Microsoft Türkiye project · Local development

QueryPilot Local

An offline-first PostgreSQL execution-plan assistant with read-only SQL controls, recursive EXPLAIN JSON analysis, deterministic diagnostics, and Foundry Local retrieval.

  • 24 citation-ready knowledge chunks
  • 3s database statement timeout
Collaborative backend system · Active development

SupportFlow AI

A multi-tenant support backend with transactional ticket workflows, append-only audit events, and retry-safe document ingestion.

  • 187 test cases
  • Tenant-scoped data access

Professional journey

Experience

Production-minded work across backend AI systems, retrieval-augmented applications, and enterprise software engineering.

Back-End AI Engineering Intern (Remote)

FlyRank.ai

Jul 2026 – Sep 2026

Usage Metering & Billing Engine

  • Built a PostgreSQL-first multi-tenant usage metering and billing service with FastAPI, SQLAlchemy, Alembic, monthly quotas, exact integer micro-USD pricing, durable alert jobs, and signature-verified Stripe test-mode subscription synchronization.
  • Hardened retry, concurrency, and webhook correctness with idempotency keys, PostgreSQL advisory locks, payload fingerprinting, event-order guards, and tenant isolation. Verified that 12 concurrent usage retries produced exactly 1 persisted event and 8 concurrent webhook deliveries produced exactly 1 applied event across a 22-test PostgreSQL suite.

AI Innovators Summer Internship (Remote)

Microsoft Türkiye

Jun 2026 – Jul 2026

QueryPilot — Evidence-First PostgreSQL Performance Assistant

  • Built and released an evidence-first PostgreSQL performance assistant combining deterministic EXPLAIN-plan diagnostics, workload regression detection, and grounded RAG/LLM explanations.
  • Implemented AST-based read-only SQL validation, pg_stat_statements workload ranking, plan baselines, and strict evidence and citation validation. Release evaluation achieved 12/12 rule-diagnosis, 12/12 no-answer behavior, and 9/9 Retrieval Hit@3, with 103 Python tests and 88.68% coverage.

Enterprise Data Software Engineering Intern

İSKUR Holding

Jun 2024 – Aug 2024

  • Optimized SQL-based enterprise data retrieval using SAP Open SQL joins, reducing processing time by 41%.
  • Developed backend validation and automation logic for contract, barcode, inventory, and operational-cost workflows, with transactional logging and structured audit trails.

Profile

About

I am a Software Engineer specializing in Python backend and AI systems. I build production-oriented APIs and retrieval-augmented applications, with hands-on experience in real-time inference, computer vision, async data workflows, and measurable AI services.
