Stage 03 · Building
High-performance web platforms engineered to scale with the business.
Building fast, secure, and scalable web platforms that hold up as traffic, teams, and features grow.
The problem
Traffic and features grew, and the site that launched fine two years ago now buckles — pages crawl, visitors leave, and every change comes back quoted as a rebuild.
How Sumago approaches it
Performance-first front-end engineering on a clean, typed architecture — built to be maintained, not rebuilt.
Who this is for
If any of this sounds like .
Web Platform Engineering is usually the answer to one of these four conversations — not to a feature list.
- 01
The platform is buckling under its own success
Traffic and features outgrew the original build. Pages crawl, the codebase resists change, and every request comes back scoped as a rebuild.
- 02
Performance is costing measurable revenue
Slow pages are pushing visitors away and holding search rankings down — and nobody can point to which part of the stack is responsible.
- 03
The team is blocked by the codebase
Shipping is slow because the architecture makes every change risky. Marketing waits on engineering for edits that should never reach a developer.
- 04
A rebuild has to be the last one
You're prepared to re-platform once — provided what replaces it can be extended by your own team instead of re-bought in two years.
What you get
The artifacts an engagement .
Tangible things your team owns at the end — not a slide deck describing them.
- 01A performance budget and Core Web Vitals baseline
- 02A typed, component-driven codebase your team can extend
- 03A CMS your marketing team can actually run
- 04Deployment pipeline with a safe rollback path
What changes
The difference this makes to .
