Yajala · remote worldwide

Technology that just works.

From the electronic component to the cloud: IT support, networks, IoT, AI and websites with a single point of contact. Yajala is the service brand of Juan Javier Ramírez (“Kira”), the technician who also codes. I work with homes, small businesses, firms and clinics in the Mexico City area, and with remote clients.

S1 · Services

What I can solve

Pick where to start. Each service explains who it is for, what it includes and how I work.

S01 · Server

IT support

Devices, users, backups, email, printers and network: your operation does not stop because of an IT problem. Remote worldwide, on-site in the Mexico City area.

See service
S02 · Network

Networks, servers & CCTV

I design and build office networks, Proxmox servers and IP camera systems: cabling, Wi-Fi, firewall, backups and monitoring.

S03 · IoT

IoT & electronics

When the solution does not exist off the shelf, I build it: sensors, Home Assistant automation, firmware and ESP32 prototypes.

S04 · AI

Applied AI

Assistants that answer from your documents, a WhatsApp chatbot, transcription, smart search and admin automation. AI assists; your team decides.

See service
S05 · Cloud

Web plans

Your website, email on your own domain and backups in one monthly plan, with support and free migration.

S06 · Cloud

Web development

Websites that load fast and rank on Google, plus portals and custom systems. Three demos so you can see the style.

See service
S07 · Server

Data & BI

SQL databases, data cleanup and Power BI or web dashboards, so decisions rest on numbers, not hunches.

See service
S08 · Chip

Reverse engineering

Undocumented protocols, unsupported devices and firmware that needs recovering: I analyze them so they work again or integrate with your systems.

S0 · Why Yajala

A partner, not a vendor

Real depth

I do not just administer systems: I understand what happens inside them, from a chip’s firmware to the website. That shortens diagnoses and avoids unnecessary spending.

Remote first

Anything that can be solved remotely is handled remotely, in English or Spanish; on-site work covers Mexico City and the State of Mexico.

Ongoing support

Call me for a one-off problem, or keep someone who knows your technology and answers when it matters.

S2 · How I work

No surprises
