Three Pillars of Design Mainline
Engineering luxury into every layer — from the spaces you live in to the software you interact with.
Smart Environment Design

We design the experience. Licensed professionals handle the wiring.

Design Mainline specifies, programs, and integrates luxury smart home systems. We work with Savant, Control4, Crestron, and Lutron to create environments where lighting, audio, video, climate, and security respond to a single touch or voice command.

Our role is the technology architect: we design the system, select hardware, program automation scenes, and coordinate with licensed electricians and AV installers for physical installation.

  • Whole-home automation design & programming
  • Ambient & architectural LED lighting systems
  • Home theater & immersive audio rooms
  • Distributed audio/video (Sonos, Sonance)
  • Motorized shading & climate integration
  • Network infrastructure design (enterprise WiFi)
  • Smart security & access control specification
  • Outdoor entertainment & landscape AV

Technology Partners

Every project starts with a discovery session. We assess your space, define your needs, and blueprint a system before any hardware is purchased.

Custom Software Development

Production-grade applications. Zero to one.

We build web and mobile applications with modern, battle-tested stacks. Whether you need an MVP or a full SaaS product, we deliver complete, testable, deployable software — not wireframes that collect dust.

Our philosophy: ship a correct v1 today over a perfect v2 later. Every feature ships as a complete, testable unit.

  • React + TypeScript web applications (Vite, Vercel)
  • React Native / Expo mobile apps (iOS & Android)
  • Serverless APIs (Express.js, Node.js)
  • PostgreSQL database design (Neon, Drizzle ORM)
  • Authentication & identity (Firebase Auth, OAuth)
  • Real-time features & push notifications
  • CI/CD pipelines & deployment automation
  • UI/UX design & brand identity systems

Precision at Every Phase
From first conversation to final deployment — every step is intentional.

Discovery

We listen, audit, and define the problem. No work begins until scope is locked and success metrics are clear.

Architecture

System design, technology selection, and experience mapping. We blueprint every detail before a single line of code or hardware spec.

Build

Iterative development with weekly deliverables. Complete, testable units — never half-finished features.

Deploy

Production launch with monitoring, documentation, and handoff. We stay on through stabilization.

Founder & Engineer

Technology with taste. Engineering with intent.

Design Mainline is a luxury technology studio based in Southern California. Founded by Jason Hamilton, we sit at the intersection of smart environment design, full-stack software engineering, and digital product development.

We design intelligent spaces — specifying and programming smart home automation, ambient lighting, home theaters, and AV installations. For the build, we partner with licensed professionals to ensure every installation meets code.

On the software side, we build production-grade applications from zero to one. Our flagship, SkateHubba™, is a location-based social platform for skateboarders with patent-pending game mechanics.

Precision engineering, luxury execution, zero shortcuts.
