    ...using the 2 csv files below. Don't waste your time unless you are a talented and naturally born graphic designer. I am not interested in regular designs. I need the design to look like it was made by a professional designer. For example, check out carousel-1080x1350.html. I asked Claude to design this in HTML. I can load HTML into Canva, but it's not very editable. I can also ask Claude to design in Canva, but it doesn't come out this nice. So I need a creative designer to help. I will pay you $1500 for this job. But you have to show me something first. I know that 99% of the freelancers who will bid, don't have the graphic design skills needed for this project. So only apply if you know you have those skills. Create a set of 3 images. You can use hooks and qu...

    Weekly Product Data Scraping

    ...URLs. Some of the pages load content dynamically, so the solution may need a head-less browser approach (Selenium, Playwright, or similar) in addition to classic libraries such as Scrapy or BeautifulSoup. The workflow I picture is straightforward: the crawler launches on a weekly schedule, pulls the latest product information, cleans and deduplicates the results, then exports everything to either CSV and/or JSON. A quick push to a Google Sheet or an S3 bucket afterward would be ideal so the file is immediately usable by the rest of my team. Deliverables • Well-commented source code (Python preferred) • A simple scheduler set to run weekly (cron, Windows Task Scheduler, or self-contained) • Sample output file showing at least one successful pull from each ta...

    ...The same bot should analyse each learner’s progress and automatically propose a personalised learning path, surfacing modules to revisit or skip based on quiz scores and activity logs. Dashboards • Student dashboard: clean view of lessons completed, scores, chatbot interactions and career-readiness checklist. • Instructor / admin dashboard: aggregate analytics, cohort comparisons, exportable CSV reports and a simple CMS to upload or edit lesson content.

    ...birth, ID numbers, etc.) has to be filled. Basic validation—presence checks and simple format rules—is sufficient; anything more can stay out of scope for now. • The end result should feel native: once the API call succeeds, the user sees the customer screen with every mapped field in place and can immediately continue the usual onboarding process. Deliverables I expect: 1. Integration code (Java / PL-SQL wrapper or preferred Flexcube extension) committed to a Git repository. 2. Mapping document that shows each JSON field and its corresponding Flexcube column. 3. Simple test script or Postman collection proving the end-to-end flow. 4. Brief deployment notes so our ops team can move it from UAT to production without a hitch. If you’ve worked wi...

    ...spreadsheets filled with plain text records that now need to live in clean, well-structured CSV files. Your task is to pull every row from those sheets, check that the headings stay consistent, and export the results as UTF-8 CSV without introducing any hidden characters or broken line breaks. The spreadsheets are already organised, so no deep data cleansing is required—just tidy up obvious spacing issues, preserve punctuation, and make sure every cell ends up in the correct column position in the final CSV. I will share the sheets in either Google Sheets or Excel; work in whichever environment you prefer as long as the finished deliverable is a set of ready-to-import CSV files. Deliverables • One CSV per source sheet, correctly ...
