Russian FederationWhat I'm looking for
Senior full-stack engineer with 25 years in production software — from microcontroller firmware to multi-tenant cloud platforms and mobile apps.
I do best on mature, business-critical products: getting into an unfamiliar codebase fast, modernizing the platform beneath it, and growing it without disrupting users. Typical work spans Django/Python SaaS, PostgreSQL, Android clients, and C++ systems tooling; I go deeper into Embedded Linux when the product needs it.
Recent focus: long-running agricultural SaaS (features, security, Python 2→3, multi-tenant upgrades) and a from-scratch filesystem recovery engine, plus an independent Yocto/A-B OTA board bring-up.
