Blockchain Engineer

I have over a decade of experience in designing and developing applications, including my work in blockchain technology and web3.

In my most recent role as a Freelance Software Engineer, I developed an NFT-powered MetaFarming platform for Greens.id, funded by East Ventures, using Next.js, Feathers.js, and MongoDB. I have a deep understanding of web technologies and a keen eye for UX/UI design, which I believe are essential for creating engaging and user-friendly experiences.

I also have previous employment experience in a remote global web3 startup called Saakuru Labs where our team members are spread across 19 different countries. There, I setup and managed various blockchain nodes, added new feature to Blockscout Blockchain Explorer, and developed the backend system of Saakuru Web3 Wallet App using Java and MongoDB, implemented Risk Score API for scam and fraud detection using node.js and Puppeteer. I have also worked at an IT Solution company called Inergi where I developed backend solutions for large corporation application using Kotlin and Springboot Framework, which includes Fiduciary Management System, eCommerce Aggregator System, Video Analytics App, Knowledge Management System and Integrated Software Solutions (Display, Customer Feedback, Head Office, Kiosk).

Not only that, I've also participated at Solidity Mastery Bootcamp by Eat The Blocks learning not only the fundamentals of Solidity but also many advanced topics like Solidity Advanced Patterns, Smart Contract Security (incl. How to Hack Smart Contracts), Yul & Gas Optimization, Testing and Deployment with Foundry, Smart Contract Interactions and Smart Contract Professional Development Process. I also got to implement what I learned during the bootcamp by developing my own Web3 Game (https://2048.jasonyapri.com) for my personal portfolio running on Optimism Sepolia Testnet, and undergoing the workflow of professional Solidity Engineer; Development ➜ Testing ➜ Gas Optimization ➜ Security Check ➜ Deployment. Furthermore, I have also completed several certifications, including the Certified Cardano Developer Associate, demonstrating my commitment to continuous learning and professional development in the blockchain field.
