Diego Bergua

Senior Frontend Developer and Technical Lead

I build scalable frontend products with strong technical direction.

I am a frontend specialist based in Zaragoza with 15+ years of experience leading delivery, architecture and interface implementation.

I help product teams ship performant, maintainable web applications with clear UX, pragmatic architecture and hands-on engineering leadership, while also working on generative AI initiatives, agent-based workflows and AI-assisted software delivery.

My core work sits at the intersection of frontend engineering, architecture and delivery: defining maintainable foundations, guiding teams through implementation and keeping performance, usability and quality visible from discovery to production.

More recently, that work has expanded into generative AI and agent-based engineering: designing practical ways for teams to use custom agents, AI-ready repository conventions and AI-assisted workflows without losing engineering control.

Earlier in my career, I worked in design and photorealistic 3D visualization. That background still shapes the way I approach interface detail, visual hierarchy and collaboration between product, design and engineering.

Outside the main product work, I continue to explore interface systems, creative 3D, ESP32 boards, sensors and physical prototyping.

Generative AI

Generative AI & Agentic Engineering

I help teams turn isolated AI experiments into structured, maintainable, production-ready capabilities, drawing on my experience as lead architect on agentic architecture projects and as a speaker on Spec-Driven Development at Deloitte; my work spans designing agents with context, tools, and controlled workflows, building specialized agents with clear roles, guardrails, and evaluation criteria, preparing AI-ready repositories through conventions, context files, and reliable prompts, using specifications as a shared execution context for humans and agents, applying AI across discovery, development, testing, and review, and enabling engineering teams through shared practices, governance, reusable delivery patterns, workshops, talks, and practical guidance.
