Throughout my career, which spans more than 8 years, I have developed a wide range of software systems using a variety of programming languages, frameworks, and databases. My tech stack includes popular front-end frameworks such as React.js, Next.js, Angular.js, and Vue.js, as well as server-side technologies like Node.js, Express, Golang, Rust, Python and Nest.js. I am proficient in both statically typed languages like TypeScript and dynamically typed languages like JavaScript and am familiar with a range of databases including MySQL, SQL Server, MongoDB, and PostgreSQL.

I have a strong understanding of blockchain and smart contract technology, including Web3, Solana, Ethereum, and Truffle. I have experience with a range of decentralized applications and NFT marketplaces and am well-versed in the planning, implementation, testing, and maintenance of these systems. I have several years of experience in developing smart contracts with Solidity, as well as an extensive knowledge of various security patterns and the ERC1155, BSC and other tokens standard. I have been involved in numerous NFT projects over the years, helping to design and build secure, reliable smart contracts for them. My attention to detail ensures that all code is thoroughly tested before being deployed, limiting any potential bugs or vulnerabilities. I am also proficient in cloud platforms like Azure, Firebase, and AWS, and have experience with CI/CD tools like Jenkins, Git, and Docker.
