David

Lead / Tech Lead Backend Developer with 18+ years of experience building and evolving web applications in production environments. I specialize in designing clean, scalable, and maintainable backend systems, with a strong focus on architecture, long-term impact, and team efficiency.

I apply Web-Oriented Architecture principles pragmatically, choosing the right patterns according to business and technical constraints (RESTful APIs, Clean & Hexagonal Architecture, CQRS, DDD). My goal is always the same: reduce complexity, control technical debt, and enable teams to move fast with confidence.

I’m highly comfortable with JavaScript / TypeScript across the stack. On the backend, I mainly work with NestJS, and on the frontend with React (MERN stack).

As a Tech Lead, I take ownership beyond code: defining best practices, mentoring developers, driving architectural decisions, and continuously improving code quality and delivery pipelines.
