Why LSSTB

Quality and speed are not a trade-off. They're the same habit.

◆ Quality you can measure

  • Senior engineers only. Every line is written by someone with 8+ years of production experience. No juniors learning on your budget.
  • Reviewed and tested. Every change is peer-reviewed and covered by automated tests before it reaches you.
  • Performance budgets. We target a 95+ Lighthouse score and 60 fps on mid-range phones, and we check on every release.
  • You own everything. Code, designs, accounts and documentation are yours from day one.

▲ Speed you can plan around

  • Demo in 10 business days. Not slides. A working build you can click through and share.
  • Weekly releases. A new version lands on your staging link or test device every Friday.
  • Fixed scope, fixed price. You know the cost and the date before we write any code.
  • Replies within hours. You talk directly to the people building your product, in your time zone.

Process

From first email to launch in four steps.

  1. Week 1

    Discover

    We map your goals, users and constraints, then send a fixed scope, price and delivery date.

  2. Week 2

    Prototype

    You get clickable screens and a first working build to validate the direction early.

  3. Weeks 3–10

    Build

    Short sprints, a release every Friday, and a shared board where you can follow every task.

  4. Launch day

    Ship & support

    We handle deployment and store submission, then stay on for monitoring and improvements.
