Work
Junior Software Engineer
Built the machine-learning layer of a multi-tenant e-commerce platform: the services that decide what a product is, and what belongs next to it. Each tenant has its own catalogue and its own models.
- Classification
- Product and category classification, from TF-IDF + LinearSVC baselines to fine-tuned Romanian and multilingual transformer models.
- Recommendation
- Semantic similarity, bought-together, up-sell, personalised and buy-again scoring, evaluated with NDCG and hit rate.
- Infrastructure
- FastAPI training and inference endpoints, Redis-backed queues for asynchronous training jobs, per-tenant model storage on S3, cache invalidation on retrain.
