My Projects
continous learning

I'm deliberately learning AI engineering at the pace of someone who builds things, not just reads about them. Every topic I study gets turned into something — a mini project, a demo, a published finding. Follow the journey as it happens.

Spring Boot Library
Maven Central MIT
v1.0.0
dev.mpofusindie / iam-spring-boot-starter

A Spring Boot autoconfiguration starter for IAM — drop into any Spring Boot 3 app and Identity & Access Management comes pre-wired. Built with Kotlin, bundling iam-core and iam-api with Spring Data JPA.

React Library
npm MIT
@mpofusindie / iam-react

The React companion to the IAM library — TypeScript-first hooks and components for role-based access control in React apps. Keeps UI permission logic clean and declarative.

Kotlin / JVM Library
Maven Central Apache 2.0
ihawu-core

The framework-agnostic core — a fail-closed masking engine that hides or redacts restricted fields at the serialization boundary, driven by a pluggable policy resolver. No framework required.

ihawu-spring-boot-starter

The Spring Boot adapter — drop it on the classpath and masking auto-configures into your Jackson ObjectMapper. Field policies come from configuration or a bean, with a Spring Security principal bridge and request-scoped caching.
