About the project

We are seeking a Full Stack Developer to support the migration of a critical web application from Windows servers to a target application server hosted on Red Hat Linux, and subsequently provide development and maintenance for both the web layer and Oracle backend components post-migration. This role includes system integration, UAT/OAT support, defect resolution, production readiness, and ongoing enhancements in PL/SQL and scripting for data handling and automation.

This two-phase role is crucial for ensuring smooth migration completion in 2026 and delivering high-quality application development afterward.
