About
A systems-minded engineer focused on dependable delivery and operational clarity.
I design and deliver software systems that solve operational problems clearly and reliably. My work sits at the intersection of full-stack engineering, automation architecture, analytics tooling, and delivery leadership, with a consistent focus on turning business complexity into maintainable systems built with Node.js, React, SQL, and cloud infrastructure.
Working Style
My approach combines architecture thinking, hands-on delivery, and project ownership. I work comfortably across product and operational contexts, whether the challenge is integrating external APIs, designing reporting systems, or removing manual work through automation.
Currently focused on senior engineering, systems, and technical delivery roles where architecture clarity, execution speed, and business impact matter.
Current Direction
After a purposeful period of full-time field missionary work from September 2023 to January 2026, I am now re-engaging with software and systems development with strong engineering fundamentals, architecture experience, and an AI-assisted workflow that helps accelerate implementation and delivery.
Beyond Work
A small personal note
Outside of engineering, I'm a furparent, and my dogs have been beside me through long coding sessions since well before "vibe coding" became a buzzword.
Experience
Experience shaped by software delivery, systems design, and operational execution.
The emphasis throughout these roles is consistent: production systems, measurable efficiency gains, and ownership across architecture, implementation, and delivery.

Summary
Developed and published a Node.js module wrapper for Amazon Product Advertising API workflows, then supported real-world integrations for advertisers and developers building custom product tools, catalog workflows, and related automation.
Scope
This work combined developer tooling with practical production integration support, helping technical teams use Amazon product data more effectively inside internal tools and custom workflows.
Outcome
Improved developer usability for Amazon PA API integrations and enabled faster implementation across custom internal tools and advertiser workflows.

Summary
Designed and helped build an internal analytics platform that consolidated multi-source operational data into a single decision-support system for FBA inventory management and business insights.
Scope
Built as a scalable internal platform processing more than 1 million records. Before modern AI-assisted workflows became common, the system relied on programmatic rules, criteria-based automation, machine learning, analytics pipelines, and distributed micro-workers to execute background tasks reliably.
Outcome
Processed 1M+ records, improved business visibility across inventory and operational data, and reduced fragmented reporting and manual analysis.

Summary
Developed robotic process automation workflows using WinAutomation and custom multi-threaded worker logic to automate high-volume back-office tasks across multiple sales and order channels.
Scope
A key use case included automating repetitive order-entry workflows into supplier and B2B systems for dropshipping operations tied to Amazon order fulfillment. The system relied on structured workflow logic, automation rules, and concurrent workers rather than LLM-based automation.
Outcome
Automated tens of thousands of repetitive entries, improved speed and consistency across order operations, and reduced reliance on manual back-office processing.
