My Journey as a Frontend Engineer

Hey, I’m Oleksandr Antoniuk, a Senior Frontend Engineer with a deep passion for crafting visually appealing and high-performing web applications. My journey to becoming a programmer reflects my dedication and adaptability.

After earning my Master’s degree in Financial and Economics from Kyiv National Economic University in 2015, I initially pursued careers as a law consultant and later as a bank worker. However, I soon realized that these fields did not align with my interests. Determined to change my career path, I dedicated a year to intensive learning and self-study to break into the IT field.

My hard work paid off, and in 2017, I secured my first job as a programmer, marking the beginning of my journey in web development.

With over 7 years of industry experience, I have honed my skills in JavaScript and TypeScript and specialized in modern frontend frameworks such as Vue.js, Nuxt.js, Astro.js, and React.js. My career path is marked by a series of progressive and impactful roles, each contributing to my growth as a developer.

Professional Experience

Currently, I serve as a Senior Frontend Engineer at, a global online retailer for knitting, crochet, and other craft supplies. At LoveCrafts, we cater to customers all over the world, offering a vast array of products with diverse attributes. My primary responsibility has been to take part in the migration of our frontend from an outdated stack to a modern, composable architecture.

Our previous backend relied on Magento 1, with frontend components implemented using plain HTML and CSS. To modernize our stack, we transitioned to a headless backend using services like Commerce Tools for e-commerce, Akeneo for product storage, Amplitude for analytics, and Prismic for content management. The frontend was rebuilt using Vue.js with the Composition API and Nuxt.js for server-side rendering. This comprehensive overhaul was executed meticulously, migrating the project page by page and service by service, with each new feature undergoing rigorous A/B testing.

Key achievements in this role include:

  • Successfully migrating the checkout and payment systems, integrating Apple Pay and Google Pay.
  • Integrated a new payment provider.
  • Developed new content pages.
  • Improved search, product, and catalog pages.
  • Implemented unit tests with Jest and end-to-end tests with Cypress to ensure quality and reliability.
  • Participated in architectural decisions and conducting code reviews.
  • Implemented Cross-Site Request Forgery protection.
  • Implemented backend services with Node.js, Express.js AWS services such as EC2, Lambda, SQS, RDS, S3, Cognito, CloudFormation, and others.
  • Completed frontend migration and implemented multi-brand support.

Before joining LoveCrafts, I worked as a Software Engineer at (USA - remote) from December 2019 to December 2020. At, my focus was on automating development processes, deployment, and integrating code into the platform. I developed subprojects such as a content builder and data transformers, contributed to the UI library, and worked on serverless applications. This role allowed me to refine my skills in automation and enhance the efficiency of our development workflows.
