Debugging & Performance Optimization

Your application stabilized, optimized and thoroughly tested

A slow or buggy application costs customers. 53% of users abandon a mobile site that takes more than 3 seconds to load. Recurring bugs destroy trust. And accumulated technical debt slows every new feature. Wikolabs intervenes as a high-level firefighting team: we diagnose, fix and thoroughly test, then deliver a stabilized codebase with non-regression tests.

The problem
Without our solution

Hard-to-reproduce bugs mobilize teams for days. Memory leaks gradually degrade production performance. Red Core Web Vitals penalize SEO. And without automated tests, every deployment is a risk.

Our answer
With our AI agent

We conduct a complete technical audit (frontend profiling with Lighthouse + React DevTools, backend profiling with py-spy or APM, memory leak analysis). Each issue is documented, prioritized and fixed. Automated tests (Playwright, Vitest, pytest) are added for each fix to guarantee non-regression.

Deployed in 4 steps

01
Complete audit & profiling

Lighthouse audit, React DevTools profiling, network request analysis, memory leak identification and N+1 query detection.

02
Fix prioritization

Issue ranking by business impact (crash > performance > UX > aesthetics). Correction roadmap in 2 sprints.

03
Targeted fixes & refactoring

Bug fixing, slow component optimization, lazy loading, code splitting, caching, optimized SQL queries.

04
Automated tests & documentation

Addition of unit, integration and E2E tests for each fix. Documentation of patterns to avoid for your team.

Measurable results

01
+40 Lighthouse points on average

Our interventions improve performance scores by 40 points on average on the sites we optimize.

02
Zero post-fix regressions

Each fix is covered by automated tests. Fixed bugs don't come back at the next release.

03
Upskilled internal team

We document root causes and patterns to avoid. Your team knows why and how to prevent the same mistakes.
