I build, fix, and maintain production automation systems — primarily in n8n. My work sits at the intersection of workflow orchestration, API integration, and operational reliability. If your business runs on automated pipelines that need to work every single time, that's where I operate. ▸ 𝗖𝗼𝗿𝗲 𝗘𝘅𝗽𝗲𝗿𝘁𝗶𝘀𝗲 My typical engagement involves multi-step pipelines with structured data flow, state management, error handling, and integrations spanning 5–15 services. I am not a script writer — I think in systems. n8n is my primary platform. I work daily with self-hosted instances, understand credential management deeply, and am fluent in building code nodes (JavaScript), webhook triggers, sub-workflows, retry logic, and execution monitoring. I've debugged everything from silent OAuth token expiration to race conditions in polling-based sync workflows. ▸ 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝗶𝗲𝘀 𝗜'𝘃𝗲 𝗪𝗼𝗿𝗸𝗲𝗱 𝗪𝗶𝘁𝗵 𝘈𝘶𝘵𝘰𝘮𝘢𝘵𝘪𝘰𝘯: n8n, Zapier, Make · 𝘓𝘢𝘯𝘨𝘶𝘢𝘨𝘦𝘴: Python, JavaScript, C#, PHP, Rust, C, Java, SQL, HTML/CSS, Bash, Nushell, Pinescript, Google Apps Script · 𝘍𝘳𝘢𝘮𝘦𝘸𝘰𝘳𝘬𝘴: Django, FastAPI, Node, ASP.NET, React, Svelte/Kit, Astro · 𝘋𝘢𝘵𝘢𝘣𝘢𝘴𝘦𝘴 & 𝘖𝘙𝘔𝘴: PostgreSQL, SQLite, Azure SQL, Firebase, Drizzle, Prisma, SQLAlchemy, GraphQL · 𝘊𝘭𝘰𝘶𝘥 & 𝘏𝘰𝘴𝘵𝘪𝘯𝘨: AWS, Google Cloud Functions, Azure Container Apps, Azure DevOps, Railway, Hetzner, Scaleway, Vercel, Netlify, Heroku · 𝘋𝘦𝘷𝘖𝘱𝘴: Git, GitHub Actions · 𝘉𝘶𝘴𝘪𝘯𝘦𝘴𝘴 𝘛𝘰𝘰𝘭𝘴 & 𝘊𝘙𝘔: Salesforce, Microsoft Dynamics, SharePoint, Retool, Google Sheets, Google Contacts, Gmail API, Zoom · 𝘌-𝘤𝘰𝘮𝘮𝘦𝘳𝘤𝘦 & 𝘞𝘦𝘣: Shopify, Stripe, WordPress, Wix, Webflow · 𝘈𝘐: Claude, OpenAI · 𝘚𝘤𝘳𝘢𝘱𝘪𝘯𝘨 & 𝘛𝘦𝘴𝘵𝘪𝘯𝘨: Playwright, Selenium · 𝘈𝘶𝘵𝘩 & 𝘔𝘰𝘯𝘪𝘵𝘰𝘳𝘪𝘯𝘨: Auth0, OpenObserve · 𝘖𝘚: NixOS, Pop!

Systems should fail visibly, never silently. I build quality filters before record creation to prevent ghost records, implement rate limit compliance, and ensure every execution is traceable from trigger to completion. 𝘚𝘵𝘳𝘶𝘤𝘵𝘶𝘳𝘦𝘥 𝘋𝘢𝘵𝘢 𝘍𝘭𝘰𝘸 — I design sanitization layers (name normalization, date formatting, phone cleanup, case number parsing) as reusable functions applied consistently across workflows. Data quality is enforced at the boundary, before it propagates downstream to documents, calendar events, or external APIs. 𝘋𝘰𝘤𝘶𝘮𝘦𝘯𝘵𝘢𝘵𝘪𝘰𝘯 — Every deliverable comes with written technical documentation: what was built, what it connects to, how it handles failure, and how to extend it. I write docs so that another developer — or you — can maintain the system without me. 𝘔𝘢𝘪𝘯𝘵𝘢𝘪𝘯𝘢𝘣𝘭𝘦 𝘏𝘢𝘯𝘥𝘰𝘧𝘧 — I build clean setups that clients can manage after delivery. Configuration lives in sheets or Airtable tables, not hardcoded in workflow nodes. When I leave, the system keeps running. ▸ 𝗧𝘆𝗽𝗶𝗰𝗮𝗹 𝗣𝗿𝗼𝗷𝗲𝗰𝘁𝘀 → Multi-step intake automation: form submission → AI data extraction → database record creation → folder provisioning → notification alerts → Email automation pipelines: Google Sheets trigger → AI-generated personalized emails → Gmail send → status tracking → follow-up sequences → CRM-to-outreach systems: lead status webhooks → PDF offer generation → timed email sequences → bidirectional status sync → Social media posting: sitemap parsing → content scheduling → multi-platform publishing (Facebook, X, Threads) → Freelancer/candidate screening: data extraction → AI evaluation pipeline → ranking → follow-up question generation → OAuth integration setup: developer console registration → scope mapping → credential vault storage → tested n8n connections → Personal productivity systems: email/calendar/task capture → smart digest generation → Slack/SMS notifications ▸ 𝗛𝗼𝘄 𝗜 𝗪𝗼𝗿𝗸 Same-day response on urgent issues. Plain language, direct communication. I scope before I quote and provide hourly breakdowns on request. I'm comfortable with milestone-based fixed pricing, hourly arrangements, or monthly retainers for ongoing maintenance. For retainer engagements, I proactively monitor execution logs, catch failures before they're reported, and deliver monthly status reports covering what was fixed, what was monitored, and what needs attention. Available 15–30 hours/week. Flexible on timezone overlap.
