01 Professional profile · Madrid
Fran Enríquez
Full-stack developer
I turn complex problems into clear, robust and maintainable web products.
I bring the same level of care to frontend and backend: from architecture and data to a precise interface. I add technical judgement, client communication and experience guiding small teams.

03 Selected work
Projects as case files, not display pieces.
Six projects at different scales. The value lies in the problem, decisions and demonstrated capability—not invented metrics.
AI-assisted multimedia catalogue
MediaTag Optimizer
A batch workflow for images and video that turns multimodal analysis into useful, reviewable metadata.
Problem
Cataloguing media at scale requires describing, locating and normalising formats while retaining editorial control over model-generated output.
Contribution
I designed an application that proposes titles, descriptions and keywords; supports review and regeneration; enriches files with GPS context; embeds metadata; and prepares optimised exports.
Capabilities
- Multimodal model adapters
- Human review of generated content
- Image and video processing
- Metadata, conversion and batch export
Stack
- Next.js
- TypeScript
- OpenAI-compatible APIs
- LM Studio
- OpenRouter
B1/B2 English learning
EnglishLoop
A bilingual daily learning experience organised around a clear loop: lesson, practice, review and progress.
Problem
Consistent language revision depends on reducing friction, structuring content and making progress a clear, accessible routine.
Contribution
I built the frontend, bilingual content model, activities, progress states, mock data and validation tooling. Authentication and backend work remain explicitly outside the current scope.
Capabilities
- Responsibility-based frontend architecture
- Content-led internationalisation
- Accessibility and learning flow
- Testing and dataset tooling
Stack
- Next.js
- TypeScript
- React
- Tailwind CSS
- Vitest
Digital wedding planning studio
Nuptia
A full-stack product bringing invitations, event websites, guests, RSVP and a media gallery into one workspace.
Problem
Wedding planning is often fragmented across spreadsheets, group chats, printed stationery and disconnected services.
Contribution
I am building the MVP with domain-oriented architecture and typed contracts. The immediate goal is to close the couple’s essential journeys without presenting evolving modules as finished.
Capabilities
- Invitation editor and microsite
- Guest and RSVP management
- Explicit domain, application and infrastructure layers
- Authentication, typed data and media
Stack
- Next.js 16
- React 19
- TypeScript
- Prisma 7
- tRPC
- Better Auth
- Supabase
- Tailwind CSS 4
Association website
AMODI
A public landing page for Asociación Motril Diverso, with a direct explanation of its purpose and a deliberately maintainable foundation.
Problem
An association needs to explain who it is, what it does and how to get in touch without burdening the team with an oversized system.
Contribution
I created a static architecture, centralised content and a responsive visual system focused on speed, clarity and maintenance.
Capabilities
- Static architecture
- Centralised content
- Responsive design
- Web deployment
Stack
- Astro
- Tailwind CSS
- TypeScript
- Lucide
Institutional digital presence
Sepulcro y Dolores
The official website of a brotherhood, combining institutional content and news on a technical base I continue to update periodically.
Problem
The project needs to preserve its identity, make public information easy to find and support gradual improvements without rebuilding the system every time.
Contribution
I maintain and evolve the Astro implementation, prioritising editorial continuity, performance and a structure that remains understandable as it grows.
Capabilities
- Evolutionary maintenance
- Content architecture
- Static performance
- Visual continuity
Stack
- Astro
- TypeScript
- CSS
- Vercel
04Career
Experience connecting engineering, leadership and service.
I have worked across editorial products, education and mobility. That combination lets me move between architecture, interface, operations and client conversations.
