CHUBAROV VLADISLAV

I build web interfaces and developer tools, from product requirements to working applications. I’m open to frontend projects and collaboration with product teams.

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

MY ROLE

Full frontend implementation

STACK

React, TypeScript, Redux Toolkit, RTK Query,
Ant Design, Ant Design Charts

THE CHALLENGE

A pricing recommendation needs context. A number alone does not show which hotel, room category, rate plan and date it belongs to — or whether bookings are ahead of or behind the reference pace.

My task was to connect the filters, recommendations and booking charts in one frontend, including 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 keep every view tied to the right 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, with the actual total, reference value and pace ratio shown together.

THE RESULT

I built the complete frontend, connecting the pricing calendar, recommendations and booking analytics into one workflow with API integration and 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, with shared engines for the web app, CLI, plugins and AI-agent skills.

MY ROLE

Solo design and development — interface, engines, APIs and integrations

STACK

React, TypeScript, WebAssembly, Node.js, pnpm workspaces

THE TASK

Bring repetitive asset preparation and code utilities into one toolkit.

I built the complete product, with shared processing engines across the web app, CLI and integrations.

An AI-powered platform for assessing English writing and speaking. Users complete tasks and receive skill-level results; a connected Moodle plugin supports the exam-review workflow.

MY ROLE

Frontend contributor in a team of frontend developers

PRODUCT

Writing and speaking assessment, results and Moodle integration

THE TASK

Make English writing and speaking assessment accessible through a clear web interface.

I implemented part of the frontend within a development team, contributing to the assessment platform.

INSPECTRA

A gamified platform for learning how the web works through interactive challenges, articles, profiles and achievements.

MY ROLE

Complete code implementation with Ruby on Rails.

CONNECTEAM

A knowledge platform for IT teams, bringing together articles, practical cases, quizzes and an idea generator.

MY ROLE

Complete code implementation with Next.js, React and TypeScript.

Across these projects, I turn complex requirements into interfaces people can use — from analytics and learning platforms to developer tools.
