Legacy System Migration

We audit, plan, and execute migrations from outdated stacks — COBOL, EJB, Struts, or older Spring — to modern Java 21 and Spring Boot 3, minimising downtime and risk.

🧩

Microservices Architecture

We decompose bloated monoliths into independently deployable, scalable microservices — with domain-driven boundaries, API gateways, and event-driven messaging built in.

Web Hosting & DevOps

Managed hosting on AWS or Azure with zero-downtime deployments, auto-scaling, SSL, CDN, and 24/7 monitoring. We set up your CI/CD pipeline and hand you the keys.

// Our Process

From legacy to launch
in four steps.

01
Discovery & Audit
We map your existing architecture, flag risks, and produce a migration blueprint with timeline and cost estimate.
02
Architecture Design
Target state design: service boundaries, data models, API contracts, and infrastructure as code — reviewed and signed off by you.
03
Iterative Migration
Strangler-fig pattern or big-bang where appropriate, with full regression suites keeping your business running throughout.
04
Handover & Support
Documentation, team training, and optional ongoing support retainers so your engineers are confident owners of the new system.

// About Me

Senior Java architect & migration specialist.

I'm a Java and cloud architecture consultant with over 12 years of hands-on experience rescuing and modernising enterprise systems. I've led migrations for financial institutions, logistics firms, and SaaS companies across Australia and internationally.

My philosophy is simple: technology migrations should be low-risk, incremental, and grounded in your business outcomes — not just technical elegance for its own sake.
