About this role
JavaScript, Python, Django, NoSQL Couch & Mongo, PostgreSQL, Docker, Web Development, API, Backend Development, Frontend Development · My React / Django product is functional but sluggish: page-to-page navigation feels heavy and the interface hesitates while assets and data arrive. Front-end responsiveness is my top concern, with loading speed during route changes standing out as the clearest pain-point.
I’d like you to profile the whole stack—React, Django REST, Postgres, Docker containers—and surface the real bottlenecks, then implement fixes that hold up in production. That may involve component-level code-splitting, smarter state management, query optimisation, async views, or container tuning; I’m open to whichever proven techniques your investigation justifies, provided the end result is measurable and clearly documented.
Deliverables • A short report summarising each bottleneck found, the metric before/after, and the remedy applied • Clean, tested commits (unit or integration as appropriate) for both frontend and backend • Updated Docker files or scripts if runtime tweaks are needed • Inline comments plus a concise README section describing how to reproduce the benchmarks and run the new build
Quality is paramount, so please favour readable code, descriptive commits, and reliable tests over q
