Co-founder, Eloqo · Barcelona, Spain

I build Eloqo, the AI speech coach in your pocket.

I'm Ilia Gordeev, a senior Kotlin engineer and co-founder of Eloqo. I build the product end to end: the Android and iOS apps, the Firebase backend and the Gemini review pipeline. Before Eloqo, I spent six years on the backend of an oncology patient-monitoring platform.

What I'm building

Eloqo is a gym for your speaking muscles.

Eloqo is a mobile AI speech coach. You record a short speaking exercise, such as an articulation drill, a monologue, shadowing or reading aloud. It scores clarity, fluency, vocabulary and confidence against the transcript, then names one thing to fix next.

  1. 01

    Record a short take. One to three minutes, from tongue twisters to retelling a text from memory.

  2. 02

    See instant numbers. Pace, filler words and hesitation pauses are calculated on the device, free and without an account.

  3. 03

    Ask for a coach review. Gemini on Vertex AI scores the take, annotates the transcript and suggests the next exercise.

Built on Google Cloud from day one.

Every part of Eloqo outside the phone runs on Google Cloud and Firebase. The whole backend is serverless, so two people can run it.
