I've built web applications and cloud infrastructure for Comarch, SmartCat, and Devrix, spanning frontend interfaces, backend services, vendor integrations, and serverless AWS architecture. At Comarch, I used AWS, API mocks, S3, Lambda, DynamoDB, and SNS/SQS to support integration testing and serverless implementations.
Across nearly nine years of full-stack development, I've delivered React, Node.js, Express, Vue, Angular, PHP, Python, and database-driven applications. I've also built real-time broadcast and chat services with Socket.io, integrated OpenStack APIs with AWS architecture, and developed microservice-oriented applications with React and Spring Boot.
