Crypto asset trading platform
Backend systems for trading. I work on the data layer, the internal tools around it, the frontend connections, and the performance work that keeps the platform steady when volume goes up.

a bit about me
I am a full stack developer in Istanbul. I work on a live cryptocurrency exchange at TRA Tech, and most of my day is on the backend. A lot of that work is moving .NET services from old versions up to the newest ones, and keeping the data layer fast enough that nobody has to think about it.
On the frontend I turn designs into working code, keep those projects current, and use the newest tools. A large part of the job is security: integrations and user flows that follow the rules regulators set. Third party integrations are another area I have experience in: bank connections, mail and SMS services, and liquidity providers.
Next to all of this I build my own side projects. Answhere, an iOS app, is the one that shipped, and I will keep building for mobile.

I wrote and ran manual test cases for several products. I read the results, reported the bugs I found, and ran regression cycles. I worked closely with the developers who fixed them.
selected work
Answhere / Sezgi
A calm iOS app built around one simple action. You hold a question in your mind, press and hold, and read a short reflection. Everything stays on the device. Fifteen languages, no account, no tracking.
TRCrypto.Net
BtcTurk and Binance TR clients built on CryptoExchange.Net. I am working on REST and WebSocket access, one shared API surface across both exchanges, input validation, and unit and integration tests.
SecurVault
Custody infrastructure that keeps the private keys of Web3 projects and autonomous AI agents inside a signing engine with no connection to the internet. API calls are charged per request through the x402 protocol.
