I'm Oleksandr Tkach. .
User interfaces that I had a hand in developing.
Aave Governance V3
The official governance interface for the Aave protocol. Built high-performance voting and delegation mechanisms with direct RPC optimization.
Aave Analytics Dashboard
Comprehensive analytics dashboard for Aave protocol data. Visualizing complex financial data and protocol health in real-time.
From UI Components to Multi-Chain Architecture.
My journey in web3 development started with the early days of the Aave Protocol, where I was mainly responsible for the App UI transformation across V1, V2, and V3. Later, at BGD Labs, I focused mostly on governance interfaces for the Aave ecosystem and optimizing direct RPC interactions to save costs and improve speed. This experience led me to create TUWA. Building these tools helped me evolve from just writing code to understanding the full architecture of a product.
