WHAT YOU'LL
ACHIEVE

Real-world skills that translate directly to career growth and production impact

Architect Event-Driven Systems with Quarkus & Kafka

Go beyond simple REST APIs. Design and build a resilient, scalable microservices architecture using the event-driven patterns that power modern tech companies. Master reactive data streams with Quarkus and Apache Kafka.

Event-Driven ArchitectureQuarkusKafka

Build High-Performance, Cloud-Ready Microservices

Learn why Quarkus is built for the cloud. Compile your Java code into a blazing-fast native executable using GraalVM. Create lightweight, containerized services that start instantly and scale efficiently in Kubernetes, slashing cloud costs.

High-PerformanceGraalVMKubernetes

Accelerate Development with the Full Quarkus Ecosystem

Stop wrestling with boilerplate code. Leverage the full power of the Quarkus ecosystem to build faster. Use Hibernate Reactive Panache for simplified data access, RESTEasy Reactive for modern APIs, and other key extensions to become a highly productive developer.

Developer ProductivityQuarkus EcosystemFull-Stack

Secure and Monitor Applications for Production

A running app isn't a production-ready app. Implement ironclad security with OIDC and JWT. Set up a complete observability stack with Prometheus, Grafana, and OpenTelemetry to monitor, trace, and debug your system with confidence like a true Site Reliability Engineer (SRE).

WHAT YOU'LL
[BUILD]

A real-time indoor tracking platform with Quarkus 3 (Java 25, Native) using Kafka, MongoDB and reactive microservices. You'll implement an end-to-end system: data ingest, event processing with in-memory caching, SSE/WebSocket streaming, a Nuxt4 + OpenLayers web app, Keycloak authentication, and full observability (Prometheus, Grafana, Jaeger). By the end, you deploy optimized native images to microk8s kubernetes cluster and master Quarkus for high-performance, cloud-native IoT workloads.

Simulator Service

Learn Quarkus REST Client Reactive, @Scheduled producers, movement patterns with state machines, backoff strategies with SmallRye Fault Tolerance, and circuit breakers.

REST Client • Schedulers • Config Mapping

Kafka Messaging

@Outgoing/@Incoming channels, serializers, partitioning, compression, DLQ patterns, trace context propagation, and consumer lag monitoring.

Reactive Messaging • Mutiny • DLQ

Stateful Processing

Caffeine cache for pet/zone state, LRU + TTL policies, warm-up from Zone Service, enrichment pipelines (velocity, direction, point-in-polygon)

Caffeine • Cache Metrics • State Machines

MongoDB Time-Series

Reactive Mongo client, time-series collections with timeField/metaField, batch writes with Multi.buffer(), insertMany, TTL indexes, and graceful shutdown flush.

Reactive MongoDB • Batching • TTL

SSE & WebSockets

Server-Sent Events for browsers, WebSocket lifecycle, session registry, backpressure (drop vs buffer), fan-out approaches, and MessagePack binary format.

SSE • WebSockets • Backpressure

Observability & Native

Micrometer counters/timers, OpenTelemetry spans, structured JSON logs, Grafana dashboards, Mandrel 25 native builds, Docker multi-stage, container scanning.
