Hi, I’m Dimitrije Stasic

I build backend systems for healthtech

I'm a computer science junior at Luther College with four software-engineering internships, currently at SkyIT and previously at Mayo Clinic's Digital Health division. On the side I built DormSy, a campus marketplace now live in production.

About Me

A little on where I come from and what I care about building.

I grew up in Serbia and came to Iowa to study computer science at Luther College, graduating in 2027. Most of what I enjoy sits on the backend: data models, APIs, and the unglamorous parts that decide whether a product actually holds up.

I'm drawn to healthtech and medical software: domains where getting the details right matters and the work is worth doing well. I care as much about why something should exist as how it's built.

Away from the keyboard, I played basketball for Luther College, which is where a lot of how I work comes from: showing up, competing, and building something with a team.

  • Backend systems

    Data models, REST APIs, auth, and multi-tenant isolation. The parts that decide whether a product holds up.

  • Healthtech

    Medical software where getting the details right matters: DICOM anonymization, imaging tools, HIPAA-aware design.

  • Team-built

    Four internships and a college basketball career: I work by showing up, competing, and shipping with a team.

  • Shipped to production

    DormSy, a campus marketplace I built solo, is live and in use at Luther College, not just a demo.

Impostor League

Experience & Education

Four software-engineering internships, most recent first.

Backend Developer Intern

SkyIT / GBCS Group

Jun 2026 – Present
  • Contributed to a multi-tenant enterprise ESG and greenhouse-gas emissions platform (Django REST Framework, MySQL, Docker) that serves three branded frontends from one shared backend.
  • Built REST APIs for the emissions engine (Scope 1–4 calculations, AI recommendations) on a DTO-service architecture with JWT authentication and standardized response schemas.
  • Implemented multi-tenant company isolation: derived tenant context from the authenticated user and scoped every database read and write so no company can access another's data, proving it with automated two-tenant isolation tests against a Dockerized MySQL.
  • Developed AI recommendation APIs as a rule-based engine with company-scoped persistence, audit logging, and a documented integration contract for a teammate's module.

Software Engineer Intern

Mayo Clinic · Rochester, MN

Feb 2026 – May 2026
  • Built a browser-based DICOM PHI anonymizer applying 300+ de-identification rules per HIPAA standards.
  • Extended the open-source OHIF medical imaging viewer with a custom React radiology assessment panel.
  • Developed a FastAPI and React user-management system with JWT auth, RBAC, and multi-tenant data isolation.

Software Engineer Intern

Jaka Lounge Human Capital · Belgrade, Serbia

Jul 2025 – Sep 2025
  • Contributed to backend development of a career-verification platform, building database records in Kotlin.
  • Developed company-management features and REST API integrations under senior-engineer supervision.

Software Engineer Intern

WEBX Team · Belgrade, Serbia
