What I'm looking for

I'm looking for an opportunity where I can build and govern production AI systems, own architecture and delivery decisions, and work with teams that value explicit engineering standards, validation, observability, and safe release processes.

I've built production platforms for PulseDataLab's U.S. fashion startup client, taking an API-first Drupal 11 architecture from design to production in under six months with release gates, observability, and 80%+ automated test coverage.

I design applied AI systems that use RAG for changing knowledge, parameter-efficient adaptation for repeatable behavior, and deterministic validation for safe releases. For Montessori Kids Learning Games, I built a writer-to-adjudicator workflow supporting 2,500+ learning experiences across 10 released languages while keeping every production change reviewable and rollback-ready.

Across Turkcell, Limestone Digital, FCB Health Reaktor, and earlier product teams, I've owned architecture, Python data pipelines, APIs, cloud operations, incident response, testing, and technical handover.

Chose an API-first Drupal 11 architecture and explicit service/data contracts to decouple React Native and back-end delivery; shipped the platform in under six months with event-driven workflows, monitoring and controlled releases. Built Python/Pandas/NumPy crawling and ingestion jobs for QA and product validation; normalized and deduplicated web/API/CSV data, then protected AWS transfers with mul
