01. About Me

Senior Backend Software Engineer with 6+ years of experience building scalable, cloud-native platforms and modernizing enterprise systems.

I specialize in Java/Spring Boot microservices, distributed systems, and legacy modernization — including leading large-scale migrations of 30-year-old desktop systems into modern cloud-native SaaS platforms.

I'm a German national currently based in Egypt, working 100% remotely for a company in Böblingen, Germany. Fully aligned with German work culture, time zones, and fluent in German at C1 level.

Beyond coding, I enjoy mentoring engineers through structured code reviews, microservice design workshops, and hands-on knowledge sharing.

  • Leading large-scale migration of a 30-year-old legacy Uniface desktop system into a cloud-native, multi-tenant SaaS platform built on microservices architecture.
  • Decoupled core business modules (Mail, Payment) by migrating logic from Uniface to Spring Boot microservices backed by Microsoft SQL Server and Oracle, exposing RESTful APIs to a modern thin-client frontend.
  • Engineered cross-tenant database schema compatibility strategies for SQL Server and Oracle, ensuring forward/backward compatibility across phased rollouts.
  • Built a custom Uniface code-parsing and refactoring engine that automates syntax modernization, cutting manual migration effort by ~65% and significantly reducing regression risk.
  • Integrated AI-assisted development workflows using Claude Code, OpenCode, GitHub Copilot, Model Context Protocol (MCP), and Retrieval-Augmented Generation (RAG) to accelerate legacy code analysis, knowledge retrieval, and migration automation.
  • Designed and deployed n8n-based automated workflows to streamline repetitive operational tasks and inter-service orchestration, reducing manual intervention across the migration pipeline.
  • Mentored junior engineers through structured code reviews, microservice design workshops, and hands-on knowledge sharing.
