I build production systems end to end, designing scalable APIs and data models, integrating LLMs and AI agents where they earn their place, and shipping live SaaS that real users rely on. I build, secure, and measure what I ship.

// 01. About
Engineering systems that just work
$ cat profile.txt
I'm a backend-leaning software engineer who builds and ships production systems end to end — API design and data modelling, modern frontends in Next.js and TypeScript, and the deployment and security hardening around them.
I deep-dive into system internals — query planners, reverse proxy routing, LLM streaming pipelines — and integrate AI where it earns its place: building tools that are genuinely useful in production, not just impressive in demos.
I ship real products: Orbit, a Professional Relationship OS with OAuth SSO, Gemini AI semantic search, and Stripe billing, runs live at byorbit.io today.
When I'm not building systems, I write on Medium about backend engineering, databases, and infrastructure patterns I've found useful.

Where I've Built Things
Software Engineer / IT Business Analyst
Egyptian Packaging & Plastic Systems Corp
Full-stack engineer and IT systems lead — building internal production tooling and driving data-informed decisions for executive stakeholders.
- ▶Designed and engineered a multi-tenant personal CRM architecture using Next.js 16, React 19, and Supabase, enforcing full data isolation exclusively at the database layer via Postgres Row-Level Security (RLS) to eliminate data-leakage vectors globally
- ▶Developed an interactive, real-time relationship mapping interface utilizing react-force-graph-2d and client-side cache hydration via TanStack Query v5, rendering dynamic D3 force simulations while maintaining instant optimistic UI updates
- ▶Implemented a metered subscription billing system using Stripe webhooks and a custom server-side Postgres usage-metering function (increment_usage), decoupling application logic from critical transaction tracking
- ▶Architected and shipped a multi-entity B2B lead management system that consolidated disparate operational workflows from 4 business units into a single unified platform
- ▶Enforced zero-trust data privacy at the API layer by implementing a 5-layer server-side security stack and field-level Role-Based Access Control (RBAC), ensuring sensitive marketing and sales fields were filtered on the server and never leaked into client network payloads
- ▶Engineered an Egyptian Arabic speech-to-text pipeline by implementing OpenAI Whisper with specialized context priming prompts, significantly reducing Word Error Rate (WER) for colloquial dialects and mixed English/Arabic technical terminology
- ▶Engineered SC 3D Optimizer, a React + Three.js web application that computes optimal container loads via a 3D bin-packing algorithm — delivering real-time 3D visualisations with door-clearance validation, multi-solution comparison, and one-click PDF export for logistics teams
- ▶Built the company's IT Asset Management (ITAM) platform from scratch, designing the data model and lifecycle workflows to centralise hardware and software inventory — eliminating manual tracking gaps and maintenance blind spots across the organisation
- ▶Owned security, reliability, and cost governance for 25+ domains and 7 production websites by implementing automated backups, wp-admin hardening, caching, image compression, and database optimisation
- ▶De-risked capital allocation by delivering cost-benefit and ROI analyses to executive stakeholders, translating business requirements into Power BI dashboards and written executive summaries
- ▶Co-architected the corporate IT department from the ground up — defining governance frameworks, technical role structure, and SOPs for access control, change management, and service delivery — scaling operations to 90+ users
- ▶Automated repetitive IT and reporting workflows with Python scripts, reducing manual overhead and improving consistency across operations
Offensive Security Engineer Intern
WE INNOVATE
Executed white-box and black-box penetration testing across enterprise web, mobile, and infrastructure systems.
- ▶Identified and exploited vulnerabilities in real-world web, mobile, and infrastructure targets against the OWASP Top 10 framework — delivering severity-rated reports with attack-chain documentation and remediation guidance
- ▶Mapped attack surfaces and intercepted traffic using Burp Suite Professional, Metasploit, and Wireshark, demonstrating exploitability with proof-of-concept payloads for client-facing reports
- ▶Ran Active Directory and network penetration tests across enterprise environments, surfacing privilege-escalation paths and lateral-movement risks
- ▶Automated vulnerability scanning and security-testing workflows with Python scripts, reducing repetitive manual steps in the assessment pipeline
Software Engineer
HomeBay Furniture
Built and optimised the e-commerce platform for a Canadian furniture brand, improving site performance and eliminating manual catalogue overhead.
- ▶Engineered responsive e-commerce interfaces for Homebay.ca and extended WooCommerce's product management and checkout flows to meet evolving business requirements
- ▶Improved site performance and user engagement by implementing multi-layer caching, image optimisation, and database tuning
- ▶Built Python automation scripts integrated with the Google Sheets API to synchronise product catalogue data, eliminating manual data-entry overhead from daily operations
- ▶Grew organic search visibility through structured keyword analysis, meta-tag optimisation, and on-page SEO improvements
Software Engineer Intern
Kites Software
Built test-driven RESTful APIs for Egypt's first SaaS ERP in an Agile/Scrum engineering team.
- ▶Shipped production RESTful API endpoints for a Spring Boot SaaS ERP serving Egyptian import and distribution businesses, following a strict test-first (TDD) development workflow
- ▶Wrote Cucumber BDD integration tests against a PostgreSQL backend, catching regression defects before they reached QA
- ▶Investigated and resolved QA-reported bugs, improving release stability and reducing the defect escape rate
- ▶Authored technical onboarding wikis documenting the team's stack and engineering practices, accelerating ramp-up time for incoming engineers
Business Analyst
Tact Decorations
Led the company's first digital transformation — centralising operations and redesigning cross-functional workflows from the ground up.
- ▶Built the company's CRM and operations hub in Notion from scratch, giving site engineers, architects, and supervisors a single platform for project communication, task assignment, and progress tracking
- ▶Redesigned cross-functional workflows to eliminate handoff bottlenecks, improving coordination and reducing delays between field and office teams
- ▶Drove the company's first digital transformation initiative — defining the tooling stack, establishing documentation standards, and producing operational playbooks adopted across departments
Frontend Developer Intern
Information Technology Institute (ITI)
Developed foundational frontend skills through ITI's intensive web development programme.
- ▶Built responsive web interfaces using HTML, CSS, JavaScript, and Bootstrap as part of ITI's structured training programme
- ▶Adopted Git version control and collaborative development workflows from day one
