Technical Skills & Tools
A snapshot of my go-to frontend stack, from building scalable UIs with React, Next.js, and TypeScript to styling with Chakra UI, Tailwind CSS, and MUI. Tools like Zustand, Redux, and React Query boost state and data management. I actively explore new frameworks to stay sharp and build performant, maintainable apps

These are the essential tools I rely on for design, development, deployment, and monitoring. From collaborating in Figma, version-controlling with GitHub, to deploying on Vercel and AWS I manage the full development workflow. Monitoring tools like Sentry and Google Analytics help ensure quality and performance in production environments.

Projects
Persistence Wallet:
Developed a secure, user-centric web-based crypto wallet tailored for the Persistence One ecosystem. The wallet enables users to safely store, stake, and transfer XPRT tokens with a seamless UI/UX experience. Integrated Ledger hardware wallet support and ensured full compatibility with Cosmos-native wallets such as Keplr and Leap, contributing to broader ecosystem accessibility and trust.
https://wallet.persistence.one/Persistence Explorer:
Built a blockchain explorer frontend using Scala Play and SCSS, displaying real-time data (blocks, transactions, validators) via Cosmos-SDK and Tendermint RPCs.
https://explorer.persistence.one/ - (Deprecated)Persistence App:
Contributed to the development of Persistence DEX, a decentralized exchange enabling low-slippage swaps between XPRT (Persistence’s native token) and various assets within the Cosmos ecosystem. Focused on building seamless user interfaces, integrating Cosmos-based wallets. The DEX plays a key role in supporting DeFi liquidity on the Persistence chain.
https://app.persistence.one/pSTAKE Finance:
Developed and managed a web-based platform, enabling users to liquid-stake assets across multiple blockchains, including Bitcoin (BTC), Cosmos ecosystem tokens (ATOM, XPRT, OSMO, DYDX, STARS), and Binance Chain (BNB). Implemented secure custody integrations and partnered with top-tier audit firms to uphold high security and compliance standards across the platform and contributed to the platform’s rapid growth, helping it reach over $20M in Total Value Locked (TVL) — solidifying its position as one of the leading liquid staking solutions in the multi-chain DeFi space.
