Logan Biesterfeldt
Senior Frontend Engineer · UI/UX Specialist · Web3 Product Innovator
I design and build high-performance, user-centric interfaces for smart contract-powered decentralized applications—bridging technical precision with product-driven design.
My work spans DeFi platforms, DAO tooling, and on-chain analytics, backed by years in web development, branding, motion graphics, and marketing. Previously, I crafted educational experiences and protocol visuals with stake.fish and f2pool.
Neptune Finance
Most of my experience with modern frontend frameworks comes from leading the development of the Neptune Finance web application — a borrowing and lending platform built with CosmWasm and deployed on the Injective blockchain. My responsibilities have spanned across frontend engineering, UI/UX design, branding, deployments, and overall user experience strategy. I also led the development of the Neptune Landing site. For the landing pages, I adopted a creative approach to design, integrating time-series data of interest rates into the visual elements to highlight the core focus of the lending market.
The interface is developed using Next.js and Tailwind CSS, with additional UI components from Material UI and Daisy UI. I've also utilized Figma and Midjourney to establish the product's visual identity and design language. To streamline design and development, I built a custom Figma component library and created reusable assets for marketing materials.
Recent work includes launching Staking and Airdrop pages in support of the NEPT token release, and building Pool pages that integrates Mito and Astroport smart contracts and LP tokens. I introduced novel UX patterns to improve the user experience around liquidity management and implemented gated protocol features for NEPT stakers.
