Hi, friends! Welcome to Installer No. 138, your guide to the best and Verge-iest stuff in the world. (If you're new here, welcome, happy August, and also you can read all the old editions at the Installer homepage.) This week, I've been reading about microwave sounds and Meta glasses and Alex vs. Alix, testing the […]
Solution architect, 17 years in. From March 2026 to July 2026 I was the only hands-on developer on the identity and single-sign-on layer for a Gulf country's national port community system — the platform that fronts its ports and logistics sector. It's live in production. I want to be precise about "sole," because it matters: other people committed to both repos — CI, automation tests, a few fixes, downstream integration work. I authored ~80% of backend commits and ~70% of frontend. Nobody else did hands-on feature development on the core system. That's the honest version. **Volume, straight from `git log --numstat`:** * 602 commits, ~184,000 lines changed across 1,423 files * Backend: 383 Java files / ~21k LOC, 19 controllers, 83 REST endpoints * Frontend: 152 TS/HTML files / ~15.3k LOC, 62 Angular components * 6 external integrations, each with a real *and* a mock adapter * 4 environments, 2 independent penetration tests remediated My own written estimate to leadership in April, before any of this was contentious: 3–4 engineers over 3 months. ## Architecture Hexagonal (ports and adapters) + CQRS. The domain package has **zero Spring or JPA imports** — greppable, returns nothing. That's the actual test of whether hexagonal is a design decision or a buzzword, and most codebases claiming it fail that check. domain/ Pure domain — models, value objects, events, ports. No framework imports. application/ Use cases — Commands (writes) and Queries (reads), DTOs, assemblers. dataprovider/ Adapters — JPA entities, Spring Data repos, SOAP clients. web/ Inbound adapter — controllers, DTOs, mappers, JWT filter, SAML handler. Every feature is a paired `XxxCommand`/`XxxCommandImpl` (transactional writes) and `XxxQuery`/`XxxQueryImpl` (read-only). Every external dependency sits behind a port with a real and a mock adapter selected by Spring profile — which meant QA and UAT ran full end-to-end flows without depending on government systems being up. They frequently weren't. One JPA
I drafted this post years ago but didn’t finish it until now. The concept I write about has shaped the way I design software more than anything else, and I believe every software engineer should be introduced to it early in their career. P.S. I don’t want the title to come across as clickbait: the post is about ADT. submitted by /u/alex35mil [link] [留言]
