Modular architecture
Turned unstable, tightly coupled product code into explicit packages and system boundaries that teams can develop independently.
I build systems
that hold up.
Senior full-stack engineer working across mobile, backend, infrastructure, and the engineering practices that connect them.

Application — Domain-focused services and predictable workflows
Selected impact
01 / 05Offline-first systems
Built mobile workflows, maps, and versioned local data that keep working when connectivity is unreliable.
Engineering foundations
Established testing, delivery automation, infrastructure, and mentorship practices that make good engineering repeatable.
Experience
From mobile architecture to infrastructure, I work across the boundaries where systems usually break.

Senior Software Engineer
Platform architecture
Architected a Flutter monorepo for a consumer mobile app and an internal insurance portal. A modular Melos package structure gave a six-person team clear, independent feature boundaries.
Reliability by design
Stabilised a crash-prone codebase with Clean Architecture, explicit data/domain/presentation boundaries, and a comprehensive testing strategy that made failures predictable and diagnosable.
Offline-first systems
Designed resilient field workflows using Bloc and hydrated persistence so core pet-health insurance operations remain useful through network disruption.
Backend and delivery
Built FastAPI services and database schemas, delivered a Next.js and NestJS Quote and Buy rewrite, and established Terraform, GCP, CI/CD, release automation, and PR quality gates.
Engineering foundations
Mentored engineers in software design, DDD, events, interrupts, networking, and systems thinking—building capability beyond framework-level knowledge.
Selected work
A cross-section of systems, language tooling, mobile architecture, and developer infrastructure.
Systems &
language projects
The lower layers are where I go to understand the whole system.

AOS / SOS — seL4 Operating System
A POSIX-compatible operating system built on the seL4 microkernel.
View sourceDesigned core operating-system subsystems around an event-driven runtime, including process creation and ELF loading, virtual memory with demand paging and swap, a virtual file system, timers, IPC, and asynchronous I/O.
Subsystem mapFocus a component to follow the pipeline.
Expertise
Broad enough to ship the whole system.
Deep enough to improve its foundations.
