...three core sections—Home, About Us, and a Blog area—yet each has to feel cohesive under the same visual language. Here’s what I need from you: • A responsive design that looks polished on desktop and mobile • A Home page that immediately showcases featured projects or imagery • An About Us page laid out for a short narrative, headshot, and contact prompt • A Blog template that matches the rest of the site’s style so I can post updates easily Please build with modern best practices (HTML5, CSS3, lightweight JS or a familiar CMS theme—whichever you’re fastest with) while strictly applying my supplied colors and logo. Once finished, I’ll look for working page files or a fully-installed theme that I can start up...
...infrastructure. I’m considering the CodeCanyon script “WhatsCRM – Chatbot, Flow Builder, API Access” ( ) and I’m equally open to a solid open-source alternative that delivers the same depth of control. What I need is straightforward: install the chosen platform on my server, connect it to the official WhatsApp Cloud API, migrate my current contacts and opt-ins from Interakt, and make sure the flow builder, chatbot module, and public API endpoints all work flawlessly. The end product should let me create broadcast or automated flows without touching the code each time, pull message analytics through the API, and scale to multiple numbers if I decide to add them later. Deliverables • Clean deployment
My site has nine content pages, each showing a two-volume data table. I need those tables to fit comfortably on single pages without forcing users to scroll sideways or hunt for split columns. ...remain neutral. In short: • Resize and embed all three videos cleanly on one page. • Reformat each two-volume table so the full content sits on a single page without side scroll. • Add a flat CTA button to the homepage that routes to the study-guide section. • Build week-by-week navigation so the active week highlights automatically, defaulting to week 1. Use straightforward HTML, CSS, and JavaScript (or a light framework if you prefer) so the solution stays easy for me to maintain. Once done, hand over the updated pages and any support files so I can drop them s...
...share Postman collections, Swagger docs and a private repo as soon as we start; your branch should include clear commits, reusable React (or comparable) components, TypeScript where practical, SCSS or Tailwind for styling and unit tests for critical logic. Completion means: 1. The app runs locally with one command, builds cleanly for production and deploys error-free to our test server. 2. All API calls conform to ONDC schemas; validation errors surface gracefully in the UI. 3. Chatbot replies and recommendation cards pull from the AI service keys I supply and degrade gracefully if the service is unavailable. 4. Lighthouse mobile score ≥ 90 and no console warnings. If you have shipped ONDC-compliant buyers before and can work within the stated cost and timeline, let...

...need someone who understands WordPress, WooCommerce, and the way shipping modules hook into templates to trace why the component is no longer rendering and bring it back on all three pages. The code was working previously; no major changes were made right before it disappeared, so the root cause could be a silent plugin conflict, a template override, an outdated snippet in , or a JavaScript error that stops the calculator from loading.

Please diagnose the issue, restore the calculator’s display on: • product pages • the cart page • the checkout page and confirm that its totals pull the right values from my existing shipping rules.

I have a finished “magic patterns” layout ready in design files and I now need it brought to life on the web. I’m open to either a clean, lightweight HTML / CSS / JavaScript build or a full WordPress theme—whichever you feel will serve the project best—so please share your recommendation when you respond.

Nothing over-the-top, but the motion should feel smooth and professional on desktop and mobile alike. I’ll only refresh the content from time to time, so if you lean toward WordPress, a simple Gutenberg-friendly setup (or a lightweight page-builder you trust) is all that’s needed for occasional edits.
