Miguel G.

Frontend Engineer at Roche and Creative Technologist at lhdln.com, sitting at the intersection of frontend engineering, AI tooling, and product craft. I build production UIs, prototype with agents, and push for modern dev practices across a distributed agile team.

Two years shipping with React, vanilla JS, and FreeMarker on Keycloak-based identity platform. I own release coordination across multiple environments, care about accessibility (WCAG AA), and treat testing as a first-class concern, Playwright for E2E, Percy for visual regression, design-system-driven components.

Most of my recent energy goes into AI-assisted development: authoring custom Claude skills, integrating agents into code and test generation, and championing agentic workflows (plan -> implement -> review) as a real productivity multiplier.

Outside work I build AI systems end to end:

• Interactive AI photobooth: local ComfyUI server + custom LoRA, iPad-controlled

• Document processing pipeline — self-hosted n8n + Claude Vision turning handwritten field reports into structured data

• Agentic dev workflows — Cursor, Claude Code, parallel agents via git worktrees

Currently exploring roles where frontend craft meets agentic systems and MCP apps.

Stack: React, Vanilla JS, Keycloak/FreeMarker, NodeJS, python, SQL, Playwright, Percy, Claude API, n8n, ComfyUI.

I don't believe in a unique way of doing things, I believe that everything can be improved and I adapt easily to new environments.
