$ nikko run intro
I build web platforms with applied AI and Edge Computing. In production, not in demos.
I build sites that load fast and don't waste a byte. Landing pages, AI apps and automation. Real cases: an education platform that went from 3s to 0.2s, and a system running 13 research groups at UNAL.

/ services
Digital solutions for businesses that need results.
Design that seduces, technology that backs it up. Every pixel has purpose, every interaction creates value. Not magic — obsession with detail.
Web Apps with AI
Platforms with login, smart chatbots, AI APIs and admin dashboards. Ideal for startups that want to launch fast without overspending.
Optimization & Automation
Slow pages? Repetitive processes? I improve load speed, connect tools, build bots and automate tasks so your business saves time and money.
AI Education
Workshops for schools and institutions on artificial intelligence, prompting, agents and practical uses. No hype, just tools that work.
// what I built
Not screenshots. Real stories.
Every project has a problem, a technical decision and a measurable result. Not everything went perfect — and that matters too.
View demo ↗ The problem
A foundation working to reduce lack of access to pre-university education. The real problem: students without resources who need quality material.
What I did
We implemented OAuth with Microsoft and Google, a PWA so it works offline and on low-end devices. The point of a PWA here isn't hype — it's that a student with an $80 phone and limited data can study without constant signal.
Result
A functional platform with multi-layer authentication, Llama 3.1 chatbot, and Edge infrastructure that practically costs nothing.
What I'd do differently
Measure from day one. We built half of it in a rush and real usage metrics were missing.
$ npm run status --project=SinPresupuesto ✓ 3s → 0.2s optimization · ✓ offline PWA · ✓ AI integrated
View demo ↗ The problem
It was a mess of emails, loose PDFs and WhatsApp groups. There was nothing to centralize information about seedbeds and research groups.
What I did
We built a platform with Astro, Supabase and PostgreSQL. Group catalog, role management, application forms. What used to be solved with endless email threads now gets solved with a login and a dashboard.
Why that stack?
Astro because it spits out static HTML and loads instantly. Supabase because it gives me auth, database and storage without building a backend from scratch. PostgreSQL because a faculty's relational data isn't handled with a loose JSON file.
What I learned
It's my biggest project so far. And the one that's taught me the most about working with non-technical people whose requirements change every week.
$ npm run status --project=FIBOG ✓ 13 groups managed · ✓ 11k+ lines · ✓ in production
View demo ↗ The problem
A vehicle repair business needed real digital presence. Not a business card, but something that showed up on Google and generated contacts.
What I did
Landing in Astro with GSAP. Technical SEO, smooth animations, responsive, direct CTA to WhatsApp. All optimized to load fast on mobile — where most customers search.
Result
Functional digital presence for a business that had nothing. Fast load, basic SEO implemented and direct WhatsApp contact.
What I'd learn next
I'd implement analytics from day 1 to measure real conversions, not just assume.
$ npm run status --project=Autorreparacion ✓ Real client · ✓ SEO implemented · ✓ WhatsApp CTA
View demo ↗ The problem
An automatic doors company with no professional web presence. They needed something that built trust and showed up in local searches.
What I did
Landing in Astro focused on SEO, responsive design and clean commercial presentation. Complete individual development.
Result
Live, functional site for a physical business that needed to go digital. Simple, fast, effective.
What I'd learn next
I'd schedule a content review with the client before deploy. Sometimes technical copy doesn't connect with the actual audience.
$ npm run status --project=InduSEC ✓ Landing live · ✓ Local presence · ✓ 100% individual
// who I am
If we grab coffee and you ask what I do:
I believe in the beauty of the essential. Every line of code is a conscious decision, every animation a visual caress, every millisecond saved a gift to those who choose us. I don't collect titles, I collect trust: from UNAL that shaped me, from companies that saw their idea come alive, from every user who finds what they seek effortlessly. Second year of engineering, yes. But with the maturity of someone who understands that the most elegant technology is that which becomes invisible.
"True sophistication isn't seen. It's felt."
