01 — About me
Ten years of building production interfaces — I'm Andres Hernandez, a Fullstack Developer from Bogotá, Colombia.
Speed without care just breaks faster — that's what those ten years, and a run as Senior Frontend Developer at Mercado Libre Colombia, taught me.
AI didn't replace my process, it sharpened it: less time on boilerplate, more time understanding what users actually need.
I build because I love turning complicated into simple. Clean code, good music, and an anime marathon — that's the mix that feels like me.
02 — Experience
From an agency in Bogotá to Latin America's biggest marketplace — now freelance from Melbourne.

One stack, start to finish — no hand-offs, no excuses.
Each row opens and shows the tools I actually use for that part of the job.
React, Next.js, and Tailwind CSS — GraphQL and Apollo when data gets complex.
Node.js, Express, and Nest.js, with PostgreSQL or MongoDB behind them.
Tested with Jest, Testing Library, and Cypress; tuned with Lighthouse.
Docker on AWS, versioned with Git, sketched in Figma before it's code.
Faster prototypes, earlier edge cases, more time on what users actually need.

Scroll · cards stack up
An open source marketplace where the platform buys what people no longer use: list an item, get an offer, accept it, and they pick it up and pay you. Offers, chat and notifications all travel live over one authenticated WebSocket.
AI SEO audits and daily Google rank tracking. A real browser renders the page, 20 checks and Gemini grade it, an assistant explains what to fix, and every morning it checks keyword positions per country, with email alerts.
A living gallery of hand-built frontend experiments, from vanilla JS to React + TypeScript. Each one starts from a brief and gets its own name, visual identity and GSAP motion, all served from one bilingual Astro site.
05 — Code
Not every project makes it into a case study. Some just get built anyway — these are a few that did.
A living gallery of hand-built frontend experiments. Original designs, GSAP motion and real interactions, from vanilla JS to React + TypeScript, served from one Astro site.
