Building a Python-based retrieval pipeline for Turkish legislation, constitutional provisions, court decisions, and other legal sources, embedding and storing the corpus in Supabase/pgvector.  Implemented case-aware retrieval and context construction so Claude/GPT receive the most relevant legal material for the active matter instead of a generic knowledge dump.  Designing the assistant as an agentic workflow: tool use, MCP integrations, case context, user follow-up, and failure handling are part of the system rather than separate add-ons.  Using AI evaluation/testing and observability to inspect retrieval and model behavior, with local-model experiments and smallscale fine-tuning work used to explore quality and system trade-offs

Architected and shipped a cross-platform AI product released on Apple App Store and Google Play across international markets.  Integrated OpenAI and Anthropic across five AI features, designing prompts, context flows, and personalized responses around user-specific data and product state.  Built production LLM workflows with validation, failure handling, retries/fallbacks, and observability around model interactions so AI behavior could be diagnosed after release.  Resolved an App Store 4.3 policy rejection, rebranded and relaunched the product with expanded functionality within one week; also migrated subscriptions from RevenueCat to Adapty
