/about

A Human Layer

I care about building useful software with people, not just shipping isolated pieces of code.

My engineering taste comes from product work, platform thinking, and a habit of making tools understandable for the teams around them.

01 [team]

Team rhythm

I grew up playing federated football, which shaped how I understand discipline, roles, feedback, and showing up for a group over time.

02 {learn}

Learning mode

I tend to follow curiosity into tools, interfaces, AI workflows, implementation details, and startup thinking until I can turn them into practical habits.

03 <voice>

Communication range

I work comfortably across technical and product contexts, with C1 English, public speaking experience, and a preference for clear explanations.

Design systems at scale

Reusable UI infrastructure, Storybook documentation, accessibility practices, release workflows, and component quality for frontend teams.

AI-assisted engineering

Using coding agents, MCP servers, context engineering, and structured prompts to move faster without losing code ownership.

Product-minded delivery

Balancing technical quality, maintainability, UX, and business value across product-facing onboarding flows.

Cross-team collaboration

Working across product, design, backend, QA, and regional needs to turn complex financial journeys into usable software.

Development Philosophy

“Strong knowledge fundamentals are the key. Technologies and frameworks come and go; they are tools that help engineers solve business problems.”

/agent

Profile Chat

A small AI interface over Miguel's curated CV data. It is meant to answer focused questions about experience, projects, working style, education, and AI engineering practice.

Grounded retrieval

The worker selects profile facts, CV sections, projects, and recent public updates before calling the model.

Context engineering

Questions are classified by likely audience and intent, then assembled into a compact system prompt with explicit answer rules.

Deterministic evals

Node tests verify that key questions retrieve the expected profile context without depending on a live LLM response.

Streaming UX

The Cloudflare Worker adapts upstream SSE into the AI SDK UI message stream used by the drawer chat.

Operational guardrails

CORS, rate limits, upstream retries, timeout handling, and a secondary backend keep failures visible and recoverable.
