Software Engineer

We're looking for a senior full-stack developer to perform a focused engagement on a web platform nearing production launch. This is a short, high-impact contract covering end-to-end testing, code review, production hardening, and deployment finalization.

You'll be reviewing and validating work completed by the existing development team, not building from scratch. The platform is functional and deployed to staging; we need a seasoned set of eyes to pressure-test it before go-live.

Scope of Work

• Testing & QA: Execute end-to-end smoke tests across the platform. Identify edge cases, broken flows, and UI/UX inconsistencies. Validate role-based access control and permissions across user types.
• Code Review: Review frontend and backend codebases for quality, security, and maintainability. Flag anti-patterns, potential vulnerabilities (OWASP Top 10), and performance concerns.
• Production Readiness: Audit deployment configuration, environment variables, CI/CD pipeline, and infrastructure setup. Verify error handling, logging, and monitoring are production-grade.
• Deployment Support: Assist with final production deployment and post-deploy verification.
• Documentation: Deliver concise findings report with prioritized recommendations.
