Software Engineering Intern

Francisco Mustico

May 2027 Graduate

I build production backend systems with C#, ASP.NET Core, and PostgreSQL. Currently an intern at TWIG Power, where I ship tools that real engineering teams use every day.

About

Building Systems That Matter

Francisco Mustico

I'm a software engineering student at Lawrence Technological University with a focus on backend and full-stack development. My internship at TWIG Power showed me the real impact of building reliable systems that teams depend on, and it founded my interest in production backend work.

  • I lean toward backend and full-stack work where clean APIs, data flows, and maintainable architecture matter.
  • Building internal tools and operational software with real users has been the highlight of my work so far.
  • Tutoring in CS sharpened my ability to explain complex concepts clearly, a skill I bring to every team.

Engineering is a team sport. The best systems are built by people who write clean code and communicate clearly.
