OTAKOYI

OTAKOYI publishes 7 freely visible case studies that lean toward AI and full-stack delivery, with 6 of the 7 framed around engineering rather than design; the Coto Academy e-learning build is the one that documents a research-led design track, citing stakeholder interviews, competitor analysis, user surveys, a new information architecture, interactive prototypes, and a UI kit across a 17-month, 11-person engagement that reached 11,000 daily users in 100-plus countries.

The published UX/UI service describes a six-stage process through usability testing and design systems, but no case study is design-led, and homepage outcome claims such as $500k saved for Lenovo and a 35% capacity gain for PeteHealth are not backed by detailed public write-ups, so design work here usually arrives as one workstream inside a development engagement rather than a standalone deliverable.

Best for funded teams building data-heavy or AI products end to end that want one Ukraine-based partner to carry research-informed design through to the engineering build, provided you confirm up front where the design scope ends and the development scope begins.
