Arjuna Marcelino

I’m a software engineer with a strong focus on Web3 development and quality assurance. I enjoy building meaningful and impactful digital solutions, particularly those that leverage blockchain to create new user experiences.

I currently work part-time as a Full Stack Developer at Monklabs, where I focus on frontend development for Web3 platforms using Next.js. I’ve worked on projects like a decentralized fan engagement platform that integrates Ethereum smart contracts with wallet-based authentication, token-gated content, and real-time interactions using wagmi and ethers.js. I’ve also contributed to a blockchain-based proptech platform that facilitates property listings and transactions on-chain.

What drives me is the opportunity to solve real-world problems using scalable, future-oriented technologies. During ETHGlobal Bangkok 2024, I co-developed Sawatreekap, a blockchain-based climate action platform that gamifies tree planting and tracks carbon credits via NFTs. It won the Runners-up prize for Best Social Good Application from Polygon Labs.

My background also includes significant experience in QA engineering and test automation. I bring a rigorous testing mindset into every development cycle to ensure that the systems I build are not only functional but robust and reliable.

I’m passionate about combining clean code, efficient user experiences, and impactful technologies—especially in the Web3 and AI domains—to build products that people actually use and benefit from.
