Greetings! 🐱

I'm Andrey, a Staff Software Engineer who spent 12 years shipping front-end and full-stack products — and now builds AI agents and leads how engineering teams work AI-native.

My focus right now: designing agent workflows, shipping AI features into production, and helping a whole engineering org adopt AI in their daily work.

Why the 12 years matter: they're the reason the agents I build ship to production instead of staying demos.

When I'm not coding: you'll find me savoring artisanal coffee, headbanging to heavy tunes, or immersed in sci-fi and fantasy fiction.

Let's build something extraordinary together!

Short Bio

Born in a small town in southeastern Ukraine, my journey in tech began with a childhood fascination for video games and computers. This early passion set the stage for my future in programming.

Self-Taught Foundations: Driven by curiosity, I taught myself the fundamentals of programming. As my skills grew, so did my ambitions.

Career Evolution

Began as a freelancer, honing my craft and building a portfolio
Moved to Minsk to expand my horizons and accelerate my professional growth
After three enriching years, returned to Ukraine, settling in a tranquil town near Kyiv

Current Role: I'm a remote Staff Software Engineer at Toggl, where I've moved from leading front-end work to building AI agents on our AI strike team and helping the whole engineering org work AI-native.

The same curiosity that started with video games now points squarely at AI — my path has been one long thread of learning and adaptability, and right now it's all about building with agents.

Work Experience

Early Career: Drupal Specialist

Started as a freelancer, then transitioned to full-time development
Gained deep knowledge of Drupal's internals
Contributed custom modules to the Drupal community, demonstrating commitment to open-source

Transition to Front-End Development

Pivoted to focus primarily on front-end technologies
Leveraged innate curiosity to expand skill set across various platforms and frameworks
Gained diverse experience in telecommunications and fintech industries
Developed web, desktop, and mobile applications of varying complexity

Current Focus: AI Engineering

Building AI agents and agentic workflows on Toggl's AI strike team
Contributing to in-product AI features — an in-app assistant that answers questions over your report data, with source citations
Leading AI-native engineering practices: agentic coding tools, a shared internal skills library, guild talks, and live demos
Building internal AI tooling — a Claude-powered Slack agent that answers questions over private repos
Sharing what I learn publicly through The Gray Cat (@thegraytcat)

From Drupal specialist to front-end lead to AI engineer, every step has added a layer — deep technical range, a product-minded eye, and now the judgment to build AI that actually ships. That combination is what I bring to the agents and tools I build today.
