Projects I worked on

Web/Mobile App

A revolutionary app designed to be a secure repository for your knowledge and memories. hrtg.me ensures that your valuable insights are accessible to future generations, no matter where they are in the world. The product will be a simple, intuitive, and user-friendly app that allows you to record your thoughts, experiences, and memories in a secure and private environment. As the co-founder and sole developer of hrtg.me, I am responsible for every aspect of the platform’s creation and product development. I want to use my experience and expertise in blockchain and web3 technologies to build a product that is fun and build it for the long term. We are still ways to go before our product is ready for production, but our vision is clear.

Decentralized App

Headquarters (HQ.xyz) is the onchain business account, unifying financial operations in today’s onchain economy. Token payments, fiat ramps, and reporting in one unified dashboard. I worked closely with the design team to implement the UI/UX design. During my time at HQ.xyz, I enhanced the application's functionality and user experience by integrating multiple Web3 wallet providers for sign-in, Gnosis Safe's batch execution features for streamlined transactions, and the CowSwap widget for seamless token swaps. Additionally, I assisted in migrating accounting platform providers, ensuring smooth integration with Xero and QuickBooks.

Corporate Website

Bake is a platform that provides the most transparent way to get cashflow from your cryptocurrencies. There are multiple products that bake offers, such as staking, lending, and borrowing of cryptocurrencies. I worked together with another team member to completely revamp and redesign the corporate website in a short span of 1 month. We collaborated with the design team to introduce new products, services, and rebranding.

Decentralized Exchange

Maverick Protocol as a Liquidity Operating System for decentralized finance (DeFi), aims to provide a one-stop liquidity solutions for token projects. I developed customer-focused features and integrated APIs into the DApp while collaborating with other DeFi protocols. To enhance blockchain monitoring and smart contract debugging, I introduced Tenderly as an addition to our existing monitoring tools. Additionally, I leveraged various blockchain tools, including Nansen, Breadcrumbs, interface.fyi, and block explorers, to assist users with their on-chain transactions through Discord support tickets.

Web3 Smart Contracts

Weather Index Insurance protects the agriculture businesses and individual farmers against uncertain weather conditions. Claims are triggered automatically based on specific weather indices such as rainfall level, temperature, wind speed or other measurable weather-related events. Leveraging the factory design pattern, I developed a suite of smart contracts that fully automates the insurance lifecycle, from policy registration to claims processing. To enhance security and reliability, I utilized OpenZeppelin libraries, integrated Chainlink oracles to fetch weather data, and implemented verifiable merkle roots for efficient on-chain storage of sensitive user data.
