I'm Alexandre — a senior .NET engineer in Brasília. I design, build and ship complete corporate systems: architecture to production, web to mobile, data model to deploy. You brief one technical owner instead of assembling a team.
Full corporate web applications in ASP.NET Core & Blazor — from the domain model to a running production deploy, not just a front end bolted onto someone else's API.
Native mobile apps in .NET MAUI that plug straight into your existing .NET backend — one language, one team, no second stack to maintain.
Bring aging Web Forms and old MVC systems onto modern ASP.NET Core — safely, incrementally, without stopping the business that depends on them.
Make slow systems fast: SQL Server tuning, indexed views, and query work that turns sluggish grids and dashboards into instant ones.
Wire your system into the services it needs — WhatsApp Business via Twilio, cloud APIs, third-party platforms — reliably and securely.
AI built into the product itself — recommendations, analysis, smart search your users actually touch. Not AI to write code, but AI as a real feature, as in TrackList's "more like this" engine.
One person accountable for the whole thing — from data model to production.
Shared C# across mobile and web — one codebase mindset, from device to server.
Not screenshots — real, running instances of systems I built, hosted here for you to open and click through yourself. Deploying now on their own subdomains.
Isolated demo environments with sample data — reset daily. No production data.
The full fleet-management platform, running live. Browse trips, vehicles, dashboards and contracts as a real navigable instance.
The vehicle-inspection app for field teams — a real .NET MAUI build you can run, connected to the same backend over Azure Relay.
Real-time passenger counting and operational data from the field — the second .NET MAUI companion app, live and navigable.
A movie & series catalog I built end to end — with an AI engine that recommends similar titles from what you've watched. A live instance you can sign into and use.
