Experience

• Backend Engineer · MTN04-01-2025

  • Built an AI audience segmentation engine from scratch using NLP and LLM fine-tuning. This automated our targeting process and led to a 25% bump in campaign conversions. • Rewrote high-latency parts of our URL shortening and analytics services in Rust. This cut our memory usage by 40% and allowed the system to handle over 1M concurrent requests during heavy traffic spikes. • Set up automated MLOps pipelines on AWS to manage model retraining. I focused on making the AI's logic transparent (XAI) so stakeholders could understand why certain segments were being targeted. • Led the move from a monolith to microservices designed specifically to handle AI workloads. Used RabbitMQ for messaging and Redis to keep data retrieval fast.

• Software Developer · Qfremit - Contract09-01-2023 – 01-01-2024

  •Built a flexible payment platform supporting both currency conversion and remittance with configurable pricing models. •Integrated real-time currency exchange APIs to enable accurate international transaction processing. •Implemented multi-provider payment redundancy to ensure service reliability and minimize transaction failures.
