What we deliver

UX/UI for complex products — not landing-page décor

One clear path from research to handoff. We design the products we also build.

Research & UX audit

Users, jobs, and constraints — or a prioritised audit of an existing product as a low-cost start.

Flows & information architecture

User flows and structure for dense business logic before pixels get expensive to change.

Wireframes & prototypes

Clickable prototypes that show behaviour — for stakeholder alignment and usability checks.

Visual design & systems

High-fidelity UI and component systems for dashboards and operations software.

Accessibility & bilingual UI

Contrast, keyboard use, and Swahili/English string planning for real Tanzanian users.

Developer-ready handoff

States, components, and behaviour specs so engineers build without guessing.

Tools we actually use

Figma FigJam Miro Maze
Assisted Engineering

Human judgment. Agent-accelerated drafts.

For dashboards and workflows: agents explore variants; designers own flows, accessibility, and handoff quality.

  1. Decide

    Humans set problem, users, and success metrics. Agents help gather structure options.

  2. Build

    Agents accelerate wireframe drafts. Designers own IA and interaction design.

  3. Verify

    Prototype and usability reviews. Humans accept or reject before polish costs stack up.

  4. Ship

    Implementation-ready handoff — specs, states, and behaviour for engineers.

FAQ

UX/UI design in Dar es Salaam — common questions

How long does a UX/UI design project take?

A focused design sprint takes about 2 weeks. A full product design with research, high-fidelity screens, and handoff typically runs 4–8 weeks depending on screen count and stakeholder reviews.

Do you offer a UX audit for an existing product?

Yes. A UX audit reviews your current screens and flows and gives a prioritised list of fixes — a low-cost starting offer before a full redesign.

Do you design for accessibility?

Yes. We check contrast, keyboard use, focus states, and readable text as part of every design review, aiming for practical WCAG-minded outcomes.

Does AI replace your designers?

No. Agents help draft variants and speed exploration. Designers and engineers own research judgment, accessibility, and what gets handed to development.

Can you design for complex internal tools and admin systems?

Yes. That is one of our strengths — dense workflows, permissions, approvals, reporting, and business logic that do not fit marketing-site patterns.

Do you design Swahili and English interfaces?

Yes. We plan for bilingual labels, longer Swahili strings, and mobile-money UX patterns common in Tanzania.
