01About

Software that solves the real problem, not just the ticket.

I'm John Edgar Francisco, a software engineer who has been shipping production systems since 2018: school management platforms, campaign dashboards, fleet service tools for a UAE leasing company, and my own apps on Android, the web, and desktop with Electron.

I'm happiest on the backend (clean APIs, well-shaped databases, background jobs that don't fall over), and I carry that care all the way to the interface people actually use.

One engineer across the whole stack.

Clean, maintainable code and sensible defaults, so what I build keeps working long after launch.

How I work

From idea to production in four phases.

  1. 01

    Discovery

    Understand the goal, the users, and the must-have features before writing a single line of code.

  2. 02

    Design & Planning

    Wireframes, data model, and stack decisions settled early so the build phase has zero guesswork.

  3. 03

    Build

    Working increments with clean, maintainable code — following best practices every step of the way.

  4. 04

    Launch & Support

    Deploy, verify, and stay around for fixes and improvements — no disappearing after handoff.

In practice

What that looks like day to day.

  • I build server-side JavaScript with Node.js and Express: scalable, high-performance APIs and real-time services.
  • I build backend services with Python and FastAPI, using Redis for caching and PostgreSQL for data.
  • I specialize in building interactive and responsive user interfaces with ReactJS and enhance the development process with TypeScript for improved code quality and maintainability.
  • Proficient in designing and optimizing databases, I have hands-on experience with MySQL and PostgreSQL, ensuring data integrity and efficient query performance.
  • I build cross-platform apps: React Native for Android and iOS, and Electron for desktop applications.
  • I have also built web applications and backend APIs in PHP, with CodeIgniter and Laravel.
  • I containerize applications with Docker for consistent, reproducible deployments.
  • Experience running Ubuntu Linux servers.
  • MySQL Functions, Triggers and Stored Procedures.
  • Solid grasp of object-oriented programming.
  • Comfortable in Agile teams and the full software development life cycle.
  • I use Claude as an AI pair programmer to speed up coding, debugging, and code reviews.

04Community

Open source and the people behind it.

Beyond client work, I build and contribute to open-source projects and keep learning alongside developer communities.
