Code Maintenance and Optimization
Slow Code? Optimization Speeding It Up Exponentially
Code Maintenance and Optimization
Healthy, fast and secure code: refactor, up to date dependencies, testing and CI/CD with clear metrics.
Volver a Programming
Overview
We maintain and optimize codebases for reliability, performance and security. We execute metrics driven refactors, keep dependencies up to date, speed up load times and raise quality with tests and CI/CD. You get full visibility and less technical debt.
Scope: Laravel, Vue.js, PHP, JavaScript, Composer and NPM, database migrations, queues and jobs, front assets, API and controllers, repos and branches, CI/CD pipelines, secrets and environment config.
Metrics: test coverage, cyclomatic complexity, module hotspots, bundle size, p95 latency, queries per request, cache use, green build ratio, cycle time and defects per deploy. Dashboards show trend and impact.
Alerts for package vulnerabilities, licenses, deprecations, build failures, slow flows, error endpoints and performance regressions. Ticket integration and priority by impact.
Continuous improvement
Audit
Map modules, technical debt and risks. Quick wins and iterative plan.
Refactor
Patterns and simplification with tests, no visible behavior change.
Measure
Validate impact on performance, errors and delivery time with KPIs.
Every change is tracked end to end: analysis, decision, PR, tests, deploy and result.
Automation
Less risk, reliable releases and shorter cycles.
Key capabilities
Modularization, removal of duplication, right patterns, tests and peer review to keep intent and compatibility.
Version policy, lock and regression tests. Fixing vulnerabilities and licenses in Composer and NPM.
Query tuning, cache, queues and bundle size. Lazy load and memoization where it brings value.
Config hardening, SAST and DAST, secret management, injection and XSS mitigation, permission review.
Unit, integration and end to end, realistic fixtures, critical paths coverage and smoke tests on deploy.
Pipelines with validations, reproducible artifacts, semantic versioning and safe release strategies.
Service logs and metrics, endpoint traces and error budgets. Alerts for regressions and saturation.
Architecture guides, ADRs, patterns, API contracts and team contribution checklist.
Operational KPIs
| Metric | Target | Current | Comment |
|---|---|---|---|
| Test coverage | >= 80% | 86% | Critical paths covered |
| Time to merge | <= 24 h | 10 h | Small PRs and fast reviews |
| Defect rate | <= 0.2% | 0.09% | Regression controlled by tests |
| Green builds | >= 95% | 98% | Stable and fast pipeline |
| Bundle size | <= 300 KB | 240 KB | Split and cache effective |
Summary
Healthy and fast code lowers risk and cost. With metrics guided refactor, safe dependencies, testing and CI/CD, we achieve fewer incidents, stable builds and shorter delivery times, with end to end transparency for business and teams.
