Data Scientist Intern, Data Science Immersion Program (DSIP 4)
Djezzy × MajestEYE / Algiers, Algeria
Led a five-person team building the Djezzy Commercial Copilot, a multi-agent business-intelligence assistant for the commercial department, during the 6-week internship.
- -Led the five-person team (the lead role was agreed within the team) and owned the shared architecture: the Temporal/LangGraph runtime, the async delivery pipeline and the CI gates
- -Designed the async execution pipeline: task submission, durable Temporal workflow, Kafka completion events, and WebSocket delivery, so heavy analytical queries never block behind a spinner
- -Built guarded natural-language-to-SQL generation validated by sqlglot before it reaches a read-only analytical warehouse spanning 13 months of daily commercial data
- -Implemented a date-normalization engine for statistically fair period comparisons around holidays and campaigns, plus a pgvector-backed shared memory layer to avoid recomputing solved analyses
