CampusQ
A coaching-management platform where every tenant gets its own subdomain. Built end-to-end — from Postgres row-level security to the marketing site — so isolation holds all the way down.

I build reactive, signals-first interfaces in Angular and React — and the .NET / Node behind them. 3+ years shipping enterprise systems with an AI-native workflow.

Where the value flows from
// chronological2026 →
- Signals-first features for Certain QMS across the Deviation, Checklist & Handbook modules — per-route NgRx Signal stores, strict TypeScript, OnPush — scaffolded with Claude & Cursor agents.
- Chart.js analytics dashboards with multi-format export — locale-aware Excel, styled Word & inline PDF — plus Quill rich-text editing.
- Dual-auth model: JWT interceptor for internal users, route-scoped OTP sessions for secure read-only external sharing.
- Playwright e2e + Vitest across three apps — AI agents (Claude, OpenCode) generated data factories & flagged coverage gaps; localized UI (no/en, 1,000+ keys).
2024
- Architected & delivered 4 enterprise ERP platforms with Angular 19+, .NET 10, PostgreSQL, Redis and MinIO/S3.
- 900+ typed endpoints, 80+ lazy routes, signal-based state, a recursive permission system and tokenized S3 uploads.
- CI/CD with multi-stage Docker, Nginx and SSH deploys; Clean Architecture, DDD, Modular Monolith and Result patterns.
2023
- Built educational platforms (Plabook, Augie) for international teams.
- 40+ reusable master components powering 2000+ games; Stripe & PayPal payment flows with full validation.
- Contributed Android development in Kotlin & Jetpack Compose (MVVM).

Things I shipped on my own time

npm packages with automated GitHub Actions CI/CD, including ngx-primeng-toolkit — parameterized query/table state, memoized data and reusable utilities. Built for internal use, then released to the community.
