Досвід роботи

Full stack developer

з 09.2019 по 02.2026 (6 років 6 місяців)
Global Logic, Дистанційно (IT)

- Drove end-to-end delivery of an enterprise e-commerce solution, partnering with UX stakeholders on Figma mockups, building responsive interfaces in React/Next.js with React Server Components, creating REST and GraphQL APIs through NestJS and Spring Boot, and shipping via GitHub Actions CI/CD to AWS ECS behind API Gateway.
- Replaced a legacy PHP/Laravel customer portal with a modern Next.js frontend backed by NestJS microservices, leveraging PostgreSQL for persistence and Redis for caching; server-side rendering noticeably improved page responsiveness during high-traffic windows.
- Engineered a data quality reporting service combining Django REST Framework and FastAPI, orchestrating nightly validation tasks through Celery workers with Slack alerting and PostgreSQL-driven operational dashboards.
- Partnered with the backend team to integrate a C#/.NET billing module, shipping ASP.NET Core APIs on schedule through Azure DevOps pipelines under tight delivery constraints.
- Decomposed tightly coupled orders and payments logic into standalone Spring Boot (Java) and NestJS (TypeScript) microservices, enforcing PostgreSQL data consistency across payment gateways via Prisma ORM.
- Introduced reliable asynchronous message processing using RabbitMQ with dead-letter queue handling, automatic retry mechanisms, and MongoDB-backed audit trails to guarantee zero order loss during peak sales periods.
- Stood up a production-grade DevOps workflow encompassing Docker containerization, Kubernetes orchestration managed by Terraform, GitHub Actions CI/CD, blue/green deployments on AWS EKS, and automated rollback procedures.
- Transformed release management from manual, off-hours deployments to routine business-hours releases by adopting Vercel edge deployment for the frontend and Jenkins/CircleCI orchestration for backend services.
- Created a React Native field service application alongside Flutter prototypes for technician use, featuring offline-capable SQLite synchronization with queued background uploads to DynamoDB and full-text search powered by Elasticsearch.
- Tuned database performance across PostgreSQL, MySQL, and Redis clusters through targeted indexing, RDS read replicas, pgBouncer connection pooling, and Celery-based background processing to sustain responsiveness during promotional surges.
- Rolled out an enterprise-grade observability stack featuring structured logging via Winston and Serilog, Prometheus-based metrics collection, Jaeger distributed tracing, and detailed runbooks spanning AWS, GCP, and Azure environments.
- Coached engineering teams on API best practices including DTO validation with class-validator and Spring, error handling conventions using Zod, and contract-first workflows via tRPC and GraphQL, enabling parallel team development without integration conflicts.

з 03.2015 по 08.2019 (4 роки 6 місяців)
United Tech, Дистанційно (IT)

- Built and maintained Laravel and Symfony API layers handling authentication, billing, notification dispatch, and reporting functionality across a portfolio of client-facing applications.
- Delegated compute-heavy operations to RabbitMQ worker queues and introduced Redis caching on high-read endpoints to preserve fast API response times under load.
- Shipped a React-based analytics dashboard featuring server-side rendering and route-level caching, delivering instant data retrieval and stable performance regardless of traffic fluctuations.
- Constructed a Nest.js reporting service backed by PostgreSQL, supporting streaming CSV exports and webhook callbacks to handle large result sets without triggering request timeouts.
- Developed a streamlined Django admin panel for the operations team, incorporating content moderation controls, guarded database editing, and comprehensive audit history.
- Packaged services in Docker containers and configured end-to-end GitLab CI pipelines covering linting, automated testing, and production deployment stages.
- Provisioned per-branch preview environments through Docker Compose, speeding up code review workflows and enabling faster stakeholder feedback loops.
- Delivered a partner-facing portal in Nuxt.js for a Vue-oriented internal team, backed by Symfony APIs complete with Swagger documentation and standardized error response formatting.
- Authored Python and SQL migration utilities to facilitate seamless data transfers and backfills during the transition from MySQL to PostgreSQL.

OSRAM, Дистанційно (IT)

- Built an internal inventory management dashboard combining a React frontend with an Express backend, incorporating role-based access controls and database audit logging for warehouse compliance.
- Wrote scheduled Python and SQL jobs for nightly inventory reconciliation, eliminating manual spreadsheet workflows previously relied upon by the operations team.
- Produced comprehensive REST API documentation with accompanying unit and integration test suites, empowering QA and operations staff to validate functionality independently.
- Deployed Redis caching for frequently queried inventory data, ensuring the interface remained responsive across multiple warehouse-connected devices.
