Available for new projects

Software and systems built from scratch, around what your business actually needs.

I don't sell templates or licenses you'll never use. I look at how your operation works, find where time or money is being lost, and build the exact solution: from infrastructure and servers to the mobile app or SaaS platform your team will use every day.

IT System Administration

I design, deploy and maintain the infrastructure your business runs on, so it stops being a problem and becomes something you never have to think about.

  • Linux and Windows Server administration
  • Networks, firewalls, VPN and secure remote access
  • Virtualization and containers (Proxmox, Docker)
  • Backup, disaster recovery and business continuity strategies
  • Monitoring, task automation and security hardening
  • Cloud migration and hybrid environment management

Mobile Development

Android apps published and maintained end to end, including the whole Google Play process: store listings, releases, closed testing and policy compliance.

  • Native and cross-platform Android apps
  • Integration with APIs, databases and cloud services
  • Full publishing and management in Google Play Console
  • Updates, crash monitoring and ongoing support

03

Custom SaaS

Web platforms built from scratch for when off-the-shelf software doesn't fit the way you work. You describe the process; I turn it into a system.

  • Admin panels and dashboards with real metrics
  • User, role and permission management
  • Subscriptions, billing and payment integration
  • APIs and automations between the tools you already use
  • Hosting, deployment and maintenance included

How I work

  1. Initial conversation

    Free of charge. You tell me what you need and what's holding you back today.

  2. Clear proposal

    Defined scope, estimated timeline and a fixed price. No surprises halfway through the project.

  3. Development with partial deliveries

    You see real progress throughout the process, not just at the end.

  4. Delivery and support

    Documentation, training if needed, and ongoing maintenance if you want it.

About JJDevSolutions

JJDevSolutions is the project of Jose Alvarado, an IT professional based in Puerto Rico with experience in system administration and software development.

You work directly with me: no middlemen, no rotating teams, no lost tickets. The person who plans your solution is the same one who builds it and the one who answers when something needs attention.

My approach is simple: understand the problem before writing a single line of code, and deliver something people will actually use.

Frequently asked questions

Do you work with clients outside Puerto Rico?

Yes. Projects are handled remotely without any issues, and I schedule meetings around your time zone.

How much does a project cost?

It depends on the scope. After the initial conversation you get a proposal with a fixed price, not an open-ended hourly rate.

Do you offer maintenance after delivery?

Yes. You can hire monthly support or request one-off interventions whenever you need them.

Can you take over a project someone else started?

Yes, as long as I can first review the state of the code or the infrastructure to give you an honest diagnosis.
