My gadget buy-back platform already has a live Android app and website; now I want to push usability a step further by adding advanced search filtering—this is the only new functionality I’m focusing on at the moment. The goal is simple: let visitors slice our catalogue by multiple parameters in one go and surface results instantly. I’m happy to discuss the exact filter set, but price range sliders, brand selection, and condition toggles are the starting point I have in mind. You’ll need to wire a clean, native-feeling UI on Android and a consistent component on the web, then back it with efficient queries and an API endpoint that supports combined parameters without slowing things down. Deliverables • Backend endpoint(s) that accept multiple filter criteria and return paginated results • Updated Android and web search interfaces with dynamic filters • Unit/integration tests proving accuracy of results and stability of existing search • Brief deployment notes and inline code comments for my in-house team Acceptance criteria • Any filter or combination returns correct products in under 300 ms on datasets up to 100 k items • No regressions in current browsing flows • All code merges cleanly into our Git repository and passes existing CI checks Codebase access, sample data, and design assets will be provided as soon as we kick off. If you’ve implemented similar multi-facet search before and can keep performance tight, let’s get started.

Hello, I’m a backend and full-stack developer experienced in building high-performance, multi-facet search systems for mobile and web marketplaces. I’ll design and implement efficient API endpoints that accept combined filter criteria, return paginated results, and meet your performance target of sub-300ms on datasets up to 100k items. My approach emphasizes indexed queries and lightweight caching (e.g., optimized SQL with appropriate indexes or a search engine like Elasticsearch where appropriate), clear API contracts, and non-breaking integration with your existing codebase and CI pipeline. ~Android & Web UI: implement native-feeling filter components and a shared web component that update results instantly. ~Backend: deliver endpoints that accept multiple parameters, return paginated responses, and include query optimizations and optional caching. ~Quality: provide unit and integration tests covering filter combinations, performance checks, and inline comments plus short deployment notes for your in-house team. I will ensure no regressions to current browsing flows and that all changes merge cleanly into your repo. I’ve shipped similar multi-facet search features and can move quickly once I have repo access, sample data, and design assets. I’ll keep communication clear and provide a concise hand-off so your team can maintain and extend the filters easily. Best regards, Abbas Ali.
