You will get an automation that follows up every lead so none goes cold (n8n/Make)
Rising Talent
Project details
Most leads go cold because the reply comes hours late. I build an automation that reacts the second a lead comes in: it captures them, replies instantly, logs them in your CRM, and follows up on a schedule until they answer — so your team only talks to people who are actually ready. I'm a full-stack developer (9 years, 4 in AI). I connect the tools you already use (forms, WhatsApp, email, your CRM) into one reliable flow with clean error handling and alerts, not a fragile Zap that breaks silently. You get instant capture from your source, an auto-reply in seconds plus a smart follow-up sequence, leads logged and tagged in HubSpot / GoHighLevel / Airtable / Sheets, routing to the right person with reminders, and a dashboard so you see speed-to-lead and conversion at a glance. Message me before ordering to confirm your stack and the right tier.

Job Success
Barcelona, Spain - 10:50 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.
