Outcomes

The work is scoped around practical improvements that can be shipped, verified, and explained.

A short, actionable audit report that engineering can turn into tickets.

Reduced risk from exposed secrets, unsafe rendering, weak form controls, and routing mistakes.

Improved credibility through tested metadata, accessibility, and visible trust pages.

Deliverables

The engagement produces artifacts your team can use after the work is complete.

Client-side code and route review
Dependency and build configuration review
Form abuse and bot-control review
SEO and structured data sanity check
Risk-ranked remediation plan

Process

A small number of focused stages keeps the work understandable and measurable.

01

Review

Read the codebase, deployment configuration, and live behavior with attention to user-controlled data.

02

Test

Run the existing checks and add focused assertions where a failure would be costly.

03

Report

Document the fixes in priority order, including exact files, URLs, and verification steps.

Audit evidence package

The audit is written for engineering action: each issue includes impact, location, and verification steps.

Scope

Frontend routes, forms, client storage, dependency risk, metadata, and deployment configuration.

  • Secret and token exposure review
  • Unsafe rendering and user-controlled data review
  • Routing, SEO, and trust-page review

Standards

Findings are mapped to widely understood frontend and web application risk categories.

  • OWASP Top 10 and ASVS-relevant controls
  • React and TypeScript safety patterns
  • Accessibility and browser security expectations

Sample report

The output is concise enough to execute but detailed enough to verify.

  • Finding title, severity, and affected file or URL
  • Reproduction and remediation steps
  • Suggested regression test or CI gate

Service level

Audit timing is scoped around the risk of the release being reviewed.

  • Initial risk readout after review completion
  • Critical issue escalation before final report
  • Retest support for remediated high-impact findings

Evidence

The strongest trust signals are specific, verifiable, and close to the implementation.

  • TypeScript no-emit checks
  • Vitest route and utility tests
  • Browser verification for key pages
