Shellrean

Senior Fullstack Software Developer
Developer at Extraodev

I build software that is simple, maintainable, and made to last.

Website · dev.to · YouTube

About

I enjoy turning complex problems into clear, dependable systems—from APIs and databases to the interfaces people use every day.

My work mostly revolves around backend engineering, system design, and building production software with sensible architecture. I also write about what I learn along the way.

Currently exploring Rust and Axum for high-performance systems.

I work with

PHP · Go · Java · Rust

Laravel · GoFiber · Vue.js · FastAPI · Spring · Axum

MySQL · PostgreSQL · MongoDB · Qdrant

How I build

  • Keep the solution as simple as the problem allows.
  • Prefer clear boundaries over clever abstractions.
  • Design APIs for the people who will maintain them.
  • Ship, observe, learn, and improve.

Writing

I document practical notes, technical experiments, and lessons from building software.
