I focus on clean architecture, fast communication, and production-ready delivery. If you need a senior developer for a complex product build or a critical feature sprint, send me the brief and I'll outline the fastest path to ship it.

Most AI/ML projects fail after the demo. The model works. The notebook looks great. But in production? Slow responses. Hallucinations. Poor forecasts. Scaling issues. No monitoring. No real ROI. That’s where I come in. I design and deploy production ready AI systems not experiments. From LLM applications and AI agents to forecasting engines and spatial intelligence platforms, I build systems that are stable, scalable, and built for real business workflows. 🔹 What I Build • Custom LLM apps (GPT, Claude, Llama) • Retrieval-Augmented Generation (RAG) with vector databases • AI agents & workflow automation • Private knowledge assistants over company data • Time-series forecasting & anomaly detection systems • Trading & financial signal models • GeoAI / spatial ML pipelines (predictive mapping, mineral targeting) • ML APIs & decision-support dashboards 🔹 End-to-End Execution Data pipelines → Feature engineering → Modeling → Evaluation → Deployment → Monitoring No fragile prototypes. No black-box confusion. Just structured, measurable AI systems. I combine deep ML expertise (PyTorch, TensorFlow, Transformers) with backend engineering (FastAPI, SQL, cloud deployment) so your solution performs under real-world load. If you’re facing: • Unreliable LLM outputs • AI hallucination issues • Forecasting models that lack accuracy • Poorly structured data pipelines • AI tools that don’t integrate into workflows Let’s fix it properly. I focus on clarity, performance, and long-term scalability so your AI becomes an asset, not a liability. Let's get connected and talk about the problem you are facing to make it production ready and scalable.
