows application with the following objectives: Provide a highly visible, customizable mini on-screen keyboard - with ONLY: Controller keys (adjustable size, color, and placement). Purpose: Clicking on one or more controller keys has the effect of holding down the (physical) equivalent key(s) for the next or subsequent key presses. Design aspects to be agreed. Long term relationship is a key objective to enable high quality future development, including hardware keyboard integration, subscription-based monetization, and possible future expansion to a full keyboard with additional color configuration options.
I already have the basic Flutter codebase set up and compiling, but it needs that final round of engineering and UI love before it can ship. The app is a straightforward utility: a personal task manager whose standout capability is rock-solid task prioritization. Here’s what I need from you: • Review the existing Dart code, spot bottlenecks, and refactor where necessary so the project stays clean, null-safe, and on the current stable Flutter channel. • Finish the task-management workflow: create, edit, reorder, and archive tasks while letting users assign a priority level that drives list sorting. • Wire up local persistence with Hive or another lightweight store (open to your suggestion) so priorities stay intact between sessions. • Polish the UI with ...

The code should follow good object-oriented practices, handle exceptions gracefully and keep credentials secure. The immediate goal is to: • authenticate with my API key/secret and request token • subscribe to market data streams via WebSocket • fetch historical price data on demand • place, modify and cancel orders programmatically Please build the solution using the official kiteconnect Python package wherever possible, but feel free to improve on its abstractions if you can demonstrate clearer structure or easier reuse.

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...
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 want a LabVIEW-based curve tracer that mirrors the behaviour of the Digilent WaveForms instrument but runs entirely inside LabVIEW while talking to my Analog Discovery 2. The program must sweep a user-defined voltage across a device, sample the resulting current and voltage, and plot the I-V curve in real time. Primary test focus is on resistors, yet it should also cope with simple LED measurements so the code isn’t locked to a single device type. Please make the sweep limits and step size configurable so I can adapt quickly to different resistor values or LED forward voltages. The interface needs to feel as quick and informative as WaveForms, with one extra twist: I need reliable data-export options (CSV at a minimum) straight from the GUI so I can toss results into Excel or...
I need a concise, practical set of coding rules that zero in on secure-by-design practices. The end product should read like an internal standard any developer on my team can pick up and apply immediately, regardless of project size or framework. What matters most to me is clarity and real-world applicability: guidelines that flag common attack surfaces, prescribe safe patterns, and illustrate both “do” and “don’t” examples. Feel free to draw on OWASP, MITRE, or other respected references if they strengthen the reasoning, but every rule must be expressed in my own organisation’s plain language so it slots straight into a living style guide. Deliverables • A structured rules document (Markdown or Google Doc) covering secure coding practices from ...
I need a full-featured Video Management System that I can compile and run on a Linux environment. The solution must follow a clean server-client architecture, include 100 % source code, and scale reliably to at least 1 000 simultaneous camera streams drawn from a wide mix of global CCTV brands (ONVIF or equivalent interoperability is a must). Two core capabilities are non-negotiable: smooth multi-camera live view and fast, timeline-based playback of recorded footage. Everything—connection handling, recording, storage management, and UI—has to remain responsive even under heavy load. If you already support complementary functions such as motion-triggered recording or smart alerts, feel free to highlight them, but live view and playback come first. The initial focus will be on ...

I’m midway through a personal project and need a seasoned Python mind to guide me from solid intermediate skills to confident, production-ready code. I’m looking for help that spans the full spectrum: refining my grasp of core syntax, strengthening advanced design patterns and optimisation techniques, and making better use of popular libraries and frameworks that fit the project’s needs. Here’s what I have in mind: • Regular, live coaching sessions where we review my code, untangle issues, and discuss best practices. • Clear homework or mini–milestones so I can apply what we cover right away. • Practical walkthroughs of any libraries we decide to incorporate, plus advice on structuring the overall solution. The end goal is to ship this pro...
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...
I run a growing software-engineering team and need one strong English speaker here in Pakistan to become the voice of our project during client sessions. Your main responsibility is to deliver clear, confident project-update presentations that walk stakeholders through our software development processes, answer their follow-up questions, and capture any feedback for our engineers. Because the updates often dive deep into sprint metrics, pipelines, and architecture trade-offs, I’m looking for someone with advanced technical expertise—ideally a background in software engineering—who can switch effortlessly between layman explanations and low-level detail. This is a steady engagement structured around a monthly retainer of roughly $1,200. I’ll supply release note...
