Product engineering
From an unclear business problem to a system people can actually use — requirements, trade-offs, interfaces, APIs, and delivery included.

I build things.Mostly software.
Always with intent.
Mobile products, useful systems, and the kind of problems that only show up after everything was supposed to be working.
↓What I do
Engineering that survives contact with reality.
Mobile products
React Native and TypeScript across iOS and Android, grounded in production maintenance rather than framework theatre.
Frontend systems
Next.js, responsive interfaces, motion, transactional communication, and the reusable structure behind polished product experiences.
How I work
Less theatre.
More signal.
Understand before building
The first solution is usually just the fastest way to discover the real problem.
Make the complex legible
Good engineering leaves fewer mysteries behind — in the product and in the code.
Care about the last 10%
Loading, failure, interruption, recovery. The unglamorous states are still the product.

01Popstand
Healthcare operations leadership
Led frontend, backend, and mobile delivery for an international healthcare client. Broke large Jira items into parallel workstreams, more than doubling monthly throughput while preserving peer review and integration quality.
- HL7-based reporting across multiple US states
- Privacy-sensitive laboratory workflows
- Client communication and technical coaching
02Popstand
A simpler way to create on-chain
Built the initial structure of an NFT marketplace across frontend, application APIs, deployment, and stakeholder communication. Designed a validated prototype that presented dependent blockchain operations as one guided creation flow.
- Collection and asset creation
- Third-party Web3 APIs
- Feasibility before premature resilience
03Sortium
Frontend systems with sharp edges
Built responsive, accessible, motion-led interfaces for established and experimental digital products. Designed a composable transactional-email system driven by reusable blocks and backend-provided content.
- Gmail, Outlook, and device validation
- CSS animation and responsive UI
- Registration and error-state ownership
04Entermotion
Production mobile, without mythology
Maintained patient- and provider-facing React Native applications covering scheduling, messaging, forms, notifications, billing, and payments. Supported the mobile tech lead in investigating and validating production bugs.
- React Native and TypeScript
- GraphQL and Apollo Client
- Remote collaboration in English
Specific enough to show the work. Careful enough to respect the people who trusted me with it.
Lab / Experiments
Small ideas.
Sharp tools.
No roadmap.
RPG Session Board
A focused space for shaping tabletop sessions: keeping ideas, moving parts, and the inevitable chaos visible enough to actually use at the table.
Campaign notes deserve better than archaeology.Playdate
A local map for parents looking for places that are genuinely kid-friendly — with useful details about play areas, monitors, age ranges, pricing, and recent experiences from other parents.
Their play. Your date.About
I’m interested in the whole thing.
I’m a software engineer focused on mobile products and complex interactions. React Native is where I spend most of my time, but frameworks are tools, not identities.
I like understanding the system, finding where it bends, and building something simpler, reliable, and pleasant to use.
