Alexandr Sokolov

Own the frontend of two products: Tourseta (tour-operator booking platform, 130+ pages, team of 5–8) and Readyhubb (services marketplace).

Tourseta: public booking site plus operator dashboards — tours, bookings, invoices, payments. Next.js/React on the frontend, shared packages for UI, bookings, money, and i18n in a monorepo.

Frontend is my main focus, but I also take backend tasks (~30% of the time): NestJS + Prisma on PostgreSQL, AWS (S3, SQS, Lambda for file processing and PDF rendering), JWT auth with roles, Swagger, Sentry, Docker.

Added payments (Stripe, Airwallex), PDF generation (invoices, vouchers), transactional email (SendGrid + react-email), and multi-currency / multi-language support end to end.

Optimized load speed — noticeably faster on the slow connections some operators use.

Readyhubb: built the admin and dashboards with no-code content management, so the team launches campaigns on its own.

Owned 4 of 11 packages in a Turborepo monorepo (team of ~15): Projects, Pages, Flow, and Meet (LiveKit video).

Shipped 15+ product features — from sprints and kanban to a project-creation wizard.

Made heavy screens (task lists, kanban) ~2× faster — virtualization, memoization, fewer re-renders.

Mobile adaptivity of key screens; unified i18n for shared components (Mantine 8, i18next). Stack: React 18, Vite, Zustand, Redux Toolkit, TanStack Query.

Led the frontend of a school-bus operations product (routes, schedules, bus and driver tracking): admin app, parent portal, and the company website.

Refactored an old, hard-to-maintain codebase incrementally without pausing production: upgraded React, moved class components to functional, Webpack → Vite (dev rebuilds ~12s → near-instant), server state → TanStack Query, TypeScript across the codebase.

Rebuilt the company website from scratch on Next.js — SSR, server-side data fetching, SEO — and shipped it to production.

Result: heaviest screens load up to ~7× faster, fewer bugs; set up project structure, code style, linters, and automated checks for the team.

Joined a product before launch and took it to production.

Built a no-code page builder in the admin (sliders, carousels, event grids) — marketing ships landing pages in hours instead of days, without a developer.

Sped up page loads by ~30% through caching and rebalancing work between server and client.

Extracted shared components into packages reused across 3–4 studio projects; added accessibility (high-contrast themes, font-size controls); mentored juniors and ran code reviews.

Built Adtomic — Amazon advertising automation: sellers manage campaigns, bids, pricing, and competitor tracking in one place instead of spreadsheets.

Built an internal UI library (a few dozen components) reused by 4+ teams.

Built data-heavy dashboards: tables with thousands of rows, charts, and real-time bid updates over live Amazon data.
