Jagger Harness

Developer, Full-Stack (AI)

• Lead backend and infrastructure development for enterprise Dialogflow CX chatbot platforms, building distributed TypeScript microservices on Google Cloud Run and Cloud Run functions with a React frontend.
• Led modernization from Dialogflow ES to Dialogflow CX, delivering the majority of backend services and Terraform-provisioned infrastructure for the production architecture.
• Upgraded 160+ Google Cloud Run function microservices to the latest Node.js runtime and later consolidated them into approximately eight to ten Google Cloud Run services, reducing cold starts and operational overhead; met internal SLO targets during the transition through query optimization, targeted redesigns, and expanded caching.
• Designed and implemented a universal client and proxy layer so internal teams integrate Dialogflow CX agents or live-agent providers through a single shared interface.
• Provisioned and operated Google Cloud Platform (GCP) infrastructure with Terraform for containerized workloads, including IAM and workload identity federation; raised automated test coverage above 90% on priority services; improved GitLab CI/CD pipelines for testing, deployments, accessibility validation, and Node.js runtime upgrades.
• Architected systems to satisfy Cloud Architecture Review Board requirements and represented engineering in principal-level technical forums; partnered with business stakeholders from planning through launch; served as a Cursor Champion for AI-assisted development with shared documentation and practices; presented regularly on architecture, tooling, and delivery to engineering and leadership audiences.

Full Stack Software Developer

• Owned full-stack delivery for multiple client engagements from discovery through production, coordinating 5-6 onsite and 10-12 offshore developers, unblocking work, promoting stronger implementation and testing practices, and keeping releases on schedule.
• Improved a legacy API by 50-70% average response time through tooling upgrades, query optimization, and database-focused refactors.
• Led a multi-month migration of a 10+ year PHP monolith to Laravel, preserving core business logic while restructuring around Laravel conventions, improving maintainability, security, and performance.
• Built a city-scale traffic-camera analytics web application (four cities, scheduled email ingestion every twelve hours, 1M+ database records), owning architecture and implementation end-to-end with selective delegation.
• Shipped a Flutter fuel-delivery app to both major app stores with Stripe billing and a Laravel admin interface for operations; implemented subscription sync and feature gating so entitlements stayed consistent with Stripe state.
• Delivered a conveyor and IoT operator app integrating with hardware; implemented Bluetooth Low Energy in C/C++ on the device module alongside an electrical engineer, reducing reliance on traditional PLC programming for standard workflows.

Junior Software Development Intern

• Investigated and resolved client-reported defects across multiple websites and applications while performing routine maintenance on varied technology stacks.
• Collaborated with project management and engineering to estimate work and ship features according to specifications.
