About

I build end-to-end products—from polished Angular/.NET web apps to native iOS experiences with SwiftUI. Four years of shipping taught me to care about architecture, UX, and the details users actually feel.

My sweet spot is turning ideas into reliable software: clean APIs, thoughtful interfaces, and performance that holds up under real traffic. I work across the stack so frontend, backend, and mobile stay aligned.

Whether you need a production website, an App Store app, or a backend that scales, I focus on clear communication, solid engineering, and results you can demo with confidence.

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.

  1. 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.
  2. 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.
  3. 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.

Current explorations & repositories

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.
