Extended project index.Architecture, products & applied R&D.
The homepage contains the primary portfolio evidence. This page covers additional systems that still demonstrate useful engineering judgment: enterprise architecture, developer tooling, enablement, focused product delivery and interaction research. Projects are separated by maturity rather than presented as equally finished products.
AI architecture, enterprise systems & developer tooling
Work where architecture, workflow design, evaluation, governance or operating constraints matter more than a consumer-facing launch. This is also where engineering overlaps most strongly with technical consulting.
- OrbitAn anonymized demand-intake architecture with requestor, operations and governance surfaces, explicit lifecycle rules and auditability.
Stack: Next.js 16 · React 19 · TypeScript · Upstash Redis · Vitest · dependency-cruiserEnterprise prototype→ - ReqForgeAn early AI requirements pipeline that evolved from a questionnaire into generated requirements, stories and test artifacts — including the schema failures that informed later contract-first systems.
Stack: Next.js 14 · Firebase · OpenAI Assistants · typed schemas · pnpmResearch case→ - AI Requirements Engineering PlatformAn anonymized enterprise generation pipeline for traceable requirements, epics, stories, tests and technical specifications with grounding, human review and quality gates.
Stack: Next.js · React · BullMQ · Azure OpenAI · Cosmos DB · Elasticsearch · RedisAnonymized enterprise case→ - AviaLintLocal-first AI code review for arbitrary workspaces with SCM abstraction, optional CI integration and SonarQube-assisted quality views. Presented without employer-specific implementation details.
Stack: Python · local Git/filesystem · pluggable LLM access · SonarQube · CI adaptersPrivate developer tool— - Intelligence DeskA local-first research radar for collecting signals, analyzing them through structured learning workflows, discovering related material and exporting briefings to a personal knowledge system.
Stack: Python · local MLX models · browser client · web research · Obsidian exportPrivate MVP— - AI Nexus Enablement PlatformHands-on AI and RAG enablement environment with executable exercises, quizzes and browser-based Python notebooks. Designed for practical capability building rather than slide-only training.
Stack: JavaScript · HTML/CSS · Pyodide · Markdown content · notebook-style executionEnablement platform—
Products & focused delivery
Smaller products with a clear interaction loop and narrower operating scope. They remain useful evidence because they demonstrate shipping discipline without being presented as flagship systems.
- Agile PokerRealtime planning-poker utility for distributed teams with room state, voting and facilitation interactions.
Stack: React · Firebase · Framer Motion · Fabric · i18next · TailwindProduction utility↗ - QuizWorld / QuizaruMultiplayer quiz system with generated questions, realtime rooms and a test suite that evolved alongside the game loop.
Stack: Node.js · Express · PartyKit · Socket.IO · Vitest · AI question generationPublic prototype↗ - Stadt Land FlussRealtime multiplayer version of the classic word game, optimized for low-friction browser rooms without mandatory accounts or installation.
Stack: PartyKit · WebSockets · browser multiplayerLive experiment↗ - WikiReaderMobile Wikipedia reader combining search, offline reading, speech and AI-assisted rewriting / key-point extraction — an earlier precursor to later explainer systems.
Stack: React Native · Expo · Firebase · OpenAI · AsyncStorage · Expo SpeechEarlier mobile product↗ - Hannover WischtProduction service website and conversion funnel with a deliberately narrow engineering objective: clear information architecture, responsive delivery and lead conversion.
Focus: client delivery · responsive UX · conversionClient delivery↗
Applied R&D & interaction systems
Experiments built to answer a technical or interaction question: physical input, deterministic generation, collectible systems, motion control and visual treatment.
- Barcode BattlerTurns physical barcodes into deterministic collectible creatures, then uses them in an auto-battler, asynchronous PvP and territory layer.
Stack: SwiftUI · AVFoundation · CryptoKit · GameKit · CloudKit · MapKitGame R&D→ - Masterpiece CollectorA collectible interaction system built around real artworks, museum metadata, rarity, epoch-specific art direction and custom holographic treatments.
Stack: React · Vite · TypeScript · museum APIs/IIIF · image preprocessing · FirebaseInteraction R&D→ - Head Keep-UpA focused sensor experiment that treats headphone motion as a controller, with a minimal visual surface and spatial audio feedback.
Stack: SwiftUI · CMHeadphoneMotionManager · AVFoundation · custom game physicsInteraction spike→ - WallChessA chess-adjacent rules experiment exploring how one additional spatial constraint changes a familiar system without replacing its underlying mental model.

Portfolio policy
The homepage contains primary evidence. This index contains secondary work with differentiated maturity. Forks, backups, support repositories and abandoned spikes stay outside the portfolio unless they demonstrate a specific contribution or engineering lesson.
