With almost 2 years of experience in blockchain development, my expertise lies in both smart contract development and security audits. I am well-versed in several ERC standards, DeFi and layer 2 protocols, and NFT projects. Additionally, I have experience with EVM opcodes and low-level assembly. My experience also includes developing decentralized applications such as NFT marketplaces and decentralized exchanges, using NextJS and React as front-end frameworks.
I am currently working as a freelancer for Sentnl.io as a Solidity Security Auditor and at Fractio Inc. as a Solidity Security Engineer, where I am responsible for ensuring the security and integrity of smart contracts through conducting security audits and providing recommendations for improvements. I have also gained expertise in identifying and addressing security vulnerabilities and gas optimizations through participating in smart contract bug bounty contests on platforms such as Code4rena and Sherlock. Additionally, I have a background in writing technical articles on the Ethereum blockchain, including Solidity wargames solutions and gas optimizations and I find myself currently developing a fully on-chain implementation of a board game, to be deployed in the near future.

My journey to become a Blockchain Engineer has been very eventful. I started working under 99x Technology( a leading software services provider based in Sri Lanka, Norway and Sydney) for a start-up named Tracified (a supply chain traceability application which utilized the blockchain technology through agnostic means to provide trust through traceability), as a blockchain developer as part of their research team. While, being a part of the team i published a research paper on a "Blockchain Based Knowledge Sharing and Organising Platform" which focused on monetizing knowledge while making it a collective approach. Furthermore, I have developed an event registration and verification platform that tokenized Tickets as Stellar Assets and proved ownership of ticket. Following this, i have worked on ICO releases on a freelance basis for Exip Token, and few other classified companies. Most most recent success would be securing the third place at the long hash global hackathon during the pandemic for building a blockchain based crowd funding application called HumanFund. Finally, as to why i would be a great fit for this job, would be because of my ability to adapt and change at alarming velocity proven by my change in field from being a Bio, Chem, Phy student to being a Graduate in Computer Science and further being able to grasp blockchain and being able to use any language or service with just a brief stroll through their documentations makes me perfect to be the one who can make a difference. My background in research and development is a major boost to my ability to grow on my own. To address the elephant in the room, i am very well equipped and have trained myself to follow a CI/CD scrum project development method along with the help of AWS stacks, MERN stack and GoLang as a personal favorite.
