Services Β· Singapore

Everything you need to build, ship, and scale software.

From a one-week prototype to a multi-year platform engagement, Codegiz covers the full software lifecycle β€” design, engineering, AI, cloud, data, security, and ongoing operations.

Migration & Modernisation
Our core specialism. We help Singapore companies modernise long-running Java, .NET and PHP codebases β€” AI-assisted development lets us move through unfamiliar legacy faster than traditional shops, without the big-bang risk.
Java modernisation (J2EE / Struts / JSF β†’ Spring Boot)

Monolith to microservices (Spring Cloud, GraalVM native)
.NET Framework β†’ .NET 8 rewrites
PHP legacy (CodeIgniter, Laravel 5/6) uplift
Frontend framework upgrades (Angular.js β†’ Angular/React, jQuery β†’ React)
