UkraineWhat I'm looking for
I’m a Senior Software Engineer with nearly 10 years of experience specializing in Angular and modern front-end development, with full-stack depth using Node.js. I’ve delivered robust, scalable applications for global companies by integrating Angular for the frontend and Node.js for the backend, backed by MongoDB and PostgreSQL.
I’m especially proud of building and shipping high-impact product features—like ClickUp Version 3 to 18+ million customers, creating an Audit Logs system from scratch, and optimizing a Task View load time by 20% with Cypress-covered E2E reliability. I also bring a competitive, results-driven mindset as a top-six finalist in Ukraine’s DEV Challenge IX and a finalist in the European IT Challenges, and I stay current with AWS by holding AWS Solutions Architect and Developer Associate certifications.
