Full-stack engineer. Hands-on tech lead.
I'm Anton Kovalenko, also known as Anthy, a full-stack engineer with 6+ years across web applications, browser games and AI products. My work spans Vue and React interfaces, Node.js services and technical leadership. AI tools are part of my daily workflow, helping automate routine tasks and deliver features faster while maintaining code quality.
At Gen2B, the progression from senior engineer to tech lead brought responsibility for architecture, delivery and mentoring alongside daily coding. That work included a major frontend overhaul and three generations of the UI kit, evolving from Vue to Lit. Two developers grew into senior roles under my mentorship.
My open-source projects include Ravenpass, a Go and TypeScript password manager built around a user-controlled encrypted vault; prox, a Go reverse proxy used in production for streaming and large transfers; Grambot, a TypeScript framework for Telegram bots; and Atlas, an AI assistant for desktop apps. Together, they connect my work in application interfaces with the services and tools behind them.
Based in Almaty, I'm open to frontend, backend and full-stack roles, technical leadership and contract work, remotely or with relocation. Previous experience includes working with teams in the US, Kazakhstan, Armenia, Cyprus and the UAE. Russian is my native language, with English at B2 level.
Projects
An open-source password manager for macOS and Android. Passwords, passkeys, two-factor codes, and private data live in an encrypted vault file that users keep locally or in a cloud folder of their choice. Built with a Go core and React UI.
