Slow apps lose users. Performance is a product feature.
Research shows users abandon apps that take more than 3 seconds to load. If your application is slow, users are leaving before seeing the value. Performance problems have specific, fixable causes — and the fixes don't always require a rebuild.
Application that's slow enough that users are noticing and complaining — or churn data showing users leaving after experiencing slow load times
Slow applications have specific causes. The diagnosis determines the fix:
Slow initial page load. Too much JavaScript downloaded before the page renders. Fix: code splitting, lazy loading, tree shaking. Next.js handles most of this automatically, but large third-party libraries (maps, charts, editors) need lazy loading.
Slow data fetching.
N+1 database queries: loading a list of 50 items, then separately querying each item's related data = 51 queries. Fix: JOINs or ORM include statements to batch into one query.
Missing database indexes.
A query filtering on a column without an index runs a full table scan. At 1,000 rows: fast. At 100,000 rows: noticeable. Fix: EXPLAIN ANALYZE to identify missing indexes, add them.
Slow API endpoints. Check your API response times in your monitoring tool. If any endpoint takes > 500ms consistently, investigate that endpoint specifically.
Unoptimized images.
Original 4MB JPEG served to a mobile user. Fix: Next.js <Image /> component handles resizing, WebP conversion, and lazy loading.
No caching. Expensive computations repeated on every request. Fix: Redis cache for the output of slow queries or computed data that changes infrequently.
Waterfall requests.
Sequential API calls where parallel calls would work. Fix: Promise.all() for independent requests.
The measurement step: Before fixing, measure. Chrome DevTools Network tab, Lighthouse audit, and application monitoring (Datadog, Sentry performance) identify where the time is actually being spent.

One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.
Measurably faster application with specific performance improvements: faster initial load, faster data fetching, and improved perceived performance through UI feedback
Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Performance improvements are scoped from the audit. Each identified bottleneck is a discrete fix.
Questions, answered.
Depends on the current state. Applications with obvious unindexed queries and N+1 patterns often see 5-10x query speed improvement. Frontend bundle optimization can cut initial load by 30-50%.
Optimize first. Rebuilds are expensive. Most performance problems can be fixed in the existing application without a rewrite.
