The senior engineering voice on the surfaces users touch.
Background, leadership philosophy, and how Diogo Esteves works as a Staff/Principal frontend & platform engineer.
I build the engineering systems behind ambitious products. For 11+ years I've been the senior engineering voice on platforms used by millions — streaming at Sky and Peacock, governance software at Diligent, innovation systems at BMW Group, and AI-native products at eino.ai, Moment, and Fueled.
I've operated at both ends of the spectrum: founding-engineer altitude inside seed to Series B AI startups, and Staff / Lead altitude inside Fortune-class enterprises with strict reliability, accessibility, and compliance constraints.
I'm most useful to teams where the frontend is the product — not a thin layer over an API — where AI is a first-class part of the experience, and where architectural taste, hiring leverage, and execution speed compound.
What I actually do
- Architect frontend platforms — design systems, monorepos, micro frontends, and developer experience that make product teams faster.
- Build AI-native product surfaces — agentic UX, RAG-backed flows, and the human-in-the-loop patterns that make LLMs feel like real software.
- Lead engineering organizations — hiring, leveling, technical strategy, and the operating system of a high-trust, async, shipping-oriented team.
- Translate business ambiguity into durable architecture, partnering directly with founders, CTOs, and product leadership.
Beyond the code
- Portuguese (native) · English (full professional).
- Computer Engineering at ISEL — after an LLB in Law.
- Meta Front-End Developer Professional Certificate.
