Technical Architect · Brooklyn, NY · Green Card
Small parts that compose into anything.
Twenty-six years designing platforms where the primitives do the work. I build the metadata layers, languages and composition engines that let product teams ship without writing platform code — and the internationalization underneath that makes it correct everywhere it lands. Founding architect on two 0→1 platforms; teams led across the UK, US and India.

What I do
Five things I've done repeatedly, at enterprise scale, and would do again.
Core discipline
Metadata platforms & domain-specific languages
Designing the notation a platform is configured in, and the compiler and resolution rules behind it: unifying divergent type systems under one DSL, layering algorithms that merge defaults, localizations and per-client customization deterministically, and extensibility models that keep customized deployments upgradeable rather than forked.
- DSL design
- Compilers
- Type systems
- Multi-tenancy
- Extensibility
Specialism
Internationalization & localization at scale
The part most teams discover too late. Culturally-aware formatting across hundreds of regions, translatable metadata and code resources, translation pipelines product teams can run themselves, and the workshops and reference material that get a whole engineering org using them correctly instead of hard-coding assumptions.
- i18n
- l10n
- Unicode
- Translation tooling
- Enablement
Foundations
Distributed systems & cloud
Service decomposition, caching and search performance, event-driven and serverless designs, containerized delivery and the CI/CD to support it.
- Node.js
- AWS
- Docker
- Kubernetes
Leadership
Growing teams and architects
Leading distributed teams across three countries, setting architectural direction and roadmap, running enablement workshops, and mentoring engineers into ownership.

Track record
0 → 1, in regulated domains
Founding architect twice over, including a statutory payroll product filing directly with HMRC. Comfortable where correctness is legally non-negotiable.

Code I've published, and write-ups of problems I've solved.
Case study
[ Title — the metadata layering problem ]
A write-up of the pattern, not the product: how a platform resolves defaults, tenant overrides and locale variants into one deterministic result, and what breaks when the merge order isn't total.

Case study
[ Title — designing for 283 locales ]
What "culturally aware" actually costs, the assumptions engineers encode without noticing, and how to build a formatting layer teams can't misuse.
