ANNA DOBROVOLSKA
I'll be replacing AI soon.

Until then, I build backend systems with TypeScript/Node.js — distributed
workflows, event-driven architecture, APIs, PostgreSQL, Kafka, AWS. This is my
deepest production stack, not a boundary; throughout my career, I’ve quickly learned
new technologies and domains and applied them to production systems.

GraphQL scalar validations
- Actively unblocked delivery by splitting and detailing tasks, managing cross-team
dependencies, and resolving blockers;
