Senior Backend Engineer — Clojure · PostgreSQL · Kafka · LLM in production.
13 years in software, the last seven building the supplier platform at Kasta — a major Ukrainian marketplace: feed ingestion (95% of new catalog intake), regulated merchant onboarding, LLM product moderation. Multi-TB PostgreSQL, tables up to 2.7B rows.
That work lives in private repositories — what's public here is older personal projects and experiments.
