Optimize App Performance & Security

I have a fully-functioning application that users like, but it has started to feel sluggish and I’m concerned about occasional crashes and potential security gaps. My goal is simple: tighten the code so the app loads faster, runs reliably under heavy traffic, and follows current security best practices. You’ll receive full access to the existing repository and a summary of the pain points I’ve observed. After an initial audit, you’ll recommend the quickest wins and any deeper refactors required; once we agree on the plan you’ll implement, test, and document every change. Deliverables • Performance and security audit report (baseline metrics, discovered issues, action plan) • Optimised code committed to the repo with clear comments • Updated dependency list and configuration files • Automated test suite covering new or affected areas • Final benchmark and security scan showing measurable improvement over the baseline • Brief hand-over document so my in-house team can maintain the improvements Acceptance criteria • App start-up time reduced by a noticeable margin (exact target set after baseline) • No new errors in the crash logs after one week of internal stress testing • External security scan returns zero high-severity findings • All tests pass in our CI pipeline If you have a track record in performance tuning, memory profiling, and secure coding, I’d love to see how you can help push this release over the finish line.
