SOFTWARE ENGINEERING / RESEARCH DATA
I'm Saeed Hatami. I build applications and interfaces that make research data and metadata reliably accessible, validatable and publishable.
Full-Stack Engineering · Cologne, Germany
Technical depth, with a commitment to keeping software understandable and useful over time.
01 / AREAS OF WORK
From research infrastructure to business processes: translating domain requirements into reliable software.
Validation, conversion and publication of metadata through stable APIs. DOI and DataCite workflows connect domain rules with reusable data.
Clear boundaries between domain logic, interfaces and presentation; automated tests for mapping, validation and registration.
Web applications for personnel, administration, inventory, accounting and hotel operations. Roles and permissions, data models and clear workflows make complex processes manageable.
Separated backend and frontend structures; unit, feature and UI tests cover domain rules, access control and mobile workflows.
Structuring components, forms, data access and integrations so new features can be built consistently and existing systems can evolve.
Replaceable data sources, strict typing, localized interfaces and quality gates with Jest, Playwright and CI.
Toolchains for model-based testing of embedded systems in automotive and aerospace; modeling and automation with MATLAB/Simulink.
02 / CAREER
Development, architecture and integration across different technical domains.
Full-Stack Developer · Research Data & Metadata Publishing
Responsible for designing and evolving web applications that capture, validate and publish research data and metadata. I develop APIs and DOI/DataCite workflows, shape testable components using Hexagonal and Clean Architecture, and refine requirements with domain experts in a Scrum team.
Full-Stack & Metadata Solutions
Design and development of custom web applications and management systems for HR, administration, inventory, accounting and hospitality. Work includes user interfaces, data models, roles and permissions, business workflows and API integrations.
Web Developer
Development of mobile interfaces and web services for the university mobile app and LSF campus management. Responsible for SOAP interfaces and integrations with Moodle and Typo3.

04 / ABOUT
I work where domain requirements, data and software architecture meet.
My focus is on making research data discoverable and reusable through reliable interfaces following FAIR principles — including as a basis for AI-supported analysis. I work closely with researchers and use architecture principles where they improve testability, maintainability and a system's ability to evolve.
My approach: model domain rules explicitly, keep components clearly separated, and cover critical paths with unit, API and end-to-end tests.
