    AutoLeap — Angular SaaS Platform for 5,000+ Auto Repair Shops Across North America
    AutoLeap is a Canadian SaaS platform serving over 5,000 auto repair shops across North America. I've been a core engineer on the platform since before its 2021 launch, with 2,800+ commits across major modules. Modules I've worked on: Workboard 2.0 — the shop's central operations hub for managing daily workflow and job scheduling Repair Orders — the core transactional module handling the full repair job lifecycle Purchase Orders — parts procurement and inventory management workflows Tech stack: Angular (v8 through v19) — the platform has evolved across major Angular versions, and I've worked through multiple migration cycles TypeScript, enterprise-scale component architecture Production engineering at scale — this isn't a small app, it's mission-critical software running the daily operations of thousands of real businesses Beyond day-to-day feature work: One of the things I'm proudest of at AutoLeap is designing and building a 30-agent, 26-command agentic engineering pipeline using Cursor — essentially, infrastructure that lets AI coding agents work safely inside a production Angular codebase without breaking things. This included: Path-scoped rules that auto-enforce security, multi-tenancy, and TypeScript-strict standards depending on which part of the codebase is being touched CI gates (ESLint + custom checks) that block architectural violations before they ship Governance-as-code — decision records (ADRs) that gate what agents are allowed to do, with a full audit trail Fixed real production issues like OOM crashes and thermal throttling caused by agent-driven mass edits, by sharding test runs and capping worker pools This wasn't about "using AI to write code faster" — it was about building the guardrails that let AI agents contribute safely to a live, multi-tenant SaaS product without a human having to review every single line. If you're hiring for enterprise Angular work, long-term SaaS maintenance, or AI-assisted engineering workflows, this project is a strong signal of that range. angular typescript saas enterprisesoftware softwareengineer ai cursor b2bsaas automotivetech frontenddeveloper…
    CultureAI — Full-Stack AI SaaS Platform Built with React, Node.js, MongoDB & Stripe Billing
    CultureAI is a live, multi-tenant SaaS platform I built solo as founding engineer — an AI-powered employee engagement tool used by companies to track team sentiment and culture health in real time. Tech stack: Frontend: React Backend: Node.js Database: MongoDB Payments: Stripe (per-seat subscription billing, proration logic, free-tier credit gating, webhook handling) AI: OpenAI API and Claude API integration for sentiment scoring, with per-tenant token metering and cost control Architecture: Multi-tenant infrastructure with per-tenant data isolation and role-based access control (RBAC) What this project involved: I handled the entire build end-to-end — from system architecture and database design to backend API logic, frontend UI, third-party integrations, and production deployment. This wasn't a template or boilerplate SaaS; it's a custom-built platform designed around a specific problem: helping HR teams and managers understand employee engagement without relying on slow, infrequent survey cycles. Key engineering challenges I solved: Designing a multi-tenant data model that keeps every company's data fully isolated while sharing infrastructure efficiently Building a subscription billing system that handles upgrades, downgrades, proration, and free-tier limits correctly Integrating LLM APIs (OpenAI + Claude) in a way that's cost-controlled per tenant, so usage doesn't spiral unpredictably Building an investor-ready product with a working demo, pitch deck, and real production traffic Live product: app.startcultureai.com If you're looking for a full-stack developer who can take a SaaS idea from architecture to production — including billing, AI integration, and multi-tenant infrastructure — this project is a good representation of that range. saas fullstackdeveloper reactjs nodejs mongodb stripe openai softwareengineer webapp startup b2bsaas…

    This was a full end-to-end build — from architecture and backend logic to billing infrastructure and AI integration — shipped and running in production.
