Challenge

Replace manual, error-prone bookkeeping with a real-time, auditable ERP/POS system for SMEs — while meeting Saudi ZATCA Phase 2 e-invoicing requirements.

Engineering Solution

Built a 7-module ERP/POS platform on a self-balancing double-entry accounting engine with native multi-currency accounts and a three-layer audit trail, plus ZATCA Phase 2 compliance via automated and manual XAdES-signed transmission paths.

Key Result

Delivered a cohesive 7-module ERP/POS system with guaranteed trial-balance equilibrium and full ZATCA Phase 2 compliance — 100% cloud, zero installation.

Challenge

Give non-technical users a way to launch a professional, fully responsive website in minutes — with real branding control, ongoing content management, and bilingual (AR/EN) support.

Engineering Solution

Built a modular template engine (30+ responsive templates) with automated site provisioning, a built-in CMS, a live theming layer, bilingual delivery, and an automated account-lifecycle system for subscription expiration and data retention.

Key Result

Delivered a self-service platform taking users from template selection to a live, bilingual website in under 5 minutes — zero code, zero manual provisioning.

Challenge

Long documentation was hard to search and a general LLM would hallucinate answers instead of admitting it didn't know — with no escalation path for unresolved queries after hours.

Engineering Solution

Built two n8n pipelines: one chunks and embeds documentation into Supabase/pgvector, the other runs a LangChain RAG chain over GPT-4o-mini for grounded, source-cited answers, escalating unresolved queries to Microsoft Teams.

Key Result

Delivered a zero-hallucination, source-cited support chatbot with 24/7 coverage and automated human escalation for every unresolved query.

Challenge

Give users of a full ERP/POS system instant answers to financial questions in natural Arabic or English — without ever showing generated numbers or data the requesting user isn't already permitted to see.

Engineering Solution

Built a conversational layer using semantic intent matching and LLM tool calling to run real, permission-filtered queries against the tenant's live database, with a documentation-grounded knowledge base for "how do I...?" questions and short-term conversation memory.

Key Result

Delivered a financial assistant with zero elevated access, live data-backed answers, and full usage-cost visibility for administrators.

Challenge

Sales reps were manually scrolling LinkedIn for buying-intent signals across 5 GCC markets, with no systematic way to enrich contacts or keep the CRM up to date.

Engineering Solution

Built an n8n pipeline that discovers bilingual intent posts, enriches contact data via a B2B API, scores and drafts outreach with GPT-4o-mini, and delivers 5 one-click sales actions inside a Microsoft Teams card synced to HubSpot.

Key Result

Delivered a zero-touch prospecting pipeline across 5 GCC markets with 7 integrated platforms and full analytics on lead volume and conversion.
