Senior Backend Engineer
Gathern
Feb 2026 – Present
- Growth Team — owns ms-verifications and ms-ai microservices; secondary involvement in ms-search and ms-pricing.
- ms-financial — ZATCA e-Invoicing Compliance (Laravel, AWS)
- • Designed and implemented snapshot-based ZATCA reconciliation supporting credit/debit note generation on reservation
- amendments — capturing the four ZATCA figures at invoice creation and computing per-field deltas to auto-determine note
- type, closing a Saudi tax compliance gap.
- • Resolved a production-blocking 401 in staging caused by ephemeral container filesystem wiping PEM keys; replaced
- file-based reads with environment-aware AWS Secrets Manager resolution with a 300 s cache TTL and Base64/newline
- normalization.
- ms-verifications — Service Ownership (Laravel, Yaqeen)
- • Took full ownership of the identity-verification microservice handling host OTP flows via Yaqeen (Saudi national identity
- provider).
- • Traced and fixed a long-dormant verification popup bug in the Yii2 monolith across 4 years of commit history — popup state
- reset unconditionally on CTA press rather than on actual verification completion.
- • Leading an initiative to migrate all identity-verification logic out of the legacy Yii2 monolith into ms-verifications, reducing
- gathern-joud to pure delegation.
- ms-ai — AI Discovery & MCP Foundation (NestJS/TypeScript, MCP)
- • Architected and shipped Phase 1 of a greenfield NestJS service exposing Gathern's rental inventory to external AI agents
- (ChatGPT, Claude, Perplexity) via a Model Context Protocol server — deployed to staging.
- • Authored the formal technical proposal reviewed by EM and staff engineering, capturing deployment shape, language, auth
- strategy, and agent-commerce standards as formal ADRs.
- • Key decisions: stateless Streamable HTTP transport for horizontal scaling without session affinity; no external OAuth in v1
- (read-only public inventory); Casdoor service JWT for zero-trust internal calls; per-tool TTL caching policy to prevent stale
- availability from causing failed bookings.
