Backend

I build solid, secure and scalable backends to support product growth. My approach covers API design, data modeling, security and production operations. Three years of hands-on experience across both startup and large public-sector organization contexts.

Core technologies

Runtime & frameworks

Node.js, NestJS, Express (TypeScript-first by default)

Databases

PostgreSQL, MariaDB, MongoDB, Redis · TypeORM, Prisma

APIs & integrations

REST, Swagger/OpenAPI, JWT auth, OAuth2, webhooks

What I deliver

  • Documented and versioned business APIs: clear contracts for frontend, mobile and third-party consumers.
  • Clean and evolvable data models: normalized schemas, managed migrations, no hidden technical debt.
  • Authentication & security: JWT, OAuth2, role and permission management, OWASP protections.
  • Error handling, logs and monitoring: application traces, structured log levels, production alerting.
  • Interoperable services: backends easily consumed by web, mobile and data pipelines.

Applied principles

  • Layer separation: controllers, services, repositories, each with a single responsibility.
  • Strict input validation: typed DTOs, boundary validation, no implicit trust.
  • Performance: optimized queries, indexing planned from design, caching adapted to context.
  • Testability: dependency injection, decoupled services, unit and integration tests.
