About

Professional summary

Principal Software Engineer & Founder with 15 years of experience building web applications for startups and large tech companies.

Frontend-focused full-stack engineer (React / TypeScript / Node) specializing in AI-powered products and agentic workflows. I run Kwantum Tech, a contract software studio in Miami, where I design and ship production-grade software for clients — from polished, high-performance interfaces to distributed backends.

My focus today is AI: LLM API integration, AI agents, and agentic workflows that turn language models into real, reliable products. I pair deep frontend craft — 7+ years in React, 7 in TypeScript — with full-stack delivery: Node.js backends, Cloudflare Workers at the edge, and Python services. Products ship fast, with the polish and engineering rigor to hold up at scale.

Remote-first. Open to contract and full-time roles. US-authorized with no sponsorship needed, and available immediately.

Career history

Principal Software Engineer & Founder Kwantum Tech

I own and lead a software engineering consultancy delivering custom web and mobile products, AI agents, workflow automations, and private internal tools from discovery through production.

I build AI employee solutions for realtors and wellness studios, conduct AI audits to identify and eliminate repetitive work, and deliver agentic solutions for finance, crypto, luxury, and healthcare clients. I built CHAD v2, a financial-market trading engine deployed on Cloudflare Workers using an AI-agentic coding workflow.

Senior Software Engineer Fanfix

I led frontend architecture for the V2 web application serving approximately 3 million monthly users and 50,000 creators, using React, GraphQL, and AWS.

I built a reusable Storybook design system with more than 75 components, reduced website startup time by 72% through performance optimization, and shipped live-streaming experiences that became a core creator feature. I also mentored three frontend and full-stack engineers and helped ensure WCAG compliance across the product.

Senior Software Engineer Palo Alto Networks

I built a new analytics dashboard from scratch for the Prisma Access team in eight months during a high-growth period for a platform serving millions of users. I developed React and TypeScript interfaces for security analytics and platform workflows.

I created reusable Storybook components with React Testing Library coverage for shared platform UI and managed complex application state with Redux across data-driven analytics experiences.

Senior UI Developer Cisco

I engineered user interfaces for Cisco's Small and Medium Business division using React, JavaScript, and Backbone.js.

I implemented and maintained test coverage for new and existing SMB portal features while collaborating with cross-functional product teams.

Front End & Web Applications Developer Apple

I delivered pixel-accurate, responsive frontend experiences for Apple.com across devices, browsers, and platforms, supporting one of the world's most visited retail sites. I also implemented product-launch features, reusable marketing experiences, and email campaigns.

For Apple University, I developed single-page applications that improved operational and support workflows. I designed and built a student enrollment application using JavaScript, Backbone MVC, REST APIs, and JSON.

Interactive Developer Sapient

I built microsites, landing pages, mobile experiences, and email campaigns for clients including Citigroup, Mars, Dove, Chrysler, Burger King, and BBVA.

I partnered with creative, project, and backend teams to deliver HTML, CSS, JavaScript, jQuery, and mobile web experiences for iPhone, iPad, and Android.
