Professional Summary

Senior AI engineer with 6+ years shipping production-grade LLM, generative-AI and computer-vision systems. I design scalable AI/ML platforms — multi-agent LLM systems, RAG and retrieval/ranking pipelines, LLM evaluation, and hybrid setups that pair generative models with deterministic processing. Proven, measurable impact: ~75% faster training, +15pp IoU over commercial baselines, and pipelines serving 300K+ samples (up to 1M points). Strong hands-on background in PyTorch, distributed training, inference optimization, MLOps and cloud, with end-to-end delivery alongside domain experts and stakeholders.

3D Generative AI · LLM Systems · MLOps · Production deployment.
  • Designed and productionized large-scale 3D generative AI (Diffusion, Rectified Flow, GANs, VAEs) on 300K–350K+ samples (up to 1M vertices) — modular framework, unit-tested, Dockerized, K8s-ready.
  • Cut training time ~75% (12 → 3 days) with DeepSpeed ZeRO, bf16 mixed precision, FlashAttention and LoRA/PEFT across cost-efficient multi-cloud GPUs.
  • Built LLM evaluation pipelines (LangChain + LLM APIs) and exposed geometry-processing libraries as MCP tools for LLM-driven, tool-augmented workflows.
  • Ran human-in-the-loop feedback with domain experts via a custom A/B + rating annotation tool; collected preference data, retrained models, and tracked win-rate to catch quality regressions.
  • Improved 3D segmentation mean IoU ~15pp (≈80% → ≈95%), surpassing commercial baselines for manufacturing-grade applications.
  • Built scalable async FastAPI inference (multi-user, monitored, Locust-load-tested) and large-scale 3D data pipelines with multi-GPU CI/CD (MLflow, W&B).
Tools: PyTorch, Diffusion/Rectified Flow, DeepSpeed, LangChain, MCP, FastAPI, Docker, K8s, GCP, MLflow, W&B

2022 – 2024 · Türkiye / Global
Multimodal AI · NLP/LLM · Computer Vision · Search & Retrieval.
  • Core contributor in a 500+ engineer global R&D initiative, building multimodal AI systems and PoCs across NLP, vision and time-series, moving research into production.
  • Designed LLM-driven retrieval & ranking (RAG) combining layout detection (YOLO), semantic embeddings, dense retrieval, NER and FAISS vector search for automated resume-job matching.
  • Built a global-scale sign-language production system (transformer LLMs, Text→Sign, Sign→Pose) with aligned text/3D-pose pipelines on Huawei Cloud.
  • Developed LLM augmentation via function-calling APIs for synthetic training data and structured outputs; optimized transformer/vision models for Ascend hardware (MindSpore).
  • Benchmarked time-series forecasting (FEDformer, Autoformer, Informer) on multi-source telecom data; built energy-consumption forecasting PoCs (LSTM, Transformer, XGBoost).
