PROFILE

Vlad Kolesnikov

Worked across GoogleCloudPlatform/generative-ai, devrel-demos, and adk-docs repositories to deliver production-ready AI model deployments, agent tooling, and documentation. Developed end-to-end workflows for deploying Gemma and Qwen models on Cloud Run and GKE, integrating vLLM, Ollama, and Vertex AI for scalable inference and agent memory. Built coding and data agents using Python, JavaScript, and WebAssembly, enabling dynamic code execution and BigQuery integration. Enhanced developer experience through technical writing, deployment automation, and environment management. Addressed deployment reliability and security with OAuth 2.0, authentication middleware, and robust configuration. Contributed fixes and documentation to streamline onboarding and support multi-environment usage.

Work History

April 2026

15 Commits • 4 Features

Apr 1, 2026

April 2026 focused on delivering Gemma 4 enhancements and practical agent tooling across two repos, with strong emphasis on developer experience and data-query automation. Key outcomes include expanded Gemma 4 documentation and Gemini API access, a coding agent and web client that generate and execute Python in WebAssembly, a BigQuery data agent powered by Gemma 4, and a standalone ADK Client supporting multi-turn conversations with OAuth 2.0. Across the period, multiple fixes (PRs, UI/CSS, npm dependencies, and core logic) improved stability and usability.
