What I'm looking for

I'm looking to help an early-stage remote team evolve a pilot into a secure, maintainable multi-tenant product, owning work from ambiguous requirements through implementation, release support, and production diagnosis.

At TigerCampus, I deliver and support education SaaS administration workflows for bookings, recurring lessons, records, billing, permissions, reporting, scheduling, and messaging automation.

I build React and TypeScript interfaces backed by Apollo Client, Hasura GraphQL, PostgreSQL, Python/Flask cloud functions, AWS Lambda, scheduled jobs, and third-party integrations. I investigate production issues across UI, requests, logs, database state, and provider responses while designing explicit error states, reversible migrations, and scope-aware data operations.

Previously, I owned industrial platform modules at Mosynx Intelligent Technology and contributed to semiconductor equipment-management systems at Capsio Intelligent Technology. I enjoy helping early-stage teams turn pilots into secure, maintainable multi-tenant products.
