About

Professional summary

I am a full-stack engineer and technical leader with 12 years of experience building and shipping web platforms, with a focus on AI products over the past two years.

I work across frontend, backend, and platform engineering using JavaScript, TypeScript, React, Vue, Angular, Node.js, Python, Java, C#, and .NET. I enjoy owning problems end to end, from API contracts and system architecture to polished user interfaces and documentation.

I am the founder of DataToRAG, an MCP gateway that gives AI agents authenticated access to Google Workspace and Atlassian products. I built its OAuth workflows, tool registry, streaming integrations, metering, billing, analytics, and production test infrastructure.

At Nativo, I have led platform engineering teams, managed hiring and planning processes, and delivered major platform features. I also led the company’s first AI-driven creative-generation product from an internal hackathon through production.

My experience includes building design systems, component libraries, developer tooling, data-security services, and self-service products. I value clear technical direction, strong team communication, practical documentation, and delivering reliable products that solve real customer problems.

Experience

Career history

Founder and Engineer DataToRAG, Inc.

I built and operate an MCP gateway connecting AI agents to Gmail, Calendar, Drive, Docs, Sheets, Slides, Contacts, Tasks, Jira, and Confluence. The platform provides about 100 tools through a single authenticated endpoint, including per-account OAuth and a shared tool registry across clients.

I designed the plugin architecture and tool contracts for Claude, Claude Code, Cursor, and API integrations. I also built streaming Google API transport, resumable attachment uploads, production contract testing, usage metering, Stripe billing, PostHog analytics, and an internal agent-powered operations assistant.

Engineering Manager, Platform Nativo Inc.

I manage the Platform team responsible for Nativo's administrative platform, including hiring, one-on-ones, planning, and technical direction. I own the team’s Jira process and coordinate platform work with product, design, stakeholders, and other engineering teams.

I worked directly with the team to ship custom cookieless audiences under a fixed launch date. I also introduced Wizy, the platform’s first visual builder, and helped define and prioritize the platform roadmap.

Technical Lead, Self Serve and Platform Nativo Inc.

I led the self-serve engineering team, supporting pair programming, feature decomposition, ticket planning, and stronger team communication. I helped guide platform delivery across frontend and backend work.

I won two internal hackathons; the second became ContentAI, Nativo’s first AI-driven creative-generation feature, which I led into production using Vue, Tailwind CSS, Python, and OpenAI. I also integrated ReadMe, Pendo, and SendGrid and led the migration from the legacy email system to SendGrid.

Senior Software Engineer (Contract) Equinix

I built the user interface for a requests-management page used to request server racks and data rooms. The interface included table views, change logs, and ticket attachments.

I used React, GraphQL, and Zustand to deliver the feature as part of a remote contract engagement.

Lead Software Engineer Open Raven

I contributed to the cybersecurity product developed by the team during the company’s Series B period. My work spanned backend services and frontend application development.

I built an API service for managing Amazon S3 instances using LoopBack on Node.js and worked on the React and Redux frontend.

Senior Software Engineer, Admin / Ad Server Client Nativo Inc.

I created and owned NucleusUI, Nativo’s first Vue.js UI component library, which was adopted across all client-facing products. I also helped build version three of the administrative product, including campaign, budget, and ad editors.

I re-architected the administrative client from Angular to Vue and introduced updated build tooling with Webpack and Jenkins. I was also the sole client-side developer for Native Stories, an Instagram-style story advertising format.

Senior Software Engineer, Platform UI Cornerstone OnDemand

I was the main developer of Player.JS, a UI framework for application developers. It included a JSON layout language, a JSON-to-React compiler with schema validation and live reload, a Yeoman scaffolder, and a VS Code extension with validation and autocomplete.

I built the Controls Portal using React Storybook, integrated Karma and Jasmine tests into TeamCity pipelines, and ran workshops while writing extensive framework guides and standards documentation.

Software Engineer, Controls Cornerstone OnDemand

I built the UI for AppBuilder, a drag-and-drop tool for composing web applications from Cornerstone controls. The product was demonstrated at the company conference.

I used React, Redux, and TypeScript and championed the transition from a .NET templating engine and jQuery widgets to React and Redux. I also created the first Controls Portal.

Full Stack Developer Kareo, Inc.

I was the main developer for kareo.com, working across full-stack web development. I developed features using .NET MVC and jQuery widgets.

I also implemented integrations with Google Maps and LivePerson.

Intern Developer Kareo, Inc.

I developed a practice-management advertising widget and a resource hub for EHR customers. This role provided early experience delivering customer-facing web features.

I also created HTML email templates and contributed to product-related web development work.

Junior Web Developer Jazel, Inc.

I developed automotive dealer websites using Orchard CMS. I contributed to web implementation work for dealership clients.

This role established my early professional experience in web development and CMS-based site delivery.
