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.
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.
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.
Lighthouse audit, React DevTools profiling, network request analysis, memory leak identification and N+1 query detection.
Issue ranking by business impact (crash > performance > UX > aesthetics). Correction roadmap in 2 sprints.
Bug fixing, slow component optimization, lazy loading, code splitting, caching, optimized SQL queries.
Addition of unit, integration and E2E tests for each fix. Documentation of patterns to avoid for your team.
Our interventions improve performance scores by 40 points on average on the sites we optimize.
Each fix is covered by automated tests. Fixed bugs don't come back at the next release.
We document root causes and patterns to avoid. Your team knows why and how to prevent the same mistakes.
