A Backend engineering
The services themselves: contracts, business logic and the security around them.

02 / Engineering universe
One core.
Five layers around it.
Java and Spring Boot sit at the centre. Everything else exists to design, ship and keep those services healthy. Tap a layer.
Core
Java
Spring Boot Microservices · REST APIs
Spring Boot Microservices · REST APIs
B Event-driven architecture & data
How services talk asynchronously and how state is stored, queried and integrated.
C Containers & cloud infrastructure
Packaging services and running them on managed compute and Kubernetes.
D Delivery & automation
Getting a change from commit to running service repeatably and safely.
E Observability & quality
Knowing what a service is doing in production, and keeping the code honest.
03 / Code to production
Seven layers.
One trace.
A request crosses every layer below. So does a bug. An illustrative map of the lifecycle I work across, not a diagram of any one system.
- 01
API design
REST contracts, versioning and gateway-level management.
- 02
Application services
Business logic, security and service-to-service calls.
- 03
Event streaming
Decoupling producers and consumers with durable events.
- 04
Persistence
Relational storage, mapping and transactions.
- 05
Containers
Reproducible images, orchestrated and scaled.
- 06
Cloud infrastructure
Compute and managed Kubernetes to run it all.
- 07
Observability
Metrics, traces and logs that show what really happened.
Something is wrong in production. Start at the bottom, follow the signal upward: an alert, then logs and metrics, then the container, the event, the data, and finally the contract.
04 / What I build
Ten things
I do well.
- 01Design and develop Java backend services.
- 02Build and integrate REST APIs.
- 03Work with distributed, event-driven systems.
- 04Implement authentication and authorization.
- 05Integrate relational databases and persistence layers.
- 06Containerize services and work with Kubernetes.
- 07Use AWS compute, Kubernetes infrastructure and monitoring.
- 08Support CI/CD and deployment workflows.
- 09Investigate behaviour with logs and observability tools.
- 10Write automated unit tests and improve code quality.
Public work
- TheBlueprintVoyager Entries on Java design patterns, Spring Boot internals, microservice patterns, Kafka and system-design case studies, written for five-minutes-at-a-time reading.
- Open-Meteo Spring Boot sample that resolves a place to coordinates, fetches current weather, enriches it and stores it in H2.
- Real-time Notification Platform Java 21 and Spring Boot platform with a transactional outbox, Kafka, WebSocket delivery, retries and dead-lettering.
- AutoRemediate AI Agent that finds code-quality and security findings, proposes minimal fixes, verifies them and produces an auditable report.
- Production Bug Minimal Reproduction Finder Dependency-aware delta debugging across Kafka-backed Spring Boot services to find the smallest input that reproduces a bug.
