Architectural case studies

The reasoning
behind the system.

Explore a system through the problem it addresses, its architecture, and the decisions that shape its behavior. Each study connects the design to my engineering contribution.

Featured case studies

Look inside the engineering.

Customer workflows, distributed automation, and device trust—explored through their boundaries, lifecycles, and engineering decisions.

Business workflows · Modular SaaS

Every enquiry needs
an owner and a next step.

When leads live in chats and spreadsheets, it is difficult to see who should respond—or which customer is still waiting.

An architecture for connecting enquiry capture, lead assignment, follow-up tasks, and pipeline visibility, with messaging providers behind replaceable integration boundaries.

Designed enquiry workflow

  1. Capture the enquiryContact, source & context
  2. Assign the next actionOwner, task & follow-up
  3. Review the pipelinePending work & customer history
Tenant workspace · Roles · Activity history
A focused workflow for small and medium-sized businesses, with pilot validation planned.

Distributed systems · Workflow orchestration

From scheduled job
to isolated execution.

What happens between scheduling a job and knowing that it finished—especially when a message arrives twice or a service restarts?

A case study in coordinating domain services, tracking run and execution lifecycles, and carrying tenant context into Kubernetes workloads.

Follow the execution

  1. Define & scheduleJob and timing rules
  2. CoordinateRun, execution & Kafka events
  3. ExecuteIsolated Kubernetes workload
Status events → run history & notifications
Tenant context and correlation connect the request to its execution history.

Device IAM · Multi-tenant architecture

A trust lifecycle for connected devices.

How should a device prove its identity, gain access, and change owners without carrying old permissions with it?

A case study in separating device identity, credentials, ownership, and policy—then connecting them through a shared trust control plane.
