Interfaces for people doing real work: engineers, cashiers, butlers and commuters. Clear journeys, a system behind every screen and motion with a job to do.
Systems thinking.
Shipped as software.
/About Synthera

We design, engineer and secure the whole system,
from the first requirement to production.

/Our worlds
The fields
we work in:
Engineering, business, hospitality
and everyday life. Each asks something
different of a digital product.
/What we do
Design, engineering and cybersecurity.
One team, from the first requirement
to the product in people's hands.
Native iOS apps, web platforms and the services behind them. Live data, field work that keeps going offline and AI that answers from your own records.
Security designed in from the first sketch: gated access, hardened releases and sandboxed automation, with a rollback ready before anything goes live.
Native where it matters.
Web where it scales.
Swift and Flutter on the phone, TypeScript on the web,
Postgres underneath, Cloudflare at the edge.
We pick the stack around the job.
/How we build
AI-first delivery,
with engineers holding every gate.
Requirements first
Every brief becomes a numbered requirements register before a screen is drawn. On Atollio Works, 476 requirements became 146 build cards, ordered by dependency.
Built under gates
AI agents carry the volume inside sandboxes. Type checks, test suites and rule checks gate every merge, and nothing ships unreviewed.
Proven in production
Releases go out with evidence. Atollio's engineering release was accepted only once its offline steps ran end to end in WebKit and Chromium. Then it went live.
