FULL-TIME
FULL-STACK SOFTWARE ENGINEER
@ TSN · 1+ Years
- -Lead full-stack developer on three multi-tenant B2B SaaS platforms (a school management system, a freight & delivery operations platform, and a repair-shop POS), all on a shared Next.js / React / TypeScript + Express + Supabase stack
- -Designed multi-tenant, campus- and branch-scoped data models with authorization enforced at the database through PostgreSQL Row-Level Security instead of application code
- -Built server-side PDF pipelines with Puppeteer for report cards, certificates, ID cards, and fee receipts, driven by visual template designers
- -Implemented an append-only, trigger-enforced shipment event log so the delivery timeline is a tamper-proof audit record, with live tracking on a Mapbox GL map
- -Modeled money-handling flows (split tender, partial refunds, trade-ins, deposits) as PostgreSQL RPC functions so cash-drawer and P&L stay correct across every payment path
- -Integrated Stripe billing (tiered plans, per-tenant module entitlements, webhooks) and dynamic RBAC encoded into the JWT so every route and control renders against the current permission set
- -Covered 100+ REST resource groups across academics, finance, HR, scheduling, inventory, and inspections, backed by ~215 versioned SQL migrations on the POS alone
