I design the schema, build the API, spin up the infra, then wire the frontend. Most comfortable when the hard part is the data layer, not the UI.
Framework → database → message layer → infra. Every layer owned, not outsourced.
I start every project at the schema — get the data model right and everything else becomes easier. APIs are contracts, not afterthoughts. Queues and brokers handle what HTTP wasn't designed for. The frontend exists to surface data cleanly, not to own the business logic.
Three production systems across property, healthcare, and clinic verticals.
Integrated property & real estate management information system. Handles the full lifecycle from project management and unit selection to billing, AR/AP, general ledger, and mobile financial reports — used across multiple companies and projects from a single system.
Digital platform powering a women-exclusive skin clinic chain across Indonesia. Covers online reservations, patient management, skincare e-commerce, treatment catalogues, and a companion mobile app (HayyuDoc) on Play Store & App Store — with GCS-backed media storage at scale.
Operating system for modern healthcare clinics. Unifies clinical documentation, appointment & patient flow, prescriptions, treatment plans, inventory control, doctor commissions, and real-time performance reporting — HIPAA & GDPR compliant, built for multi-specialty environments.
