WHOISKAWHAN / SOFTWARE ENGINEER / João Pessoa
APPLIED ENGINEERING
I am Kawhan. Four years building software, currently on systems for industrial automation. I write code for two reasons: to solve a real problem, and to get an idea off paper — until it runs, it is still a guess.

5 PROJECTS / REPOSITORY
Opportunity again, this time split into microservices with Spring Boot, Eureka for service discovery and a gateway handling authentication. The question was whether I could make it scale without turning it into a distributed mess.
A job board for UFPB Campus IV: students and professors sign in with their institutional email, and charts show who showed interest in which opening. Django, PostgreSQL, JWT and Docker.
A .NET API written with real DDD, not slide-deck DDD. Entity Framework, dynamic validation through FluentValidation, and Swagger for whoever consumes it.
A .NET MVC CRUD built to learn the framework properly: authentication, permissions per user level, and password recovery over SMTP. Nothing exotic, everything working.
Reimplementing the C standard library at 42 São Paulo. No garbage collector, no safety net — just malloc, free, and the consequences of getting it wrong.

Things I wanted to prove would work, so I built them.
