Work experience

Full stack developer

from 10.2024 to 06.2026 (1 year 9 months)
Brightgrove LTD, Львів (IT)

•​ Set up and maintained CI/CD pipelines with GitHub Actions to automate build, test, and deployment across
the NestJS backend and Nuxt.js frontend, shortening release cycles for a multi-year digital transformation
spanning web, mobile, Smart TV, and POS systems.
•​ Designed and engineered GraphQL API endpoints consumed simultaneously by iOS, Android, and Tizen
clients, maintaining consistent data contracts across 4 platforms and reducing cross-platform integration
issues.
•​ Implemented business-critical features — real-time seat selection, ticket booking, and loyalty program
integration — translating product requirements from Product and Project stakeholders into technical
implementations.
•​ Wrote unit and integration tests with Jest for backend services and GraphQL resolvers, and used Sentry for
production error monitoring, reducing time-to-detect for critical booking-flow issues.
•​ Optimized PostgreSQL queries and schema design to support high-volume ticketing transactions, sustaining
reliable performance for a loyalty program with 700,000+ active members.
•​ Integrated AWS services (EC2, S3, Lambda, CloudWatch) to improve scalability and reliability of infrastructure
supporting 60%+ of the company's digital ticket sales.
•​ Built server-side rendered pages with Nuxt.js, improving initial load performance and SEO for customer-facing
booking flows.
•​ Coordinated daily with a 12-member cross-functional team (PMs, backend, iOS, Android, Tizen, and QA
engineers) to align API behavior and release timelines, reducing platform-specific bug reports across sprints.
•​ Participated in Agile ceremonies (sprint planning, standups, retrospectives), contributing to sprint estimation
and technical solution discussions.

Frontend Developer

from 05.2023 to 10.2024 (1 year 6 months)
Docca.io, Львів (IT)

•​ Developed and maintained full-stack features using React, Next.js, Node.js, and TypeScript for a platform
serving 5,000+ users, delivering reusable UI components that reduced duplicated code by ~25% across
application modules.
•​ Designed and implemented 15+ REST API endpoints for patient management, appointment scheduling,
document handling, and user profiles, enabling core platform workflows for end users.
•​ Diagnosed and resolved frontend performance bottlenecks using lazy loading, dynamic imports, and
component memoization, improving page load times by ~40% across the application.
•​ Wrote unit tests with Jest and integrated GitLab CI/Jenkins pipelines to run automated test suites on every pull
request, catching regressions before merge.
•​ Refactored legacy frontend modules into reusable custom hooks and shared components, working within an
existing codebase to simplify future feature development.
•​ Implemented JWT-based authentication and role-based access control (RBAC), securing platform access
across user roles.
•​ Maintained Docker-based development environments, resolving environment-specific configuration issues to
keep workflows consistent across the team.
•​ Investigated and fixed production issues reported by QA and end users through root-cause analysis,
prioritizing durable fixes over temporary patches to reduce recurring bugs.
