What I'm looking for

I'm open to remote work and relocation with visa sponsorship.

At APARU LLP, I integrated SignalR over secure WebSocket connections with custom reconnection logic to accelerate real-time taxi order delivery. I also redesigned features with Jetpack Compose and MVI for the ride-hailing and logistics app.

I improved responsiveness by eliminating a four-second delay when opening messages and boosted list scrolling speed by 50–70% through HTML pre-parsing. I also implemented secure SMS verification for parcel delivery completion.

I founded and launched KOLABI, an Android and iOS AI chat app built entirely with Kotlin Multiplatform. It lets users compare responses from multiple AI models in one conversation, including real-time AI Duo interactions.

At Tech Culture, I worked on DeXoo Cryptocurrency Wallet, integrating custom token support with Web3j and adding Firebase Cloud Messaging notifications. Earlier, I supported the expansion of Dylyver Technologies’ ride-sharing platform.
