Selected work, not a repo dump.

This page is a curated read of the work, not a mirror of everything that happens to live on GitHub. The point is selection, framing, and enough context for hiring teams to understand what I built, how I think, and what I learned.

Co-founder

Lead-generation SaaS

Active

LeadQuiry

A platform that turns scattered business prospecting into a clearer and more organized workflow.

What it is

A lead-generation product for businesses that need a simpler way to discover and manage potential customers.

The problem

Prospecting is often spread across searches, spreadsheets, and disconnected tools, making useful leads difficult to track.

What it offers

Users can find relevant businesses, save leads into collections, keep research organized, and export the results for sales.

The team

We are a two-person team. I am co-founder and lead product, while my co-founder leads marketing and growth.

Personal website

Apr 2026

alexcasal.es

A personal portfolio designed to present my work, experience, and current direction without losing personality.

The purpose

My main professional space: part portfolio, part project archive, and part introduction to how I approach digital products.

The previous version

A traditional portfolio can feel generic or make recruiters work too hard to understand the person behind the projects.

Inside the site

A focused view of selected projects, real experiences, ongoing experiments, my background, and clear ways to contact me.

Ongoing direction

I shape the visual direction, write the content, and evolve the site as my work and professional goals change.

Technical assessment

Mar 2026

Zara Challenge

A technical challenge completed for Inditex: turn smartphone data from an API into a polished, responsive frontend.

The challenge

The assignment was to create a product catalogue as part of a frontend technical assessment for Inditex.

The brief

The API provided mobile phones with their images, specifications, and product details—not clothing or fashion items.

The experience

The interface uses responsive layouts and hover states to reveal and organize each phone's information as requested.

The result

A polished frontend that turns raw API data into a clear catalogue and preserves the intended behaviour across screen sizes.

Collaboration

Event website

Jan 2026

HackUDC 2026

The public website for a 400+ participant hackathon organized by the GPUL community.

The event

The official digital home of HackUDC 2026, bringing together the event, programme, sponsors, and practical information.

The audience

A large technical event needs one reliable place where participants, partners, and visitors can understand what is happening.

The website

A clear public reference for schedules, participation details, sponsor visibility, updates, and the identity of the event.

The collaboration

I contributed as part of the web and organizing team, coordinating remotely and supporting public and sponsor-facing communication.

Earlier iteration

Oct 2025

Personal Web

An earlier personal website preserved as a snapshot of how my portfolio and visual direction began.

First iteration

The first complete version of my personal website, created before the current portfolio found its stronger identity and focus.

Why it existed

I needed a simple online presence where I could introduce myself and begin collecting my work in one place.

What it included

A straightforward static portfolio with essential navigation, personal context, project links, and a responsive presentation.

What came next

I designed and developed the full site, using it as the starting point for the portfolio you are viewing now.
