Behind the Byte: How a Crypto Bull Run Sparked This Developer's Career Shift Into Blockchain

Whether integrating emerging technologies or developing protocols that enhance transaction efficiency and security, I aim to ensure Revinfotech remains at the forefront of blockchain innovation.

Last week, we kicked off our new column “Behind the Byte” on Newzchain, aiming to shine a spotlight on people who build and shape technology. This includes blockchain developers, software developers, data scientists, AI specialists, machine learning experts, and more. 

This week, we're featuring Atul Agrawal, a Senior Blockchain Developer at RevInfotech. Agrawal gave us a peek into his experience and shared some great insights from his career. 

Read on to learn more about his journey in the exciting world of blockchain.

Agrawal's Blockchain Breakthrough

Atul Agrawal's dive into the Web3 world started back in college when he first saw the potential of blockchain technology. At the time, his interest was just budding, sparked by the early buzz around cryptocurrencies. 

He started his career at Tata Consultancy Services (TCS) as a Database Administrator, focusing on traditional tech. However, the crypto bull run reignited Agrawal’s interest in blockchain.

“I was really driven to dig deeper into Web3. I dedicated myself to understanding blockchain technology, getting the hang of smart contracts, and grasping how decentralized apps could change things,” said Agrawal. “The more I learned, the more I realized how much potential there was for blockchain to really shake things up across different industries.”

And this renewed passion and growing expertise prompted a pivotal career transition for Agrawal. He decided to pivot fully into blockchain development, where he could leverage his skills and interests to contribute to various aspects of blockchain and beyond. 

It wouldn’t be wrong to say that Agrawal’s transition from a mere industry observer to a committed blockchain developer is fueled by the blend of both — personal investment interest and curiosity towards the sought-after technology. 

Beyond Basic Coding

At Revinfotech, Agrawal’s role as a Senior Blockchain Developer encapsulates a broad range of responsibilities that stretch beyond coding. His primary duties involve not only the development and optimization of smart contracts but also the strategic planning and architectural design of new blockchain solutions.

He also actively participates in the initial stages of project development, where he assesses new requirements and helps define the scope of work. This process often requires meticulous research and the creation of innovative system architectures tailored to the specific needs of the project. 

“Whether it's integrating emerging technologies or developing protocols that enhance transaction efficiency and security, my goal is to ensure that Revinfotech remains at the forefront of blockchain innovation,” Agrawal added. “This proactive involvement not only drives the company’s technological advancement but also reinforces our position in the market as leaders in the blockchain industry.”

To learn more about his work and experience, and bring the nitty gritty details, we dug deeper and asked about some of the projects he has worked on or currently working on. 

“One of the most significant projects I've been involved with is a renowned Layer 2 blockchain solution designed to enhance scalability and reduce transaction costs. This project allowed me to dive deep into smart contract optimization and state synchronization across blockchain layers, addressing some of the most pressing issues in blockchain technology today,” said Agrawal.

Additionally, Agrawal spearheaded the development of a novel NFT standard and the subsequent launch of a highly successful NFT collection. According to him, this project not only challenged his technical skills but also provided a rewarding experience as it achieved a sell-out worth millions of dollars within minutes.

Language Lineup for Blockchain

Furthermore, we also chatted about programming languages that he uses in his day-to-day tasks. To which, Agrawal stated that he mostly works with Solidity, JavaScript, Node.js, and Rust in blockchain development.

He also gave reasons why he works with these particular languages, saying:

“Solidity is a must for writing smart contracts on Ethereum and similar platforms, so it's a big part of what I use. JavaScript and Node.js are key for building the front-end and back-end of blockchain apps, making sure everything runs smoothly for users. Rust is great for its performance and safety, which is super important when you're working on secure blockchain systems. It helps avoid common bugs that can lead to serious problems in blockchain environments.” 

Not to mention, the RevInfotech developer is now learning Go. He believes it's straightforward to manage multiple tasks at once and is becoming more popular in blockchain, especially with new technologies like Ethereum 2.0, an upgrade to the Ethereum blockchain.

Legit Words for the Aspirants

For anyone eager to break into the world of blockchain development, Agrawal has some solid advice. He emphasizes a balanced approach that builds on a strong computer science foundation while also diving deep into specialized blockchain skills. 

First and foremost, Agrawal recommends bolstering the core programming skills. He believes a strong grasp of object-oriented programming and languages like JavaScript is crucial. For blockchain-specific tasks, particularly smart contract development, proficiency in Solidity is essential. Next, one should understand how blockchains work, including concepts like the Ethereum Virtual Machine (EVM), consensus mechanisms, and the importance of decentralization. 

Agrawal also stresses the importance of getting comfortable with development tools.  

“Familiarize yourself with Hardhat, Truffle, or Foundry for deploying smart contracts, and don't overlook security tools like Mythril and Slither for auditing," he said. “These tools are vital for any developer looking to make a mark in the blockchain space.”

Knowledge of smart contract standards is crucial for any blockchain developer. He also stresses the fact that it is important to be well-versed in ERC standards, as these set the framework for implementing various types of tokens within the Ethereum ecosystem.

“Ultimately, nothing beats hands-on experience,” Atul points out. 

Furthermore, he recommends building projects or contributing to open-source projects to gain practical experience. He believes in having a portfolio of deployed projects that showcase skills.

Lastly, Agrawal encourages aspiring developers to keep up with the rapidly evolving blockchain technology. He emphasized the importance of staying current with the latest trends and tools and being open to learning new languages and frameworks as the industry evolves.
