SCROLL TO EXPLORE
WEB3 / FREELANCE
Fiduwork
Senior Frontend Engineer (Contract) • 07/2025 - present
- Architected production payment system from zero, integrating Stripe (Web2) and on-chain escrow smart contracts (Web3).
- Built wallet connection infrastructure using RainbowKit and wagmi v2, supporting MetaMask, WalletConnect, and Coinbase Wallet with seamless multi-chain switching across Ethereum, Base, and Polygon networks.
- Developed gas-optimized smart contract interaction layer using ethers.js and wagmi with transaction batching and efficient contract call patterns to minimize on-chain operations and reduce user transaction costs.
- Implemented comprehensive error handling and recovery flows for wallet rejections, network failures, and transaction timeouts, maintaining low support volume through intelligent retry logic and clear user status messaging.
- Created reusable React component library with modular Web3-specific components covering wallet connection, token approvals, transaction signing, and network detection, enabling rapid feature development and consistent UX patterns.
- Designed DAO-based dispute resolution interface with token-weighted voting, automated arbitration workflows, and community reward distribution for client-freelancer conflicts.
- Optimized payment completion funnel through real-time gas estimation, predictive fee modeling, and batch transaction capabilities, achieving minimal transaction abandonment and high user conversion.
- Contributed to smart contract integration and escrow workflow design, delivering transparent trust-minimized transactions with automated fund release, milestone tracking, and dispute escalation mechanisms.
WEB3 / DEFI
MahaDAO
Senior Software Engineer • 02/2024 - 05/2025
- Architected and delivered responsive Web3 interfaces using React, TypeScript, and Tailwind CSS for DeFi protocols, owning the entire frontend architecture and establishing coding standards across the engineering team.
- Led integration of ODOS swap routing with custom liquidity visualization engine, enabling users to discover 12-15% better pricing across aggregated DEX routes while reducing swap failure rates through intelligent slippage and deadline management.
- Designed and implemented ERC-4626 vault management system covering deposits, withdrawals, yield analytics, and Merkle-based reward distributions, handling complex vault strategies and multi-token accounting.
- Spearheaded migration to Next.js 14+ with App Router and React Server Components, reducing client-side JavaScript by 40% and page load times by 35%, establishing new architectural patterns adopted across all protocol frontends.
- Built end-to-end Solana dApp integration for Raydium CLMM, architecting Phantom wallet connection, Anchor program interactions, and real-time pool state synchronization, enabling the protocol's first multi-chain expansion.
- Pioneered ERC-4337 account abstraction implementation with custom paymaster integration, eliminating gas barriers for new users and establishing reusable smart account patterns for future protocol features.
- Owned cross-chain infrastructure between Base and Solana using LayerZero SDK, architecting bridge monitoring, transaction recovery mechanisms, and user status tracking.
- Established multi-chain deployment framework across Ethereum, Linea, zkSync, Optimism, and Manta, creating automated testing pipelines and deployment workflows that reduced release cycles timelines.
FINTECH / SCALING
Ryze
Software Engineer • 04/2022 - 01/2024
- Built core DeFi platform frontend modules covering pricing engines, liquidity management, exposure tracking, and portfolio monitoring, handling complex financial calculations and real-time multi-asset position updates.
- Designed end-to-end transaction flows for minting, burning, and collateralization with comprehensive error handling, status tracking, and confirmation patterns, achieving 95% successful transaction completion rates through careful UX design.
- Developed real-time interactive charting system with market trend dashboards using data visualization libraries, enabling users to analyze risk/reward metrics and make informed decisions across volatile DeFi market conditions.
- Optimized frontend performance through systematic code splitting, lazy loading, and route-level bundling, reducing page load times by 30% and improving Time to Interactive metrics across mobile and desktop platforms.
- Delivered mobile-first responsive interfaces using React, TypeScript, and Tailwind CSS with continuous UX improvements driven by user behavior analysis, increasing engagement by 25% and reducing bounce rate by 20%.
- Implemented in-house automation tools and smart assistance features reducing support requests by 25%, while maintaining scalable MERN architecture supporting rapid feature delivery across the platform.
BLOCKCHAIN / SOLUTIONS
Deqode
Frontend Engineer • 01/2020 - 03/2022
- Architected and deployed Web3 frontends integrating Ethers.js, The Graph, and EIP-712 signature support, enabling gasless transactions and seamless wallet connectivity to improve accessibility for end-users.
- Built protocol vesting UIs backed by OpenZeppelin proxy contracts and developed interfaces for complex DeFi features including derivatives-based AMMs and perpetual futures trading systems.
- Revamped a fintech dApp v2 using Next.js (SSG/SSR), React Query (TanStack Query), and Apollo GraphQL, boosting page load speeds by 70% via Vercel CDN integration and static asset caching.
- Designed custom blockchain UI architectures to visualize transaction security and data flows, improving reliability perception by 30% and contributing to a 25% increase in user engagement across client-facing projects.
