A live Path of Exile 2 build-meta tool. Every hour it reads the top of the ladder through poe.ninja, distills thousands of characters into a ranked list across every league variant (Softcore, Hardcore, SSF, HC SSF, Standard), and lets you Decant a build straight into the game's Build Planner folder in one click — via the File System Access API, with no backend and no tracking.

The pipeline is stdlib-only Python on an hourly GitHub Action that fails safe; the front end is a single hand-built page on its own domain.

Contributed to a custom ROM based on Android 4.0 (Ice Cream Sandwich), working at the bytecode level — decompiling system APKs to smali, then patching and recompiling the framework to add features and tune performance. Released through XDA Developers, where one ROM I worked on passed five million downloads.

A browser tool that takes apart any Android app package — decoding the manifest, permissions, components, and signing scheme entirely client-side, with nothing uploaded. The core is a parser I wrote from scratch for Android's compiled binary XML format (string pool, resource map, typed values), validated byte-for-byte against an independent implementation.

A browser-based network-capture analyzer — drop in a .pcap or .pcapng and it shows a protocol breakdown, the conversations between hosts, and a full packet list. I wrote the parser for both capture formats from scratch, plus the dissection up the stack: Ethernet, IPv4/IPv6, TCP, UDP, ICMP, and ARP.

A static security scanner for Android apps. Drop in an APK and it grades the app A–F — flagging risky manifest config (debuggable builds, exported components), sweeping the contents for hardcoded API keys and secrets, and checking signing weaknesses. Built on the same from-scratch manifest parser as APK Inspector, fully client-side.

Co-founded and built an e-commerce platform for an online-game community — the storefront, an automated instant order-delivery pipeline, and the support tooling that kept it running. Going lower-level, I reverse-engineered the game's client and network protocol to build free community tools — a custom client and a real-time event notifier.

Build and maintain a production website end to end — feature development, user-acceptance testing, and troubleshooting through root-cause analysis to keep the platform stable and on-spec.

Deployed and maintained embedded systems and repaired hardware following strict technical procedures — then translated the deep technical detail into plain language for the people actually using the devices.
