Hello, I'm

Mattz

Flutter specialist and edge systems engineer.

I build cross-platform mobile apps that never drop below 60fps and backend services that live on the edge. I care about tactile interfaces, zero unnecessary SDKs, and codebases you can still understand three years from now.

Who is Mattz?

I am a software engineer obsessed with how software feels under the thumb and how it behaves when network connections are terrible.

Most modern mobile apps feel heavy because developers import massive libraries for problems that need twenty lines of clean code. I take the opposite route: explicit state control, custom painters when the framework falls short, and strict rebuild boundaries so your phone never heats up doing basic tasks.

On the infrastructure side, I avoid bloated origin servers whenever possible. I push routing, auth checks, and relational queries straight to Cloudflare Workers and D1 databases close to the user.

Framerate is non-negotiable

If an animation stutters during a customer presentation or checkout flow, the engineering failed. I profile frame rendering times down to microseconds.

Offline is a feature, not an error

Apps should work underground, on planes, and in warehouse basements. Local SQLite and queue sync beat loading spinners every single time.

Small dependencies, long shelf life

I choose proven libraries and write standard Dart, TypeScript, and Go so projects stay maintainable without breaking on minor updates.

Direct technical communication

No corporate jargon or layers of management. You talk directly with the engineer building your product.

What Mattz Has Built

A selection of real systems engineered for production reliability and responsive interaction.

Mobile & Flutter

Horizon Mobile Logistics Client

An offline-capable Flutter app built for barcode scanning and package sorting. Keeps working in concrete basements by committing to SQLite first and syncing when signal returns.

Cloud & Edge

Cloudflare Edge Proxy and REST Gateway

An Anycast reverse proxy that authenticates requests at edge nodes and queries Cloudflare D1 tables directly, saving round trips back to central servers.

Web Frontends

Monochrome Liquid Glass UI Toolkit

A responsive component kit for Next.js and React 19. Uses pure black and white with SVG refraction maps to create tactile depth without bogging down the browser.

Realtime WebSocket Telemetry Daemon

A Go background service coordinating message dispatch between mobile clients and Redis. Maintains steady throughput under thousands of concurrent connections with low memory usage.

How Mattz Thinks About Architecture

Good architecture is not about using every new framework on Hacker News. It is about choosing boring, reliable primitives that do not break at 3 AM.

Flutter Mobile Engineering

  • Fine-grained state management with BLoC and Riverpod
  • Custom RenderObjects and 2D canvas painting for unique components
  • Native Swift and Kotlin bridges when system APIs are required

Edge Cloud Infrastructure

  • Sub-millisecond worker routing on Cloudflare Anycast
  • Distributed relational data storage with D1 and global KV caches
  • Encrypted Zero Trust tunnels removing public port exposure

Backend Services in Go

  • Lean concurrent daemons managing real-time WebSocket pipelines
  • Redis pub/sub coordinating instant client state synchronization
  • Clear JSON and protocol buffer schemas with zero bloat

Accessible Web Frontends

  • Next.js 14/15 App Router pairing static generation with selective hydration
  • High contrast OLED styling that passes WCAG AA standards
  • Native keyboard interaction loops across all interactive elements
