From first sketch to maintenance

I work with businesses and individuals who need reliable, fast and secure software.

Custom websites & apps
Fast, bilingual, easy-to-update websites with a content panel, and web apps built for your business.
Maintenance
Updates, fixes and new features after launch, so your software stays secure and useful.
Software
Management apps for day-to-day operations: stock, bookings, deliveries, teams, with real-time data.
Security reviews
A review of your current site and domain: risks, evidence and a clear plan to fix them.

How I work

Conversation
I learn the problem, the goals and what already exists.
Proposal
A clear plan with deadlines and a fixed price.
Build
Live previews early on, always tested.
Launch & maintenance
Go-live, training and support after launch.

About me

Down-to-earth engineering

I'm a software developer based in Porto. I like solving concrete problems: a student residence that stopped running everything on paper, a law firm with a fast, secure site that's easy to update.

I work mostly with C# and .NET, Blazor and MAUI, Supabase and PostgreSQL, and Astro and React on the web. Every project ships with automated tests, documentation and GDPR in mind from day one.

I'm currently finishing my Master's at ISEP and open to new projects and opportunities.

Location: Porto, Portugal
