Sarra Chamekh

I'm a 4th year Computer Science Engineering student at ESPRIT in Tunis, focusing on actuarial engineering and FinTech. Over the past two months at BH Assurance I've been splitting my time between non life IBNR reserving (Chain Ladder, Bornhuetter Ferguson, Mack LDF) and insurance contract verification (Auto, Motorcycle, Fire). On the side I build full stack apps (Angular, Spring Boot, FastAPI, Go).

I'm looking for a six month end of studies internship starting February 2027, ideally outside Tunisia.

Intern, Actuarial Engineering and Contract Verification at BH Assurance (2026-07 – 2026-08)

IBNR reserving and data tooling

• Built a non life IBNR reserving engine in Python (Chain Ladder, Bornhuetter Ferguson, average cost). The reproducible pipeline replaced the manual Excel workflow the team was using
• Constructed run off triangles from BH's claims history, applied Mack's volume weighted LDF and corrected outliers using Tukey box plots
• Wired in an XAI module based on SHAP to explain the ML predictions, plus an ALM prototype that projects claims cash flows and runs sensitivity analysis
• The Streamlit + Python pipeline cut IBNR reserve calculation time from roughly two days (Excel) to fifteen minutes, and the audit trail is now used by the Technical Department
• Reviewed several hundred Auto, Motorcycle and Fire insurance contracts for compliance with BH's internal procedures and CGA (Comité Général des Assurances) regulations
• Flagged contractual anomalies (premium/cover mismatches, non compliant clauses, underwriting errors) and wrote up the findings for the Technical Department
• Cross referenced contract data with the underwriting and claims databases to surface suspicious cases, then flagged them to the fraud team
• Suggested updates to internal procedures and built control checklists that the team now uses day to day

Intern, back end and geospatial development at Tritux (2025-06 – 2025-08)

• Built a full geospatial management system for school transportation (PostgreSQL with PostGIS, NGSI API in Go)
• Created interactive HTML map visualizations for real time spatial analysis
• Automating Excel enrichment with geospatial data cut processing time by 70%
• Integrated over 15,000 filtered OpenStreetMap records to optimize transport routes

Intern, web development at Corail Technologie (2023-06 – 2023-08)

• Built a full weather application in Python/Django REST Framework with responsive interfaces
• Designed UI components for multi city data visualization, keeping visual consistency from one city to the next
• Integrated the OpenWeatherMap API with optimized JSON serialization, the app now handles over 1,000 requests per day

Active member at IEEE Student Branch (2024-09 – Present)

• Winner of the IEEEXtreme Hackathon, Tunisia Section (Oct. 2025)
• Collaborated with IEEE RAS on autonomous robotics and embedded systems projects
• Coorganized 5 technical events and competitions that brought together over 100 students

Computer Science Engineering in specialization in Financial Engineering (4th year) – ESPRIT, École Supérieure Privée d'Ingénierie et de Technologies (2022-09 – 2027-06)
