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.

2 apps on the App Store No ads, no tracking On-device processing

Published apps

Both are free downloads on Apple's App Store, published under my own developer account.

DocAura

iPhone & iPad · iOS 16.0 or later · Free
On the App Store

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

Mac · macOS 14.0 or later · Free
On the Mac App Store

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

Desktop · In development
Not yet released

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.

TypeScriptVS CodeMIT

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.

PythonRAGLocal models

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.

EvaluationRetrieval

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.
