I ship agentic AI that engineering teams actually adopt. Not demos. Not pilots that quietly die. Things that stay shipped. ## Experience — The story so far ### Making AI do the boring parts *Now · Marvik → dLocal* Embedded in dLocal's AI team, where I ship agentic systems on a Claude Agent SDK / Claude Code base. The one that rolled out across the engineering org drives 40%+ end-to-end automation of dev tasks on a high-availability fintech platform. People stopped asking "does this help?" and started asking "how did we work without it?" Tags: Claude Agent SDK, Python, Metaflow, Kubernetes ### AR, AI, and a Fortune 500 *Four years · Ulta Beauty · Innovation* Contributed to GLAMlab — Ulta's AR/AI virtual try-on and its first public generative AI app. Built a video analysis engine that watches affiliate and influencer content for brand-guideline violations at scale. Plus supporting iOS, web, and backend work across innovation projects. Tags: Google ADK, Computer Vision, Swift, React ### Running a bookshop with code *Alongside · BroLi · Co-founder* Co-founded and led engineering at an independent bookshop that applied blockchain and AI to a category that usually ignores both. Owned the stack end to end, led a small team, learned that startups are 20% code and 80% everything else. Tags: Blockchain, NLP, Team Lead ### Teaching, shipping, learning *Earlier · Universidad de Montevideo · Octobot* Taught innovation and life-design workshops at UM's corporate innovation lab. Before that, shipped Django/React web and Swift/SwiftUI iOS at Octobot. The teaching part stuck — I still think of great engineering as mostly good explanation. Tags: Teaching, iOS, Full-stack ## Skills - **I think in**: Python, Swift, TypeScript. - **I build agents with**: Claude Agent SDK, Claude Code, LangGraph, Google ADK. - **I make AI useful with**: RAG, Knowledge Graphs, NLP, Computer Vision. - **I ship on**: Kubernetes, Metaflow, Docker, Vercel. ## Projects — Things I've built > The projects that taught me the most — or that I just can't stop talking about. ### [Seniorify.dev](https://teams.seniorify.dev/) 🏆 1st place at the Montevideo edition of Vercel's "Zero to Agent" Hackathon. A senior-in-the-loop for AI coding agents — intercepts PRs before they're written and interrogates juniors on their architecture choices, so they understand the why and not just the what. Tags: AI, DevTools, EdTech, Next.js ### Phex 🏆 1st place at the 2025 AI Hackathon (Microsoft AI Co-Innovation Lab × INGENIO, BASF challenge). An agentic AI safety copilot for chemical plants — modular, real-time, and watches operations on video to flag risk before productivity, safety, or sustainability take the hit. Tags: Agentic AI, Computer Vision, Industrial Safety ### [Startup in a Box](https://startupinabox.martinbrian.com) Two AI architectures walk into a room and build a startup — Google ADK plans, Claude Agent SDK builds. Open source; the live link is a UI preview, so clone the repo to run the full stack. Tags: Claude Agent SDK, Google ADK, PixiJS, Next.js ### dCoder At: dLocal (production work owned by the company) The agent system that changed how dLocal's engineering org works — model-agnostic agents handling code reviews, test generation, and routine dev in production on fintech rails. Drives 40%+ end-to-end automation of dev tasks. Tags: Claude Code, Python, Kubernetes ### GLAMlab At: Ulta Beauty (production work owned by the company) Ulta Beauty's AR/AI virtual try-on — millions of users on iOS and Android, and the company's first publicly-recognized generative AI application. Tags: AR/VR, Swift, iOS ### Brand Compliance Engine At: Ulta Beauty (production work owned by the company) Watches thousands of influencer videos and flags the ones that break the rules — competitor mentions, quality issues, policy violations. Built to replace a team squinting at screens. Tags: Computer Vision, NLP, Python ## Talks & demos > I explain agentic AI on stage — usually live, usually with something deploying in real time while I talk. Full talks index: https://talks.martinbrian.com (each talk has its own subdomain). ### [Greenfield Development with Claude Code](https://greenfield.martinbrian.com) From vibes to engineering — a decision framework for building with AI agents, run as a live audience game.

The demo is a deployed UI preview; clone the repo to run the full multi-agent pipeline.
