    I have a set of roughly 51 – 200 technical diagrams that must be fully prepared for computer-vision training. Each image needs three things: clear class labels, accurate bounding boxes around every object of interest, and pixel-level segmentation masks. You may work in any modern annotation platform you prefer—CVAT, Labelbox, VGG Image Annotator, or a comparable tool—as long as the final export is delivered in COCO JSON (or another widely used format we agree on before you begin). Consistency is critical; every diagram must follow the same labeling taxonomy and colour scheme so the dataset can be dropped straight into a model pipeline without extra cleaning. Deliverables • Labeled, boxed, and segmented versions of each diagram (51–200 images) • One...

Fast load times, smooth transitions and a clutter-free Material-compliant UI matter more to me than a long feature checklist. Key features and behaviours • Add, edit, archive and delete tasks locally (Room or Realm preferred, but I’m open if you can justify another lightweight on-device store). • Optional grouping or tag system so users can sort their list quickly. • Swipe or long-press gestures for common actions. • Due-date picker with basic notifications.

    I’m a newly minted Integration Engineer who wants to move beyond theory and get confident inside the Fiorano Integration Tool. To do that, I’m booking a focused, 60-minute video or voice session with someone who has real-world Fiorano experience and knows how to translate that knowledge to a beginner. During our call I’d like to walk through practical integration scenarios, then zoom in on the areas I find toughest—debugging, routing, selectors, XSLT flows, and the overall logic that ties a complete solution together. By the end of the hour I should not only understand what to click but why it matters in production.

    I already run a PAN-card portal and have obtained full documentation plus a live API key for the official Application API. What I now need is clean, well-tested code that plugs this API into my existing workflow so users can: • submit brand-new PAN applications • update records they have already started • pull back the latest application details in real time The API is REST/JSON and secured only by an API key, so no OAuth dance is required—just proper header handling and secure storage of the key on the server. I will provide the key, the docs, and access to a staging instance of the portal. Please wire the endpoints, map all responses to our current UI, build solid error/timeout handling, and give me a short read-me so future devs can follow the flow. Everyth...

    I maintain several production Laravel applications and regularly break the backlog into bites-sized sprints of five tasks. I’m looking for a reliable developer who can jump straight into the existing codebase and deliver new features only—no bug triage or code-review work for now. Here’s how we’ll work together: I assign a ticket, you push a clean, tested solution, and as soon as the task is accepted I release payment and move you to the next item in the batch. You’ll need solid PHP 8.x, Laravel, and Git workflow experience because you’ll be working directly inside the current repository. Clear commit history, adherence to existing coding standards, and concise pull-request notes are essential. If you enjoy short, focused sprints and the satisfacti...
