Be ready to demonstrate real production experience with Classic ASP.NET, particularly how the frontend and middle tier interact with backend services and databases.

2. Oracle PL/SQL

Focus heavily on stored procedures, SQL troubleshooting, data manipulation, performance considerations and diagnosing database-related application failures.

3. Legacy Full-Stack Development

Understand how to work safely within a mature production platform where changes must integrate with existing business logic and legacy components.

4. End-to-End Ownership

Be prepared to explain how you take a requirement through:

Database → Middle Tier → Frontend → Testing → Production

• React
• Node.js
• PostgreSQL
• Kafka
• Claude Code
• Codex
• Other AI-assisted coding tools

AI coding tools are described as a plus rather than a core requirement.

QUALIFICATIONS

• Production Classic ASP.NET experience
• VB.NET experience
• VBScript experience
• Java/JavaScript experience
• Strong Oracle PL/SQL skills
• Stored procedure development and troubleshooting
• Redis or comparable caching experience

POTENTIAL GAPS TO CHECK

Before applying or interviewing, assess your experience in:

• Classic ASP.NET specifically, rather than only modern ASP.NET Core
• VB.NET and VBScript
• Oracle PL/SQL and stored procedures
• Legacy/mature production applications
• Redis or equivalent caching
• Frontend + middle-tier ownership
• Long-term project tenure
• New Jersey onsite availability

A strong modern React/Node.js developer without meaningful Classic ASP.NET, VB.NET and Oracle PL/SQL experience may not align closely with the core technical requirements.
