I am a Data & AI Engineer with a foundation in Computer Engineering and Data Science. I am personally driven by curiosity and the challenge of turning bold ideas into reliable working systems. I build solutions using strong software engineering principles, focusing on modular design, automation, testing, version control, CI/CD, traceability, and reproducibility to create systems that are easier to maintain and evolve.
My work brings together data engineering, analytics, machine learning, cloud infrastructure, and automation to deliver reliable, scalable solutions for real-world use. I enjoy connecting cloud-native data platforms, AI applications, deployment pipelines, and observability into cohesive, well-integrated systems.
My experience across healthcare, media, and research has shaped my philosophy: build quickly, learn continuously, and always keep user impact at the center. The best technology is defined not by complexity, but by its usefulness and trustworthiness.
In my free time, I enjoy puzzle games, sports, and hackathons. These activities sharpen my problem-solving skills and keep me well-rounded.

Building solutions that make a difference
• Deployed and managed production data pipelines on AWS and Snowflake, processing 25M+ daily records across 14 brands and 4 Swiss operators, enabling executive KPI reporting and subscriber analytics
• Designed a self-healing data monitoring system with automated data gap detection, retry logic, and escalation alerts, replacing a manual daily monitoring process for four operators
• Automated the BCE executive board reporting pipeline across eight European markets, implementing daily data integrity checks that replaced a manual weekly reporting process
• Investigated and recovered a failed customer care data pipeline, backfilled historical data across 11 brands, and replaced a Power BI dashboard with a Next.js/TypeScript application deployed on Google Cloud Run with GitHub Actions CI/CD
• Designed data ingestion pipelines for a retrieval-augmented fact-checking platform using automated web scraping and dataset curation across multiple trusted news sources
• Built retrieval-ready datasets and backend retrieval workflows supporting LLM-assisted fact verification and response generation
• Developed backend services and retrieval pipelines using Python and LangChain to support the ChatJourno MVP
• Presented the platform's technical implementation and outcomes at the 2024 Media Innovation West Africa Conference
• Led healthcare data migration and standardization for an Electronic Medical Records (EMR) deployment across two hospitals, covering clinical records, pricing structures, service catalogs, and user accounts
• Coordinated cross-functional delivery using Agile methodologies, trained 100+ healthcare professionals, and reduced post-deployment support issues by 70%
• Led a research programme on out-of-school children, overseeing data collection, statistical analysis, and impact reporting that enabled the enrollment and sponsorship of 30 students
• Coordinated multi-stakeholder research initiatives, project planning, and policy evaluations across a two-year programme
