Golding Software · Sydney, Australia

Fractional CTO &
Principal Engineer

Senior technical leadership, hands-on engineering, and specialist platform consulting for companies that don't need - or can't yet justify - a full-time hire. I'm Horacio Golding: 25+ years building and leading software teams across airlines, banking, payments, insurance, health, and government.

What I do

Fractional CTO

Technology strategy, architecture, and engineering leadership for startups and scale-ups. Roadmaps, build-vs-buy decisions, hiring and mentoring, vendor management - a CTO's judgement, from a few hours a week instead of a full-time salary.

Principal Engineer

Hands-on architecture and delivery inside your team: APIs and microservices, event-driven systems, modern web front ends, and AI-powered applications. I can own the whole lifecycle or just the piece you need - architecture and design for your developers to build, or delivery of your architect's design - and stay on afterwards for SME support, faster CI/CD, and continuous cost and performance improvements.

API platforms & cloud foundations

Apigee X implementation and Edge-to-X migration, GCP landing zones, Kubernetes, CI/CD pipelines, infrastructure as code, and cloud cost optimisation - well-scoped projects delivered end to end on GCP, AWS, or Azure, and equally at home in hybrid and on-premises environments.

AI-accelerated delivery

I build with Claude Code and agentic workflows every day - one senior engineer delivering at the pace of a small team - and help engineering teams adopt AI-assisted development with the right guardrails.

Engagement titles are flexible - Principal Engineer, Platform Engineer, or simply Consultant, whatever fits your team.

Outcomes, not hours

  • 70% cloud cost reduction - about A$500k a year - on a high-traffic airline pricing system, through performance and infrastructure redesign.
  • Hundreds of thousands a year saved at a national retailer by replacing HashiCorp Vault and Terraform Cloud with Azure-native services (Key Vault, Blob Storage) for secrets and Terraform state.
  • Three Apigee X implementations - two with full GCP landing zones - for a national news organisation, a financial services company, and a national retailer.
  • Deployments cut from one day to minutes at a national insurer, with a new CI/CD pipeline.
  • First commit to multi-market production rollout of a booking-management platform for a major airline.
  • CTO of a telehealth startup - led the engineering department from just after launch through growth.

I don't publish client names or case studies - the work was delivered inside their teams, and that discretion extends to every engagement. Specific references are available on request.

About Horacio

I've been building software since 1999 - starting on mainframes, through heavy Oracle database and client-server development, to web systems, cloud platforms, and now AI-powered applications - and I've worked at every level from developer to senior, lead, principal, and CTO, in startups, large enterprises, and the public sector. I stay hands-on. Engagements run through my company, Golding Software Pty Ltd, either directly or through your preferred agency or consultancy.

I'm also a daily practitioner of AI-assisted development - Claude Code and agentic workflows are part of how I ship, not a slide in a deck - and I help teams adopt the same practices with sensible guardrails.

Master of Computer Science (University of New England) · Google Cloud Certified Professional Cloud Architect · Postgraduate Diploma in General Management (Macquarie University).
