02WHAT I DO

1. A

   Full-Stack Development

   I don’t stop at the interface. The work isn’t done until the API, data, and payment flow work too.

   • ARCHITECTUREsocket to pixel: 4 roles, one database
   • INTEGRATIONPayTR payments signed in an edge function
   • MEASUREMENT6 developers, one Postgres, 5 × 2-week sprints
2. B

   AI Agent Engineering

   A chatbot that answers well is the easy part. I want the agent to find context, touch the system, and check the result.

   • ARCHITECTUREadvice → XML-RPC → live Odoo 19
   • INTEGRATIONOdoo 19 · GPT-4o-mini · Iyzico
   • MEASUREMENTprecision/recall 0.60–0.70 → 0.85–0.95, 15 regression tests
3. C

   Product & Backend Architecture

   Feeds drop, callbacks arrive late, and jobs stop halfway. I design as if none of that is exceptional.

   • ARCHITECTUREcache first: 60s TTL, 24h stale copy
   • INTEGRATIONthree feeds, one precedence rule; failed LLM → Redis retry (max 2)
   • MEASUREMENTinsight refresh 15s → 3s, ~14ms NLP per article
