I build and maintain n8n, Make, and Python automation systems, lead enrichment, cold outreach, web scraping, and AI-agent workflows for agencies and founders. 5 of my 6 completed Upwork contracts turned into repeat or extended work. Since 2024 I've worked with agencies and founders as an ongoing execution partner, not a one-off contractor. Five of my six completed Upwork contracts turned into repeat work or extended engagements, because once a system is in production, my job isn't done. I'm the person who notices when an API changes shape, when a scraper's data quietly degrades, or when a workflow needs to scale from 50 leads a week to 500. WHAT LONG-TERM COLLABORATION WITH ME LOOKS LIKE: I own the outcome, not just the ticket. If a client's biggest bottleneck is "our lead enrichment breaks every time HubSpot changes a field," I don't just patch it. I redesign it so it stops happening. I build for maintainability from day one. Error handling, Slack/email alerting on failures, and clear documentation your team can actually read. Systems I hand off get touched by other people, and I ensure they run smoothly without turning into support headaches months down the line. I'm available for the critical maintenance work. Monitoring, small adjustments as your business changes, and migrating off tools that get too expensive (such as migrating off Zenrows to slash scraping costs). Long-term clients don't need a hero; they need someone dependable. RECENT LONG-TERM WORK: Built and have maintained an outreach automation system for an agency client since February 2026 (ongoing). AI automation specialist engagement, in progress since December 2025. Built a role-detection system that scans hundreds of company websites daily for open positions and syncs results automatically to a client's tracking sheet, running unattended since mid-2025. WhatsApp + Google Sheets + AI communication pipeline for a client, later extended into a month of post-launch support at the client's request. WHAT I BUILD: Social & Messaging Automation: Meta API, WhatsApp Cloud API, and Instagram automations for DM sequences, customer support routing, lead capture, and engagement tracking. Multi-Platform Content Distribution: Social automation using Zernio API and platform APIs across Instagram, Pinterest, Twitter/X, and Reddit to automate publishing, curation, and social listening. Cold Outreach & Lead Generation: Cold email pipelines powered by Instantly API, integrated with CRM syncs, automated warmups, and verified lead enrichment. Website Automation, SEO & CMS: Automated SEO monitoring, programmatic content publishing, dynamic indexing pipelines, and headless CMS automations across Ghost, WordPress, and custom static sites. Data & Scraping Pipelines: Production-grade scrapers (Python, Scrapy, Crawlee, Playwright) with proxy rotation, rate-limit handling, and structured output to Postgres, Sheets, or your CRM. n8n & Make Workflow Automation: Multi-step workflows connecting CRMs, comms tools, databases, and third-party APIs with failure alerting built in, not bolted on. AI-Enriched Pipelines: LLM integration (OpenAI, Gemini, Anthropic) inside production workflows for lead enrichment, classification, document parsing, and RAG pipelines. I optimize prompt structure and model selection to keep token costs sane at scale. API Integrations & Custom Backends: FastAPI services, OAuth2, webhooks, and REST APIs connected across Stripe, HubSpot, GoHighLevel, Airtable, Notion, Slack, Google Workspace, and 50+ other platforms. Deployment & Reliability: Self-hosted n8n on VPS, GitHub Actions scheduling, Cloud Run / Railway deployment. Every system ships with monitoring and complete documentation. STACK: Orchestration: n8n (Cloud/Self-Hosted), Make, Zapier Social, Comms & Outreach APIs: Meta Graph API, WhatsApp Cloud API, Instagram Automation, Instantly API, Zernio API (Instagram, Pinterest, Twitter/X, Reddit) Web & Content Systems: Ghost, WordPress, Programmatic SEO tools, Search Console / Indexing APIs Languages: Python, Node.js, JavaScript AI: OpenAI, Gemini, Anthropic, RAG vector pipelines Data: PostgreSQL, Airtable, Google Sheets Scraping: Scrapy, Playwright, Crawlee, Selenium Backend: FastAPI, REST APIs, Webhooks, OAuth2 Deployment: VPS, Google Cloud Run, Railway, GitHub Actions, Vercel If you're looking for someone to build a workflow once and vanish, I'm probably not the best fit. If you want someone who treats your automation stack like their own infrastructure, send me your biggest manual bottleneck and I'll tell you exactly how I'd automate it and keep it alive.
