Freelancer Overview

Senior Backend Software Engineer with 3+ years of experience building production fintech systems in Python/Django and PostgreSQL. Currently engineering settlement claims and credit infrastructure at a fast-growing fintech, where I design schemas, build REST APIs, and own services from data model to deployment. My strongest domains are financial systems (credit reports, loan management, settlements, fraud detection, eKYC onboarding), backend architecture (Django/DRF, clean architecture, REST API design), and data engineering (advanced PostgreSQL administration, complex SQL with window functions and CTEs, MongoDB, DuckDB). I have hands-on DevOps experience with Docker, Jenkins CI/CD, systemd, and Linux server administration. I write production-ready code with strong attention to correctness, edge cases, and static analysis. I'm comfortable reviewing, debugging, and improving code across the full backend stack, and I can clearly explain technical reasoning in writing whether for incident response, architecture decisions, or training data annotation. Education includes Bachelor of Science, Faculty of Computers and Artificial Intelligence, Cairo University (2023). Well suited for text-focused AI training, including legal document review, compliance annotation, and rubric-based quality evaluation.
