What I'm doing now.

Shipped: Prism Runner 5.0, fully native

The Swift, SpriteKit, and Metal rebuild I spent the spring on is out — version 5.0 landed on the App Store↗ in June as the biggest update in the app's history. Because the rewrite mutated the existing Xcode project in place, the bundle ID, entitlements, and purchases all carried over: existing players got a whole new engine as a regular over-the-air update.

The world got rebuilt along with the runtime. Runs now travel through twelve hand-painted biomes — Nebula Drift, Crystal Cave, Void Storm, Cherry Blossom Garden, Kelp Forest — connected by cinematic transitions, each with its own music and signature hazard. New dimension powers (Hyperdrive, Shield, Magnet), Prism Mode at a 10× combo, all at 120fps on ProMotion.

Now comes the fun part: watching what players actually do with it, and writing up how an in-place native rebuild goes when you ship it as just another update.

TripChronos 2.1: import a whole trip at once

Also just shipped. The headline feature is Import Photos by Date — pick a trip's dates and the app gathers everything you shot in that window for one-step review, no more scrolling the camera roll. Under the hood: much faster imports and smoother scrolling in trips with thousands of memories.

Still experimenting with smarter scene selection for the trip-video pipeline: letting the app pick a tighter highlight reel out of a 2,000-photo trip without you having to curate.

Experimenting with AI-assisted development

Both of those launches were built AI-first, and I'm going deeper on the practice itself: prompting techniques, spec-driven workflows, and agent patterns — what it takes for coding agents to build reliably, and how the developer's job shifts toward architecture, judgment, and review when they do.

Building, not just reading. I open-sourced ragcli↗, a "RAG-in-a-Box" CLI for chatting with your documents from the terminal, and I'm running a document retrieval and Q&A service on FastAPI, PostgreSQL with pgvector, and Redis workers, with large-scale embedding workloads on AWS Bedrock.

Less interested in chasing the model-of-the-week, more interested in the parts that will still feel useful in twelve months.

AWS, passport stamps in progress

AWS Certified Cloud Practitioner↗ in hand; currently working through the Developer Associate study path. Deeper into IAM, Lambda, DynamoDB, and the bits of the platform I want to lean on for side-project backends.

Otto things, travel things

Trying to take Otto somewhere new at least once a month. He has opinions about rest stops and is generally correct about them.
