Technical Evaluation Framework: Vetting Custom Software Developers
Selecting a dedicated software development firm is a high-stakes decision that dictates your product scalability, architectural durability, and long-term operating costs. Technical leaders must evaluate agencies on engineering maturity rather than surface-level sales pitches.
1. Architectural & Engineering Competence
- ▸System Architecture & Design Patterns: Ensure candidate agencies have battle-tested experience with domain-driven design, event-driven systems, and microservices versus modular monolith trade-offs.
- ▸Code Quality & Testing Culture: Look for standard automated testing pipelines (unit, integration, and end-to-end), strict static code analysis, and test coverage thresholds (>80%).
- ▸Cloud Infrastructure & DevOps: Assess their ability to build immutable infrastructure using Terraform, automated CI/CD pipelines, container orchestration (Kubernetes/Docker), and observability stacks (Datadog, Prometheus).
