Most founders do not realize that a 5-second page load is quietly costing them sign-ups.
Recently, I audited a client platform that was struggling with heavy architectural bloat. The main dashboard had an LCP of 5.2 seconds, and bounce rates were climbing every week.
Here is what I changed in production:
Replaced the legacy setup and rebuilt the core workflows with Next.js 15 and TypeScript.
Reworked data fetching using React Server Components and proper PostgreSQL indexing, so heavy queries stopped blocking the page.
Fixed layout shifts and optimized asset delivery to reach green Core Web Vitals.
The outcome:
LCP dropped from 5.2 seconds to 850ms.
Server response times were reduced by 68%.
Sign-up drop-off decreased by 31% in the first two weeks after launch.
Clean architecture is not a luxury. It directly protects your runway and your retention.
I am taking on 1 new engineering project this month. If your web app or SaaS feels slow, or tech debt is slowing down your shipping, send me a message here on Contra with your current stack.
