You will get a machine learning model and data pipeline in production
Rising Talent
Project details
I build machine learning that runs in your business, not a notebook you can't use. From your data, I train a custom model (prediction, classification, or scoring), wrap it in a clean data pipeline, validate it honestly, and can deploy it as an API your systems call. I'm a full-stack developer (9 years, 4 in AI) working in Python with pandas, scikit-learn and PyTorch, so I own both the modeling and the engineering to ship it. I care about the parts that make ML trustworthy: proper train/test splits (no leakage), the metric that actually matters for your case, feature engineering, and a clear accuracy report — no cherry-picked numbers. What you get: a validated model on your data (Starter); a data pipeline, feature engineering and an accuracy report (Standard); and deployment as an API, monitoring and a retraining plan (Advanced). Message me before ordering so I can confirm the goal, your data, and the right tier.

Job Success
Barcelona, Spain - 7:51 pm local time
I'm a full-stack developer with 8 years of experience, an AI developer for the last 5, focused on LLM systems for the past 3. With a degree in business and IT and a master's in AI, I move between the business side and the technical side without a translator: I can map your operation with you in plain language, then build and deploy the system end to end.
Recent systems, all in production and documented:
• A 24/7 AI teammate for a logistics company: answers operations questions, tracks containers with the carrier automatically, and delivers a daily 7 a.m. briefing (n8n, OpenAI, Supabase).
• A proposal engine for an events agency: reads each brief, finds and verifies suppliers, and contacts them automatically. A full brief takes 13-26 minutes instead of hours, with 0% classification errors.
• A marketing dashboard for a medical group: Meta and Google Ads synced daily, funnel per treatment line, investment vs. revenue. It also recovered ~107 ad conversions a tracking bug had been silently dropping.
I work in English and Spanish natively. My stack: Python, FastAPI, n8n, Make, OpenAI and Claude APIs, LangChain, WhatsApp Business API, Supabase, PostgreSQL, Docker. Self-hosted and production-grade, with documentation your team can actually use.
If you have a system in mind, tell me what's eating your team's time. I'll answer with a sketch of how I'd build it, and often with a small working prototype, because showing beats promising.
