CHUBAROV VLADISLAV

I am a frontend developer who builds web applications and developer tools. I work with React and TypeScript, transforming product requirements into functional interfaces.

I built the frontend for PredictStay, a hotel analytics product powered by Predict Core. The interface consolidates pricing recommendations, room availability, and booking pace into a single workspace, helping hotel managers review data before making a pricing decision.

THE CHALLENGE

A pricing recommendation requires context. A number alone doesn’t indicate which hotel, room category, rate plan, or date it belongs to—nor does it show whether the bookings are ahead of or behind the reference pace.

My task was to integrate the filters, recommendations, and booking charts into a single frontend, including implementing loading, error, and empty-data states.

CHANGE THE WORKING CONTEXT

Changing the room category updates the calendar, inventory, and recommendation details. The selected hotel, category, rate plan, and period ensure that every view remains tied to the correct working context.

COMPARE BOOKING PACE ACROSS DATES

The booking view compares actual bookings with a reference curve for the selected arrival date. Switching dates reveals different demand situations, showing the actual total, reference value, and pace ratio together.

THE RESULT

I built the complete frontend, integrating the pricing calendar, recommendations, and booking analytics into a unified workflow, including API integration and handling loading, error, and empty states.

A toolkit I designed and developed independently for preparing web assets and code. It brings image and SVG optimization, fonts, favicons, typography, and interface utilities into one product, featuring shared engines across the web app, CLI, plugins, and AI-agent skills.
