Work experience

Full stack developer

from 07.2024 to now (2 years 4 months)
FINTECH COMPANY (NDA), Дистанційно (IT)

Enterprise CRM platform for workflow automation, reporting, access control, and internal business
operations.
• Defined a shared authorization model for three user types with granular and multi-role
permissions, keeping UI visibility, API access, and backend validation aligned as new workflows
were introduced.
• Structured React features and NestJS domains around business workflows so changes to
reporting, administration, or access control could remain isolated instead of affecting unrelated
parts of the CRM.
• Reworked performance-sensitive React flows by reducing unnecessary state propagation,
isolating expensive renders, and splitting application code to keep data-heavy CRM screens
responsive as state complexity grew.
• Designed real-time synchronization for changes originating outside the active client, keeping
dashboards and workflows aligned with server state without relying on manual refresh.
Stack: React, Next.js, TypeScript, NestJS, Redux Toolkit, PostgreSQL, REST APIs, Socket.io,
Docker, Google Cloud

Senior Software Engineer

from 06.2022 to 07.2024 (2 years 2 months)
CRYPTOPERK — WTT, Дистанційно (IT)

Structured state across social, wallet, transaction, and analytics domains so independent
asynchronous APIs could update related data without leaving the client in inconsistent states.
• Separated API interaction, state transitions, and presentation logic, allowing new product flows to
reuse established behavior instead of increasing coupling between screens.
• Integrated reward flows connecting user activity with platform currency and cryptocurrency
wallet operations while keeping financial and UI state synchronized.
Stack: React, Vite, TypeScript, Redux Toolkit, React Router, SASS, Formik, Magic SDK, Recharts, REST
APIs

Senior Software Engineer

from 04.2021 to 02.2022 (11 months)
EZLO — SMART HOME PLATFORM, Дистанційно (IT)

Modernized a legacy React 15 production application incrementally, introducing newer React and
TypeScript patterns without requiring a disruptive full rewrite.
• Increased TypeScript coverage and added Cypress protection around migrated flows, catching
contract and interaction regressions while legacy and newer modules continued to coexist.
• Unified device automation behind a Trigger → Conditions → Action model and used WebSocket
synchronization for device state that could change independently of the active browser session.
Stack: React, TypeScript, Redux, Material UI, Cypress, WebSockets, Socket.io, REST APIs

Full Stack / Frontend Engineer

from 10.2019 to 03.2021 (1 year 6 months)
AVANTIZE, Дистанційно (IT)

Extended CRM authorization to four access levels with multi-role accounts, keeping permissions
consistent across navigation, UI actions, APIs, and financial workflows.
• Built financial dashboards, reporting, and large-file upload flows up to 1 GB with dedicated
handling for progress, long-running operations, and failure states.
• Expanded into Node.js/TypeScript backend development for posts, short-form video, chat,
relationships, and content interactions backed by PostgreSQL and Sequelize.
Stack: React, Node.js, TypeScript, Redux, Redux Saga, Feathers.js, PostgreSQL, Sequelize,
Docker, Google Cloud

from 10.2017 to 10.2019 (2 years)
Poputchik, Дистанційно (IT)

Frontend Developer | Nov 2017 – Oct 2019
• Built reusable React and Redux patterns across commercial products, replacing repeated screenlevel implementations with shared component and state behavior.
• Delivered REST-integrated responsive interfaces across multiple products, establishing the
frontend foundation for later work in complex state, real-time systems, performance, and fullstack architecture.
Stack: React, JavaScript, Redux, React Router, Material
