// Stack
The technology stack, chosen for consequence — not convenience.
Three layers. Each selected because it removes an entire class of failure from the system, not because it trends well.
02
Native Terminals
Zero-bloat cross-platform desktop clients compiled to native binaries. Rust core, system webview, offline by default.
- Tauri v2
- Rust
- IPC Commands
- Auto-Update
Shipped installers under 8 MB — Windows, macOS, Linux
03
Data & State
Deterministic state machines on the client, normalized persistence on the edge. Every mutation is typed, traced, and reversible.
- Redux Toolkit
- SQLite
- Supabase
- Postgres RLS
Row-level policies enforced at the database boundary
// FULL-STACK PIPELINE
End-to-end typed execution. From native core to client runtime.
We engineer vertically integrated systems. From memory-safe database connection pools at the metal, through observable network telemetry, up to strict frontend runtimes—every layer is monitored, typed, and engineered for zero degradation.
// Architectures
Proven architectures, running in production.
Two systems, two entirely different failure domains. Both delivered as sovereign infrastructure the client fully controls.

SouqLink
High-Throughput Industrial B2B Marketplace
A procurement network connecting industrial suppliers to enterprise buyers, handling continuous RFQ traffic with catalogues in the hundreds of thousands of SKUs.
Technical challenge
- Sub - 100ms faceted search across 340k SKUs without a dedicated search cluster.
- Multi - tenant pricing visibility enforced at the row level, never in the client.
- Optimistic RFQ negotiation threads that survive reconnects and partial failures.

QuotationApp
Native Desktop Invoice Terminal
An offline-first quotation and invoicing terminal for field operations. Native binary, local SQLite ledger, deterministic sync when connectivity returns.
Technical challenge
- Full offline authoring with conflict-free reconciliation on reconnect.
- Deterministic PDF generation identical across Windows, macOS and Linux.
- A 7.4 MB signed installer with auto-update, replacing a 180 MB Electron client

// Protocol
The engineering protocol.
Four phases, executed in order, with no phase compressed to hit a demo date. This sequence is the product.
- 01
Architecture Audit
We read the system before we touch it. Data flow, boundaries, latency budgets, and the failure modes nobody documented. Output: a written verdict, not a sales deck.
- Latency Budget
- Risk Register
- 02
System Blueprinting
Schemas, module boundaries, state ownership and deployment topology are settled on paper first. Every interface is decided before the first line of production code exists.
- Schema Contract
- Module Graph
- 03
Zero-Fault Execution
Strict typing end to end, no unowned state, no speculative abstractions. Every merge is reviewed against the blueprint — deviation requires an amendment, not a shortcut.
- Typed Contracts
- Review Gates
- 04
Sovereign Deployment
You own the repository, the pipeline, the database and the signing keys. We hand over an operable system with runbooks — not a dependency on us.
- Runbooks

// Principal
The principal architect.
One accountable engineer on the architecture. No layered account management, no handoff to an unnamed delivery pool.

A foundation in Business Information Systems means the architecture starts from the operational reality of the business — procurement cycles, approval chains, margin calculations — rather than from a framework preference.
That foundation was formalised through an M.Sc. in Software Engineering at Cairo University, with work concentrated on distributed system correctness and the performance characteristics of native application shells.
The result is a narrow practice: high-throughput B2B web platforms and native desktop terminals, engineered to be handed over and operated by the client independently.

Send the constraints. Receive an architecture.
Every engagement opens with a written systems brief — throughput targets, failure budgets, and handover terms defined before a single line is committed.
