01 — Profile

Engineering
with purpose.

A product-oriented developer who connects technical precision with genuine business value — from mobile UX to backend architecture to automated deployment.

Background
Baghdad Mohamed (Mohamed Baghdad) - Backend & Mobile Developer
Mohamed
Baghdad.

Hi, I'm Mohamed Baghdad. I have a backend-first mindset and strong architecture thinking. Before writing a single line of code, I architect scalable systems and define strict APIs.

While my core identity is in backend engineering and database design, I deliver end-to-end applications across Android and Full Stack when needed. My work spans from complex mobile apps to high-traffic SaaS products.

Featured
Projects.

Four production-grade products built to solve distinct real-world business problems — from award-winning mobile apps to multi-tenant SaaS platforms.

01 — NutriSafe
★ Hackathon Award Winner

NutriSafe

Android Application — Allergy Safety Scanner

Problem: Food allergy sufferers unknowingly consume dangerous ingredients due to confusing nutritional labels.

Solution: Designed scalable API endpoints, local database synchronization logic, and robust offline fallback architecture to support real-time scanning.

Results: 3rd Place Hackathon Winner. Handled complex OCR dataset parsing securely with sub-second API latency.

02 — Coffee Shop Loyalty
Full-Stack CRM · 2024

Coffee Shop Loyalty System

Laravel · MySQL · RBAC · REST API · GitHub Actions

Problem: Independent cafes lose customers because centralized loyalty & reward ecosystem providers are too expensive.

Solution: Architected a multi-tenant backend with JWT auth, role-based access control, and strict database integrity for atomic point transactions.

Results: Zero transactional failures. Delivered a highly cohesive API ensuring accurate synchronization across a cross-shop loyalty network.

03 — Scalable POS
Enterprise Backend · 2024

Scalable POS System

Laravel · MySQL · RBAC · Optimized Queries

Problem: Opticians rely on fragmented legacy software to manage critical medical prescriptions and optical stock.

Solution: Engineered an enterprise backend focusing on high-performance database indexing, relational modeling, and strict RBAC filters.

Results: Scaled to thousands of active SKUs. Reduced complex relational query times by 40% through strict backend optimization.

04 — Car Renting
Android Enterprise · 2023

Enterprise Car Renting

Java · Android · Firebase · Retrofit · SQLite

Problem: Field agents face lost contracts and corrupted app states due to patchy internet connections outdoors.

Solution: Managed complex error handling and synchronization logic by pairing robust local database operations with delayed remote API commits.

Results: Eradicated sync failures, proving system resilience when buffering high-value transactions during connectivity drops.

04 — Methodology

How I
Work.

A structured, repeatable process from discovery to deployment. Organized, communicative, and shipping with intention.

01
Discovery

Define the real problem. Understand users, workflows, and constraints before touching code.

Requirements · Scope · Feasibility
02
Architecture

Design the system — data models, API contracts, component boundaries, deployment strategy.

Schema · API Design · Stack Choice
03
Development

Iterative builds. Meaningful commits. Modular code. CI runs on every push to main.

TDD · Feature Branches · Code Review
04
Testing

Unit tests, integration checks, edge case coverage. Automated pipelines validate every build.

Unit · Integration · Regression
05
Delivery

Deployed via pipeline. Structured handoff, README docs, and post-launch monitoring.

Deploy · Docs · Support
05 — Standards

Engineering
Discipline.

Code quality isn't a bonus — it's the baseline. Every project ships with CI, clean architecture, and documentation.

01
Version Control Discipline

Semantic commits, feature branch strategy, pull request reviews. Every repo tells a clean story of how the product evolved.

02
CI/CD via GitHub Actions

Automated test → build → deploy pipeline on every push. No manual releases. No "works on my machine."

03
MVVM & Clean Architecture

Presentation, domain, and data layers kept strictly separate. ViewModels that don't know about Views. Repositories that don't know about UI.

04
Documentation as a Deliverable

READMEs, API endpoint docs, inline comments, and architecture diagrams. Every project is understandable by any engineer, not just me.
