Full-stack product engineer with backend depth and UX judgment
I help teams turn complex product ideas into maintainable software across backend systems, integrations, frontend workflows, and UX-minded delivery.
Open to senior full-stack product roles, selected product work, and technical collaborations.
Current focus
APIs, AI flows, payments, and workflow tools that stay understandable after launch.
Reliable APIs, business logic, data models, and product workflows that stay readable as the platform grows.
Chat flows, AI services, and third-party APIs connected to real product behavior instead of isolated demos.
Stripe checkout logic, webhook handling, reconciliation concerns, and internal workflows around payment states.
I care about usable flows, clear interfaces, and backend decisions that support the product experience.
Selected work
Readable case studies for recruiters, engineers, and product teams: what the product needed, the ownership signal, and the practical outcome.
Backend foundation for a social product with user accounts, content flows, activity tracking, and product logic.
Outcome: Improved backend maintainability by separating social workflows, API behavior, and data access into clearer modules.
Backend development for a product using AI chat features, service orchestration, and payment flows.
Outcome: Improved AI workflow reliability by separating orchestration, payment eligibility, and user-facing state into clearer backend boundaries.
Backend development for a product using AI chat features, service orchestration, and payment flows.
Outcome: Created a more maintainable backend foundation for AI-enabled product workflows.
Product Labs
Selected product labs showing product taste, UX thinking, visual direction, and full-stack execution outside company work.
Product Lab
Social product for anonymous emotional connection and real feelings.
An anonymous peer-to-peer mental health support application designed to create genuine connection without the pressure of traditional social media.
Product Lab
Relationship-management product for meaningful connection tracking, emotional context, and smart reminders.
A personal CRM reimagined for genuine relationships, combining contact history, relationship health visualization, and mood-based journaling.
My Philosophy
How I approach building web products that stay understandable and maintainable long after launch.
I understand what users and operators actually need before drawing database schemas or writing controllers.
I favor explicit domain models, predictable API payloads, and robust tests over hyper-abstracted design patterns.
I active-monitor error tracking, optimize database indexing, and write migration scripts that don't lock tables in production.
I bridge the gap between design and system constraints, identifying UX edge cases and performance trade-offs during wireframing.
