Who I Am

About Mohammed Al-Omari

I'm Mohammed Al-Omari a Backend Software Engineer based in Amman, Jordan, currently building scalable server-side systems at Mobasher Auctions. My core focus is on designing APIs that can grow without becoming a maintenance burden — clean architecture, typed all the way down with TypeScript, and deployed reliably with Docker.

What sets me apart is my investment in workflow automation. I use n8n to bridge system gaps that would otherwise require custom glue code — turning hours of manual work into auditable, resumable pipelines. When I look at a business process, I'm always asking: where is human time being wasted on something a machine could handle?

On the side, I maintain M.GAMES—13 vanilla JS browser builds that keep my frontend instincts sharp.

I hold a BSc in Software Engineering from Jordan University of Science and Technology (GPA: 3.46), and I continuously expand through structured learning — from backend architecture deep-dives to accessibility and performance coursework.

What I Do

Technical Expertise

A full-stack toolkit weighted heavily toward backend systems, data, and automation.

Backend Engineering

Designing resilient, modular server-side applications with NestJS and Express.js — structured, typed, and built to scale.

Workflow Automation

Engineering n8n pipelines that eliminate manual overhead and connect disparate systems — without writing brittle glue code.

Data Engineering

Modeling schemas for correctness and querying for performance — relational and document stores, with TypeORM as the bridge.

Frontend Development

Building accessible, performant UIs in React and Vanilla JS — with an eye on Core Web Vitals and cross-platform consistency.

What I've Built

Projects

Production-minded builds — not just tutorials.

@Injectable()
export class JiraSyncService {
  async trigger(event: string) {
    await this.n8n.post(event);
  }
}

TypeScript

Event-driven NestJS service that decouples Jira API orchestration from backend domain logic entirely. The backend owns product data in MySQL; n8n owns every Jira interaction. Includes bidirectional sync via webhooks, API key auth, Helmet, rate limiting, Pino structured logging, TypeORM migrations, and a full deployment checklist.

@EventsHandler(OrderCreated)
export class OrderHandler {
  handle(e: OrderCreated) {
    this.emit('order.process');
  }
}

TypeScript

Production-ready NestJS backend that moves beyond basic CRUD to demonstrate reliable, event-driven architecture for real-world order processing. Built to handle state transitions, domain events, and failure resilience patterns.

Vanilla JS, zero frameworks

I build backends for work. I build browser games in vanilla JS to stress-test logic, animation, and performance—the same way I stress-test APIs. Thirteen builds: Wordle, Tetris, Tower, Connect 4, and more.
