Aymen Gdhami

I’m a Full Stack Developer with ~4 years of combined experience building and deploying scalable web applications across the entire stack. I’m proficient in Python back-end development and RESTful API design, and I enjoy delivering front-end integration with React—whether in freelance work or personal projects.

In my most recent role, I designed and built a full-stack application with a Python back-end service and an interactive Streamlit front-end dashboard for real-time performance metrics. I integrated RESTful APIs with OpenAI and Azure cloud services, implemented token-based authentication, and put structured error handling and rate-limit management in place to keep production secure.

I focus heavily on data performance, testing discipline, and clean engineering. I designed MySQL database schemas and optimized query layers for a 58K-record dataset using indexing and query tuning, and I applied TDD with full unit and integration test coverage. I also improved system accuracy by 23% and reduced retraining cycles by 20% through iterative back-end pipeline optimization and front-end observability tooling.

Beyond production work, I’ve built automated QA testing suites with Selenium across Python and Java, reducing manual testing effort by 60% and accelerating release cycles. My projects include end-to-end RAG web apps with vector + relational storage, an ML customer segmentation platform with 15% engagement improvement post-launch, and a CCTV multi-stream dashboard processing 8 camera streams at 30 FPS with live alerts—backed by Agile delivery and Git-based collaboration.
