Work Experience

AI & Analytical Engineer at WeTrackAds

September 1, 2024 - Present

Designed and automated ETL Pipelines (BigQuery, dbt, Airflow) to unify marketing data from Google Ads, Meta Ads, and TikTok Ads, improving data accuracy and reducing reporting latency. Developed machine learning models (Python, scikit-learn, XGBoost) to predict conversion likelihood and optimize audience targeting, leading to smarter ad spend allocation. Built ad spend optimization workflows using Google Ads & Meta APIs to automatically adjust bids, budgets, and targeting parameters, reducing manual intervention by >30%. Implemented real-time anomaly detection for KPIs (CTR, CPC, ROI) with Python & Airflow, triggering automated alerts via Slack to ensure rapid response to underperforming campaigns. Partnered with marketing strategists to run automated A/B testing pipelines (Vertex AI, BigQuery ML), cutting experiment cycle time and accelerating data-driven decision making.

Software Developer at First Abu Dhabi Bank

January 1, 2021 - Present

Built a CRUD API for a storage server using MinIO, supporting file upload, retrieval, and deletion functionalities. Integrated authentication and authorization features into APIs to ensure secure operations and data protection. Implemented RBAC to manage user permissions securely and ensure resource access aligned with roles. Developed a microservices-based QR code application for encoding and decoding, focusing on modularity and scalability. Designed health check endpoints and implemented detailed logging for API health monitoring. Rewrote legacy Java (SpringBoot) and JavaScript code into TypeScript, improving maintainability, type safety, and scalability of the application. Ensured code quality and reliability through unit testing frameworks like Jest, delivering robust and maintainable systems.
