About Me

I'm Samuel, a developer who really enjoys building things that feel useful and well-made. I care about clean, reliable tools — whether that's a mobile app, a backend service, or just a script that saves someone time. I'm always trying to improve not just what I build, but how I think through problems and work with others.

Lately, I've been working on Barbania, a booking app for small businesses — it's still in progress, but it's been a great way to explore product design, infrastructure, and how to make something simple but helpful. It's also reminded me how much I enjoy long-term projects that grow over time.

In the past, I've worked at startups where I helped build real products for real users — mobile apps, backend systems, internal tools. I've learned a lot about collaboration, making decisions with care, and staying flexible when things change (which they always do).

What I'm looking for now is a team where I can keep learning, contribute meaningfully, and build good software with good people. I'm not looking for a perfect fit — just a place where I can do honest work and grow alongside others who care about what they do.
