Senior Engineer | AI Systems & Agents | Multi-Tenant SaaS | Backend Architecture

I have been shipping production backends for two decades, across Laravel, FastAPI, Next.js, and a handful of stranger stacks (Phoenix LiveView, Rails 8, Elixir, Lua). These days most of my new work sits at the intersection of solid backend architecture and LLM-driven systems: agentic pipelines, MCP servers, RAG over pgvector, multi-tenant SaaS with proper isolation, and the boring plumbing (queues, audit trails, webhook signing, RBAC) that keeps any of it usable in production.

This profile collects the projects I build for myself in the open. Each one stands on its own. A few may move from portfolio into commercial product.

• AI agents and MCP infrastructure. LangGraph multi-agent pipelines, custom MCP servers shipped to npm, embeddable RAG chatbots grounded in private content, and the audit + observability layer underneath.
• Multi-tenant SaaS. Row-level security, HMAC webhook signing, tenant-scoped audit trails, RBAC, billing flows. The skeleton I keep reusing across Storebridge, Slate, Plexus, and LearnLoop.
• Legal and governance tech. CaseFlow runs on Laravel 12 + Filament 3 + Stripe. Quorum is the AI-native sibling: entity graph, AI-drafted resolutions, RAG over corporate documents, realtime collaborative editing.
• Search and aggregation systems. Skylane is multi-provider flight search with WebSocket streaming on Laravel + Reverb.
• Cross-border fintech. ZarPay covers the UK to Pakistan remittance corridor with a native Android sender app and a Next.js operations panel.
• Operational platforms. Rampart is an enforcement-first field service OS: deterministic FastAPI engine for FSM + audit + events, with Gemini-augmented incident command layered on top.

• LangGraph orchestrators with hybrid pgvector + tsvector retrieval, Langfuse tracing, and LLM-as-judge evaluation (Meridian).
• Production MCP servers as a TypeScript monorepo, distributed via npm (MCP Toolkit, three servers: GitHub, Linear, Gmail).
• WhatsApp Business AI agent on the Meta Cloud API with structured tool loops and full Postgres audit (Cue).
• Manifest V3 browser extension that summarizes pages and drafts replies through Groq or Claude (Glean).
• Real-time collaborative document editor on Phoenix LiveView with Claude as a co-author and multi-user presence (Scribe).

Backend. Laravel (PHP 8.3), FastAPI (Python 3.12), Next.js (TypeScript), Phoenix LiveView (Elixir), Rails 8 (Ruby), Go where latency matters.

AI tooling. Claude API (Anthropic SDK), OpenAI, LangGraph, Anthropic MCP, Langfuse, pgvector, structured output via Pydantic.

Data. Postgres with RLS, pgvector, MySQL, Redis, MinIO, Drizzle, Prisma, Filament for admin.

Real-time. Reverb, WebRTC, Phoenix Channels, Server-Sent Events, WebSockets.

Infra. Docker Compose for local stacks, Cloudflare Pages and Workers, AWS, Railway, Fly.io.

Automation. n8n, custom subagent fleets, webhook routers, scheduled job orchestration.

• atrium: Privacy-first AI assistant workspace UI: streaming chat, memory inspection, tool traces, personas, voice. React 18 + Vite.
• n8n-agent-studio: Three production-grade n8n workflows backed by a shared Postgres audit table.
• portfolio-bot: Embeddable RAG chatbot grounded on my portfolio site. Cloudflare Workers AI + Vectorize.
• ai-api-starter: Public FastAPI template for AI integrations. Structured output, RAG over pgvector, multi-LLM routing with fallback, Langfuse observability.

• odooforge: Open-source deployment kit for multi-cloud Odoo with a Claude-powered customer support module.

The full repo list lives over on the Repositories tab.

Production-grade agentic pipelines (Meridian), enforcement-first ops platforms (Rampart), MCP infrastructure (toolkit and protocol experiments), and the next pass on the multi-tenant primitives I keep reusing across SaaS projects. Yeah, a lot of it overlaps. That is the point.
