Back to original languageAbout Martin
I help startups and SMEs stop wasting time on repetitive tasks and disorganized data.
My dual expertise in data and development allows me to cover the entire pipeline: from clean data collection to the dashboard your team uses daily, with automations that run themselves in between.
🎯 3 areas of expertise I truly master
→ No-code / Low-code Automation
n8n, Make, Zapier workflows. Connect your CRM, marketing tools, database, and AI APIs into a system that runs 24/7 without intervention.
→ Pragmatic Data Engineering
Cleaning and structuring databases (CSV, Excel, SQL, APIs). ETL, deduplication, reproducible Python pipelines. Prepare your data for analysis, reporting, or AI.
→ Websites Connected to Your Business
React + Node / Python FastAPI. Showcase websites, real-time data dashboards, interfaces to leverage your AI models, API integration.
🚀 Concrete Examples
— Lead-to-CRM Pipeline: Daily cleaning of 50k multi-source leads → HubSpot. Savings: ~15h/week for the sales team.
— Real-time Dashboard: Aggregation of 3 tools (Stripe, Notion, GA4) → React + FastAPI. Key management KPIs calculated live.
— Client Onboarding Automation: n8n workflow that orchestrates email, Notion, Slack, and Stripe invoicing upon signature.
