I build fast, scalable web products, from the first idea to production. I care about great user experience and shipping software that delivers real results for people and businesses.
+---------------------+---------------------+ | 15+ | 4+ | | years working in | years as a | | technology | full stack developer| +---------------------+---------------------+ | 45+ | 6 | | projects delivered | sites delivered per | | and producing value | month in 2026 | +---------------------+---------------------+
Real businesses, real deadlines, real numbers. Each window is a site that shipped; open a case to read it.
.--------------------------------------------. | o chezboaztours.domirandar.workers.dev | |============================================| | CHEZ BOAZ TOURS | | Tourism · Santa Marta, Colombia · 2026 | | | | Rebuilt with online booking and deposits: | | mobile load time down from 7.9 s to 1.6 s. | '--------------------------------------------'
The problem. Their WordPress site took almost 8 seconds to load on mobile, had broken buttons and sections that never rendered, and could not take a single payment online.
What I built. I rebuilt it from scratch as a static Astro site on Cloudflare Workers: 2026 tour catalogue, cart, checkout with a 30% deposit through Bold, and TravelAgency structured data.
Mobile LCP before 7.90 s ########################## after 1.62 s ##### Page weight before 3.1 MB ########################## after 499 KB #### Blocking time before 2,905 ms ########################## after 211 ms ## Requests before 102 ########################## after 15 ####
Role: Design & full stack · Built with Astro, TypeScript, Cloudflare Workers, D1, Bold
.--------------------------------------------. | o o o climbrock.domirandar.workers.dev | |============================================| | CLIMB ROCK | | Industrial safety · Bogotá, Colombia · | | 2026 | | | | Their first website: six service lines and | | a quote request in a single tap. | '--------------------------------------------'
The problem. A fall-protection engineering company that manufactures its own hardware had no website at all: every quote request arrived through Facebook or word of mouth.
What I built. A server-rendered Astro site on Cloudflare Workers covering their six service lines, with real project photography, the Resolution 4272 of 2021 compliance story and one-tap WhatsApp quoting.
Role: Design & full stack · Built with Astro, SSR, Cloudflare Workers, Supabase, TypeScript
.--------------------------------------------. | o o o opticasapolovision.com | |============================================| | ÓPTICAS APOLO VISIÓN | | Optical retail · Bogotá & Girardot, | | Colombia · 2026 | | | | Online store with a searchable catalogue, | | nationwide shipping and eye-exam booking. | '--------------------------------------------'
The problem. An optician with two branches and fifteen years of customers could only sell in person — there was no way to browse frames or book an eye exam online.
What I built. A custom e-commerce store with a searchable catalogue of sunglasses, frames, lenses and drops, cart and checkout, nationwide shipping and online eye-exam booking.
Role: Design & full stack · Built with Next.js, TypeScript, Tailwind CSS, E-commerce
.--------------------------------------------. | o o o private platform | |============================================| | AGRO LEDGER | | Agritech · Traceability & compliance · | | 2025 – 2026 | | | | Plant-to-batch traceability platform for a | | regulated crop, built for audits. | '--------------------------------------------'
The problem. Regulated cannabis cultivation has to prove the traceability of every plant, and the operation was tracking it on spreadsheets that no audit would accept.
What I built. I led the development of the agricultural management and traceability platform: batch tracking, roles and auditing, aligned with Colombian regulation and international standards.
Role: Tech lead & full stack · Built with Next.js, NestJS, PostgreSQL, Docker, TypeScript · Client: Colombian Cannabis Center
.--------------------------------------------. | o o o rescatista.vercel.app | |============================================| | KEVIN GALEANO — RESCATISTA | | Personal brand · Rescue & training · 2026 | | | | Personal brand with a gallery of real | | operations and every channel in one place. | '--------------------------------------------'
The problem. A firefighter and vertical-rescue instructor with fifteen years in the field had his whole portfolio scattered across social media, with nowhere to send a prospective client.
What I built. A personal site with a Cloudinary-backed photo gallery of real operations, his service lines and direct contact through every channel he already used.
Role: Design & front end · Built with Next.js, Tailwind CSS, Cloudinary
A backend has no screen, so here is the part that matters. Buying a raffle ticket, in one transaction with a row lock, so two buyers can never take the same number:
sequelize.transaction(async (tx) => {
// lock the row: nobody else can touch it
const raffle = await Raffle.findByPk(id, {
lock: Transaction.LOCK.UPDATE,
transaction: tx,
});
if (raffle.status !== 'active')
throw new BadRequest('not active');
if (raffle.tickets[number])
throw new BadRequest(`${number} is sold`);
// mark it sold + create the ticket, same tx
});

I live in Colombia. Before code there were hardware, networks and servers; around it all, mountains, tour guiding and a bass guitar. All of it shows up in how I build: I care about the people who will use the thing.
I write in Spanish, at daev.space/blog. The latest:
