Approach

Systems, not components

For me, development is building a system where every part works predictably and is ready to grow over years.

My core skill is diving into business domains and finding solutions that deliver real value.

Impact

What changed because of my work

Measurable business impact — not code metrics, but effects for people and processes

Whitewill

Automated catalog instead of manual labor

7

markets with zero manual export

4 update cycles daily (3 syncs + full morning export), price recalculation in 7 currencies, photos, translations, and admin pages. Work dozens of employees did manually now runs on schedule across all markets.

Whitewill

Property publishing for managers

1

click instead of hours of manual entry

Descriptions, parameters, SEO blocks, and multi-language translations are generated automatically after each export. Managers went from manually filling cards to review and publish — minutes per property, not hours.

Whitewill

Partner channel analytics

20+

filters and thousands of rows per report

Admin dashboard with flexible filtering and async Excel export — managers export thousands of partners and clients without timeouts. Bidirectional amoCRM sync keeps the partner portal and CRM as one system.

Whitewill

Unified search without release regressions

7+

markets — one search engine

One filtering engine for different countries, property types, and business rules. After E2E tests on critical flows, search stopped breaking on releases — conversion became predictable with each deploy.

Whitewill

Catalog migration to a modern stack

0

days of business downtime

Critical sections migrated to Inertia.js + Vue 3 with SSR while thousands used the platform daily. The business kept running; SEO pages remained full units for organic traffic.

Teknolab

Product for Kaspi.kz sellers

100%

seller routine — automated

Dashboard for tracking products, prices, and stock: daily routine operations sellers did manually are now automated. The product became a daily work tool, not a one-off Excel task.
