Track record
Where I've been shipping.
Four years of building production web applications — first as a junior turning into a team lead, now owning architecture and AI features end-to-end.
- Nov 2023 — PresentMurcia, Spain (Remote)
Full-Stack / Product EngineerTututor.ai
Building an AI-native education platform serving 17,000+ students and teachers across schools in Murcia, Spain. Reduced lesson-prep time by 90–95% via AI-generated content. Own architecture for AI services, the school CRM, and core student experience.
- Designed and shipped an AI chatbot system letting teachers spin up topic-specific tutors; teachers review student conversations to surface gaps.
- Built AI quiz generator with automatic grading and per-class performance analytics on top of lesson content.
- Architected the school CRM (students, classes, content) so admins manage everything from one platform.
- Migrated heavy AI flows behind WebSockets + a microservices boundary to keep teacher UX responsive under load.

React DeveloperDanzee Tech
Joined as a junior, grew into the go-to for new teammates and feature owner across two years. Frontend-led but owned chunks of Node/Express — JWT auth, payments, third-party integrations.
- Built an internal component + hooks library that became the team's default ship surface, cutting handoff churn on new screens.
- Diagnosed and fixed query/indexing hotspots when API latency spiked under load.
- Shipped frontend for Jurri (cloud storage + multi-email platform): drag-and-drop uploads, unified inbox, password vault.
- Code-split + lazy-loaded the bundle to drop initial load ~40%.

How I think about the work
Four things I won't compromise on.
01
Ship to users, not to portfolios.
Every project on this site is in production with real people relying on it. Demo-quality code is a different sport.
02
Architecture is the feature.
The hard part of an AI feature isn't the prompt — it's the streaming, the storage shape, the failure modes, the latency budget.
03
Design is part of the job.
Most of my work has been at startups without a designer. I've learned to think in flows before I think in components.
04
Speed is a feature for the user, not the developer.
I'll optimize the bundle, the queries, and the layout shift — because users feel slowness even when they can't name it.

I'm open to a small number of senior product engineering roles and AI engineering engagements. If you're shipping to real users, let's talk.
