Independent app developer
Small, private apps that do one job properly
I design and build software for iPhone, iPad and Mac, and publish open-source tooling for AI retrieval and developer workflows. My released apps are free, carry no ads or trackers, and do their work on your own device.
Published apps
Both are free downloads on Apple's App Store, published under my own developer account.
DocAura
A document scanner and PDF studio that never touches a network. Scan with automatic edge detection, add a searchable text layer with on-device OCR, extract text from any PDF, print the front and back of an ID on one page at true physical size, and generate passport photo sheets for US, UK/EU, India, Brazil and China formats. Merging, splitting, compressing, signing and watermarking are all included.
PhotoPorter
The simplest way to get photos and videos off an iPhone or iPad and onto a Mac. It shows the full camera roll with real thumbnails, remembers what has already been copied so nothing is imported twice, keeps a Live Photo's still and video paired as a single item, and lets you decide how filename collisions are resolved. Everything stays on your computer.
AI Buddy
A study tool for school assessments. It analyses past papers by grade and subject, surfaces patterns and trends, and generates practice and trend-weighted predicted questions using a small language model running locally with retrieval over the question bank.
Open source
Public repositories on GitHub, mostly around retrieval, local models, and developer tooling.
AI Coder
A coding assistant extension for VS Code: chat with codebase awareness, inline editing, Tab autocomplete, and an agent mode with tool use, across multiple LLM providers.
Enterprise RAG Platform
Multi-format retrieval-augmented generation over PDF, Excel, CSV and web pages, with cited answers and usage tracking. Built on LangChain, FastAPI, Chroma, Next.js and Langfuse.
RAG Chunking Benchmark
A controlled comparison of fixed, recursive, semantic and BM25 retrieval over a 355-page technical book, scored by an LLM judge on faithfulness and relevance.
Act vs ReAct
A proof of concept comparing how language models behave with direct action prompting versus the ReAct reasoning-and-acting framework.
How I build
The same few rules apply to everything I ship.
- On-device by default. If a job can be done locally, it is. DocAura makes no network requests at all; PhotoPorter never sends your library anywhere.
- No accounts, no ads, no trackers. There is no sign-in, no analytics SDK, and no third-party advertising code in my apps.
- First-party frameworks. The Apple apps are built on Apple's own frameworks rather than a stack of third-party dependencies.
- Free to use. Both released apps are free, with no in-app purchases.
- Support from a real person. Email reaches me directly, and I answer.
