Work history

• Architected and productionized a Flow-Based Programming data graph streaming platform, replacing a multi-week manually coordinated release process with on-demand delivery; currently handles ~2.5M events/day across two tenants in active onboarding.
• Backing datasets cover ~355M people, ~436M phones, ~483M emails, and ~234M addresses; the platform also powers a real-time pipeline streaming scraped public-records data to subscriber webhooks.
• Own architecture decisions, the function server, the pipeline compiler (built on a CUE-based DSL), metrics and logging, and bulk ingestion/export operations.
• Built avmbench, a Property and People data delivery platform that unlocked a $1M net new revenue source — covering ~125M properties across all 50 states with a 17.1% national median error rate on valuation estimates, built on a custom geographic aggregation DSL and Census TIGER pipelines.
• Designed and shipped P95-latency-based load shedding for the search layer in Scala — ring-buffer windowed computation, OPEN/TRIPPED state machine with hysteresis, 429-with-Retry-After rejection — wrapping all 18 route handlers.
• Led migration of 2.5M events/day from Amplitude to Databricks Delta tables, eliminating several thousand dollars per month in overage fees while preserving the Salesforce/Kinesis ingest path.
• Drove monorepo migration with shared tooling, standardized linting, and Nix-based developer environments — supporting ~100 service releases per week and shifting CVE scanning from infrequent reactive scans to proactive CI gates.
• Built pagecraft, an internal developer-productivity CLI adopted across the team — PR review workflow with parallelized GitHub fetches and Nix/darwin tooling.
• Built MCP integration and AI inference harness on the engineering platform; authored "Jon's Workflow with AI," adopted org-wide as the reference for AI-assisted engineering practice.
• Combined hands-on mentorship and operationalized agentic AI with a robust spec process to lift delivered work 2.5-4x year-over-year, leaving the team running ahead of business demand with real operational headroom despite shrinking headcount.
• Sustained high-volume, substantive peer code review across the platform org — 261 reviews in the first 15 weeks of 2026 alone (~75/month, mean 6 / median 4 comments per PR, ~1,000-line PR average) — reinforcing engineering standards and a small-PR discipline.
• Authored org-wide strategy documents (Whitepages as a Platform, Single Source of Data Definitions, Data Release Tenets) shaping platform architecture and release governance.

Technology: Python, Rust, Scala, CUE, Nix, Kubernetes, Helm, Databricks, Delta Lake, MCP

• Managed and mentored a team of 6 engineers on the consumer web platform (SEO, Core Web Vitals, conversion optimization, GDPR compliance).
• Led delivery on LCP regression fixes for high-traffic page types, INP tracking ahead of Google's CWV INP rollout, and an org-wide OneTrust GDPR cookie consent rollout.
• Returned to the IC track in Jun 2023 to focus on data platform architecture.

• Reversed a multi-quarter decline in Google indexation, increasing indexed pages 30%.
• Drove dozens of millions of SERP-indexed URLs from red LCP (Core Web Vitals failure) to zero, with monitoring automation to keep them green.
• Increased mobile revenue by 20% YoY by focusing on stability and adding new features.
• Made tooling and documentation improvements to reduce friction and speed up delivery for the whitepages.com and mobile app teams.

• Built a new React Native application to replace separate native iOS and Android applications.
• Added new features to iOS and Android native applications to support a new LIFX power switch product.
• Worked with a team of three for four months to replace a fragile monolithic platform with a new microservice-based platform, saving $120k a year while improving availability and maintainability.
• Built a React Native application for Airstream's Smart platform; led mobile development and authored custom native plugins for unique connectivity scenarios.
• Built tooling and test frameworks for code quality (type-checking, linting, unit testing) and regression/UX testing (Storybook, screenshot diffing, Detox E2E).
• Architected an end-to-end "checklist service" as a fully tested Micronaut microservice with CRUD support and a performance-optimized client API.

Technology: React Native, TypeScript, Java, Swift, Kotlin, Micronaut, PostgreSQL, Azure, MQTT, HomeKit

• Extended a Cordova mobile application, built React Native and Flutter proof-of-concept apps, and created a test automation framework.

• Delivered a React Native application for TERRA Staffing and an Alexa skill for TD Bank.

• Added value as an individual contributor (averaging 120% billable utilization) while supporting business goals to build a full-stack development team which grew as large as 12 developers.
• Successfully delivered 13 web and hybrid mobile application projects for clients including Microsoft, Premera, Capital One, Belkin, and Entertainment Partners.
• Led architecture shift from server-rendered ASP.NET MVC to Web API + Angular on Microsoft's Cloud Launchpad portal, decoupling frontend and backend concerns.
• Served as lead mobile developer on the Belkin Linksys consumer app, with the team delivering on schedule for the CES launch window.

Technology: ASP.NET Core, C#, Node, MS SQL, Azure, AWS, React, Angular 2+, PHP, WordPress, Elasticsearch

• Finished three client projects (each estimated between 4 and 6 months) early and under budget.
