Full Stack Engineer and Blockchain Engineer
Colombo, Sri LankaOpen to flexible roles
Hey, I'm Nimsara, a full stack & blockchain engineer from Sri Lanka and a final-year IT undergrad at University of Moratuwa. At Ceylon Cash I built back-end systems for CeyPay, its crypto payment platform, and grew into business development for it. I love shipping Web3 products, Telegram bots used by 40,000+ people, and clean, fast web apps where the small details matter, and I automate almost everything else with n8n. Right now I'm doing research, freelance work and building a startup, and I'm open to flexible roles until I graduate.

Savings layer on Arbitrum for people paid in USDC. Every payment auto-splits into spend and keep, savings sit in a personal cooldown vault, and you can borrow an advance against them. Passkey wallets, no seed phrase. Built for the Arbitrum Open House Buildathon and Colosseum Crypto World's Fair.

Instead of asking for sponsorship to get to Devcon Mumbai, I'm renting out my suitcase. A 3D suitcase drawn entirely in code that you can spin, 18 ad spots you buy with USDC across six networks (paid straight to my wallet, verified on-chain), and a combination lock hiding a discount.
