AI Engineer building agentic AI & LLM apps — multi-agent systems, RAG, evals — on a full-stack foundation of TypeScript, React & Node.js.

AI Engineer building agentic AI and LLM applications — multi-agent systems, RAG, and eval-driven quality — on top of a full-stack foundation in TypeScript, React, and Node.js. Most recently took a construction-management AI assistant from a single-prompt call to a shipped multi-agent system on Mastra and the Vercel AI SDK. 3+ years shipping production web apps, plus a Master of Science in Information Technology from Concordia University (Dec 2025). Open to AI engineering and full-stack roles across Canada.

About

I'm an AI engineer based in Canada, building agentic AI and LLM applications on top of 3+ years shipping production web apps across freelance, internship, and full-time roles.

Lately I work on multi-agent systems, RAG, cost-aware model routing, and human-in-the-loop tooling with the Vercel AI SDK and Mastra — and I hold quality with golden-set evals and per-turn tracing. It's all grounded in a strong full-stack foundation: TypeScript, React, Next.js, Node.js and NestJS.

I recently completed an MSc in Information Technology at Concordia University and I'm open to AI engineering and full-stack opportunities across Canada.

Experience

  1. Full Stack / AI Engineer (Contract)

    Apr 2026 — Present

    Scale Dev·Edmonton, AB · Remote

    • Owned an AI product surface end-to-end for a construction-management (AEC) platform, taking the assistant from a single-prompt LLM call to a shipped multi-agent system on Mastra and the Vercel AI SDK (Next.js, TypeScript).
    • Designed multi-agent routing: a cheap classification step analyzes each query, a router delegates to dedicated per-module agents (punch list, observations, site logs, notes, settings), fans out across modules when a question spans several, and synthesizes one streamed answer.
    • Optimized LLM interactions and retrieval with RAG-style grounding over project documentation, tuning for accuracy, latency, and cost together.
    • Implemented cost-aware model tiering that routes queries to nano / mini / frontier models by complexity — with a hard rule that writes never run on the cheapest tier — cutting cost per query without sacrificing accuracy on hard, multi-module questions.
    • Built human-in-the-loop writes: the model proposes mutations rather than executing them, streaming a tool call the UI renders as a confirm card so nothing changes without explicit user approval.
    • Built a golden-set evaluation harness (routing accuracy, refusal safety, tool selection, agent dispatch) that runs against live models, plus per-turn tracing of latency, tokens, and model mix — catching regressions before users hit them.
    • Shipped behind feature flags alongside the existing assistant, with zero disruption to the live product.

Construction Field & Punch-List Management Platform

Real-time, offline-first platform for construction field teams.

Built a web platform for construction teams to manage punch lists, field observations, floor-plan markups, and site logs across multiple projects. The app supports real-time collaboration, offline-first data capture on job sites, and deep-linked notifications, with a Figma-driven design system for pixel-perfect, fully internationalized UI.

Key contributions
  • Led development of the punch and observations modules, delivering end-to-end workflows for creating, assigning, and tracking field items with optimistic updates.
  • Implemented an offline-first architecture using IndexedDB so field crews can capture data without connectivity and sync seamlessly when back online.
  • Engineered interactive floor-plan markups with Leaflet and a pin-based annotation system tied to punch items.
  • Integrated real-time updates via Ably and reliable notification deep-links that open detail panels directly.
  • Enforced a Figma-first design token system and full i18n coverage across every user-facing string.

Self-Hosted Image Optimization Platform

A local-first alternative to imgix / Cloudinary.

Built a self-hosted image optimization platform (a local alternative to imgix/Cloudinary) that lets users upload images, queue asynchronous transformations, store renditions, and serve them with caching. The system gives teams full control over their media pipeline without relying on third-party services.

Key contributions
  • Architected a monorepo with Turborepo, separating the shared database layer (@repo/db) from the Hono-based API for clean, reusable boundaries.
  • Implemented dual-mode authentication with Better Auth, supporting both session cookies and API keys through a single unified guard.
  • Designed a type-safe domain model (Product → Media → Variation) using Drizzle ORM with schema-driven migrations as the single source of truth.
  • Built self-documenting REST endpoints with @hono/zod-openapi, serving an OpenAPI 3.1 spec rendered through Scalar at /docs.
  • Containerized the full stack with Docker Compose, orchestrating database, migrations, and API startup for one-command local deployment.
