PWA Pre-Launch Technical Audit

My progressive web application is code-complete and sitting on a staging server. Before I push the button on a public launch, I need a senior full-stack developer to give it a final, professional once-over.

Scope of the audit
You will comb through the entire stack—frontend, service-worker layer, API gateway, and database schema—to highlight flaws, risks, and quick wins. Code style is less important than robustness, scalability, and future maintainability. Security is paramount: authentication and permissions, APIs and data handling, plus database security all need a deep dive. On performance I am especially interested in real-world load time, responsiveness, server efficiency, and overall resource usage. I also want your take on horizontal scaling options and any architectural refactors worth considering pre-launch.

Deliverables (all required)
• A written audit report (PDF or MD)
• Issue & risk log with severity ratings
• Actionable recommendations ordered by priority and effort
• A clear “go / no-go” launch verdict with rationale

What will help you succeed
You have a track record auditing PWAs, comfortable reading TypeScript/React code, Node-based micro-services, and SQL + NoSQL data stores. Familiarity with automated security scanners, Lighthouse, WebPageTest, and profiling tools is a plus; feel free to suggest alternatives you prefer.

Please include links or brief summaries of at least two comparable audits you have delivered, your estimated turnaround time, and your proposed cost structure (hourly or fixed, plus any milestones). I’m ready to start as soon as I find the right partner, and quick, clear communication will move you to the front of the line.
