Jagger Harness

Developer, Full-Stack (AI)

• Led backend and infrastructure development for enterprise Dialogflow CX chatbot platforms, building distributed TypeScript microservices on Cloud Run and Cloud Run functions with a React frontend.
• Upgraded 100+ microservices on Cloud Run functions to the latest Node.js runtime and later consolidated them into approximately eight to twelve Cloud Run services, reducing cold starts and operational overhead; met internal SLO targets during the transition through query optimization, targeted redesigns, and expanded caching.
• 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.
• Upgraded a legacy Salesforce Live Agent integration in the custom chatbot stack to a current, supported release with a full production cutover, keeping assistants available through the migration and rebuilding Looker Studio reporting one-to-one so analytics and leadership dashboards stayed equivalent.
• Reviewed code for a large contractor engineering team, keeping changes aligned with business requirements and internal engineering standards; worked with product owners and business analysts to add technical acceptance criteria, edge cases, and dependencies to Jira issues so delivery remained traceable to requirements.
• Partnered with geographically distributed engineers across multiple time zones on shared roadmaps, aligning delivery from planning through production releases.
• Architected systems to satisfy Cloud Architecture Review Board requirements and represented engineering in principal-level technical forums; presented regularly on architecture, tooling, and delivery to engineering and leadership audiences.
• Served as a Cursor Champion for AI-assisted development with shared documentation and practices; partnered with other teams to spot where agentic workflows could help, ran hands-on Cursor training, and coached safer agent-assisted coding.

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.
• Facilitated client meetings across discovery, delivery, and support, maintained trusted relationships with customer stakeholders, and partnered with client-side technical staff on shared initiatives from planning through release.
• 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.
• Assisted with quality assurance testing to validate that the completed work matched the acceptance criteria of Jira card.
