Summary

Associate Engineer and full-stack web developer building production healthcare software with Python, Django, Django REST Framework, JavaScript, and relational databases. At Corunit Media Corp I work across a production EMR platform — patient intake, clinical documentation, scheduling, billing, authorization forms, ticketing, and administration — with responsibilities that have grown from frontend development into backend engineering, database design, API development, deployment, and production maintenance.

I have also led a B2B customer portal from planning to AWS deployment, and bring a foundation in machine learning and NLP from building SMS-spam and hate-speech classifiers. I care about secure, maintainable, user-centred systems and keep deepening my engineering across backend, cloud, and AI-enabled applications.
