At a Series-A HealthTech startup, I'm building the MVP backend for an elderly-care monitoring platform. I designed telemetry ingestion from remote devices over MQTT and Apache Kafka, using a transactional outbox for event delivery.
I implemented type-safe persistence with PostgreSQL and jOOQ, and deployed the services on Kubernetes. Integration tests use Testcontainers with real PostgreSQL and Kafka instances.
At Credit Registry, I developed a credit-scoring web service and reusable scoring library for microfinance institutions using Java, Spring, and Hibernate. I also designed and maintained integrations with external data providers.
At Sberbank, I developed big-data processing pipelines with Scala, Spark, and Hadoop, and built data marts and a CLI tool for an internal Airflow-like scheduler. I bring backend experience across fintech, data processing, and remote monitoring products.
