I'll give you honest feedback on your project, identify challenges early, and architect scalable solutions. 🔵If you're looking for an AI developer with proven expertise and a track record of delivering real ROI, let's discuss your idea.

I've built AI systems that deflect 60% of support queries, search across 10,000+ documents in under 2 seconds, and save operations teams 20+ hours every week. The gap between those outcomes and a typical chatbot demo is architecture. Most teams reach out after a prototype has already failed in production, usually because of poor chunking logic, absent memory management, weak retrieval quality, or no fallback handling. I rebuild those systems correctly: clean ingestion pipelines, hybrid retrieval, structured agent memory, proper observability, and deployment that holds under real load. What I build: — RAG systems for internal documents, knowledge bases, and enterprise search — AI agents with tool use, memory, and multi-step reasoning (LangChain, LlamaIndex, LangGraph) — Automation workflows that replace manual operations (n8n + LLM + your existing APIs) — Production chatbots for web, WhatsApp, and Slack with escalation and analytics — Voice AI pipelines (STT + TTS) for customer-facing applications — Fine-tuned models for domain-specific classification and generation tasks Stack: Python · LangChain · LlamaIndex · LangGraph · OpenAI · Claude API · Pinecone · Weaviate · FastAPI · n8n · AWS · Docker If you're ready to move from prototype to production or want it built right from the start, I can map out your system architecture in a 20-minute scoping call. No prep needed on your end.

I am the Founder and AI Architect of an applied AI consultancy (Vantablan) where we design and deploy production grade machine learning systems that actually run in real environments. I personally lead the technical architecture and delivery, and we have over 4 years of hands on experience building computer vision and generative AI systems across sports analytics, healthcare, e commerce, and SaaS products. Our work is end to end. We take ownership from problem definition to deployment and long term stability. On the computer vision side, we build full pipelines around object detection, instance segmentation, pose estimation, and identity recognition. These systems run on live video streams and real world inputs, not research demos. I design the core model architecture and inference logic, while we optimize pipelines using PyTorch based models, YOLO style detectors, OpenCV, and modular deployment stacks focused on speed and reliability. In generative AI, we work on LLM fine tuning, controlled generation systems, and diffusion based pipelines used for automation, internal tooling, and content workflows. I stay closely involved in prompt design, evaluation logic, and model selection to ensure outputs are predictable and usable in production. We do not build demo chatbots. We build systems that plug directly into products. Beyond modeling, we own the AI infrastructure. I handle system design while we implement training pipelines, CI CD workflows, containerized deployments, and monitoring across AWS, GCP, and Azure so models ship cleanly and remain stable after launch. I also bring a strong research background with published work in deep learning and reinforcement learning, which informs our design decisions when rigor is required. Still, our priority is simple. Build systems that work, scale, and deliver measurable outcomes. Clients work with us when they need a team that can own the AI side of their product, make architectural calls, and deliver without hand holding.
