I am an AI Engineer with 4+ years of experience building and deploying production-ready AI systems across classical machine learning, deep learning, computer vision, NLP, and Generative AI. Unlike many AI developers who focus only on LLMs, I work across the entire AI stack. I believe the best solution isn't always a large language model or an expensive API. Many real-world problems are better solved using classical machine learning or deep learning, resulting in lower infrastructure costs, faster inference, reduced latency, and greater control over your solution. My goal is always to build the most effective system not the most expensive one. Some of the areas I regularly work in include: * Classical Machine Learning (XGBoost, LightGBM, CatBoost, Random Forests, SVMs, feature engineering, predictive modelling, forecasting, anomaly detection, recommendation systems) * Deep Learning (PyTorch, TensorFlow, CNNs, Transformers, Vision Transformers, knowledge distillation, model optimization) * Computer Vision (object detection, image classification, segmentation, OCR, document understanding, face recognition, multi-object tracking, embedding-based search) * NLP & LLMs (RAG, GraphRAG, agentic workflows, fine-tuning, embeddings, semantic search, document QA, information extraction) * Generative AI applications using OpenAI, Anthropic, Gemini, and open-source models * End-to-end AI pipelines from data collection and preprocessing to training, evaluation, deployment, and monitoring I also have extensive experience optimizing AI models for production through knowledge distillation, pruning, quantization, and efficient inference, making models smaller, faster, and more cost-effective for both cloud and edge deployments. On the engineering side, I work comfortably with Python, FastAPI, PostgreSQL, pgvector, asynchronous programming, Docker, GPU acceleration, and cloud deployments. I build complete AI products and APIs that are designed to scale not just research prototypes. Beyond implementation, I enjoy solving difficult research and engineering problems. Whether it's designing a predictive model, improving model accuracy, reducing inference costs, building an intelligent document processing pipeline, or deploying an LLM application, I focus on solutions that are reliable, maintainable, and practical for production. I also lead a team of AI engineers, giving me experience not only in technical execution but also in planning, code quality, mentoring, and delivering projects on time. If you're looking for someone who can understand the problem first, choose the right AI approach, and build a production-ready solution that balances performance, cost, and scalability, I'd be happy to help.

I donโ€™t just write code; I design intelligent systems that bridge the gap between complex manual workflows and autonomous AI solutions. As a Computer Engineering student at Ankara University (English-medium), I focus on architecting, breaking, and refining high-stakes AI projects. Whether you need a 12-platform content distribution engine or a custom autonomous agent, I focus on building scalable, error-resistant architectures that save time and reduce costs. Core Expertise: Advanced Automation (n8n): Expert in designing complex, multi-node workflows and API orchestrations. I specialize in connecting disparate platforms (Social Media, CMS, Databases) into a single, cohesive engine with robust error handling. AI & LLM Integration: From building a Mini-GPT from scratch to developing Ghost Operator (Nexus)โ€”an autonomous PC assistant with vision and voiceโ€”I have a deep understanding of how to leverage LLMs (OpenAI, Claude, Llama) for real-world tasks. Data-Driven Logic: Creator of FinSight AI, a stock analysis tool for Borsa Istanbul (BIST), utilizing technical indicators (RSI, MACD, Bollinger Bands) to provide AI-driven market insights. Technical Toolkit: Automation: n8n, Web Automation, System Integration (APIs). Languages & Frameworks: Python, PyTorch, FastAPI, Streamlit. Core Strengths: Prompt Engineering, Software Architecture, Algorithmic Trading logic. I believe in high-quality, manual coding to ensure system stability. My philosophy is simple: Automate the repetitive, architect the future. You can review my technical depth and project source codes on my GitHub. Letโ€™s turn your manual workflows into a high-performance AI powerhouse. Message me to discuss your projectโ€™s architecture.

I build production AI agents, RAG systems, and workflow automation on the Claude, OpenAI, Gemini, Grok APIs. Not demos that die after the pitch meeting: systems with guardrails, human review steps, and escalation logic that run every day without babysitting. Over the past few years I've shipped autonomous agents, RAG pipelines, and conversational AI running live on WhatsApp, Instagram, and Line, plus full AI-native products: web apps, custom CRMs, and analytics dashboards designed around LLMs from day one instead of having AI bolted on later. Everything in TypeScript/Node.js or Python, deployed on GCP and AWS. One recent build: a contract analysis pipeline for the music industry. Specialized agents for Producer, Mixer, Featured Artist, and Publishing deals run under a LangGraph supervisor on Cloud Run. Document review that took hours per deal now takes minutes. Problems clients bring me: - Business process automation: lead capture and qualification, CRM updates, email and document processing, wired together with n8n, custom code, and LLM APIs. Anything that writes to your real data goes through an approval step first. - Customer-facing chatbots and support agents on WhatsApp, Instagram, Line, and web, with real memory, answers grounded in your own knowledge base so they don't invent things, and clean handoff to a human when confidence drops. - AI agents and multi-agent systems for workflows too complex for a single prompt, built on LangGraph and the Claude Agent SDK. - RAG pipelines and semantic search at production scale with Pinecone, PGVector, and ChromaDB. - CRM and ERP integrations: GoHighLevel, Follow Up Boss, Gmail and Google Workspace, third-party APIs. - AI-native SaaS end to end. I built and shipped ReserveNova, an AI booking platform for hospitality. - Document intelligence: contract analysis, invoice and data extraction, real-time LLM-powered dashboards. How I work is simple. I scope the architecture before writing a line of code, get you a working prototype within 48 to 72 hours so you can validate direction early, then build toward production with proper error handling, evaluation, logging, and observability. Everything runs in your accounts, documented well enough that your team can maintain it without me. You own it all at handoff. My background runs deeper than the LLM wave: years of hands-on NLP work with transformers and spaCy before agents became the trend. That's why my pipelines handle messy real-world language instead of breaking on it. Stack: TypeScript/Node.js, Python, React/Next.js, Claude API, OpenAI API, LangGraph, LangChain, LlamaIndex, CrewAI, MCP, Pinecone, PGVector, ChromaDB, n8n, GCP Cloud Run, AWS Lambda, Docker. I keep my project load small so each build gets real attention. If you're building an AI product from scratch, adding agents or RAG to an existing app, or drowning in a document-heavy workflow, send an invite and tell me what you're trying to build. I'll tell you honestly whether it's a fit.
