Helping cheap cameras spot obstacles faster

Shrinking a photo before the software looks at it lets slow, inexpensive devices find obstacles about 39% faster. The research was published at PCSC 2025, and you can try the demo on a street scene of your own.

Finds the code nobody uses any more

A VS Code extension that points out exported code with nothing referencing it, the moment you save. The dead line gets a note beside it with a one click delete, and a colour coded map shows where in the project the unused code has collected.

Everything you own and owe, in pesos

Cash, investments, property and debt on one page, with a month by month history and a savings goal. The pace it reports is worked out only from readings you actually saved, so it says when a target is out of reach instead of inventing a projection.

Keeps track of stock, orders and bills

One place for a shop to manage its products, orders, invoices and customer questions. Everyone gets their own view, whether they are the owner, a supplier or a buyer, and payments and shipping are handled inside the app.

A shared board for team projects

A task board that stops a team from piling too much work into one stage at a time. Cards move in real time for everyone watching, and timeline charts show what has to finish before the next thing can start.

Freelance escrow on the Stellar blockchain

A smart contract holds the client's crypto until the work is turned in and approved, so neither side has to just trust the other. If they disagree, a neutral arbiter can step in and decide who gets paid.

Control YouTube by waving your hand

Your webcam watches your hand so you can control a video without touching anything. Make a fist to play or pause, and raise or lower your hand to change the volume. It works whether you are right in front of the screen or across the room.

    • Audit client websites for crawlability, indexation, on-page, and Core Web Vitals issues using Ahrefs Site Audit, PageSpeed Insights, and manual code review; deliver each audit as a prioritized fix list ranked by impact and effort.
    • Analyze Google Search Console and GA4 data to track search performance over time, isolate pages and queries that are gaining or losing clicks, and explain the cause behind each movement.
    • Use AI tools to summarize large SEO exports, cluster queries by intent, and draft first-pass recommendations, then validate every output against the source data before it reaches a client.
    • Run competitor comparisons in Ahrefs across keywords, backlinks, and content, and turn the gaps found into concrete content and optimization opportunities.
    • Write findings as plain-language reports and recommendation decks for stakeholders and project teams, so non-technical readers can act on them without a follow-up meeting.
