// full-stack engineer & architect · 3.5 years

I own the full stack — PHP/Yii2, REST APIs, and React UI — for systems running 100+ universities.

3.5 years shipping enterprise software end to end: PHP/Yii2 backends, MySQL, REST APIs, and React 19 TypeScript frontends — multi-tenant, audit-grade, built for the systems that run India's national university platform.

// one platform, four modules

Architecture map

Four modules, built largely from scratch, sharing one multi-tenant core. Hover or tap a module to see what it adds on top of the foundation.

Every module inherits the foundation, then layers its own domain logic on top — one codebase, many institutions.

The allocation state machine

An 11-state machine with audit logging at every transition — simplified to the happy path here.

  • Append-only status log — every transition is attributable
