Dear Hiring Team,

I am a full-stack developer with 10 years of experience in web and blockchain development. I have a proven track record of delivering high-quality projects and have worked on a variety of websites and applications.

I have experience using a variety of front-end technologies such as React, Next.js, Vue.js, and SolidJS, as well as CSS frameworks and UI libraries like Tailwind CSS, SCSS, Bootstrap, Material UI, Ant design, and more. I am proficient in server-side rendering, lazy loading, and increment static loading.

I am also familiar with backend development and blockchain/solidity programming. I have used Node.js, ExpressJS, Nest.js, Python, Flask, and Django as backend frameworks, and have worked with RESTful, Apollo GraphQL and gRPC as API standards. I have experience with ORM tools like TypeORM, Sequelize, and Prisma for managing SQL databases, as well as databases such as PostgreSQL, MySQL/MariaDB, and MongoDB.

I have experience with testing tools such as cypress, Jest, and mocha/chai, and have used Jenkins for automated builds and testing. In the event of any issues, Jenkins automatically informs me via Slack. I have experience uploading final packages to AWS Elastic Beanstalk, which manages infrastructure provisioning, load balancing, and scaling of resources such as EC2, RDS, DynamoDB, Redis, Lambda, Lightsail, Route53, and others.

I have implemented social media logins like Google, Facebook, Apple, and Twitter in several projects, and have experience with mobile app development. I am a self-driven developer with excellent problem-solving skills and always strive to find the best solution for each project.

I have also great careers in web3 development by developing the NFT mint landing pages, NFT marketplaces, Token Swapping site, DAO, Metaverse, etc on the EVM, Solano, and Cardano.
Developed the Defi Token, NFT(ERC721, ERC721A, ERC1155), NFT marketplace contract, reward, redeem, airdrop contracts with Solidity.
Implemented web3 integration with FE or BE by using web3.js or ethers.js.

I am confident that I can bring my technical skills and dedication to your project and look forward to the opportunity to discuss it further with you in the near future.

Thank you for your time.

Best regards,
Artur
