Industries
Main areas of expertise
I've built software across healthcare, financial services, e-commerce, education, and enterprise operations. My experience ranges from customer-facing products and marketplaces to data-intensive platforms, internal tools, distributed workflows, and highly regulated systems.
Healthcare & Clinical Data Platforms
I've built healthcare products ranging from telemedicine and benefits marketplaces to patient encounter management and privacy-preserving research platforms. This work includes HIPAA-compliant infrastructure, FHIR and OMOP data workflows, clinical integrations, asynchronous processing, consent-aware access, and secure handling of sensitive health information.
Financial Services & Asset Management
I've developed data-intensive applications for asset management, structured finance, and legal and financial operations. These systems include financial analytics, benchmarking, complex search, secure document delivery, third-party integrations, and internal tools where performance, permissions, and data integrity are business-critical.
E-commerce, Marketplaces & Ordering Systems
I've delivered high-traffic e-commerce experiences, healthcare marketplaces, and white-label food-ordering platforms used across multiple restaurant brands. My work covers checkout modernization, product discovery, payment flows, third-party ordering services, and scalable customer-facing applications.
Enterprise Platforms & Workflow Management
I've worked on enterprise systems that help organizations manage projects, resources, content, and operational workflows. This includes modernizing Adobe Workfront, evolving legacy applications, building internal administration tools, and integrating platforms used across complex business processes.
Education & Accessible Learning Platforms
I've contributed to e-learning products and reusable component systems designed for inclusive digital education. The work involved accessible interfaces, component-driven development, Storybook workflows, responsive experiences, and support for users across different devices and assistive technologies.
Developer Tools, Documents & Interactive Products
I also build specialized digital products, including developer utilities, document-processing applications, PDF experiences, and interactive browser-based tools. These projects range from secure environment management and native developer dashboards to fiscal-document workflows, advanced vector editing, and data-driven browser games.
These industries and product types represent the strongest areas of my experience, but they are not limits. I'm comfortable entering new domains, understanding their workflows and constraints, and applying the same product-focused engineering approach to unfamiliar challenges.
