Project details
Do you have a website, SaaS platform, dashboard, CRM, marketplace, or web application that needs a technical review before further development?
I will audit your existing product as a full stack developer and provide a clear overview of the main issues that may affect performance, UI/UX, code quality, scalability, security basics, and future improvements.
This service is useful if you already have a live website, prototype, partially built platform, or saas mvp and want an independent technical opinion before investing more budget into fixes, redesign, refactoring, or new features.
What I will review:
Frontend structure and visible UI/UX issues
Code structure and maintainability
Backend/API logic, if access is provided
Basic security concerns
Integration or third-party service risks
Technical blockers for future web development
Architecture audit
What you will receive:
A focused audit report with key findings
Priority list of issues to fix first
Practical recommendations from a website developer perspective
Notes on possible risks and blockers
Suggested next steps for future development

Full Stack Developer React Node (Full-Stack Node.js, SaaS)
Gregory was a pleasure to work with on our Full-Stack Node.js + React/Next.js application. As a full stack developer react node, he took ownership of several feature slices end-to-end - from refining requirements and updating our data models to implementing clean UI in React and robust API logic in Node.js. His PRs were well-structured, covered by tests, and easy to review thanks to clear descriptions and comments. Gregory also collaborated smoothly with the rest of the team, proactively suggesting improvements to performance and error handling. I highly recommend him for any production full stack node.js react projects.
