Julio Oña

Senior Python Engineer with 14+ years of experience building and operating scalable backend/full-stack systems for SaaS, on-prem, and AI-enabled products. I design APIs and async workflows using Django/DRF/FastAPI, Celery/Huey, PostgreSQL, Redis/RabbitMQ, and cloud platforms (AWS/GCP/Azure). Key achievements include leading Python 2→3 modernization, shipping AI orchestration services, and improving production reliability and performance across multi-service environments through safer migrations, observability, and incident-response ownership. I’m seeking a remote Senior Python Backend/Full Stack role where I can own projects end-to-end, collaborate with product and ML teams, mentor engineers, and deliver measurable business impact.
