01
Interfaces with a point of view
Native products
Desktop and mobile experiences that feel considered on the platform, not merely contained by it.
02
Complexity made coherent
Systems thinking
Architecture that makes disagreement between data, UI, and operations difficult by design.
03
Automation people can trust
Agentic workflows
AI-assisted systems with explicit contracts, safe boundaries, and outcomes people can verify.
04
Quality carried through release
Launch discipline
Testing, release automation, observability, and documentation treated as product work rather than cleanup.
I build software that solves real operational problems.
I'm Anthony Su, a product engineer working across desktop, mobile, web, and agentic systems. I take products from early requirements through architecture, implementation, testing, and release.
- Define
- Design

Started building software
First applications, late nights, and a curiosity for how systems work.
Shipped products that scale
Delivered features end-to-end and learned the discipline of impact.
Led across areas
Architecture, execution, and collaboration across cross-functional teams.
Focused on operational impact
Building software that streamlines operations and drives real business outcomes.
Work that compounds.
Roles organized around what shipped, what improved, and what each chapter made possible next.
Product Engineer (Full-Stack & Backend)
Co-building a software-protection and licensing platform in a two-person team, owning product engineering across the backend, the developer-facing web app, and release.
- Designed the licence-verification service and hardware-bound activation flow that gate every protected build, including key issuance, revocation, and reset handling.
- Built the binary-protection pipeline that accepts EXE, DLL, APK, IPA, and DMG uploads and returns VMP-style hardened artifacts with one-click delivery.
- Delivered the developer dashboard for uploads, licence management, and activation telemetry, with end-to-end tests guarding each release.
- Established the backend architecture, continuous integration, and deployment workflow that lets a two-engineer team ship weekly.

Grand Resort & Residence
Building the resort's public website and the content and distribution systems behind it, from the first design through day-to-day operations.
- Architected and built the hotel's custom CMS from the ground up, giving staff control over rooms, rates, galleries, offers, and multilingual page content without developer involvement.
- Implemented OTA channel management that keeps availability and rates consistent across the direct booking path and third-party travel platforms.
- Shipped a statically rendered, image-led marketing site with a booking flow that stays fast on hotel-lobby Wi-Fi.
- Set up structured data, sitemaps, and performance budgets so the property ranks for direct searches rather than relying on OTA commissions.

Full-Stack Engineer
Full-stack engineer on DJL, an open-source, local-first desktop AI agent, working in a two-person team from architecture through public macOS and Windows releases.
- Co-built the agent's core workflow — planning, tool execution with every step visible, and human approval gates — for macOS and Windows.
- Implemented multi-model routing so the agent switches between cloud and local models without changing the user's workflow.
- Built the automated release pipeline that packages, validates, and publishes signed macOS and Windows builds from a single workflow.
- Designed and shipped the bilingual English and Chinese launch site in May 2026, covering downloads, capability explanations, and local-AI education.

Owned the full stack of an offline-first supermarket point-of-sale system for Windows and macOS, from the data model to retail hardware integration.
- Built the licence-verification system that activates and audits every installation, backed by encrypted cloud backup so stores keep selling when the connection drops.
- Delivered inventory tracking, a back-office CMS, and receipt generation covering barcode checkout, customer credit, layaway, and eGift cards.
- Integrated every major ESC/POS receipt printer, barcode scanner, and mobile scanning workflow behind one device-agnostic hardware layer.
- Shipped trilingual operation and a single-screen tender flow, validated with store staff before rollout.

Notes from the work.
Practical writing on rendering, architecture, search visibility, and the systems behind dependable product work.
Your Sitemap Will Drift, So Derive It
Hand-maintained sitemaps fall out of sync with the routes they describe. Declaring routes once and generating everything from that list removes the failure.
Why AI Crawlers Cannot See Your Animated Hero
Most AI search crawlers do not execute JavaScript, so text rendered only on the client is invisible to them. Here is how to check and fix it.
