Hi there 👋 I'm Maria

Senior Backend Engineer with 9+ years building systems that survive production. I've maintained 99.999% uptime on real-time, high-concurrency platforms processing critical transactions.

Languages change. Distributed systems don't.

🎯 Current focus

Deepening Go for cloud-native, event-driven backend systems: concurrency, transactional consistency, idempotency, PostgreSQL, Kafka, Kubernetes and observability.

⚙️ Core stack

Backend: Python · FastAPI · Node.js · TypeScript · NestJS · Go (currently deepening)
Data: PostgreSQL · Redis · Kafka · RabbitMQ
Cloud: AWS (ECS, RDS, S3, Lambda) · Docker · CI/CD
Quality: TDD · DDD · OpenTelemetry · observability · transactional consistency
