Blockchain Engineering Intern
A general introduction to blockchain, DeFi, and cryptocurrency. Full-stack Ethereum development and blockchain research.
- ▸Full-stack Ethereum development — smart contracts through to frontend
- ▸Explored blockchain fundamentals, DeFi protocols, and cryptocurrency
- ▸Built and tested Solidity smart contracts with Hardhat
- ▸Conducted blockchain research alongside the engineering team
Context
Securrency is a fintech company in Abu Dhabi focused on blockchain-based solutions for institutional finance. I spent a couple months there the summer after my first year of university.
What I Did
This was essentially my introduction to the blockchain world. I got exposure to the full spectrum — from the theoretical foundations of decentralized systems to hands-on Ethereum development.
Day-to-day work involved:
- Writing and testing Solidity smart contracts using Hardhat
- Building Node.js/TypeScript services that interact with deployed contracts
- Learning about DeFi protocols, tokenization, and how crypto actually works under the hood
- Doing some blockchain research alongside the engineering team
What I Learned
This was an early internship, and it was mostly about exposure. The biggest takeaway was understanding how blockchain development differs from traditional software — the immutability of deployed contracts means you think about bugs and edge cases very differently when you can't just push a hotfix.
It was also my first time working in a professional engineering environment, which set the baseline for what I expected from future roles.
