Magical Digits
Full Stack Engineer
Platform consolidation: Replaced all independent ASP.NET codebases with a unified .NET 6 API and Next.js front end serving all brands from one multi-tenant backend.
Content architecture: Designed a SQL Server–driven dynamic page and routing model, removing per-property release cycles entirely.
High-traffic migration: Transitioned OTA and direct booking flows (peak: thousands/day) with full availability, pricing, and transactional reliability maintained throughout.
Availability: Kept the consolidated platform within four- to five-nines targets—99.99%+ to 99.999% annual uptime on booking and OTA integration surfaces.
Performance: ~60% reduction in bespoke markup via shared templating; p95 API latency improved ~40% on checkout paths.

2025 - Present Full Stack Engineer
iClosed.ioKey contributions include:
- Built iClosed's public API platform — OAuth 2.0, rate limiting, versioned OpenAPI/Swagger docs, and an MCP server — now serving 10,000+ partners and processing 1M+ API requests/week for secure, agent-native integrations.
- Integrated device fingerprinting into the booking pipeline, eliminating spam — one customer saw thousands of fraudulent bookings (IP-rotation-based) drop to zero post-rollout.
- Built AWS CloudFront–based OG link previews (the rich cards that appear when sharing links on Slack, Twitter, etc.) across 10,000+ events and 1M+ bookings, improving SEO discoverability — no extra infrastructure required.

2025 - Present Founder & Full Stack Engineer
CastTurn any API into a production, agent-ready MCP server — no OAuth/DCR work required. Key contributions include:
- Spec-to-server pipeline: Built the full flow that turns any OpenAPI/Swagger spec into a hosted MCP server in minutes — auto-generating tool definitions and endpoints, then provisioning isolated servers on AWS ECS.
- Real-time analytics suite: Shipped a unified dashboard across all of a customer's MCP servers — tool-call logs, latency, error monitoring by status code, top tools, request health, and geographic demographics.
- Pattern Intelligence: Engineered sequence mining that detects common tool-call chains and auto-suggests reusable agent SKILL.md workflows (e.g. an Order Lookup Flow at 94% confidence).
- Granular governance: Per-tool enable/disable plus scope and custom-parameter injection at both workspace and tool level, and a custom-domains system with automated ACM cert validation and ALB host-header routing.
- Hardened for multi-tenant scale: AES-256-GCM secret encryption, Redis-backed distributed rate limiting (fail-open), soft-delete lifecycle, and plan-gated billing.
MCP
2024 - Present INDEPENDENT PROJECT
Key contributions include:
- Low-code data plane: Shipped a 3-step merchant flow (connect → map fields → automate) so non-developers wire Zid to Sheets in minutes instead of custom scripts.
- Entity coverage: Built exports for 4 operational domains—orders, customers, carts, and product catalog—into user-selected workbooks with column-level mapping.
- Sync modes: Combined secure webhooks with on-demand pulls so teams can run 3 complementary paths—manual export, scheduled jobs, and event-driven pushes—from one configuration surface.
- Localization: Delivered 2 full UI locales (English + Arabic) including RTL layout, aimed at MENA operators on Zid.
