Membership platform
I built a multi-tenant membership platform for tourism and cultural organizations. It covers purchases, renewals, benefits, eligibility, and the account states that members and support teams need to understand.
Shuhao Pang
Senior Full-Stack Engineer
I build membership, payments, and checkout systems. My work moves between product surfaces, APIs, and cloud infrastructure.
Selected impact
These are public-safe summaries of the work I have done. They focus on the problems, decisions, and outcomes rather than proprietary implementation details.
Payments and subscriptions
I worked on payment and subscription flows across multiple providers. The work included webhook processing, retries, refunds, recovery paths, and the operational tools people use when a payment does not go as planned.
Checkout and operations
I shipped checkout, cart, and transaction workflows that connect frontend state to APIs, asynchronous jobs, and production support. I also wrote integration tests and delivery tooling around the flows that carry the most risk.
Details are intentionally high level. I do not publish proprietary code or internal architecture.
Experience
I have worked across product features, platform behavior, and the operations that follow a release. My current work is concentrated in membership, payments, and commerce.

Technical scope
The tools matter because they are the parts I use to make a product work in production. I keep the list focused on the work I want to keep doing.
Frontend
React, TypeScript, JavaScript, HTML, CSS, accessible UI, and complex interface states.
Backend and APIs
Node.js, REST, GraphQL, service integrations, asynchronous workflows, and payment flows.
Cloud and data
AWS Lambda, DynamoDB, SQS, S3, AppSync, Terraform, multi-tenant systems, and schema design.
Engineering practice
Integration testing, observability, rollout planning, incident investigation, and production debugging.
Public work
Outside my day-to-day work, I build small browser games and keep experiments in public. This is where I share work that can be inspected directly.
Get in touch
I am interested in senior full-stack roles where I can own meaningful product work and stay close to the systems that support it.
