How we work

Four stages, no black box

The same process for a two-week fix or a six-month build. You see every stage as it happens.

  1. Discover

    A working session to understand the actual problem, the constraints, and who's going to use this — before we propose anything.

  2. Design

    Architecture decisions and UI prototypes get reviewed with you in plain language, before a single line of production code ships.

  3. Build & test

    Two-week sprints, a live staging link you can poke at anytime, and QA running alongside development — not bolted on at the end.

  4. Launch & support

    Launch backed by a 30-day warranty, then ongoing monitoring, updates, and emergency response if something breaks.

Why DEESU

Four things that hold up

Not brand promises. The habits we apply on every project, checked whether or not you're watching.

Talk to the engineers

No account manager relaying messages. You're in the same channel as the people writing the code.

A clear quote, two-week sprints

A transparent breakdown after a free consultation, then two-week sprints against a live staging link.

40%

Faster than average

Security built in

Encrypted data handling and GDPR-conscious practices on every build, not bolted on afterwards.

100%

Encrypted by default

Support after launch

A 30-day warranty on every delivery, then monitoring, updates and hotfix response if you want it.

FAQ

Questions we get a lot

Straight answers about timelines, process and what happens after launch.

Still have a question, or need something custom?

Talk to an engineer

Most projects run 6 to 16 weeks depending on scope — you get a real breakdown during discovery, not a guess. Sprints keep delivery predictable, and rush timelines are possible with dedicated resourcing.

Five phases: Discovery, UI/UX Design, Development, QA Testing, Launch & Support. You get weekly updates, access to a live staging environment, and a direct line to whoever's running your project — no relay through account management.

Every project ships with a 30-day warranty covering bug fixes at no extra cost. After that, maintenance plans cover monitoring, security updates, feature work, and 24/7 emergency response if you want them.

React, Next.js, and Node.js on the web side; Kotlin and Java for Android; Python/Django and Flutter where they fit. Infrastructure runs on AWS, Azure, or GCP with Firebase, PostgreSQL, or MongoDB depending on the data model. We pick based on the problem, not habit.

Fixed-price or time-and-materials, depending on how well-defined the scope is. You get a transparent breakdown with milestone-based payments after a free consultation — no hidden fees added later.
