# I resigned from my job to become a blockchain developer # Long story short I left my Software Engineer job, had no offers from other companies and had zero experience developing applications in the blockchain space. I always had a mindset of continuous improvement as the only way to become successful. Even after studying computer science for six years at the university, I decided to buy a course to learn specifically about blockchain development from the best mentors in the industry. I could understand all the concepts and technologies while searching on the internet. Still, I wanted access to experienced people and organised materials to learn from without wasting precious time. # My motivation to become a Software Engineer My passion for computers started when I was a kid when my grandfather bought me a personal computer. I was super intrigued about how it is working. Once, the PC was broken, and when the repair man came to solve the issue, I bothered him with many questions regarding each component. After that, I started being active on different forums regarding computer topics and helping people solve their problems. After a short time, I desired to build a new PC. I ordered all the components separately and built my computer. I could not explain the enthusiasm I had while assembling my PC. In the first year of high school, I almost failed the programming lecture. 😐 I hated it because none explained it in a way I could understand. But being in a situation where I almost failed, I was forced to learn it. A friend helped me with this, and the programming class I enjoyed the most in the following years at high school. I was fascinated because I was programming the computer I had just built. # My journey as a Software Engineer I started studying Computer Science in 2015 at the University Politehnica of Bucharest. In 2019, after receiving my Engineer title, I decided to continue my studies, and in 2021 I finished the Master's program in Advanced Computer Architectures. ## 🚀 My first real job, Software Engineer @ Microchip In 2018, while enrolled in the Bachelor's program, I started working at Microchip as an intern, after which I was promoted to a Software Engineer role. The position I obtained was super close to what I was searching for. During my University studies, I always showed an increased interest in lectures close to low-level development, computer architecture, and electronics. I was trying to understand how things work under the hood. At Microchip, I was very close to low-level programming. During three years of employment, I worked on projects from various fields: - web development - embedded programming - technical documentation ### Started to enjoy high-level programming After a short time, I got involved in a web application that I started from scratch with a colleague. The application was designed to help our company track data about the code we release on Github. During this project, I started using technologies that I had heard of but never used before: NodeJS, React, MongoDB, and Docker. I could quickly ramp up and start being efficient in implementing features and making good progress. ### 🔥 A dream came true: working from home I always wanted to work from home because I knew I could handle my responsibilities independently, with only an internet connection. I love having time flexibility while working from my home office. The pandemic started, and almost everyone in the IT industry worked from home. I got the feel of a fully-remote company, mainly because Microchip is a multinational company with teams spread worldwide. At this point, I knew I had the experience I needed to start freelancing and search for my contracts to work remotely for different clients. I decided to quit my daily and stable job and put all my efforts into becoming a freelancer as a blockchain developer. #### 🙏 Microchip appreciation I am very thankful that the team was a welcoming environment for recent graduates. I had the opportunity to work on various projects and was encouraged to work on the things I enjoy. In this way, I discovered what I like to do. ## 🚀 Pursuing my objective w/ the Blockchain Developer Bootcamp I have chosen Blockchain Developer Bootcamp, an online course by ConsenSys Academy, because they are well-known in the web3 space. The Bootcamp started while I was spending my last days at the job. The timing was perfect for me. The course had weekly study groups and meetings where mentors presented different subjects. When I started the blockchain course, I got in touch with a company founder from Romania willing to hire wannabe blockchain engineers like me. As part of the interview, I received a challenge to build a mini DEX using the Uniswap protocol. To get the certification, I had to submit a final project built during the Bootcamp. I decided to work on the mini DEX application as the final project. ### The mini DEX Its functionality was simple: - provide the possibility to add tokens into a liquidity pool and create the liquidity pool if it doesn't exist - remove tokens from the liquidity pool - swap tokens To easily interact with the application, I deployed two ERC20 tokens using OpenZepellin contracts. Each user can mint these tokens and start using them within the application. While working on this challenge: - I understood the Ethereum development frameworks and libraries: hardhat, waffle, TypeChain, ethers.js - I developed a smart contract in Solidity using the TDD (test-driven development) approach and deployed it to Rinkeby The repository with this application and more details can be found [here](https://github.com/filipmanole/blockchain-developer-bootcamp-final-project). ### 🔥 Finished the Bootcamp I finished the course at the beginning of December after three months of intense studying and developing my first decentralised application. I received my certification as an Ethereum developer and was ready to start using my new skills in the industry. I contacted the man who gave me the challenge to show the final result. The feedback was positive, and I received an offer from him. At the same time, I was involved in many interviews and decided to start a collaboration with Hedgehog. Their vision was to bring fractional investments of real assets for everyone through blockchain technology. ## 🚀 Got my first contract as a Software Engineer @ Hedgehog After finishing the course, Hedgehog was the first company I worked for as a contractor. I resonated with their vision and was super excited to collaborate with them. The position wasn't as close to the blockchain as I hoped because another service provided the blockchain part. Still, even if the job was not exactly what I was searching for, I was super excited about the role because: 1. I got my first contract as a freelancer, proving that my skills are valuable in the industry. 2. I was enjoying the position because I was learning A LOT. Technically I have grown a lot while working at Hedgehog. At the same time, I had the opportunity to be part of a skilful team where we shared knowledge. We were an entire engineering team of five working beside the design team on this investment web application. The progress was massive in a short time. In almost three months, we released the MVP to the initial investors. It was a success! We continuously improved the application based on feedback and added many features during the next three months. #### 🙏 I genuinely appreciate the collaboration with Hedgehog It was a place where I was encouraged to implement and show the ideas I had in such a manner that my input was considered valuable. It was great to be involved in all the pieces of the applications: backend, frontend, and even on the DevOps part, to set different deployment pipelines. During this collaboration, I also checked two objectives I was chasing: learning GraphQL and getting more knowledge about AWS. I worked extensively with some AWS services, even configuring them with Terraform. My DevOps skills improved. # 🔔 What to expect from this blog I plan to post at least one article weekly and share my knowledge about the web3 space and other software engineering topics.
