I'm a software developer with almost 2 years experience. With only having a front-end knowledge during my first day, I was challenged to quickly adapt to full-stack and I successfully did it with my eagerness to learn and improve. I continued to work on being full-stack until I was moved to a blockchain-related project which is I was completely unfamiliar. I learned quickly and built my confidence day-by-day through our projects. I also once experienced creating a smart contract from scratch using Solidity. I kept working on blockchain projects until I was assigned to a leadership role which I really want be in. The role was tough but it is what I really seek because the tougher the work, the more my confidence grew. It was pressuring and doubts are coming since blame will be on me if we fail to meet the goal but I'm ready to take all the burden and the blame because it is my responsibility to lead them and achieved our goal. We failed sometimes but I just get something that I could learn from it and moved on. My duty from it was short lived but I learned a lot from it and grew a lot professionally and personally.Despite having less than 2 years of experience, I've already experienced the tough challenges on being in a tech industry. I had several ups and downs but it made realize that I can handle any situations if I'm eager to overcome it, no matter how much I fail. I never thought that from a former student with an underachieving grades would highly believe that he can overcome any obstacles that he is going to face. Changing myself from believing that I'm mediocre at best to believing that I'm capable of something greater was for me, the greatest accomplishment that I made. Changing my mindset into a positive and optimistic one is life-changing.
