Senior Developer with 5+ years building and operating production systems in Python/Django on AWS. I've integrated complex third-party APIs (including Enedis, the French national electricity grid operator), delivered an end-to-end invoicing platform for an electricity supplier, and led a small team through refactoring, feature delivery and CI/CD adoption. I also bring hands-on applied ML experience: fine-tuning BERT models on SageMaker and serving real-time NLP inference on AWS Lambda.
