I'm Justina, a software engineer with an eye for detail.

I started by reading books on programming, then I interned at Revocube in 2022, where I got my first hands-on experience building for the web, turning what I was learning into real interfaces.

At ISSL, I grew as a frontend developer, working on real-world projects and learning how software gets built inside a team.

Alongside that, I took on freelance work: websites, online stores and business applications for clients of my own.

That led me to Datamellon, where I work on production software across business applications and dashboards, from frontend architecture and authentication to testing and improving products without breaking the systems behind them.

Then I got curious about what happens beyond the interface.

That took me into AI engineering: APIs, retrieval-augmented generation, vector databases and cloud AI services, and making AI part of products that solve real business problems, not just demos.

The interface is still where I start. It's just not where I stop anymore.
