Software develpment student - Solvd, Inc. → visit github repo and live page

Check course → https://laba.solvd.com/reactjs

Selected for a six-month programme aimed at training and evaluating candidates for front-end developer roles. This process involved recurring code submissions and screening tests for each block.

I strengthened my knowledge of React, Next.js, TypeScript, Zustand, TanStack Query, and Material U Software engineering principles (SOLID, DRY, KISS), Git branching strategies, code reviews, unit testing, and e2e testing were applied.,

I worked in an Agile/Scrum environment, participating in sprint planning, daily meetings, and collaborating with peers.

The project culminated in the team delivery of an e-commerce project with authentication, Stripe payments, CMS integration, and AI-powered features.
