I am a highly skilled and reliable software developer with a strong background in web and blockchain development.
Working as a full stack developer for up to 7 years, I have developed a wide range of web solutions using a variety of programming languages, frameworks and databases. I’m well versed in JavaScript and Python while I excel in statically typed languages like TypeScript. I’m a big fan of React.js when it comes to the frontend, and am proficient in various React-based frameworks like Next.js and Gatsby.js. I’m familiar with Node.js/Python based backend frameworks as well as various SQL and NoSQL databases like MongoDB and graph databases.
I have a solid understanding of blockchain infrastructure and have built many blockchain-integrated web solutions using web3.js and ethers.js. As a game enthusiast, I have created many web games and have written smart contracts using Solidity and PyTEAL for Ethereum and Algorand. Based on my strong background in mathematics and trading, I’ve created several trading bots running on various platforms like Uniswap.
Throughout my career, I have worked in different team cultures and workflows, and have a proven track record of success. Being a highly adaptable and excellent team player, with strong sense of ownership and responsibility, I am confident that I would be a great addition to any team or any project.
My tech stack mainly includes the following.
• React.js, Next.js, Gatsby.js, TypeScript, Material UI, Tailwind CSS
• Node.js, Express, NestJS
• Python, Django, Flask, FastAPI
