Building a landing page / marketing site with Java? Let us review it.
Expert code review for landing page / marketing sites built with Java. We fix Java-specific security gaps, optimize performance, and handle deployment. From $19.
Common Java issues we find
Real problems from Java codebases we've reviewed.
SQL injection via string concatenation
Building SQL queries with string concatenation instead of PreparedStatement or parameterized JPA queries, allowing attackers to manipulate database operations.
Missing input validation
Controller endpoints accept request bodies without Bean Validation annotations (@Valid, @NotNull, @Size), allowing malformed data into business logic.
Thread safety issues
Mutable shared state accessed from multiple threads without synchronization, volatile, or concurrent collections — causing race conditions in production.
Resource leaks
Database connections, streams, and file handles opened without try-with-resources, leading to connection pool exhaustion and OutOfMemoryErrors.
Landing Page / Marketing Site challenges to solve
Key landing page / marketing site concerns that AI-generated code often misses.
Page speed
Landing pages must load in under 2 seconds. AI tools generate bloated CSS, unoptimized images, and unnecessary JavaScript that slow loading. A 1-second delay in load time reduces conversions by 7%.
SEO fundamentals
Missing meta descriptions, incorrect heading hierarchy, no Open Graph tags, no structured data, and no sitemap. AI tools build the visible content but skip the invisible SEO infrastructure.
Form handling
Your contact form, waitlist signup, or demo request form must work flawlessly. AI-generated forms often lack validation, error messages, success confirmations, and backend integration.
Mobile responsiveness
Over 60% of traffic is mobile. AI-generated layouts sometimes break on small screens — overlapping elements, unreadable text, and inaccessible buttons. Every pixel matters for conversion.
