Machine Learning Engineer at DPD Group

June 1, 2023 - October 25, 2025

Developed NLP-based voice AI chatbots and self-service assistants for parcel-delivery optimization (routing queries, anomaly alerts, voice command interface), cutting first-response times by ~30%. Designed streaming data ingestion (Kafka + Spark) from tens of millions of tracking events per day; built AI models for demand forecasting and anomaly detection, improving on-time delivery by ~12% and reducing failed first attempts by ~9%. Embedded agentic-AI workflows: LLМ-based agents autonomously trigger dispatch workflows, handing off to voice-chat interfaces, integrated with software teams, and reducing manual tasks.

Senior Machine Learning Engineer at Zalando SE

Led the creation of a personalized product-recommendation engine enhanced with GenAI-driven conversational features (chatbot module) and fine-tuned LLMs, increasing click-through. Architected a real-time inference micro-services stack (Kubernetes + Docker + AWS/GCP) reducing latency by ~35% while serving millions of daily events. Introduced Agentic-AI workflows: lightweight AI agents orchestrate multi-step tasks (user query → context lookup → recommendation → follow-up chat), reducing manual interventions by ~25%. Built MLOps infra including model versioning, monitoring & drift detection, and coached junior engineers across Europe on NLP, RAG pipelines and agent orchestration.

Machine Learning Engineer at Arçelik A.Ş.

December 1, 2019 - October 25, 2025

Created a computer-vision and NLP hybrid system for defect-detection paired with a human-feedback chatbot interface for manufacturing line workers, reducing inspection errors by ~30% and cost by ~20%. Deployed edge-device inference (<250 ms latency) and exposed REST APIs; integrated model outputs into operational dashboards used by senior stakeholders. Created dashboards for senior stakeholders to visualize model performance, error-rates and business-impact, enabling data-driven decision-making in manufacturing operations.

Data Scientist at Koç Digital

February 1, 2017 - October 25, 2025

Performed predictive analytics and statistical modeling on sales and inventory datasets, improving forecasting accuracy from ~70% to ~85%. Built executive-level dashboards (Tableau) and translated insights into actionable business strategies (dynamic pricing, supply-chain optimization). Partnered with business units to turn data into decisions— enabling improved responsive ness and resilience across commercial operations.
