Senior Front-End Dev
I use motion and interactivity to build immersive, interactive experiences.
I'm a software engineer with 7 years of experience. I work across the entire stack, specializing on complex front-ends, performance, accessibility and design systems.

The open-source side quest. I dove into the massive Firefox DevTools codebase to ship quality-of-life upgrades for millions of developers:
- DevTools Filtering: Engineered dynamic, React-based filtering for nested console groups inside the Firefox Developer Tools.
- The UI Glitch Patch: Squashed a recursive nesting bug where persistent console groups refused to close across page reloads.
- Telemetry Wiring: Hooked up core telemetry tracking for the console's reverse search feature to map out developer usage patterns.

Full Stack Developer & Researcher
I developed rapid prototypes, each with completely different tech stacks for startups:
- Load Testing Tooling: Bypassed resource-hogging Chrome browsers with a custom, ultra-lightweight load-testing prototype.
- Network Recon: Built a custom TCP packet sniffing device using a Raspberry Pi, C, Bash, and Python.
- 3D Biometrics: Engineered an anthro-photogrammetry Blender plugin to calculate precise body measurements from 3D human meshes.
- Content Aggregation: Shipped a full-stack blog aggregator to tie it all together.
My Stack
I've worked with a lot of different tech over the years, but I don't get too caught up in the stack. At the end of the day, a programming language is just a tool to solve a problem.
Below is a list of the technologies I've worked with and my level of expertise in each:
TypeScript
Redux
React
GraphQL
Claude Code
Three.js
Figma
Node.js
Astro
Sanity
GSAP
Python
Next.js
Go
Storybook
Express.js
Git & Github

Hello, I'm Miguel but you can call me Miggs.

Skills
Skills
Astro
When I need a blazing-fast site, this is my go-to. I pair Astro's architecture with complex GSAP animations and headless CMS setups to give clients hyper-performant, SEO-friendly experiences.
Claude
I use AI tools like the Claude Code CLI as my co-pilot to accelerate my full-stack development, brainstorm complex logic, and maintain high code quality across the board.
Figma
I leverage the Figma MCP in my AI workflows and sync design systems directly to component libraries using Figma Code Connect, preventing drift and making hand-off seamless.
Sanity CMS
I empower my clients by wiring up this headless CMS into modern frontends. It lets them easily manage their content behind the scenes.
React
I’ve spent years architecting and maintaining production-scale React UIs for enterprise customers. I know how to wrangle messy asynchronous data flows and global state without sacrificing front-end performance.
GSAP
I don't just use GSAP; I build systems around it. I created a custom TypeScript animation library where I scoped every ScrollTrigger to its specific component, eliminating memory leaks across complex pin and unpin cycles.
Three.js
I love breaking out of the standard 2D DOM. I use Three.js to custom-code immersive 3D experiences that integrate seamlessly into the bespoke sites I build for my clients.
TypeScript
The backbone of everything I build. I rely on strict typing to keep my highly interactive codebases bug-free, whether I'm writing custom frontend elements or building robust backend REST integrations.
