概要

Senior Front-End Engineer & Tech Lead working at the intersection of code, design, and blockchain and delegating everything I can to AI agents, at work and home. Based in Japan, collaborating remotely across APAC, EU, and US time zones.

14 years building scalable, secure and visually engaging front-ends. I lead the DevX & Design team at gno.land (the smart-contract platform from the team behind Cosmos and Tendermint) 6 engineers shipping dApps, wallets, developer tools, launchpads, and 3D experiences for the people building on-chain. The job, day to day, is to make complex on-chain systems feel intuitive.

But it's not just what we build, it's how we build. The team operates around AI orchestration: agents tracking meta-issues and surfacing blocking PRs, automated AI workflow such as multi-persona UX user-journey benchmarks to quick prototyping, custom skills, MCP servers, local LLMs alongside Claude...: The products aren't AI-powered, the work itself is. I shape product and architecture, code the parts that matter, delegate what doesn't need a human, and review what comes out. so the team can stay focused on what actually moves the product forward.

I started in creative engineering: immersive client work, awards (Awwwards, CSSDA, CSSWinner), the early Three.js era. Before Web3, everything from 3D sites and no-code MVPs to headless SaaS dashboards across DeFi, e-commerce, and B2B with React, Vue, TypeScript, Node, Go, and WebGL... These experiences taught me to be tech-agnostic, pragmatic, and curious, able to adapt fast and find the right solution for every challenge.

Open to: Staff Engineer, Tech Lead, Engineering Manager, or Head of DevX positions at serious protocols, AI-native dev tools. Real product, real users, real funding.

    Senior Software Engineer & Tech Lead FrontEnd: DevX

    All in Bits (AiB)

    – 現在 4年4ヶ月

    Tokyo, Japan

    Tech Lead of the DevX & UX team: 6 engineers shipping the dev tools, dApps and services that power gno.land and the broader Cosmos ecosystem.

    AiB is the team behind Tendermint Core, the Cosmos SDK, the IBC protocol (200+ chains + $6B+), Ignite, gno.land (first smart-contract platform running in Go), and AtomOne.

    Tech Lead of the DevX & UX team: 6 engineers shipping the dev tools, dApps and services that power gno.land and the broader Cosmos ecosystem.

    AiB is the team behind Tendermint Core, the Cosmos SDK, the IBC protocol (200+ chains + $6B+), Ignite, gno.land (first smart-contract platform running in Go), and AtomOne.

    I implemented new AI process so the team operates around AI orchestration layers I built: agents tracking issues and flagging blocking PRs across the team, autonomous AI workflows (e.g. UX benchmark pipeline running personas via RAG and scoring user journeys against UX laws via browser MCP), custom AI skills, and local LLMs running alongside Claude. The products aren't AI-powered. The engineering is.

    💡 CONTRIBUTIONS:

    — Gno Studio Connect: Web3 React/TypeScript dApp letting users connect wallets and interact with gno.land smart contracts through a clean, no-code interface for on-chain execution.

    — Gnoweb: led the front-end on a decentralized, secure on-chain web server for browsing, rendering and visualizing smart contracts, packages and source code across gno.land networks.

    — Gno Studio: React + TypeScript browser IDE bridging Web2 and Web3, letting developers write, test and deploy gno.land smart contracts directly in the browser.

    — Ignite Launchpad: front-end of a decentralized platform connecting new sovereign L1 Cosmos chains, validators and early holders for fundraising and token launches.

    — Emeris / AiB Chrome Crypto Wallets (DeFi): front-end framework, pipelining architecture and reusable component system.

    — GovGen & governance platform: voting, viewing and discussing chain proposals on-chain.

    — 3D Chess dApp: fully on-chain chess powered by Gnolang smart contracts, delivered in weeks for GopherCon 2023. Designed in Blender + Figma, built in Go, TypeScript and Three.js.

    — Airdrop Trackers for AtomOne, GovGen to simplify token distribution.

    — gno.land Faucet, Ops platform, plus all gno.land / AtomOne / Ignite docs and websites.
