SELECTED WORK
Systems built around
real workflows.
These projects go beyond interface design. Each one models operational rules, users, data, transactions, permissions, and day-to-day workflows.

Engineering beyond
the interface.
I focus on the system underneath the screen: domain models, business rules, permissions, data integrity, transactions, APIs, and maintainability.
01
Backend Engineering
REST APIs, authentication, authorization, validation, business logic, transactions, and service architecture.
Node.js · Express · TypeScript02
Data Architecture
Relational data modeling, schema evolution, migrations, constraints, auditability, and data integrity.
PostgreSQL · SQLite03
Operational Systems
Software built around real workflows including POS, inventory, billing, scheduling, purchasing, and reporting.
Business Rules · Workflows04
Full-Stack Applications
Responsive applications connecting practical user interfaces to reliable backend services and data models.
Next.js · React · TypeScript05
Security & Control
Role-based access, authentication, permissions, validation, audit trails, and operational safeguards.
RBAC · JWT · Audit06
System Architecture
Breaking complex requirements into maintainable domains, modules, boundaries, and implementation stages.
Architecture · Domain ModelingHOW I BUILD SOFTWARE
From operational problem
to working system.
I approach projects as systems, not collections of screens.
01
Understand
Study the actual users, workflows, constraints, failure points, and business rules.
02
Model
Translate the operation into domains, entities, relationships, permissions, and system boundaries.
03
Engineer
Build APIs, transactional logic, validation, workflows, interfaces, and integrations.
04
Validate
Test the software against real operational scenarios, edge cases, and failure conditions.
05
Deliver
Prepare the system for practical deployment, maintenance, iteration, and long-term use.

ABOUT
OMAR NOURI build software that solves operational problems.
I'm Omar Nour, a full-stack software developer focused on building practical systems where multiple workflows, users, and datasets need to work together reliably.
My work includes healthcare management platforms, pharmacy systems, retail POS solutions, inventory workflows, billing, scheduling, clinical systems, and data-driven operational dashboards.
I'm particularly interested in the engineering behind the interface: translating real requirements into domain models, database structures, business rules, APIs, permissions, and maintainable software.
Workflow-firstUnderstand the operation before designing the screen.
Data integrityTreat business rules and transactional correctness as core product requirements.
MaintainabilityBuild structures that can evolve instead of accumulating fragile fixes.
