Khalifa G.

• Leading frontend architecture and delivery for Yassir's admin platform (~7,800 orders/day).
• Designed and built a Module Federation microfrontend architecture (shell + 12 independently deployable remotes) replacing 36 server-rendered AngularJS instances, eliminating all frontend server instances and decoupling squad deployment cycles.
• Identified a $61k/year silent payment-capture failure (1,149 unreconciled orders to date) on auth-then-capture flows (Stripe, Peach, Payzone, hybrid wallet+card); cross-validated 33 silent-loss orders in MongoDB against 34 error spans in Datadog APM, traced root cause to three independently broken alerting/reconciliation contracts, and proposed both short-term (reconciliation cron) and long-term (queue-backed payment dispatch) remediation paths.
• Owned 6 out of 10 major admin modules in a dashboard revamp taskforce (team of 4), replacing a legacy dashboard built over 7 years.
• Designed a unified Food Aggregator integration (Grubtech, Lacassia, Cassia Manager) driving ~20,000 new orders.
• Leveraging AI-assisted development (Claude Code, Cursor, Codex) across the full engineering workflow.

• Senior Full-Stack Engineer on the Yassir admin platform, contributing to the revamp of legacy systems and development of new features for operations, restaurant management, and delivery workflows.
• Built and maintained core admin modules using React 19, Vite, and Zustand within a microfrontend architecture.
• Contributed to the food ordering and delivery platform's operational tools used by internal teams managing ~7,800 daily orders.
• Collaborated with cross-functional squads on feature delivery, code quality improvements, and mentoring junior and mid-level engineers.
