Experience

Temporal.io Extension for Quarkus Framework

https://github.com/mostafacs/quarkus-temporal-extension
The Quarkus Temporal Extension project provides a seamless way to integrate Temporal.io workflows into Quarkus applications. Temporal.io enables developers to manage long-running, stateful workflows with retries, timeouts, and fault tolerance features.

This extension simplifies Temporal integration by offering a Quarkus Native setup, reducing boilerplate code, and enhancing developer productivity. Key features include automatic configuration, annotation-based workflow registration, and runtime optimizations to leverage Quarkus's fast boot times and efficient resource management.

This project bridges the gap between modern microservices and advanced workflow orchestration, empowering developers to build resilient applications effortlessly.

eCommerce Microservices

https://github.com/mostafacs/ecommerce-microservices-spring-reactive-webflux
This project demonstrates an eCommerce platform built using a microservices architecture pattern with Spring Boot, Spring Cloud, and Spring WebFlux. The application leverages reactive programming to handle high loads and ensure scalability. It uses PostgreSQL as the database and Docker for containerization.

The architecture includes services such as user authentication, product management, and order processing, all secured with OAuth2 tokens. The goal is to showcase how microservices can be efficiently implemented and orchestrated to create a robust and responsive eCommerce system.

Social Media

https://github.com/mostafacs/social-media-quarkus-microservices-kubernetes
This project showcases a social media platform built using Quarkus, Kafka, and Hazelcast, deployed on Kubernetes. The architecture is designed for high performance and scalability, utilizing Java and JPA for back-end services. Key features include user authentication and authorization via Keycloak, real-time feed processing with Kafka, and caching with Hazelcast.

The project aims to demonstrate best practices in software development, ensuring security and resilience.
