System Design: Justine Longla T. Ecosystem
How I unified the Justine Longla T. main hub, blog engine, and documentation site into a consistent, reliable multi-site ecosystem — with shared branding, predictable routing, and independent CI/CD pipelines.
One ecosystem, many sites
Instead of patching symptoms, I redesigned the setup as a distributed system: stable interfaces, predictable pipelines, and clear boundaries between marketing, content, and documentation.
Role
Platform Architect · DevSecOps Engineer
Tech Stack
Next.js, GitHub Pages, Vercel, GitHub Actions, DNS/IONOS, CI/CD pipelines, versioned assets, branding system
Highlights
Multi-repo platform · Consistent dark/light themes · Reliable subdomains · Unified UX · Independent deployments
Overview
As the ecosystem grew — the main site, documentation, custom blog engine, and multiple subdomains — branding inconsistencies appeared. Gradients, images, buttons, routing, and deployment behaviour drifted across repos.
The solution was to treat the sites as services in a platform, not isolated experiments: shared patterns, clear contracts, and automation.
Architecture
At a high level, the ecosystem now looks like this:
- Main marketing site on Vercel, owning first impressions, intro calls, and core offers.
- Blog engine on GitHub Pages + Vercel, with custom templates and a content pipeline.
- Docs hub as a static site focused purely on technical walkthroughs and reference material.
- Shared assets & brand: logo, gradient system, component behaviours, and typography agreed once and re-used everywhere.
Impact
Visitors now experience the ecosystem as one coherent brand, regardless of which domain they land on. Behind the scenes, each site keeps its own CI/CD pipeline and release cadence, so changes stay safe and traceable.
