Automation Systems Engineer | Make, n8n & Custom Integrations

Businesses rarely have a software problem. They have a systems problem. Teams lose hours every week moving data between disconnected applications, manually processing documents, following up with customers, and maintaining workflows that should already run on their own. I design and build production-ready automation systems that eliminate manual work, connect business-critical applications, and keep operations running reliably at scale. My work goes beyond building workflows. I engineer systems that businesses depend on every day. That includes automation architecture, API integrations, AI-assisted document processing, internal platforms, and custom software that extends automation where no-code tools reach their limits. I use AI where it creates measurable business value. If a simpler solution is more reliable, easier to maintain, or more cost-effective, that's the approach I'll recommend. ## What I Build ✓ Business process automation for operations, finance, sales, and customer success ✓ End-to-end workflow automation with Make and n8n ✓ API integrations between SaaS platforms, CRMs, databases, and internal systems ✓ AI-assisted document processing, classification, extraction, and routing ✓ Internal tools and full-stack applications that support business operations ✓ Automation monitoring, logging, retries, alerts, and failure recovery ✓ Production systems designed for long-term reliability and maintainability ## Selected Projects 1, Enterprise Accounts Receivable Automation Designed and built a multi-tenant accounts receivable platform that automates invoice reminders across multiple business locations. The system integrates ServiceTitan with Constant Contact, manages staged payment reminders, handles platform limitations, prevents duplicate sends, and automatically cleans up temporary contacts to stay within platform limits. The solution runs as a modular webhook-driven architecture with logging, retries, and operational safeguards built in. 2, Content Operations Platform Built a fully automated content pipeline that transforms news, research, and competitor content into branded posts ready for publication across LinkedIn, X, Webflow, and Google Docs. The system includes content sourcing, rewriting, quality scoring, brand enforcement, media generation, publishing, monitoring, and centralized configuration without requiring daily manual involvement. 3, Document Intelligence Pipeline Engineered a multi-stage document processing system capable of handling scanned documents, PDFs, reports, and structured files. The pipeline automatically selects the most appropriate extraction strategy based on document complexity, validates extraction quality, escalates when confidence is low, and produces structured, searchable knowledge with complete source traceability. 4, Custom Automation Systems Designed automation platforms that combine APIs, business logic, databases, and AI services to replace repetitive operational work with reliable production systems. Every solution is built with modular architecture, documentation, monitoring, and maintainability as first-class requirements. ## Technologies 1, Automation n8n, Make, Zapier 2, Development Python, Node.js, React, Next.js 3, Infrastructure AWS, GCP, REST APIs, PostgreSQL, Docker, Cloud Deployment ## How I Work Every project starts with understanding how the business operates before discussing tools. I start by identifying where time is being lost, where manual work creates bottlenecks, and where automation will deliver the highest return. From there, I design a solution that fits the business instead of forcing the business to adapt to the technology. Production systems need more than working workflows. They need thoughtful architecture, error handling, logging, monitoring, documentation, and room to evolve as the business grows. That's the standard I build to. Whether the solution is built entirely in Make or n8n, requires custom backend services, or combines both, my objective is always the same: deliver automation that is dependable, maintainable, and continues creating value long after deployment. If you're looking for an engineer who can understand your business, design the right solution, and build systems your team can rely on, I'd be glad to discuss your project.
