I’m a Django-focused product engineer who builds and operates production-ready systems—anchoring reliability in backend architecture, PostgreSQL data modelling, APIs, security, and CI/CD. Since starting with Django in October 2022, I’ve steadily grown my work from framework fundamentals into real-world delivery: migrations, domain boundaries, authentication/authorization, and production workflows that stand up to change. I enjoy working backend-first, while still being able to cross into React/TypeScript, HTMX, and mobile when the product needs it. I’ve built multi-client platforms using Django, PostgreSQL, Redis, and Celery, and I value clear decisions, testable services, and continuous improvement—using AI-assisted tools to speed up development and edge-case thinking while always verifying outcomes.…I’m a Django-focused product engineer who builds and operates production-ready systems—anchoring reliability in backend architecture, PostgreSQL data modelling, APIs, security, and CI/CD.
