React-Python Trading App Optimization
Publicada el 2026-07-31
Descripción de la oferta
I have an existing trading application with a React/JavaScript front end and a Python back end. Right now every button press lags, buffers, and occasionally stalls the UI, so users lose confidence while placing trades. Both layers need attention: the interface should feel crisp and modern while the underlying Python logic must respond in near-real time. Front end goals • A cleaner, more intuitive UI • Noticeably faster page and component load times • Smoother button interactions with no visible buffering Back end goals • Rework the button-handling algorithms so responses are instant and reliable • Introduce a few small feature hooks that the current code base left unfinished • Squash any bugs you uncover while profiling Key tech in play includes React, functional components, hooks, WebSocket feeds, Python 3.x, async I/O, and a Postgres data store. I will give you the Git repo, a short architectural overview, and sample market data so you can spin up the project locally. Deliverables 1. Updated React code committed to a feature branch, passing existing unit tests and Lighthouse scores that show a performance lift. 2. Refactored Python modules for button actions, benchmarked to sub-150 ms round-trip time on my staging server. 3. A concise changelog plus any new tests that prove the fixes and enhancements work. If you’ve tuned trading or real-time dashboards before and can walk me through your optimization approach, let’s talk—my priority is speed and reliability without a total rewrite.
