01 / scrapegoat

Live price comparison.

Searches Amazon, Best Buy, Walmart and Newegg at once and returns the price, rating and review count from each.

02 / table tennis analyzer

Match analytics from video.

Tracks both players and the ball through broadcast footage, reads the scoreboard, and returns a score chart and a position heatmap.

03 / icy tower

A platformer, and an AI that plays it.

A browser game built without an engine, then a neural network evolved to climb it. Also playable with your hands over a webcam.

04 / plantai

Plant diagnosis from a photo.

Identifies the species, works out what is wrong with it, and writes a treatment plan. React Native, still in progress.

and one more, plus the person who built them

Full-Stack Engineer.

I build systems that survive contact with the real world - flaky sites, noisy video, unreliable APIs.

ScrapeGoat

Live price comparison across four retailers that actively block scrapers

Type a product name and get the price, rating, and review count from Amazon, Best Buy, Walmart, and Newegg side by side, pulled live rather than from a stale database.

fallback extraction stages: 4
retailers supported: 4
slowest scrape, run as a background job: 90s

Table Tennis Analyzer

Turns broadcast match footage into player tracking, score charts, and heatmaps

Give it a table tennis video and it returns an annotated replay, a score chart read straight off the scoreboard, and a position heatmap, with no manual tagging.

models (1 custom-trained): 2
outputs per match: video, chart, heatmap: 3
manual tagging required: 0

Icy Tower - Game & Neuroevolution AI

A physics platformer written from scratch, then a network evolved to play it

A browser platformer built with no game engine, plus a neural network taught to climb it by a genetic algorithm, reaching floor 179 after 2,000 generations.

floors reached by the AI: 179
generations trained: 2,000
game engines or ML libraries used: 0

PlantAI

Photograph a sick houseplant, get a species ID, a diagnosis, and what to do about it

A React Native app that chains two vision models, one to identify the plant and one to diagnose it, then returns a treatment plan.

chained vision models: 2
external APIs orchestrated: 5
surfaces sharing one core: 4

Workflow Automations

Two bots that have been quietly running on n8n Cloud

A bilingual Telegram grocery-list bot backed by Postgres, and a flight price monitor that watches a Google Sheet wishlist and alerts when fares move.

About

I'm a software engineer who likes the messy half of the problem: the retailer that blocks your scraper, the video with a scoreboard you have to read with OCR, the API that times out before your job finishes.

Most of what's here started as a question I couldn't answer by reading. Can a genetic algorithm learn to play a platformer? Can you get a usable price comparison out of four websites that don't want to give you one? Each one turned into something that runs.
