Software Architect & Senior Software Engineer

Dr. Alex El-Shaikh

I design and build scalable backend systems from architecture to delivery, combining Java/Spring Boot engineering, AWS cloud services, database systems, and technical project coordination. Based in Frankfurt am Main, Germany.

Backend architecture with research depth

  • PhD-trained computer scientist with 7+ years in scalable, data-intensive systems
  • Production experience across Java, Spring Boot, AWS, relational databases, and REST APIs
  • Comfortable translating complex requirements into robust architecture and aligned delivery

What I Bring

Architecture, data, and delivery

Minimal backend architecture visual with cloud, service stack, and API endpoint Systems

Scalable backend architecture

Java/Spring Boot services, REST APIs, cloud integrations, batch processing, and maintainable modular design.

Minimal database visual with a central data store and simple pipeline elements Data

Database-heavy applications

Relational and NoSQL systems, ETL pipelines, query optimization, indexing, and TB-scale research data.

Minimal delivery coordination visual with blueprint and task tiles Delivery

Technical coordination

Requirements analysis, architecture decisions, code reviews, mentoring, and Scrum/Kanban collaboration.

Minimal DNA data storage visual with helix and data cube Research

Product-minded research depth

DNA data storage, distributed systems, scientific software, and translating complex domains into usable systems.
