Andrii Haluza
Nodejs Developer
In a 7-year career as a JavaScript/NodeJs developer, I've worked on various projects in different domains: Dating, E-commerce, Marketing and Advertising, Entertainment, CRM\ERP Systems, Health and Wellness, and Task-Based Platforms. Used major technologies: NodeJs, JavaScript, TypeScript, Express.js, Koa, Nest.js, Strapi, PostgreSQL, MariaDB, MySql, MongoDB, Redis, React, Vue, Next, Nuxt, GCP, AWS, Cloudflare, ElasticSearch, Kibana, DataDog, CI\CD, Docker, Proxmox, Nginx, Swagger, Postman. I've handled typical software engineer responsibilities like: designing and integrating new features, fixing issues by debugging, refactoring outdated code, maintaining existing legacy, improving performance, covering code by tests (not so often as I wish), delivery and deployment and communicating with a team (in some cases with a client). Also, I had experience as a lead developer in a team; Currently, I'm aiming to enhance my technical expertise and move along in a staff engineer career path.
