Hi, Pleased to meet you. I am
Gowtham.

I’m a passionate Blockchain Developer 👨💻 at Santa Browser. I love upskilling myself in Smart Contract Development 📝 and other web3 technologies. I've 4+ years of professional experience in Full Stack Software Development.
About Me
Hello! I am Gowtham 🙂 and I enjoy creating products on blockchain ₿ and Internet 🌐. My interest in programming started back in 2015 when I first completed my C and Java Beginner Course.
Then in college (2016) I had the privilege to work as Student Researcher 👨🏽🔬 and also as Robotics Club Member, where my programming journey kick-started. Fast-forward to today, and I’ve gained vast experience by contributing to many projects in different domains.
Currently, I am working on web3 wallet development at my current role.
Here are a few technologies I’ve been working with recently:
- Solidity
- Ethers.js
- JavaScript (ES6+)
- React
- Typescript
- HTML/CSS

Featured Project
Gasless NFT Marketplace
A gasless marketplace 🛒, where sellers can list the NFT for sale against a specified no of ERC-20 token called GEM's 💰 and whitelist some buyers.
So the whitelisted buyers will be able to transfer the required GEM's 💰 and buy's the NFT. And user's can burn their ERC-721 token to upgrade to ERC-1155 token.
Furthermore, gasless ⛽ transaction is also implemented using ERC-2771. The relay is created using NodeJS, and it also tracks the amount of gas spend in a database for analytics.

Open Source Contribution
Solidity by Example is an open source project that helps many programmers to learn 📙 basics and intermediate level solidity programming. I personally learnt from it. I created a PR for using Commit Reveal Scheme to Front Running Hack 🐱💻 and it got approved and went live. Working on other improvements in this website.

Featured Project
Todo Dapp on Polygon
ToDo is a decentralized task ✍️ management app with on-chain NFT membership and governance. To access the application, we need to connect Polygon Mainnet using our Metamask wallet. The user should mint an ERC-721 NFT as membership 🎟️. The first 1000 NFTs are free, after that 0.001 ether is charged. The ToDo app is run by the community 👩💻👨💻 with the help of DAO. The governance is established via ERC-20 token, Time lock and Open Zeppelin Governor contract.
