maccari78/README.md

Full Stack Developer with experience in critical production systems. I was the sole developer responsible for IPS RUPA, a provincial government platform (Django + Next.js + PostgreSQL) handling millions of records for members, employers, and payroll. I managed every stage: REST API design, frontend migration, adaptation to an immovable legacy schema (Adabas D → PostgreSQL), integration of 90+ GB of production data with Celery and streaming, and deployment on Kubernetes (OKD/OpenShift) coordinated with the DevOps team. In parallel, I founded and built DocSync, a medical clinic management SaaS with multi-tenant architecture (PostgreSQL Row Level Security), now live in production on AWS with a mobile app approved on Google Play. I've applied this same multi-tenant expertise across other freelance projects, turning single-account MVPs into scalable, multi-client SaaS products. Strong focus on clean code, security, and continuous delivery, with an emphasis on taking products from idea to real production.
