Vinsario Shentana

I’m an Informatics Engineering undergraduate who builds at the intersection of modern web experiences and emerging tech. I specialize in Web3 development and frontend engineering, with strong hands-on experience shipping features end-to-end.

In my current role as a Web3 Developer Intern at Manexus Technology, I develop and deploy secure smart contracts on Sui using Move, leveraging Sui’s object-centric model to optimize transaction efficiency. I also build and test EVM-compatible smart contracts in Solidity on the Katana network, and I integrate Sui Wallet and MetaMask so users can sign and authenticate seamlessly.

On the frontend side, I’ve delivered responsive, cross-browser interfaces and improved delivery speed through reusable components—helping development speed by 30%. I focus on performance, clean UI, and maintainable integration with backend APIs, including work that boosted user interaction on key pages by 25% through subtle animations.

I’m driven by collaborative problem-solving and continuous iteration. From an IoT self-service printing ecosystem bridging web submissions to physical kiosks, to secure e-commerce and document workflows, my projects reflect the same goal: build trustworthy systems that feel fast, clear, and easy to use.
