Baahith Search Platform Enhancement

I recently launched Baahith, a single-click search and knowledge-discovery platform that already aggregates vetted sources in Tech Insights, free international courses, aviation news, and live football streams through Google, Bing, DuckDuckGo, Yahoo, and Brave. Now I am ready for the next iteration and would like help in two key areas:

1. Broaden the knowledge base
• Add the “Healthcare & Medicine” and “Financial Markets & News” categories to the existing smart-aggregation engine.
• Identify, validate, and plug in high-quality, publicly available web sources for each new category so they fit seamlessly into the current sector-based navigation.
• Make sure query routing, filtering, and result presentation remain consistent across all integrated search engines.

2. Refine the user interface
• Rework the navigation to feel more intuitive, keeping the minimalist, high-performance spirit of the site while reducing click depth to key resources.
• Introduce a lightweight theme system that lets users switch between at least two visual styles and adjust basic color accents without slowing the experience.
• Maintain full responsiveness on mobile and tablets and preserve the clean, uncluttered look on desktop.

Deliverables
- Integrated “Healthcare & Medicine” and “Financial Markets & News” sections populated with reliable sources.
- Updated front-end code and assets implementing improved navigation and theme switching.
- Any supporting documentation or configuration notes needed for me to maintain and expand these features.

I will provide full access to the existing repo and a staging environment so development and testing can proceed smoothly. If you have experience wiring multiple APIs, curating niche data sources, and polishing modern UI/UX, I’d love to collaborate on this upgrade.
