Alex Seif

Freelance Software Engineer & Systems Architect

Provide requirements elicitation, full-stack development, database optimization, AI systems integration, devops automation, and infrastructure management for commercial enterprises, digital media agencies, and state public institutions.

AI & Data Pipeline Implementations:

• Production Agentic Workflow Engineering: Designed and deployed autonomous text-scraping and system-monitoring topologies using LangGraph. Implemented append-only state channels via operator.add data reducers and persistent SQLite/PostgreSQL checkpointers, ensuring state safety and eliminating memory leaks across cyclic multi-worker execution loops.
• Enterprise RAG Pipeline Architecture: Engineered document ingestion pipelines to transform unstructured historical records into structured, queryable knowledge archives. Developed semantic text chunking algorithms with overlapping character windows and configured localized vector storage engines to map text embeddings alongside relational metadata tags.
• Ajel.sa (Mass Media Network): Served as Technical Partner for 2–3 years managing the infrastructure for the #2 news outlet in Saudi Arabia. Maintained a hyper-scale enterprise Drupal environment hosted on Acquia Cloud, implementing Varnish edge caching and optimizing relational indexes to absorb traffic spikes during major breaking news cycles. Managed automated, asynchronous background ingestion pipelines to pull and parse content feeds from global networks like the BBC.

Public Sector & Sovereign Infrastructures:

• Egyptian Ministry of Interior (MOI) - Traffic & Aman Portal: Architected a customized enterprise Drupal infrastructure and high-concurrency routing engine to schedule services across facilities and mobile units, servicing a population scale of 40M+ citizens.
• MOI Egypt Blind Deployment Execution: Built automated shell scripts to run complex Git path updates, dependency updates, and database schema migrations seamlessly on air-gapped intranet networks without direct developer access.
• Saudi Standards, Metrology and Quality Organization (SASO PTI): Led a 3-year migration of a monolithic enterprise Drupal portal into a highly available Headless architecture. Built state-preservation and fail-safe queue mechanics to handle data payloads securely during external transaction timeouts.
• Dubai Police Department - Enterprise Training Network: Configured compliance workflow engines and background tracking loops inside an isolated government cloud environment to monitor student progress.
• Salama Portal (KSA): Engineered a state-subsidized cooperative insurance gateway using Drupal Enterprise CMS, deploying a high-concurrency transaction engine and secure data exchange layers to synchronize policy classifications with national enforcement agencies.

Commercial & E-Commerce Implementations:

• Agazat Masr (Tourico): Co-engineered a custom dynamic travel package assembly catalog and transaction engine. Built an asynchronous, email-driven booking queue that scaled the client to become a leading domestic tourism provider in Egypt, maintaining database integrity during intense search concurrent load. Supported and upgraded the codebase continuously for 3 consecutive years.
• Esorus Ecosystem: Designed a highly scalable database schema using Symfony to pivot a design content platform into a commercial B2B marketplace, indexing 15,800+ products, 1,200+ architects, and 300+ suppliers.
• Desoky & Soda: Built decoupled backend structures and high-elasticity relational schemas using the Symfony framework to support database modifications during agile sprint cycles.
• Svelto: Deployed a decoupled product personalization and print configuration engine utilizing an optimized WordPress and WooCommerce core architecture, handling secure payment gateway loops and asynchronous webhook hooks.
• Misfits LLC: Architected a lightweight web catalog resulting in 6+ consecutive years of zero-maintenance uptime with zero code edits or structural patches required post-deployment.
• North South Consultants Exchange (NSCE): Normalized fragmented, multi-lingual database models and built indexed custom taxonomies and geospatial mapping systems for international donor projects (UN, GIZ, EU).
• bndko.com: Deployed a custom mobile-first front-end layout optimized for low SpeedIndex scores, connecting asynchronous form capture hooks directly to background outbound email marketing automation suites.
• Alexander Restaurant: Deployed a zero-bloat digital interface using custom lightweight base themes, optimizing asset compression and mobile caching layers for instantaneous page execution.

Co-Founder & Chief Technology Officer (CTO)

Managed backend software engineering, transaction processing pipelines, and cloud security compliance for a high-volume travel ticketing application.

• Core Ledger Scaling: Engineered the backend asynchronous transaction routing systems that successfully processed over 33% of all domestic air travel ticketing throughput nationwide across Egypt.
• State Machine Hardening: Built a defensive transactional state machine that safely cached, retried, and committed atomic financial ledger updates during banking gateway or network dropouts.
• Security & Auditing: Engineered data-at-rest encryption pipelines and multi-region tokenization frameworks to pass strict security audits and achieve full PCI-DSS compliance verification using Test-Driven Development (TDD) and Behavior-Driven Development (BDD).

Contracted Web Developer & Systems Analyst

Executed full-stack web application development, custom coding, framework migrations, and local server management for regional businesses.

• Bouri Center (Legacy ERP Integration): Modeled and decoupled an e-commerce database to function independently as an isolated branch node, bypassing uncooperative legacy corporate ERP blocks. Built an ingestion gateway to sanitize corrupt vendor data streams before web production deployment.
• Resort Choice (Multi-Tenant Yield Engine): Codified rental contract terms into validation logic within custom database views to enforce linear booking limits and completely prevent cross-channel double-booking race conditions.
• Infrastructure Custody: Took complete ownership of bare-metal server configurations, localized staging builds, automated deployment tasks, and disaster recovery (DR) protocols.
• Egyptolution (Custom Media Portal): Built a high-velocity custom MVC blogging engine utilizing clean JavaScript and layout parameters optimized for quick page loads and smooth media delivery to showcase hotel and tourism client portfolios across Egypt.
