Small shop. Local focus.
Datalynlabs is me — Kevin Rosario — a designer and engineer based in San Juan, PR. I build websites for contractors, clinics, and service businesses across Puerto Rico. One operator, 3 weeks builds, care plans that keep your site earning long after launch.
One operator. On purpose.
Discovery → design → launch → care. Every page, every word, every line of code — done by one person. You talk to the same human who answers the phone, draws the mockup, and pushes the code. Decisions land in hours, not weeks.
Local, on purpose. I built an island-wide practice because local owners get burned by faraway agencies that disappear after launch. I live here, I drive here, and I meet you in person when it matters.
Ownership, never lock-in. Clean code, your domain, your Google Business login, your Care Plan you can cancel. The day the site ships, it is yours — full stop. I stay because the work earns it, not because you are trapped.
02 — SHIP IN WEEKS, NOT MONTHS
03 — PHONE CALLS OVER CONTACT FORMS
04 — OWNERSHIP, NEVER LOCK-IN
05 — PROOF LIVES IN BOOKINGS
The best website you'll
ever launch is the one
that earns its keep.
What I'll sign my name to.
I reply to every inquiry within one business day — usually faster. No auto-responders, no call centers, no sales team.
No lock-in, ever. The day your site launches I hand over every login — domain, repo, Google Business, analytics. You own it.
If your site doesn't load in under 2 seconds, rank for your main local search, or pass Lighthouse 95+, I'll fix it on my dime.
