BelarusWhat I'm looking for
Senior Java backend engineer with 15+ years of commercial experience building distributed, event-driven systems end to end, from architecture to production support.
Recent work: a multi-tenant mobility SaaS for the Nordic market (Java 21, Spring Boot 3, ~40 Maven modules, AWS ECS): rule-based pricing engine, PostgreSQL read/write splitting, Transactional Outbox with Kafka, idempotent consumers and DLQ, Elasticsearch search with near-real-time indexing, integrations with Adyen, Fortnox/Billogram, Twilio, EV chargers and smart locks. Earlier: bank loyalty platform (Kafka, PostgreSQL), enterprise MarTech/PIM systems (Oracle, MS SQL), Elasticsearch-based knowledge platform.
I also run Foundevs, a small software company, and built my own SaaS (Telegram Mini App with LLM-generated training programs and subscription billing), so I'm comfortable owning a product end to end. I use Claude Code daily for AI-assisted development.
Looking for a fully remote senior Java backend role; B2B contract via my Polish sole proprietorship, invoicing in EUR/USD or USDT. English B2, Polish B1.
