About

Omnichannel commerce platform for a multi-brand retailer on Shopee, Lazada and TikTok.

• Rebuilt an order management system from scratch after the previous vendor shut down; it now handles ~2,500 orders/day and 6,800 SKUs across three marketplaces.
• Owned the inventory engine (stock, reservations, bundles) that keeps stock accurate across channels to prevent overselling, plus the gift-with-purchase and bundle promotions engine.
• Integrated the 3PL warehouse (pick, pack, ship, returns) and settlement reconciliation so finance can match marketplace payouts to orders.
• Set up the team's AI-assisted development process: spec, build, independent AI review, automated test gates.

Workflow automation for business operations, marketing and finance, with 50+ integrations.

• Co-built a new backend workflow executor (Plugin, Code, HTTP, Loop, Conditional, Switch nodes) with real-time SSE streaming and a full audit log, so long-running workflows survive closed tabs.
• Designed a YAML-based plugin engine that generates integrations from any API spec; cut plugin sync across all organizations from ~3 min to ~5 s (60x).
• Built 20+ third-party integrations and a silent OAuth2 re-authentication pattern that became the platform standard.
• Migrated the Stripe billing system as the sole backend engineer and fixed webhook timeouts with async processing.
• Built the backend of a new email marketing product: scheduling, Postmark delivery and tracking, batch sending, AI template generation.

Voice AI inside a customer case-management workflow.

• Integrated LiveKit WebRTC for one-click voice calls with live transcript, sentiment and AI suggestions streamed over a unified SSE endpoint.
• Handled inbound SIP calls via Twilio with webhook-driven caller-to-case matching and an IVR agent for intent triage.
• Built a bilingual (Arabic/English) real-time transcription agent with Azure Speech and Deepgram fallback.

Marketplace connecting car owners and B2B fleets with workshops.

• Built an AI agent that estimates workshop service prices from historical data; cut the prompt from 100K to 16K tokens (−84%) while running accurately on GPT-4o-mini.
• Led GCP cost optimization: −72% on dev instances, −92% on artifact storage, −46% on memory-heavy services, with production utilization kept at 60–70%.
• Refactored the order-management module with DDD and SOLID, fixing a rounding bug that had a top B2B client rejecting invoices; it became the base for four cross-team features.
• Designed and built a multi-tenant garage management system (POS) from scratch as sole developer, with schema-per-tenant isolation and zero-downtime migrations.
• As data engineer: dbt/Snowflake pipelines replacing a month-long manual Excel process, fuzzy-matching cleaning for messy vehicle data, dashboards used by 50+ internal users.

Telemedicine and healthcare automation, backed by a major hospital group.

• Built an RPA project with UiPath that cut document processing time by 60%.
• Integrated Google Cloud Vision into a .NET service to classify PDF, image and Word documents 70% faster.
• Built an admin dashboard in React and Redux used by 100+ internal users.
