Thoughtware POS Ecosystem
A production point-of-sale ecosystem I architected and built from scratch at Thoughtware over ~4.5 months: a core POS app plus companion apps that share one FastAPI/MSSQL backend.
- Core POS app (solo): order/payment flow, floor-plan & table management, staff/PIN permissions, offline-resilient sync, and a first-run setup wizard
- Real-time layer: JWT auth with automatic token refresh and a WebSocket event bus (FastAPI + asyncio) keeping every terminal, kitchen display, and customer display in sync
- Two-phase commit & startup reconciliation job that closed a data-loss window on payment completion
- Companion apps built from scratch: customer display (scan-to-pay, email receipts), manager reporting dashboard, and a back-office admin hub (React / Vite / TypeScript)
- Backend contributions: combo/discount engine, seat-level billing, shift management, and the real-time event API

AI Context Infrastructure
A persistent AI context layer for a multi-repository SaaS ecosystem (8 applications, ~90 API routes) that gives developers and AI agents structured, source-verifiable knowledge to reason about dependencies, business logic, and change impact.
- Layered knowledge architecture: high-level summary → service-specific reference → in-depth technical analysis, with source-based confidence ratings to cut hallucinations
- Coordinated parallel AI research agents to cross-verify a large multi-service codebase and map cross-service dependencies
- Result: faster feature development, more accurate AI-assisted code generation, and lower onboarding cost for new developers
