I design it, ship it, and stand behind it.
I'm Rento. I design and build the whole thing, end to end.
Design
Luxury travel brand
A design system, held to the pixel.
Engineering
Global newsroom
A new storytelling format, built with the team inventing it.
Real-time
London exchange
Trading screens and the live data feed behind them, both ends of the wire.
Design earns the look.
Engineering earns the trust.
The same hands own both.

// design
It starts as craft.
The type, the grid, the motion. The empty states and the edge cases nobody notices until they're wrong. I draw all of it.
The system underneath gets designed in the same pass. Interface and code, shaped as one thing. Not two halves bolted together.

now the code that ships them.

Then I make it real.
From brief to production, one continuous hand.
No relay race, no baton dropped halfway. The hands that designed it write the code that ships it, so nothing gets lost in the gap between the mockup and the build.

- performancePerformance designed in from day one.
- real-timeReal-time systems where what's on screen always matches the source.
- releasesShipped in small, reversible steps. Boring releases, on purpose.
// security
And I harden it.
In fast-moving companies, AI writes the code. Someone still has to answer for it.
So nothing ships unreviewed. Security rules sit in the harness while it works, an audit pass sweeps the whole codebase after, and I close by hand what machines miss.
The lasting fix is upstream. I harden the harness itself, so the next build starts safer than the last.
// operate
I stand behind it.
Launch is when it meets reality. I watch how it behaves: what's slow, what breaks, what people actually do with it once it's real. And I keep shaping it from there.

I've done all this before.
One piece from each, picked on purpose: luxury, media, and finance. All three carried from brief to production, and beyond.
luxury
A luxury travel brand
The visual bar left no margin. I built the front end as a real design system, component by component.
media
A global news network
A new mobile storytelling format, and the publishing system behind it, built to load under hard limits.
finance
A London exchange
The trading interface, the operations dashboards, and the real-time backbone feeding them all. One data layer, every screen current the moment the market moved.
Feedback is the next brief. Which is where design starts again.
If it has to look right, feel right, and hold,
tell me what you have in mind.
I'll tell you, honestly, if I'm the one to build it.
