Open to joining a development team

.NET Developer with an analyst mindset.

Systems Analyst and Systems Engineering student. I build C# and .NET applications with layered architecture, design patterns and optimized SQL Server persistence.

The architecture I apply

C# · .NET
Presentation WinForms · validation · UI state
Business logic rules · Singleton · Observer · Composite
Data access ADO.NET · stored procedures · indexes

This is how I structured the library manager in .NET Framework: separate layers, each with a single responsibility.

01

Profile

I am a systems analyst and an advanced student of Systems Engineering. My approach combines methodical problem-solving with solid architecture and layered design before writing code.

I specialize in backend development with C# and .NET, using SQL Server as the primary database engine. I have experience building mobile applications in React Native integrated with REST APIs, and in the collaborative development of web management systems in ASP.NET, where I took ownership of key business modules and data integrity.

Method

Four steps I always follow, in this order.

  1. 01

    Gather

    I talk to the people who will use the system before proposing solutions. At the school site I interviewed academic and management staff to define the real sections.

  2. 02

    Model

    Use cases, sequence diagrams and layered architecture before the first line of code. Deciding here is free; deciding later costs a refactor.

  3. 03

    Build

    C# and .NET with patterns where they add concrete value, not for the sake of it. I prioritize that the next person reading the code understands the intent.

  4. 04

    Measure

    I measure before and after every change to queries, indexes and stored procedures. An optimization without measurement is just a guess.

03

Projects

Three systems built end to end, each with its own stack and technical decisions.

Let's talk

I am looking for my first role as a .NET developer. If your team needs someone who understands the problem before writing the first line, get in touch.
