David Suarez

Backend Software Engineer

Designing backend systems, APIs, and data workflows with clean architecture and domain-driven design.


Core Stack

  • Languages: TypeScript, Javascript, Python, Java.
  • Frameworks & Protocols: NestJS, Express, Apollo GraphQL, REST.
  • Databases & Queues: PostgreSQL, Redis, BullMQ, TypeORM, Prisma.
  • Tooling & Infrastructure: Docker, Docker Compose, Linux, Git, Jest.

Engineering Approach

  • Domain-Driven Design: Keeping core business logic isolated from frameworks, databases, and external delivery mechanisms.
  • Clean Architecture: Structuring systems into decoupled, testable layers with strict dependency flow.
  • Event-Driven Architecture: Using asynchronous queues and event streams (Redis, BullMQ) to separate background jobs from request-response cycles.
  • Testing: Verifying system behavior through comprehensive unit, integration, and contract tests before shipping to production.

Philosophy

  • KISS (Keep It Simple): Designing with the minimum architectural complexity required to solve the actual technical problem.
  • YAGNI (You Aren't Gonna Need It): Resisting speculative abstractions, premature patterns, and unneeded infrastructure layers.
  • DRY (Don't Repeat Yourself): Ensuring single sources of truth for business logic without sacrificing module decoupling.
  • Open Source: Prioritizing open standards, standard libraries, and community-driven tooling.
