PROFILE
Detail-oriented Back-End Engineer specializing in the Node.js ecosystem
(NestJS, TypeScript). Experienced in designing microservices architectures,

EXPERIENCE
Back-End Engineer | June 2025 – Present
Microservices Architecture: Engineered and maintained scalable
backend services using NestJS and TypeScript. Designed robust inter-
service communication using gRPC and RabbitMQ, ensuring reliable
data flow across distributed systems.
Testing & Quality Assurance: Established a strict integration testing
architecture using Jest. Implemented deterministic test bootstraps
with real PostgreSQL databases and Prisma, handling schema
migrations, truncations, and concurrency locks to ensure complete
test isolation and reliability.
Database Management: Designed relational database schemas and
managed complex migrations using Prisma ORM. Implemented
advanced transactional patterns, including the Outbox pattern, to
guarantee data consistency.
Infrastructure & CI/CD: Participated in the deployment lifecycle.
Worked with declarative CI/CD pipelines (Checkout, Build Docker
images, Push, and Deploy to Kubernetes clusters). Configured
application environments for internal and cross-namespace K8s
networking.
API & Security: Developed secure authentication and authorization
flows (OAuth2, JWT, local/session storage). Refactored domain layers to
centralize visibility logic and eliminate code duplication.
