What I Do

I specialize in full-stack application development, AI implementation, technical leadership, and ecommerce systems.

Full-Stack Web Development

I build complete, scalable, and high-performing applications. With expertise in JavaScript, React, Next.js, Node.js, Vue.js, and Python, I deliver strong user experiences on the front-end and reliable systems on the back-end.

Ecommerce Development

I design ecommerce systems that grow with your business. With deep specialization in Salesforce Commerce Cloud and strong Shopify experience, I build integrations, improve performance, and connect the tools that support better operations and customer experiences.

I build practical AI tools for products and teams. From conversational interfaces and workflow automation to AI coding support, agents, skills, and prompt design, I help teams adopt tools like Codex, Claude Code, and GitHub Copilot with clarity and execution.

Technical Consulting & Modernization

I help teams modernize legacy systems, shape new platforms, and make better technical decisions. Whether the work involves cloud applications, integrations, or delivery practices, I bring practical guidance that helps teams move forward.

Technical Leadership & Consulting

I partner with companies that need hands-on leadership, faster execution, and clearer technical direction.

Engineering Team Foundation

Startups and growing teams bring me in to establish workflows, documentation, delivery habits, and technical standards. I work hands-on early, help unblock the team, and create a foundation the internal team can take forward.

Custom Application Development

When a client has a strong product idea but needs senior execution, I help shape the roadmap and build the system. From discovery and prototyping to architecture, development, and launch, I guide the work in a practical, collaborative way.

Solutions Architect

For teams facing complex technical or organizational challenges, I step in as a Solutions Architect. I lead discovery, clarify tradeoffs, and map technical strategy across product, design, and engineering so teams can move forward with confidence.

Prototype to Production

When speed matters, I help teams move from prototype to production without losing sight of scale, security, or maintainability. Fast iteration, direct feedback, and clear priorities help turn early concepts into working systems.

Leadership Background

My leadership style was shaped by roles that demanded accountability, empathy, and operational clarity.

Retail Store Management

Early on, I managed multiple retail stores, leading teams of 8-10 employees in fast-paced environments. That experience taught me how to coach people, improve customer outcomes, and keep teams aligned under pressure.

Assembly Line Operations Management

At SkyLine, I supervised an assembly-line facility of around 90 employees, focusing on throughput, process improvement, and team support. Building inclusive programs for employees with cognitive and physical disabilities deepened my commitment to people-centered leadership.

Development Team Leadership

At Answers.com, I launched and led the company’s first mobile development team, helping the business move early on mobile and significantly grow traffic. It sharpened my ability to build teams, prototype quickly, and align engineering work with product goals.

Chief Technology Officer

As CTO at Enroll123, I led technology strategy and delivery in a regulated health insurance startup, including HIPAA and HiTECH compliance. The role strengthened my ability to balance architecture, risk, execution, and cross-functional decision-making in high-stakes environments.

The right technical lead can change the trajectory of a project.

Experience in Action

I’ve led work across ecommerce, civic tech, nonprofit platforms, and mission-driven products.

Google Jigsaw: User in Residence

I was invited to consult through Google’s “User in Residence” program, sharing insights on civic technology, public data accessibility, and responsible platform design. The work reflected the kind of strategic, high-context discovery a Solutions Architect brings to complex initiatives.

Nike Skateboarding & Snowboarding

As the Solution Architect and Full-Stack Developer, I built a custom platform for Nike’s action sports brands years before modern ecommerce platforms were standard. I designed the data model, CMS, and caching systems that helped the experience scale globally.

Civil Services: Open Data for Activism

I founded Civil Services to make elected official data accessible, accurate, and API-ready for civic tech. With 400+ volunteers, we built a geolocation platform that helped activists connect with representatives by turning complex public data into reliable software.

Gigoit.org: Giving Tech a Purpose

I co-founded Gigoit.org, a nonprofit platform that helped more than half a million people keep unwanted items out of landfills. Recognized by the U.S. EPA and featured in major publications, it remains one of the clearest examples of software with measurable real-world impact.
