Uses
The toolchain behind the work.
What I use every day to build, ship, and operate AI systems, and what each tool is for.
01
Coding agents
Most of my code is written with agents and reviewed by me. The skill is in the specs, the tests, and the review.
- Codex
- Parallel branches and reviews. Hundreds of codex/* branches across the DeepChamp repositories.
- Claude Code
- Long-running build, debug, and release sessions, steered by repository rules files.
- Cursor
- Editing and quick refactors inside the IDE.
02
MCP servers
Agents operate real systems through MCP instead of screenshots and copy-paste.
- App Store Connect
- Builds, versions, review notes, and subscriptions.
- Firebase
- Auth, Firestore, and project configuration.
- Stripe
- Products, prices, and webhook debugging.
- AppsFlyer and Superwall docs
- Attribution and paywall reference while building.
- OpenAI developer docs
- API reference inside the agent's context.
03
Models
Each model has one job, and code owns every threshold.
- OpenAI
- Real-time voice over WebRTC, conversation and tool orchestration, evidence-gated expert reasoning.
- Gemini
- Grounded research, structured output, and Live narration.
- Amazon Bedrock
- An opt-in reasoning path with a fallback chain.
- TypeSafe Jev
- Typed, calibrated judgments: scores, choices, and yes-or-no probabilities with confidence.
04
Cloud and data
Boring, observable infrastructure, so the interesting parts can move fast.
- Google Cloud
- Cloud Run, Cloud Functions, Cloud Scheduler, and Spot VMs.
- Firebase
- Auth, App Check, Firestore, and Crashlytics.
- BigQuery and Dataform
- The warehouse, with assertions and freshness targets.
- Vercel and Next.js
- Web apps, dashboards, and this site.
05
Apps and media
Native where it matters, and media pipelines that run unattended.
- SwiftUI and StoreKit 2
- Native iOS apps, widgets, Live Activities, and subscriptions.
- Superwall
- Paywall experiments with holdouts.
- ffmpeg, Demucs, Essentia
- Audio analysis, rendering, and five-hour film encodes.
- Remotion and HyperFrames
- Lyric videos and product films rendered from code.
06
Quality
Nothing ships on vibes.
- pytest, XCTest, node:test
- More than 17,000 automated tests across app, services, and warehouse.
- Eval harnesses
- A voice autograder and a text eval catalog with a grader.
- Deploy gates
- Deploy scripts that stop on the first failing test.
