About
Hi, I'm Alexey
I'm a senior software engineer in Munich. I build web apps, microservices, and the cloud infrastructure they run on, across IoT, fintech, and public-sector systems.
I like owning things end to end and working on small teams where I get to touch everything.
I work mostly in TypeScript, Go, and Python these days, with deep roots in Java and Kotlin, and I lean on AI-assisted development to move faster. But technologies and tools are just instruments. What they're really for is building something for people that lights up their day - the way an aurora lights up the dark.
Experience
A short history
-
2025 - Present
Lead Software Developer · Sono Solar, Munich
Leading engineering for the platform that manages fleets of vehicle-mounted solar installations. Shipped the React installer tool for field engineers to production, added support for new telematics devices, and reworked the data pipeline. Owned CI/CD and deployments end to end, introduced a new authentication mechanism, migrated the company's infrastructure to code on GCP, and provisioned a full white-label clone of the platform via Terraform.

2018 - 2025
Senior Software Engineer · tado°, Munich
Took a new product generation from hardware prototype to install-ready in under a year, working on top of unfinished Matter protocol specs. Designed and ran an OAuth 2.0 authentication server, built integrations with Alexa, Google Home, and IFTTT, and shipped the tado° Professional installer app in Flutter. Acted as a technical anchor across the org - regular workshops, demos, and self-serve analytics tooling for non-engineers.

Team Lead / Software Developer · Lanit, Moscow
