Khalid

AI Engineer

I build production AI systems — LLM pipelines, distributed backends, real deployments on GCP. Not notebooks. Not demos. Things that run under load and stay up.

Things I've shipped

Production systems with real users and real load — not portfolio demos.

Production

Selfimoji

AI image & video generation platform for iOS. Users generate personalised photos with preset backgrounds, create video ads, try on clothes virtually, and share via a custom WhatsApp keyboard — all powered by per-feature AI pipelines I built from scratch.

Per-feature AI pipelines Distributed job queue Apple IAP backend WhatsApp keyboard UGC — image & video Virtual clothes try-on

Designed a distributed job system with retry logic, idempotency, and locking so concurrent AI generation tasks never lose state. Handled full GCP deployment with IaC and automated CI/CD from day one.

Production

AI Email Sequencing

LLM-powered outreach system deployed in production. Reduced manual email effort by 90%. Handles sequencing logic, personalisation, and delivery — all driven by LLM APIs.

90% less manual outreach effort Full idempotency & retry logic Automated GCP deployment LLM-driven personalisation

Built with full idempotency, retry logic, and automated CI/CD on GCP Cloud Run — handles failures gracefully and never sends duplicate emails under load.

Let's build
something real.

Open to remote freelance projects and full-time roles at ambitious companies. If you need AI systems that work in production — not just in a notebook — let's talk.
