Each project is told the same way: the problem someone had, what I built, and the result.
Repeat After Death
Exploding Soes · Lead Programmer · 2023 – 2026
Problem
Turn Ghost Game, a two-day jam prototype that took 2nd place at the Garena Game Jam, into a full game.
Built
Event-driven gameplay systems, a YAML content pipeline, modifiers, save/load, localization, Steam leaderboards with run replays, and editor tools for the team.
Result
Released on Steam in April 2026, with post-launch updates through v1.0.9.
Volunteers had to find and cut the sermon out of every 2–3 hour service recording by hand.
Built
A one-click desktop app. Speaker diarization, YAMNet audio features and a self-trained XGBoost model find the sermon; it then transcribes it with Whisper and publishes it to the church website.
Result
Mean IoU of 0.967 for sermon boundaries on a 20-recording evaluation set.

Problem
Our church needed a home for weekly sermons, then tools for running events like a free-coffee bar.
Built
A Next.js and Supabase site: sermon articles with Bible-verse tooltips, a multi-station coffee ordering system with a barista queue, push notifications, Bluetooth label printing and analytics, plus potluck sign-ups and event booking.
Ask questions about scripture and our church's sermons, and get answers you can check.
Built
Hybrid graph and vector retrieval on PostgreSQL (pgvector and Apache AGE), LLM-extracted knowledge-graph triplets, source-aware routing, multilingual queries and an agentic tool-calling mode.
Result
Answers cite verse references and sermon timestamps.

My disk kept filling up, and I couldn't tell what was safe to delete.
Built
A Windows disk cleanup tool that shows what is safe to delete and why.
Make a stealth game where you can only see what you can hear.
Built
Shader-driven echolocation (each noise casts 720 rays into a GPU texture so its ring stops at walls), a blind monster that hunts by noise and scent trail, rope-physics dragging and throwing.
C#

Built
A shortest-path finder and map optimizer that predicts the best construction placements and analyzes their effectiveness.
C#
