Acerca de Demian Louis
Available immediately. Senior full-stack software engineer with 7+ years of experience, specialising in React and TypeScript to deliver accessible, high-performance user interfaces and reusable component systems that help product teams ship and iterate quickly.
I complement strong frontend expertise with Kotlin / Spring Boot backend development, allowing me to deliver complete features end-to-end — from API design and data modelling through to UI integration, testing, and deployment. I’m pragmatic, detail-oriented, and comfortable working closely with designers and product owners to translate product goals into polished, production-ready features.
I’m experienced working autonomously in senior contract roles, able to ramp up quickly, navigate unfamiliar codebases, and contribute meaningful value with minimal oversight. I place a strong emphasis on maintainability, observability, and long-term code health.
Typical projects I support include:
• Frontend builds and refactors
• Design systems and component libraries
• End-to-end feature delivery
• REST APIs and third-party integrations (including SaMD medical AI)
Selected experience:
• Exam priority system — delivered UI and backend changes to prioritise live exams and accelerate critical result delivery
• SaMD AI integration — integrated third-party medical AI into existing workflows to expand diagnostic capability
• Admin dashboards — built focused dashboards with filters and actionable views to speed issue triage for support and stakeholders
• Sentry rollout — implemented organisation-wide monitoring and triage documentation, reducing mean time to resolution
Available for short engagements as well as longer-term collaborations (3–12 months).
