Fullstack Developer
I build digital products from idea to production — from UI to architecture and infrastructure. 4+ years shipping commercial platforms, automation, and international products.
Open to remote work and international projects
Approach
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
Measurable business impact — not code metrics, but effects for people and processes
Whitewill
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
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
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.

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.

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.

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.

Frontend / Fullstack Developer
Over 4 years, grew from UI tasks to owning key modules of an international platform: search, catalogs, data automation, and Vue 3 migration — all without business downtime.
Owned frontend and fullstack work on a product serving 7+ markets at once. Designed search and filtering for different countries and property types, built fully automated catalog export, automated content and translation generation, and helped migrate critical sections to Inertia.js + Vue 3. My work eliminated manual labor that dozens of people did daily and made releases predictable for conversion.
Key areas
Led migration of core catalogs to Laravel + Inertia.js + Vue 3: service layer, typed DTOs, lazy props, and SSR for indexing. Critical sections moved without business downtime; pages remained full SEO units.

partners.whitewill.ru — B2B ecosystem with amoCRM integration
Evolved partners.whitewill.ru — a separate product where I owned backend and integration work. Contributed to the points and public ranking system, bidirectional amoCRM sync, admin dashboard with 20+ filters and async Excel export, personal PDF/PPT reports, and partner SSO access to the Whitelist catalog.

Frontend Architect
Designed Web3 platform frontend architecture from scratch: Next.js, real-time, Django integration, and processes for a growing team.
Joined at an early stage when the product was built practically from scratch. Established Next.js architecture with SSR/SSG, set up WebSockets for real-time data, designed contracts with the Django backend, introduced typing and CI/CD. Built complex interfaces with GSAP and Three.js while keeping the codebase scalable as the team and feature set grew.

Fullstack Developer
Built a fullstack mindset: from UI to backend, data automation, and products used daily by real customers.
Started as a developer and quickly took on end-to-end work. Built a product for Kaspi.kz sellers — tracking products, prices, and stock with routine automation. Created large-scale data collection and processing for major e-commerce, and developed solutions for automotive and fuel industries. This is where I learned to own the full outcome, not just my slice of code.
Expertise
Real experience across product layers — no abstract diagrams

Competencies
Not just a tech stack — real systems I designed, evolved, and brought to production.
Designed and evolved the server side of large products: service layers instead of monolithic controllers, typed contracts between backend and frontend, multi-region business logic, and external integrations. Built automated catalog processing pipelines, real-time via WebSockets, and backend for partner platforms — all in production, under real load, with stability required for daily data updates.
Multi-region real estate platform — one product for 7+ markets with distinct logic, currencies, and languages
Real outcomes
Tap for results
Built client applications that stay fast and maintainable as products grow: public catalogs, complex search UIs, admin panels, and Web3 interfaces. Led legacy migration to Inertia.js + Vue 3, shipped SSR for SEO, TypeScript typing, and component architecture where business logic isn't scattered across the UI. For me, frontend isn't page markup — it's the layer through which users interact with the entire system.

Real outcomes
Tap for results
Designed platform architecture end to end: how to split responsibility across layers, launch new markets without code duplication, and connect frontend, backend, CRM, and data flows into one predictable system. Led deep transformations of live products — legacy migration, content automation, partner ecosystems, and reducing tech debt while the product already serves thousands of users.
