Web, Backend & Architecture
Mobile apps are the visible edge; the systems underneath are where reliability, security, and scale are earned. Below is how I approach web delivery, API design, and production infrastructure.
Production web
naelnguyen.dev
This portfolio is a production ASP.NET Core site—not a static placeholder. It ships localized Razor views, structured metadata for SEO, strict Content-Security-Policy, and analytics hooks without sacrificing load time.
- UI architecture borrows from Astro-style content islands and Angular-style composition: lean critical CSS, deferred non-essential scripts, and responsive layouts tested across breakpoints.
- Performance is a feature: lazy-loaded media, cache-friendly static delivery, and minimal client-side surface area so first paint stays fast on real networks.
- Clean separation between controllers, views, shared layout, and resource bundles keeps the codebase maintainable as content and locales grow.
Case study
Restaurant operations platform — APIs & data tier
Case study focus: the server side behind reservation, ordering, and kitchen-coordination flows. Work emphasizes versioned REST contracts, transactional correctness, and operational clarity—not a glossy marketing UI.
Stack spans ASP.NET Core on .NET, PostgreSQL for primary OLTP, and MSSQL where legacy reporting and integrations still require T-SQL. Services run containerized for reproducible builds; Nginx terminates TLS and routes traffic with predictable timeouts and gzip/brotli where appropriate. Design goals include idempotent writes where feasible, structured logging, migration-safe schema changes, and least-privilege database roles.

Ongoing work includes Angular feature slices, .NET worker services and minimal APIs, and OpenAPI-first contracts before UI lands. Experiments and reference implementations are published on GitHub—use them as a signal of how I structure modules, tests, and CI-friendly builds.
