Work experience

Senior Software Engineer

from 02.2023 to now (3 years 10 months)
N-able Technologies, Дистанційно (IT)

•Designed and built an Angular 19 micro-frontend system end-to-end (Vite + Module Federation) for the company's PSA (Professional Services Automation) billing integration (host shell plus the federated remote), letting MSP partners connect external PSA platforms (HaloPSA) over an Apollo Federation GraphQL layer with SSO.
•Solved the federation's hardest problems: loading remote applications at runtime with graceful fallback, aligning shared framework dependencies (singletons) across the boundary, and a bespoke host/remote event contract carrying a single setup wizard across two independently deployed apps.
•Diagnosed and fixed elusive runtime failures at the host/remote seam: dependency version drift causing injector errors, wizard step re-entrancy, and change-detection issues, stabilising the shared component boundary and reducing recurring production defects.
•Delivered major features to a customer-facing self-service checkout application (React 18 + TypeScript, Zustand, React Router, Formik/Yup, MUI, Vite): refactored the journey from single- to multi-product, migrated pricing onto the company's product-catalogue and pricing services, and introduced its unit-test coverage and CI.
•Migrated the core shared UI library from Angular 15 to 19 across dependent applications and delivered five enterprise Angular (17–19) apps on the shared platform.
•Integrated AI-assisted engineering (Claude Code) into daily delivery: codebase analysis, code review, refactoring, and defect detection, increasing review depth and speed.

Senior Software Engineer

from 01.2022 to 01.2023 (1 year)
Grid Dynamics, Дистанційно (IT)

• Built the front end of a mission-critical internal application for managing employee security access to projects and documents, from initial architecture through production delivery.
• Delivered a cross-platform UI adopted by over 1,000 active users, balancing usability with the security-sensitive nature of the data.
• Achieved strong unit-test coverage, strengthening code quality and long-term project stability.

Front-end developer

from 07.2020 to 02.2022 (1 year 8 months)
EvApps, Дистанційно (IT)

• Developed and maintained a critical web hub for one of the world's largest urban underground transport systems, building the user-facing subsystems for travel information and payment processing.
• Built a specialised UI subsystem for contractor management, enabling secure access to the Metro Data Centre for outside personnel.
• Designed a cryptography module for public key infrastructure (PKI) on a large-scale state project, strengthening system security.

Front-end developer

from 01.2018 to 07.2020 (2 years 7 months)
PromMetiz, Полтава (Металургійна промисловість, металообробка)

• Redesigned the company website end-to-end, improving the UI and implementing SEO optimisations that increased online visibility.
• Built a high-performance UI for the company's online shop, including a document-flow system that simplified user interactions.
• Developed a data-sync system connecting the accounting database to the online shop, keeping pricing consistent across both.
• Built 20+ reusable plugins that accelerated development across multiple internal systems.
