# Mehmet Demirci

> AI Solutions Engineer in Turkey, UAE & remotely available worldwide. Seven years building AI systems that run in production: LLM agents, retrieval pipelines, and computer vision on real hardware under real load.

I've spent most of my career on the part that comes after the model works. The async services, the retries, the evaluation harness, the deployment. A model that's right once is a demo. Keeping it right on the thousandth request is the actual job, and it's usually where the time goes.

Right now I work mostly on LLM agents: multi-step tool use, retrieval over knowledge graphs, and a lot of unglamorous plumbing to make non-deterministic systems reliable enough to sit inside a business process. Before that I did computer vision on edge hardware for road and rail safety, where a wrong answer at 60 frames per second isn't an abstract cost.

The problems I enjoy tend to have the same shape. Model accuracy is fine; the hard constraint is somewhere else. Latency budgets, inputs nobody cleaned, or the distance between a benchmark score and how the thing behaves on an ordinary Tuesday.

## Projects

- [Document Intelligence Suite](https://mdemirci.dev/projects/document-intelligence-suite/): Three parsers reading invoices, emails and timesheets past 90% field accuracy, including the ones that arrive as photos of paper. (2026 · In production)
- [Sales Comment Moderation](https://mdemirci.dev/projects/comment-moderation-llm/): A locally trained LLM that moderates comments on sales listings in-house, so customer text never leaves the building to get a label. (2026 · In production)
- [Sales Lead Proposal System](https://mdemirci.dev/projects/sales-lead-proposal-system/): A lead qualification and proposal engine that predicts purchase intent with semantic similarity rating, instead of asking an LLM to score leads directly. (2025 · In production)
- [Enterprise Knowledge Graph](https://mdemirci.dev/projects/enterprise-knowledge-graph/): Agentic pipelines that turn scattered public data on European enterprises into a graph you can query. (2024 · In production)
- [Real-time TTS for cluster-meet](https://mdemirci.dev/projects/realtime-tts-cluster-meet/): R&D on a text-to-speech stack fast enough to speak inside a live meeting, where latency is the whole product. (2026 · R&D)
- [Noise Suppression for cluster-meet](https://mdemirci.dev/projects/noise-suppression-cluster-meet/): R&D on removing background noise from live meeting audio without eating the speech underneath it. (2026 · R&D)
- [Tunnel & Highway Incident Detection](https://mdemirci.dev/projects/tunnel-incident-detection/): Real-time vision for road incidents across Turkish highways and tunnels, running on roadside hardware because a datacenter round-trip was too slow. (2021 · Deployed)
- [Rail Crossing Incident Detection](https://mdemirci.dev/projects/rail-crossing-detection/): Object detection at Serbian level crossings, flagging hazards in the danger zone while there's still time to act on them. (2021 · Deployed)
- [3D Port Container Scanner](https://mdemirci.dev/projects/port-container-scanner/): ML over 3D scans of shipping containers at an Istanbul port, raising throughput while cutting misreads. (2021 · Deployed)
- [Variable Message Sign Systems](https://mdemirci.dev/projects/variable-message-signs/): Roadside signage for traffic guidance, designed, built and deployed across several Turkish cities. The failure mode is a sign nobody can read. (2020 · Deployed)
