How we work

From first contact to launch and beyond — four predictable steps.

  1. Step 01: Inquiry & 30-min call

    Send us a message. We schedule a 30-minute online call within 2 business days.

    • Your timezone or JST
    • English or Japanese
  2. Step 02: Scoping & quote

    Within 1 week, we send a written quote with scope, deliverables, and a phased timeline.

    • Phased delivery plan
    • Invoice in USD or JPY
  3. Step 03: Build with weekly demos

    We share a working build every week, plus a recorded demo and change notes — so you can track progress without standups.

    • All commits visible on GitHub
    • Demos with English captions
  4. Step 04: Launch & operate

    We launch with you, then optionally stay on as the operations team — or hand off to your team with bilingual documentation.

    • Optional monitoring & ops retainer
    • All docs in JP & EN

Why Cyberneura

Four reasons international and domestic clients pick us.

Continuity

Same engineer, end to end

The person who scopes your project is the one who builds and operates it. No account-manager handoffs, no information loss, immediate technical decisions.

E-commerce expertise

10+ years of e-commerce & inventory automation

We have shipped Shopify and MakeShop stores, inventory / fulfillment / WMS integrations, POS systems, and order automation for over a decade. We design for peak season from day one — not after the first outage.

Bilingual delivery

JP / EN across the whole delivery

Specs, API docs, code comments, and handover notes — all available in either English or Japanese. Hand off naturally to a JP team after launch, or work with us entirely in English from the start.

Reliability first

We choose stacks for reliability, not novelty

We pick boring, battle-tested tools over the latest hype. SvelteKit, Astro, Django, Cloudflare, AWS — stacks we have run in production through outages, migrations, and scale-ups, not just in slide decks.
