I build backend automation systems that connect APIs, process data, and deliver results — without the manual work. My focus is on three areas: API & Webhook Integration: Connecting third-party services (payment APIs, CRMs, marketing platforms) and building event-driven workflows that respond automatically to real-time data. AI-Powered Tools: Building chatbots, automation pipelines, and data extraction systems using OpenAI and Claude APIs — from simple integrations to multi-step agentic workflows. Data Pipelines & Automation: ETL systems, web scrapers, and scheduled data collection tools that deliver clean, structured output to Google Sheets, databases, or any destination you need. My last client said I delivered a dataset that "would have taken most far longer" — completed in under 24 hours. If you need something built fast and built right, send me a message.
