I’m Tony Dong — a technology leader and hands-on architect who turns ambitious ideas into secure, scalable products. I work across AI, cloud, engineering and product to move businesses from direction to delivery.
I design AI-native engineering systems, not isolated prompts: tool-using agents, context architecture, multi-stage workflows, human checkpoints, testing and operational controls that carry work from requirement to production.
Fractional CTO leadership, technology strategy, architecture governance, product direction, engineering management, recruitment and senior stakeholder alignment.
Resilient SaaS and distributed platforms across Azure, AWS and GCP, using microservices, event-driven systems, containers, serverless and infrastructure-as-code.
Secure NHS-facing systems, AI-assisted clinical document processing and healthcare integration, supported by pragmatic controls for GDPR, ISO 27001, Cyber Essentials, identity, encryption, network isolation and auditability.
Practical depth across TypeScript, Node.js, React, Next.js, React Native, Python, .NET, PHP, PostgreSQL and MySQL, with CI/CD and automated testing.
Start with the business goal, existing systems and delivery context. Separate the important technical problem from the merely interesting one.
Join product, architecture, security, data and operations into one coherent model, with clear trade-offs and a route that teams can actually execute.
Build capable teams, useful standards and AI-native workflows that improve speed and quality without losing human judgment, ownership or control.
I work with businesses that need pragmatic CTO-level leadership across AI, software architecture, cloud platforms, engineering teams and technical strategy.
