Mir Safwat
Ayser.
I ship production systems that are fast, reliable, and a little obsessive about craft — from React interfaces to Ethereum smart contracts.

02About
Engineer first. Designer of the details that make software feel inevitable.
I'm a full-stack engineer based in Toronto with five years shipping software across fintech, cybersecurity, healthcare, and real estate — domains where reliability is not a nice-to-have.
At Paytrie I work end-to-end: TypeScript and React on the client, Fastify and Postgres on the server, Grafana when things get loud, and Solidity when money actually has to move on-chain.
