Seif Shawky

Data Engineer with 4+ years building production data pipelines and architectures for multi-tenant platforms. Designed per-tenant data isolation and automated schema migrations for an 18-module ERP/LMS serving 40+ school tenants across Egypt and Saudi Arabia, and built real-time, event-driven data pipelines (SignalR + Redis) processing 1M+ events/day with latency cut from 5s to 200ms. Built a RAG-based data ingestion pipeline (Northstar Forge) that ingests PDFs, Word files, websites, and databases with hybrid vector + BM25 retrieval.

Hands-on experience with Apache Spark and Hadoop, SQL/NoSQL databases, and Azure cloud data services.

Data Engineer at Pyramakerz Technologies (2023-01 – Present)

• Data architecture: Designed per-tenant database isolation with dynamic connection strings and automated EF Core schema migrations for an 18-module ERP/LMS, achieving zero cross-tenant data leakage and onboarding new tenants (schools) in under 30 minutes.
• Real-time data pipelines: Built 4 event-driven data pipelines (SignalR hubs for chat, notifications, HR requests, app-state) with a Redis caching layer, cutting end-to-end data latency from 5s to 200ms at 1M+ events/day across 40+ tenants.
• ETL & data processing: Automated Excel-based bulk import/export ETL flows for HR data, cutting processing time by ~50%; built GPS-geofenced attendance data pipelines with device-serial binding for 500+ staff.
• Database performance & warehousing: Tuned ASP.NET Core / EF Core / SQL Server queries (indexing, eager loading, indexed stored procedures), cutting average query/API latency by ~40% under concurrent school-day load.
• Data integration & compliance: Integrated Egyptian ETA and Saudi ZATCA e-invoicing data feeds into the platform's pipelines, extending data compliance to GCC enterprise clients.
• AI data pipeline (Octa): Built a bilingual (Arabic/English) retrieval pipeline embedded in the ERP that indexes and retrieves in-app data, plus golden-dataset evaluation pipelines (recall@10, faithfulness) with full tracing (Langfuse, LangSmith, OpenTelemetry).
• Mentorship: Taught and mentored intern cohorts through complete AI/ML and Frontend Engineering programs.

Data & Flutter Engineer at Blokkah (2024 – 2025)

• Built data-driven geospatial search features (Google Maps spatial search, property filters) for a production Flutter real-estate marketplace, improving listing-data upload performance by ~35%.
